### Week of September 6, 2026: Gene Editing Grows Up as Lilly Buys In and an Edit Saves a Baby

---

For years the honest knock on gene editing was that it made for great science and lousy businesses: dazzling in a lab, unproven in a clinic, and unloved by the big companies that actually sell drugs. This week that story got its clearest rebuttal yet, from one of the people who built the field. Kiran Musunuru, a University of Pennsylvania cardiologist who co-founded Verve Therapeutics, sat down for a long, plain-spoken interview and, without ever sounding like a pitch, laid out how gene editing quietly crossed the line from promise to product: a single injection that cuts cholesterol for life, a giant drugmaker paying up to own it, and a custom-built edit that pulled an infant back from a near-certain death sentence. Meanwhile, the week's Alzheimer's conversation came entirely from the skeptics. Here's what was actually said.

## TL;DR

* *Gene editing has grown up, and Big Pharma is buying in.* On *Lab Rats to Unicorns*, Verve co-founder Kiran Musunuru described a one-time base-editing shot that lowers "bad" cholesterol by 50–70% in human trials with no sign the effect fades, the therapy Eli Lilly bought outright last year, and now one of "a dozen" companies chasing gene editing for heart disease.

* *A single custom edit rescued a baby, and it's becoming a platform.* The same lab built a bespoke edit for an infant ("baby KJ") with a lethal metabolic disorder in about six months; he went home instead of waiting for a liver transplant. The FDA has now agreed to treat these one-off edits as a single "platform," the key to ever making them a real product.

* *The only Alzheimer's voice this week was a critic of the amyloid drugs.* Neurologist David Perlmutter cited a Cochrane review of 17 trials calling the benefit of the amyloid-clearing drugs "trivial," with more than 20% of patients getting brain bleeding or swelling. No bull-side launch coverage aired to balance him.

## What's new

*The story of the week: gene editing finally works as a business, not just a science project.* The most substantive discussion in our universe this week was an hour with Kiran Musunuru on *Lab Rats to Unicorns*, and it's worth the time, because he's not a pundit talking about the field, he's one of the people who built it. He co-founded Verve Therapeutics, helped invent the tools, and personally led the infant case that made headlines. What follows is his account. ([Lab Rats to Unicorns, Sep 2](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh8Xv2oVIZiVfGS0mfeYynhKIjv-2FO5iGsvS4jgxbCphBkMcJe9XjaCeImRjBmcTmguRBlgUNJcLN2-2BX3eQd-2FqnNtXi06qVcfpL6E2naCbF1rQ-3D-3DcZfQ_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUlKBM-2Bc606d2ZejbtU0CboCYyRPTgWyVGOVfooa62uVP9i2NnYxE01nCG-2BsBAbQbRbQkbeMmceHAUziQ4O1H8rbJ0U4rbszsy6MEZFvcRFocCi6EhYoM-2FufFAFD5SJA6dlmIT884c7N3HbImecPGIVTlaIbzLAqLt5YNsprplncQ-3D-3D))

Start with the heart-disease bet, because it's the biggest. Musunuru's original insight was blunt: heart attacks and strokes kill about *18 million people a year*, yet in the mid-2010s not one gene-editing startup wanted to touch "garden variety, boring cardiovascular disease"; they all chased rare genetic diseases instead. So in 2018 he co-founded Verve to do it himself. The idea is to use gene editing to switch off cholesterol-raising genes in the liver (names like PCSK9 and ANGPTL3) so a person makes far less "bad" cholesterol for good. Not a daily pill, a one-time treatment. As he put it, "once the cholesterol was down, it was down for good. It never came back up. It was one and done." ([Lab Rats to Unicorns, Sep 2](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh8Xv2oVIZiVfGS0mfeYynhKIjv-2FO5iGsvS4jgxbCphBkMcJe9XjaCeImRjBmcTmguRBlgUNJcLN2-2BX3eQd-2FqnNtXi06qVcfpL6E2naCbF1rQ-3D-3DW5VA_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUlKBM-2Bc606d2ZejbtU0CboCYyRPTgWyVGOVfooa62uVCiI0-2Fik1-2FTKXTV6FYUYO9KojF9c70-2FVvMzpxSWRFPUvLkvCw5xS5hJOlvmD9XkJ9hBT4P2iD265rKZ7N40WPpZdFt4xqBLPun9erdWfn1QEj8RbUsNJ-2F-2Fze2njEipJxDQ-3D-3D))

