F.D.A.’s Project Optimus Adds to Complexity and Length of Mandated Clinical Trials, Further Burdening Innovative Startups

One of Joseph Schumpeter’s profound subtle points in the key chapter 7 of Capitalism, Socialism and Democracy is that the kind of thinking and rules that aim for optimization, restrict the kind of creative, inspired thinking or improvisational pivoting that results in the greatest and fastest progress and flourishing. (My interpretation of Schumpeter.)

Great leaps forward have tended to originate from small startups. But increasing the size, length, and costs of mandated clinical trials, as the F.D.A. is doing with “Project Optimus,” will make it harder for small startups to survive, let alone flourish.

(p. B2) For years, Food and Drug Administration officials have expressed concern that cancer drug doses are often too high, leading to unnecessary side effects. An FDA program launched in 2021, Project Optimus, requires companies to re-examine how they set doses of cancer treatments.

This typically involves larger clinical trials to test doses to find those that optimally balance safety and efficacy. Entrepreneurs support the aim, but some fear the initiative will add time and cost to drug development, putting startups at a further disadvantage to larger competitors.

“I don’t think anybody disagrees with the idea that we’re trying to find the best thing for the patient,” said David Bearss, chief executive of biotechnology startup Halia Therapeutics. “I hope it doesn’t have unintended consequences of actually suppressing innovation.”

. . .

Because Project Optimus is still relatively new it will take a while for its full impact to be known. But it will likely add six to 12 months to the drug-development process, said Tara Raghavan, a pharmaceutical patent lawyer and partner with law firm Benesch Friedlander Coplan & Aronoff.

Mail-Order Drugs and Supplements Degrade in Transit Heat

Researchers have identified many chemicals that should be beneficial to health in a variety of ways. For instance some should help fight cancer, others should reduce heart disease. Often researchers present plausible stories about the mechanism through which the positive effects occur. But one puzzle is that empirical (observational) evidence often suggests that the positive effects occur when the chemicals are consumed in foods, but not when it is consumed in pill, capsule, powder or liquid supplements. One speculation is that sometimes the chemicals in food are complemented by other as-yet-unidentified chemicals that enable or enhance the main chemical’s effects. These other chemicals are as-yet-unidentified “adjuvants.”

But the evidence in the story quoted below stimulates an alternative speculation. Consumers know when food has gone bad by its taste, smell, texture, and appearance. inform consumers when the food has gone bad and should not be consumed. With pills, such direct evidence is harder to perceive. So consumers are more likely to swallow pills that have gone bad than they are to swallow food that has gone bad.

When the F.D.A. approves a drug, after expensive testing, we assume that the drug is good for us. We let down our guard and trust the drug. If instead we operated under the caveat emptor rule, we would buy our drugs and supplements from physical stores that have a reputation for logistical excellence (for instance Walmart and Costco).

the F.D.A. is not good at protecting us, and because we trust them, we are no longer good at protecting ourselves.

(p. A1) Mail-order pharmacies say that their packaging is weather resistant and that they take special precautions when medication “requires specific temperature control.” But in a study published last year, independent pharmaceutical researchers who embedded data-logging thermometers inside simulated shipments found that the packages had spent more than two-thirds of their transit time outside the appropriate temperature range, “regardless of the shipping method, carrier, or season.”

. . .

(p. A17) The Times spoke to more than a dozen patients who had received medications they suspected were damaged by heat and humidity during transportation, some of whom experienced serious medical issues after consuming the drugs. Most said they had received their medications in manila envelopes or plastic shipping bags with no additional insulation. They spoke about finding pill bottles in metal mailboxes or tossed onto their front porches, leaving them unsure of how long the drugs had been baking in the sun. Others said they routinely stayed home to watch for drop-offs but found that the medications arrived already warm to the touch.

. . .

In Missouri, Loretta Boesing received a shipment of a liquid immunosuppressant medication for her son, who had a liver transplant, in 102-degree weather in only a plastic envelope. Soon after, his health began waning, and his body began to reject the liver. During a two-week hospital stay, he began receiving the medications from the hospital pharmacy instead and began to recover.

Several years after the ordeal, Ms. Boesing’s insurance changed, and the new services were administered by CVS Caremark. She filed several appeals to the company to allow her to continue picking up the medication at the hospital pharmacy. But the request was denied, she said, and the medication again arrived without an ice pack, warm. She said her son’s liver lab tests had begun to elevate again.

She wept on a call with a CVS Caremark representative, which she recorded and shared with The Times. “I am begging you right now: Please do not let me lose my son,” she says on the call.