The lab data behind that claim escalated fast. The very first mouse test knocked out the cholesterol gene in about 90% of liver cells and dropped cholesterol roughly 40%, about what a statin does. Then, on a monkey study whose results landed on Thanksgiving Day, the editing was so efficient he initially thought his software was broken: *60–70%* of the gene copies edited, which in practice means nearly every relevant liver cell. And in human trials, he said, a single dose lowers LDL ("bad") cholesterol by *"50, 60, even 70%"*, and "if you follow these individuals for years, there's no sign that the effect is going away. I really do think it is going to be for the lifetime." His vision is almost preventive: a shot you could one day offer someone in their 20s, "almost like a vaccination... for heart disease," to push heart attacks back "by many years, if not decades."

Here's the part that matters for anyone watching the sector: the money has followed the science. *Eli Lilly acquired Verve outright in the summer of 2025.* Musunuru's read on why is the read-through worth keeping: "the only reason for a company like Lilly to buy it is because they believe in it and intend to take it forward." He thinks it could be Lilly's "big blockbuster in the 2030s," the next franchise after its GLP-1 obesity drugs eventually go off patent. And he stressed Lilly isn't alone: "By my count, there are now a dozen other companies that have cardiovascular disease as indications for gene editing drugs," which tells you the whole field now believes there's a real market here, not just a science prize. He expects "multiple options by the early 2030s."

*The second story: one custom edit, one saved infant, and the beginnings of a repeatable "platform."* This is the case that got the most press, and Musunuru walked through it in detail. Baby KJ was born in August 2024 with a rare urea-cycle disorder (CPS1 deficiency), a condition where the body can't clear ammonia, which then poisons the brain. He had "zero enzyme... no enzyme at all," an infant mortality rate above 50%, and a future confined to a hospital until he either died or got a liver transplant. Instead, Musunuru's team read KJ's exact genetic misspelling and, reusing the very same drug design they'd built for cholesterol, simply changed the molecular "address" to target his mutation. From diagnosis to treatment took about six months; he was dosed before he was seven months old. The result: a life-threatening disease turned "much milder, much more manageable," no transplant needed, hitting his milestones, discharged home. Musunuru is careful not to overclaim ("I would never say... cured"), but calls it "a real success story." ([Lab Rats to Unicorns, Sep 2](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh8Xv2oVIZiVfGS0mfeYynhKIjv-2FO5iGsvS4jgxbCphBkMcJe9XjaCeImRjBmcTmguRBlgUNJcLN2-2BX3eQd-2FqnNtXi06qVcfpL6E2naCbF1rQ-3D-3D_SQa_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUlKBM-2Bc606d2ZejbtU0CboCYyRPTgWyVGOVfooa62uVKwJBreVQMqLZs2c0d0MVFAHIxXm00bkcDA0C4fiq7MRknwcK1OFroWVa0yEu1LxFRrohV1sLwyrv9f6x-2BYI1dQIAjh9Ga2om-2Bpbr9yCpOXMbkGY1h368Kx-2BOQjZnEmZMw-3D-3D))

Why the case matters commercially is the "platform" idea. The trick is that these edits are all "the same drug, just different variations": the same fat-bubble delivery (lipid nanoparticles), the same base editor, with only a 20-letter guide changed to point at a different mutation. Musunuru said he and his collaborator spent two and a half years persuading the FDA to treat them that way, to approve the platform on a modest number of patients rather than demand a full, from-scratch safety package for every single child's bespoke edit, "and the FDA is now on board with that." That regulatory shift, plus a pending update to the law that funds the FDA (PDUFA), is what could turn heroic one-offs into an approvable, reimbursable product line for ultra-rare diseases.

*The third thread, and a name to watch: Beam Therapeutics picks up a real program.* The same platform produced a treatment for PKU (phenylketonuria), a metabolic disease affecting roughly 15,000–20,000 Americans. In humanized mice, a single dose corrected the genetic misspelling and drove the toxic amino acid from dangerously high levels down to normal *within 48 hours*. The commercially relevant news: *Beam Therapeutics took over that program, filed for FDA clearance to begin human trials, and that clearance recently came through*, so this moves from an academic paper toward an actual clinical program at a listed company.