Michael DeAngelis, a spokesman for CVS Health, said he was not able to comment on the specific case because of patient privacy laws but added that the company customizes its packaging using a “sophisticated algorithm” that accounts for both F.D.A. and manufacturer data.

“There are hundreds of different possible packaging combinations that we can use to help mitigate weather and temperature issues,” he said.

Ms. Boesing went on to start the nonprofit group Unite for Safe Medications.

Rebecca Nierengarten, 39, of Maplewood, Minn., was in medical school when she fell ill with a dangerous autoimmune disease that causes extreme muscle weakness. She said her insurance company had forced her to switch from hospital infusions of an immunoglobulin product called Privigen to home delivery of the drug, and every summer, her condition worsened so drastically that she could not stand up from a chair without assistance and struggled to swallow.

“It’s a protein medication — proteins denature with heat,” she said. “If you have a biology degree, you know that.”

. . .

Researchers have been aware of potential effects of heat exposure on medications since at least the 1990s. Between June and August of 1996, United States Pharmacopeia — the nonpartisan group that sets national standards for drug handling — packaged and mailed electronic temperature and humidity indicators to various parts of the country to determine whether drugs were being subjected to worrisome conditions.

The results, shared with a task force of the National Association of Boards of Pharmacy, showed that more than 90 percent had exceeded the appropriate temperature range and that more than a quarter of those had been exposed to what was considered “excessive heat,” above 104 degrees Fahrenheit. The packages were also exposed to significant spikes in humidity.

But representatives from the Pharmaceutical Care Management Association, which lobbies for the pharmacy benefit managers that oversee drug benefits for many insurance plans, were present at the meeting, and the task force decided against acting.

In the more than two decades since, global temperatures have risen, and so have the number of people who receive medications by mail through the big pharmacy benefit managers, many of which are owned by companies that also own mail-order pharmacies.

Harold Ridley’s Innovative Project Was to Replace a Cataract with a Plexiglass Lens

I am currently working on a book on medical entrepreneurship. Harold Ridley deserves inclusion.

Innovative entrepreneurs often observe anomalies and realize how the anomalies can be put to good use, where others would not notice the anomalies, or would notice them, shrug, and forget. (In Ridley’s case the anomalie was that the plastic fragments in Cleaver’s eyes “weren’t causing any inflammation or infection.”)

Pasteur famously said that ‘chance favors a prepared mind.’ If he had read Kirzner, he might have added ‘chance also favors an alert mind.’ (Kirzner’s account of entrepreneurship emphasizes the importance of entrepreneurial alertness.)

(p. A17) On Aug. 15, 1940, Royal Air Force pilot Gordon Cleaver scrambled into the cockpit of his Hawker Hurricane and lifted into the sky.  . . .  He was shot down over Winchester. Enemy bullets shattered his canopy, showering debris into his eyes. Flying blind and in excruciating pain, Cleaver managed to escape his doomed plane and parachute to the ground.

. . .

Cleaver’s damaged eyes were examined by a 34-year-old ophthalmologist, Harold Ridley. Shards of Plexiglas from his shattered canopy remained in the pilot’s eyes. This was a disaster. Foreign bodies in the eye such as lead or shrapnel usually caused inflammation or infection so severe that the eyes often had to be removed. But Ridley noticed something peculiar: The fragments of clear plastic weren’t causing any inflammation or infection. They sat quietly inside Cleaver’s eyes, glistening in the light of the ophthalmoscope. This was a shocking discovery.

Ridley examined Cleaver multiple times. The pilot’s sight was severely damaged, but the Plexiglas remained inert in his eyes, causing no inflammation. In 1948, while Ridley was removing a cataract—a clouding of the eye’s lens—for another patient, the memory of Cleaver’s case sparked an epiphany. A medical student observing the operation said, “It’s a pity you can’t replace the cataract with a clear lens.” Ridley recalled the well-tolerated Plexiglas in Cleaver’s eyes and realized that he could use the material to make an intraocular lens that the body wouldn’t reject.

. . .

His invention has saved the sight of millions. But instead of stirring professional acclaim, Ridley’s invention was a disaster for his career. The ophthalmology establishment labeled him a heretic.

Leaders in the field accused him of malpractice, ridiculed him at science conferences and poisoned colleagues against his ideas. They argued that the procedure was a “time bomb” and that “manufacturers should be prosecuted for supplying implants.” Ridley worked for decades to improve his operation and gain converts, but fell into a deep depression. When he retired in 1971, he considered his career a failure.

The Hurdles to Getting Paxlovid Reduce Its Use

Requiring prescriptions for most drugs is defended as a way to protect patients. But getting a quick physician appointment, making the appointment, and then getting the prescription filled, can all take nontrivial amounts of time and effort, especially burdensome for the poor or for those with work or family duties. Many drugs, such as Paxlovid for Covid, only work if taken in the early days of the disease. As a result, few people end up taking Paxlovid.

How does that protect patients?

If we respected the right of adult patients to make their own decisions, as soon as they had symptoms of Covid, they could go to a pharmacy and purchase Paxlovid.
Showing respect would both be moral, and would be more effective against the disease.

(p. A19) . . . Paxlovid seems to reduce the chance of hospitalization and death from Covid by more than 85 percent, . . .

. . .

But having drugs, especially highly effective ones like Paxlovid, is critical. And for these medications to succeed they must be taken correctly. People need to start them within five days of an infection, and because of the deficiencies of our testing system and other problems in health care, beginning treatment that quickly is difficult.

. . .

If you test positive, you can’t go straight to a pharmacy for the drug therapy like you did for the test. You need a prescription for the medication, which often requires a doctor’s visit. That presupposes that you have a doctor (many people don’t), and that there’s an appointment available. Before the pandemic, fewer than half of people in the United States could get a same-day or next-day appointment with their provider when they were sick.

If you’re lucky enough to traverse this gantlet successfully, though, you now need to get your prescription filled. Most insurance will restrict where you can get your medications paid for, and it’s hit or miss whether that pharmacy will have pills in stock. If not, hopefully they’ll be in a few days later, but those are precious days.

Too few people understand that much of the U.S. health care system is set up to make it harder for people to get care — an attempt to drive down overall health care spending. That’s why your insurance likely has higher deductibles than it used to, and more visits come with co-pays or coinsurance. But poorer people have a harder time covering these costs, so this worsens disparities and makes it harder for those who need help the most to get it.

We see this play out with Covid-19 treatments. A recent study looked at how efficiently and effectively Medicare beneficiaries (all of whom were elderly) received monoclonal antibody therapy from 2020 to 2021 for Covid. It found that those at highest risk were the least likely to be treated, in large part because it was difficult to navigate these hurdles within the 10 days from infection that treatment requires.

It doesn’t need to be this way.  . . .  Pharmacists could be more empowered to talk to patients about whether the pills are safe for them and distribute pill packs without a prescription if patients qualify.

Disintermediate Healthcare

Many of the problems of our broken healthcare system could be fixed if insurers and healthcare providers were competing directly and transparently for the dollars of patients. But their are middlemen between patients and providers–mostly employers and governments. The goals and knowledge of the payers overlap, but are not the same. The payers may prioritize lowering their costs and may not care as much, or even know, the full costs to the patients.

The patients have a much better knowledge of the value of the healthcare or insurance that they are receiving, but they are very constrained in their ability to switch to insurers or healthcare providers who provide better services, or do so more efficiently. For many workers healthcare and health insurance are bundled with their work. They can leave their work, but other components of the bundle matter.

And nothing is transparent.

The fancy word for cutting out the middleman is “disintermediation.”

(p. 1) Weeks after undergoing heart surgery, Gail Lawson found herself back in an operating room. Her incision wasn’t healing, and an infection was spreading.

At a hospital in Ridgewood, N.J., Dr. Sidney Rabinowitz performed a complex, hourslong procedure to repair tissue and close the wound.

. . .

But the doctor was not in her insurance plan’s network of providers, leaving his bill open to negotiation by her insurer. Once back on her feet, Ms. Lawson received a letter from the insurer, UnitedHealthcare, advising that Dr. Rabinowitz would be paid $5,449.27 — a small fraction of what he had billed the insurance company. That left Ms. Lawson with a bill of more than $100,000.

“I’m thinking to myself, ‘But this is why I had insurance,’” said Ms. Lawson, who is fighting UnitedHealthcare over the balance. “They take out, what, $300 or $400 a month? Well, why aren’t you people paying these bills?”

The answer is a little-known data analytics firm called MultiPlan. It works with UnitedHealthcare, Cigna, Aetna and other big insurers to decide how much so-called out-of-network medical providers should be paid. It promises to help contain medical costs using fair and independent analysis.

But a New York Times investigation, based on interviews and confidential documents, shows that MultiPlan and the insurance companies have a large and mostly hidden financial incentive to cut those reimbursements as much as possible, even if it means saddling patients with large bills. The formula for MultiPlan and the insurance companies is simple: The smaller the reimbursement, the larger their fee.

Here’s how it works: The most common way Americans get health coverage is through employers that “self-fund,” meaning they pay for their workers’ medical care with their own money. The employers contract with insurance companies to administer the plans and process claims. Most medical visits are with providers in a plan’s network, with rates set in advance.

But when employees see a provider outside the network, as Ms. Lawson did, many insurance companies consult with MultiPlan, which typically recommends that the employer pay less than the provider billed. The difference between the bill and the sum actually paid amounts to a savings for the employer. But, The Times found, it means big money for MultiPlan and the insurer, since both companies often charge the employer a percentage of the savings as a processing fee.

In recent years, the nation’s largest insurer by revenue, UnitedHealthcare, has reaped an annual windfall of about $1 billion in fees from out-of-network savings programs, including its work with MultiPlan, according to testimony by two of its executives.

. . .

(p. 18) In some instances, the fees paid to an insurance company and MultiPlan for processing a claim far exceeded the amount paid to providers who treated the patient. Court records show, for example, that Cigna took in nearly $4.47 million from employers for processing claims from eight addiction treatment centers in California, while the centers received $2.56 million. MultiPlan pocketed $1.22 million.

. . .

In examining MultiPlan’s dominant role in this secretive world, The Times reviewed more than 50,000 pages of confidential corporate records, legal filings, claims information and other documents. The Times also interviewed more than 100 patients, doctors, billing specialists, advisers to employer health plans and former MultiPlan employees.

. . .

Mary Reinbold Jerome had been diagnosed with ovarian cancer at age 62 and received treatment at Memorial Sloan Kettering. Because the hospital was outside her plan’s network, she was billed tens of thousands of dollars.

. . .

She stood beside Andrew M. Cuomo, then the attorney general, as he announced his office’s blistering conclusions: A payment system riddled with conflicts of interest had been shortchanging patients, and at its core was a data company called Ingenix. Insurers used the company, a UnitedHealth subsidiary, to unfairly lower their payments and shift costs to patients, the probe found.

. . .

But amid the triumph, a key detail in the attorney general’s agreements with insurers largely escaped notice: The companies were required to use the nonprofit database for only five years.

When that term expired in 2014, MultiPlan was well positioned to capitalize.

For decades, the company, founded in 1980, offered a traditional approach to managing out-of-network claims by negotiating rates with doctors. Insurers got discounts and assurances that patients would not have to make up the difference.

But after MultiPlan’s founder sold it to private equity investors in 2006, the company pursued a more aggressive approach. It embraced pricing tools that used algorithms to recommend lower payments, and no longer protected patients from having to pay the difference, documents show.

Meanwhile, private equity ramped up investments in physician groups and hospitals and, in some instances, began billing for extraordinary sums. Once insurers were no longer obligated to use the nonprofit database, FAIR Health, they began looking for ways to combat that billing and other charges they considered egregious.

. . .

Internal documents show that UnitedHealthcare began a campaign to persuade employers to switch from FAIR Health. In a 2019 email, a UnitedHealthcare senior vice president emphasized creating a “sense of urgency” and helping companies still using FAIR Health “understand they don’t want to be on that program anymore.”

UnitedHealthcare had a big incentive to encourage this change. When it processed claims from employer plans using FAIR Health, the insurer collected no additional fee, according to legal testimony. But when it used MultiPlan, documents show, it typically charged employers 30 to 35 percent of the difference between the billed amount and the portion paid.

MultiPlan, too, charged a percentage of the savings, meaning it could make more by recommending lower payments. (FAIR Health charged a flat fee.)

. . .

(p. 19) Some providers said they had begun requiring payment upfront or stopped accepting patients with certain insurance plans because appealing for higher payments can be time-consuming, infuriating and futile. Others have tried to sue insurers or MultiPlan. Dr. Rabinowitz, who repaired Ms. Lawson’s incision, hopes to collect the remaining balance from UnitedHealthcare in an ongoing case.

Surprise bills for some types of care are no longer an issue, insurers said, thanks to the law that went into effect in 2022. Brittany Perritt didn’t realize the anesthesiologists at her 3-year-old’s brain tumor treatments in 2020 were out-of-network until the claims went to MultiPlan. If that care occurred today, she likely would be spared the calls from debt collectors, because she didn’t go out of network by choice.

But MultiPlan assured investors shortly before the law’s passage that it was likely to have “limited impact” on the company. In fact, MultiPlan said, 90 percent of its revenue involved out-of-network claims that wouldn’t be affected.

. . .

Even when patients figured out where to direct complaints — the Employee Benefits Security Administration — they described the process as draining and mostly fruitless.

. . .

Insurers can set negotiation parameters for MultiPlan, including not negotiating at all, records and interviews show. Multiple providers and billing specialists said that in recent years they had increasingly been told their claims weren’t eligible for negotiation.

“It wasn’t this bad before,” said Tiffany Letosky, who oversees a small practice specializing in surgeries for endometriosis and gynecologic cancers.

Former MultiPlan negotiators said their bonuses had been linked to their success at reducing payments, incentivizing a hard-line approach.

Ms. Young, the former negotiator critical of the process, said she had occasionally called a provider from a cellphone — knowing that her work line was recorded — and advised against accepting her own offer.

Another former negotiator said the pressure to get bigger discounts had made her physically ill. “It was just a game,” she said. “It’s sad.”

Rickets Is Now Rare Because Vitamin D Is Easy to Get

(p. A15) Rickets is one of those diseases that seem incredibly old-fashioned. It’s difficult to comprehend, now, how widespread this bone ailment once was: In some cities less than a century ago, 90% of children showed symptoms of rickets during wintertime. But ubiquity has its benefits. In “Starved for Light,” Christian Warren convincingly argues that modern medicine would be unrecognizable without the many advances in treatment that trace their roots to this once-widespread disease.

Rickets results from a lack of vitamin D, which we need to help shuttle calcium and phosphorus into our bones. Our bodies manufacture vitamin D whenever ultraviolet sunlight hits our skin; we can also get it through food. A deficiency in vitamin D causes the softening and bending of bones characteristic of rickets; victims are often left bowlegged or knock-kneed, or with curved spines or misshapen pelvises. The worst cases leave babies unable to crawl or even sit up straight.

. . .

Given how disgusting cod-liver oil tastes, some countries began combating rickets by adding vitamin D to milk in the 1930s—an odd choice, since milk contains no vitamin D naturally. (Amusingly, Mr. Warren calls the practice an “in uddero” health intervention.) The choice seems even odder, the author wryly notes, when there’s a much simpler solution to preventing rickets: going outside for a few minutes. Instead, we’ve effectively turned “a dairy product into a drug-delivery device,” severing the ancient interplay between “sun, skin, and bone.”

Trial-and-Error Exploration of Venoms Can Yield Useful Drugs

Several decades ago the fastest path to medical advance was claimed to be theoretical science. That approach has not paid off as richly as predicted.
But it may still. (When Pets.com failed, some said we should have known you cannot make money selling pet supplies online. But now Chewy.com succeeds.) Nonetheless the contempt the theoreticians heaped upon empirical trial-and-error research was not justified. Much is still left to be learned by that method, as exemplified in the passages quoted below.

(p. D1) Efforts to tease apart the vast swarm of proteins in venom — a field called venomics — have burgeoned in recent years, and the growing catalog of compounds has led to a number of drug discoveries. As the components of these natural toxins continue to be assayed by evolving technologies, the number of promising molecules is also growing.

“A century ago we thought venom had three or four components, and now we know just one type of venom can have thousands,” said Leslie V. Boyer, a professor emeritus of pathology at the University of Arizona. “Things are accelerating because a small number of very good laboratories have been pumping out information that everyone else can now use to make discoveries.”

She added, “There’s a pharmacopoeia out there waiting to be explored.”

. . .

(p. D8) The techniques used to process venom compounds have become so powerful that they are creating new opportunities. “We can do assays nowadays using only a couple of micrograms of venom that 10 or 15 years ago would have required hundreds of micrograms,” or more, Dr. Fry said. “What this has done is open up all the other venomous lineages out there that produce tiny amounts of material.”

There is an enormous natural library to sort through. Hundreds of thousands of species of reptile, insect, spider, snail and jellyfish, among other creatures, have mastered the art of chemical warfare with venom. Moreover, the makeup of venom varies from animal to animal. There is a kind of toxic terroir: Venom differs in quantity, potency and proportion and types of toxin, according to habitat and diet, and even by changing temperatures due to climate change.

Venom is made of a complex mix of toxins, which are composed of proteins with unique characteristics. They are so deadly because evolution has honed their effectiveness for so long — some 54 million years for snakes and 600 million for jellyfish.

. . .

Numerous venom-derived drugs are on the market. Captopril, the first, was created in the 1970s from the venom of a Brazilian jararaca pit viper to treat high blood pressure. It has been successful commercially. Another drug, exenatide, is derived from Gila monster venom and is prescribed for Type 2 diabetes. Draculin is an anticoagulant from vampire bat venom and is used to treat stroke and heart attack.

The venom of the Israeli deathstalker scorpion is the source of a compound in clinical trials that finds and illuminates breast and colon tumors.

Some proteins have been flagged as potential candidates for new drugs, but they have to journey through the long process of manufacture and clinical trials, which can take many years and cost millions of dollars. In March [2022], researchers at the University of Utah announced that they had discovered a fast-acting molecule in cone snails. Cone snails fire their venom into fish, which causes the victims’ glucose levels to drop so rapidly it kills them. It holds promise as a drug for diabetes. Bee venom appears to work with a wide range of pathologies and has recently been found to kill aggressive breast cancer cells.

For the Last 30 Years, a Cure for Type 1 Diabetes “Is Just Five Years Away”

The article quoted below describes the “despair” of many with chronic diseases, and there willingness to “become human guinea pigs,” taking new therapies that may have risks, but also have some unknown change of a cure.

We should allow adults to make this choice. First because we respect their right to freedom. Second because we do not want to take away their hope, which is a key component of well-being. Third because allowing volunteers to try bold uncertain therapies, we will progress further and faster to cures.

Note that substantial funding for bold experiments is from a foundation headed by a doctor who himself has Type 1 diabetes. He has skin in the game, a sense of urgency.

Note also that a small pharma firm made progress, and convinced sufferers of the disease that the firm sincerely was mission-oriented. But ViaCyte was also severely financially constrained, given the huge costs of Phase 3 clinical trials. They were bought by Vertex, a company that started out small with the same mission-oriented passion (see Worth 1994) but seemed to lose some of that passion as they grew, due to the need to hire those who were good at raising money and dealing with regulators (see Worth 2014). Is it meaningful that an early success of Vertex was the drug Kalydeco for the relatively rare cystic fibrosis disease and that much of their financing was from a foundation of parents of children with cystic fibrosis, parents who felt plenty of urgency.

The odds are against Vertex curing Type 1 diabetes, but I hope they beat the odds.

If we want to better the odds for a cure, we should make drug development an order of magnitude cheaper by ending the mandate for Phase 3 clinical trials (in other words, we regulate only for safety, no longer for efficacy). Then small, passionate, entrepreneurial firms like ViaCyte can survive, thrive, and bring cures to market. Otherwise the financial hurdles will cause small firms like ViaCyte to sell out to large less entrepreneurial firms like Vertex.

(p. D5) In the three decades since she was first diagnosed with Type 1 diabetes, Lisa Hepner has clung to a vague promise she often heard from doctors convinced medical science was on the cusp of making her body whole again. “Stay strong,” they would say. “A cure is just five years away.”

. . .

“‘The cure is five years away’ has become a joke in the diabetes community,” Ms. Hepner said. “If it’s so close, then what’s taking so long? And in the meantime, millions of us have died.”

. . .

Therapies developed from human embryonic stem cells, many experts say, offer the best hope for a lasting cure. “The Human Trial” offers a rare glimpse into the complexities and challenges of developing new therapies — both for the patients who volunteer for the grueling clinical trials required by the Food and Drug Administration, and for the ViaCyte executives constantly scrambling to raise the money needed to bring a new drug to market. These days, the average cost, including the many failed trials along the way, is a billion dollars.

At a time when the soaring price of insulin and other life-sustaining drugs has tarnished public perceptions of the pharmaceutical industry, the film is also noteworthy for its admiring portrayal of a biotech company whose executives and employees appear genuinely committed to helping humanity.  . . .

. . .

“The Human Trial,” which can also be viewed online, has become a rallying cry for Type 1 patients, many of whom believe only greater visibility can unleash the research dollars needed to find a cure.

Those who have seen the film have also been fortified by seeing their own struggles and dashed hopes reflected in the journeys of the film’s two main subjects, Greg Romero and Maren Badger, who became among the first patients to have the experimental cell pouches implanted under their skin.

The despair that drives them to become human guinea pigs can be hard to watch. Mr. Romero — whose father also had the disease, went blind before he was 30 and then died prematurely — confronts his own failing vision while grappling with the pain of diabetes-related nerve damage. “I hate insulin needles, I hate the smell of insulin. I just want this disease to go away,” Mr. Romero, 48, says numbly at one point in the film.

. . .

. . . there is more recent news that did not make it into the film. [In July 2022], ViaCyte was acquired by Vertex, the competing biotech company that has been developing its own stem-cell treatment. That treatment has shown early success, and last year the company announced that a retired postal worker who took part in clinical trials had been cured of Type 1 diabetes.

After almost a lifetime of hearing a cure was just around the corner, Dr. Aaron Kowalski, chief executive of the JDRF (Juvenile Diabetes Research Foundation), the world’s biggest funder of Type 1 research, counts himself as an optimist. A dozen more drug companies are pursuing a cure than a decade ago, he said, and the organization this year plans to spend $100 million on cure research. “It’s not a matter of if this will happen, it’s a matter of when,” said Dr. Kowalski, who is a scientist and has had the disease since childhood, as has a younger brother. “Our job is to make sure it happens faster.”

Using the Blood of the Young to Rejuvenate the Organs of the Old

The strange longevity therapy described in the passages quoted below, are hard to test, especially if started at a time in life early enough to do the most good.

Phase 3 clinical trials to establish the efficacy of a therapy are in general very expensive, and they are especially very expensive for therapies aimed at extending lifespan. To know the efficacy of such therapies you have to run the trial for many years, before you can learn the lifespans of all of those in the trial.

This may be one reason why pharma firms instead invest in incremental improvements in health tested for those predicted to be near the end of their lives.

Azra Raza claims that the most promising therapies for cancer would be those applied early in the disease. But it is precisely these candidate therapies that would be most expensive to test through a hyper-expensive Phase 3 clinical trial. The result? Unnecessarily slow progress in curing cancer.

(p. B3) Several years ago, scientists studying aging at the Harvard Stem Cell Institute used a somewhat Frankensteinian technique known as parabiosis — surgically joining a young mouse and an old mouse so that they share blood — to see what would happen to the heart and skeletal muscle tissue. They knew from previous research that putting young blood in old mice caused them to grow biologically younger, and that young mice exposed to old blood aged faster.

The Harvard researchers, Amy Wagers and Dr. Richard Lee, found that the old mouse’s heart tissue had been repaired and rejuvenated, becoming young again. In fact, the size of the old mouse’s heart had reduced to that of a young heart.

“We all wondered, what’s the magic stuff in the blood?” said Lee Rubin, a professor of stem cell and regenerative medicine at Harvard and the co-director of the neuroscience program at the Stem Cell Institute. The “magic” they identified was a protein, GDF11, one of tens of thousands produced in the human body.  . . .  The scientists’ discoveries were published in the journals Cell and Science in 2013 and 2014.

. . .

“We’re interested in proteins like GDF11 that are excreted into the bloodstream because those can cause changes throughout the body,” said Dr. Mark Allen, the chief executive of Elevian. “And those are the kind of changes we want.”

. . .

The initial research into the rejuvenating properties of GDF11 has gotten some pushback from the scientific community. In 2015, after Dr. Wagers and Dr. Lee had published their results, a group of researchers led by David Glass, the executive director of the Novartis Institutes for Biomedical Research in Cambridge, Mass., at the time, challenged the accuracy of their findings in an article in the journal Cell Metabolism. The Harvard researchers subsequently countered the Novartis team’s findings in another paper published later that year in the journal Circulation Research, in which the Harvard researchers cited a problem with the Novartis team’s findings.

Dr. Glass, who is now at the biotechnology company Regeneron, said in a recent email that he stands by his original work, which showed that GDF11 inhibits, rather than helps, muscle regeneration. But, he added, “our work still leaves open the possibility that there could be positive effects of GDF11 in particular settings.”

Dr. Allen said that since the original controversy, Elevian’s research team has reproduced and extended its original findings in multiple studies, but none have yet been published in peer-reviewed journals. However, institutions unrelated to Elevian have conducted and published many preclinical studies demonstrating the therapeutic efficacy of rGDF11 (the form of GDF11 developed in a lab) in treating age-related diseases.

. . .

A significant challenge lies ahead for all of these companies: Commercializing a drug for aging is nearly impossible because the F.D.A. doesn’t recognize aging as a disease to be treated. And even if it were considered a disease, the clinical studies required to prove that a treatment for it worked would take many years.

“It is likely that clinical studies to see if some drug slows aging — and thereby delays the many consequences of aging — would take a long time,” Dr. Miller said.

. . .

The next big hurdle for Elevian is scaling its manufacturing, which requires specialized equipment and conditions. So much research is being conducted in biotech that contract manufacturers are “full up,” Dr. Allen said. “They are busy with Covid-related work, and there has been a lot of funding in biotech generally,” he added. “So it’s a challenge finding the space that meets our specifications.”

. . .

“By targeting fundamental mechanisms of aging, we have the opportunity to treat or prevent multiple aging-related diseases and extend the health span,” he said. “We want to make 100 the new 50.”

W.H.O. Ignored Those Who Knew Covid Was Airborne

The article quoted below provides more evidence that the World Health Organization (W.H.O.) failed to protect world health during the Covid pandemic. Its funding and decision-making processes made failure highly likely.

In the absence of W.H.O, how can we learn quickly of potential pandemic threats from around the world? The Covid book co-authored by Ridley documents quick and effective Twitter (now X) networks that spread and evaluated Covid information. Maybe a proof of concept?

(p. D3) In early February 2020, China locked down more than 50 million people, hoping to hinder the spread of a new coronavirus. No one knew at the time exactly how it was spreading, but Lidia Morawska, an expert on air quality at Queensland University of Technology in Australia, did not like the clues she managed to find.

It looked to her as if the coronavirus was spreading through the air, ferried by wafting droplets exhaled by the infected. If that were true, then standard measures such as disinfecting surfaces and staying a few feet away from people with symptoms would not be enough to avoid infection.

Dr. Morawska and her colleague, Junji Cao at the Chinese Academy of Sciences in Beijing, drafted a dire warning. Ignoring the airborne spread of the virus, they wrote, would lead to many more infections. But when the scientists sent their commentary to medical journals, they were rejected over and over again.

“No one would listen,” Dr. Morawska said.

It took more than two years for the World Health Organization to officially acknowledge that Covid spread through the air.

Healthcare Innovations Can Be Effective AND Cheap

Many are resigned to accept our current mess of a healthcare system because they fear that if the system was changed into a fully free market system they would not be able to afford anything approaching their current level of healthcare. But they do not understand what would change. If patients paid for their own healthcare there would be competition to provide cheaper healthcare services to the many. Henry Ford got rich finding ways to make cars better and cheaper. Bill Gates got rich mainly by making adequate operating systems cheaper.

If we made healthcare a free market, then healthcare would find its Henry Ford and Bill Gates. If patients directly paid for healthcare, then healtcare services would be more consumer oriented–for instance the value of patients’ time would be respected. Medical entrepreneurs would compete to bring us more cures and cheaper cures.

The problem is not that we are “fixated on profits” as is suggested in the last paragraph quoted below. The problem is that our non-market healthcare system creates perverse incentives and perverse regulatory constraints, so that simple frugal innovations are not rewarded.

[Below I first quote a few passages from The New York Times obituary of Cash, and then from The Wall Street Journal obituary of Cash.]

(p. A21) Richard A. Cash, who as a young public-health researcher in South Asia in the late 1960s showed that a simple cocktail of salt, sugar and clean water could check the ravages of cholera and other diarrhea-inducing diseases, an innovation that has saved an estimated 50 million lives, died on Oct. 22 at his home in Cambridge, Mass. He was 83.

. . .

Dr. Cash, the son of a doctor, arrived in East Pakistan, today Bangladesh, in 1967 as part of a project through the U.S. Public Health Service. There he worked with another young American doctor, David Nalin, to respond to a cholera outbreak outside the capital, Dhaka.

The two had already been researching a simple oral rehydration therapy and knew of other, previous efforts, all of which had failed. But they believed that the therapy held promise, especially in the face of mounting deaths.

They realized that a main problem was volume: Past efforts had resulted in too little or too much hydration. Dr. Cash and Dr. Nalin conceived a trial in which they carefully measured the amount of liquid lost and replaced it with the same amount, mixed with salt and sugar to facilitate absorption.

They divided 29 patients into three groups, with one group receiving an IV drip, another an oral treatment through a tube, and the third an oral treatment by drinking from a cup.

Other doctors and nurses found their experiment bizarre and tried to stop them. But Dr. Cash and Dr. Nalin persisted, splitting the work between them in two 12-hour shifts, to ensure the integrity of the trial.

The results were definitive: Only three of the tubed patients — and only two who drank the solution — needed additional IV treatment.

. . .

“We’re enamored by high technology,” he said at the Council on Foreign Relations. “And we’re not in love with low-tech. Low-tech is always seen in our eyes as second-class. Why would you do this, when you could do that? And I would argue just the opposite.”

For the full obituary from The New York Times that is quoted above, see:

Clay Risen. “Richard A. Cash, 83, Who Saved Millions From Dehydration, Dies.” The New York Times (Monday, November 4, 2024): A21.

(Note: ellipses added.)

(Note: the online version of the obituary has the date Nov. 2, 2024, and has the title “Richard A. Cash, Who Saved Millions From Dehydration, Dies at 83.”)

(p. C6) Half a liter of water, plus a pinch of salt and a fistful of sugar. As scientific insights go, it can’t compare to the intricate equations developed to split the atom or map the planets’ paths. But its simplicity was crucial to its monumental impact.

That simple solution—the cornerstone of Oral Rehydration Therapy, or ORT—has proved extraordinary in staving off and reversing the devastating consequences of dehydration caused by cholera and other diarrheal diseases, saving tens of millions of lives since its development nearly six decades ago. In 1978, an editorial in the Lancet called ORT “potentially the most important medical advance of the century.”

. . .

Cash saw this ethos of simplicity and accessibility as instructive for a western medical system that’s infatuated with high-tech solutions, dismissive of low-tech ones and fixated on profits—and where, consequently, an overnight stay in the hospital for dehydration can result in a four-figure bill. “A solution that can’t be applied,” he told Harvard Magazine, “is really no solution at all.”