*On Alzheimer's, the week belonged to the skeptics.* The only Alzheimer's discussion in our lanes came from neurologist David Perlmutter on *Health Longevity Secrets*, and it was a full-throated attack on the amyloid-clearing drugs, the class that includes the newly launched Leqembi and Kisunla. His ammunition was a *Cochrane review of 17 trials covering about 20,342 patients*, which he said found the drugs' effect on slowing decline was, in Cochrane's own word, *"trivial,"* while "more than 20% of individuals taking these drugs will develop either bleeding and/or swelling into the brain" (the side effect doctors call ARIA), and "some people have died getting these drugs." His bottom line: "The risk is high. The benefit is zero, virtually." He argued the drugs were approved for clearing amyloid, not for helping patients, and said the future of Alzheimer's treatment lies in the brain's immune cells (microglia), not amyloid. He also flagged the blood test *p-tau217* as a marker people should track "like our hemoglobin A1c." ([Health Longevity Secrets, Sep 1](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOjP9CN1ik2JtEuKbKTGVayLJnxObH3i-2FHH-2Bk1pD9oV6NmzAFeHTckJeAS2EWWiHIMtKxogQgju44-2Fp6enkCq5U0N42cV16b6g2wLp-2FVfH-2Fo7g-3D-3DFnol_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUlKBM-2Bc606d2ZejbtU0CboCYyRPTgWyVGOVfooa62uVNjdC5at9-2F2lEXTaP-2BPyrxvlRUdD0Px5t53NTt4WdPYxw8WTl9uvYeFSE9fGjJNSzKoHoSDRWC6-2B8N6uDFAvAFdj-2FJr0hxWhw593louH5iCs14AMvqFfIUEjTGD8jfZ1zg-3D-3D))

Worth naming plainly: this was a wellness-and-longevity podcast with a guest who has argued against amyloid for years, so it's the bear case in its strongest form, not a balanced review, and no bull-side voice answered it on air this week.

## The debate

*Gene editing: is the commercial case finally real, or still a decade of promises?* For once the bull and bear arguments came from the same, credible source. The bull case, in Musunuru's telling, is now concrete: an approved-and-selling first generation already exists across the field, a single one-time treatment can lower lifetime cholesterol by more than half, Eli Lilly paid up to own the heart-disease version, "a dozen" companies are racing behind it, and the same platform just saved a baby and produced a program Beam is carrying into the clinic. The bear case is the timeline and the economics, and he doesn't hide it: even in his own optimistic framing, the cardiovascular payoff is a "2030s" story that "will unfold over several years at a minimum," and the rare-disease editing that's most dramatic (one child at a time) has "no potential for reimbursement" as one-offs. It only becomes a business if the FDA's new platform approach actually carries all the way through to approval and payment. The honest synthesis: the science has clearly crossed over, but the cash flows still live years out and depend on a regulatory path that is promising but unproven. ([Lab Rats to Unicorns, Sep 2](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh8Xv2oVIZiVfGS0mfeYynhKIjv-2FO5iGsvS4jgxbCphBkMcJe9XjaCeImRjBmcTmguRBlgUNJcLN2-2BX3eQd-2FqnNtXi06qVcfpL6E2naCbF1rQ-3D-3DImbU_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUlKBM-2Bc606d2ZejbtU0CboCYyRPTgWyVGOVfooa62uVFwQRF-2BRTqtNfszSeOme31WpO7K-2FnzOI-2B2Bf7JEPTDGE051uKLpm7yQ7aPbRLivKSUfw-2Fco55oBMO-2BOtIdqUDSsNrPwcakMEnf6-2BYdG9MlXzyc2c7-2BdW-2FxlEkkGub1zguQ-3D-3D))

*Alzheimer's: are the amyloid drugs worth it?* This week the debate was one-sided by default: only the critic spoke. Perlmutter's case against the amyloid drugs (trivial benefit, real risk, wrong target) went unanswered on the podcasts. In fairness to the other side, the mainstream view, laid out on these shows in prior weeks, is that these drugs are the first to modify the disease at all, that the benefit compounds over years, and that careful patient selection and monitoring manage the ARIA risk. But none of that was voiced this week, so we won't pretend it was. The one adjacent data point: a diagnostic marker both camps actually agree on, the p-tau217 blood test, keeps moving toward the center of how Alzheimer's is measured.

## Names in play

* *Beam Therapeutics (BEAM), the clearest listed read-through this week.* Musunuru confirmed Beam took over the PKU base-editing program he and his CHOP collaborator developed, filed with the FDA, and recently won clearance to start human trials, a concrete pipeline step for a company whose story has been mostly future data. The 48-hour normalization in mice is the kind of early signal that made it worth Beam's while.

* *Eli Lilly (LLY), the big-pharma buyer of the heart-disease bet.* Musunuru framed the Verve acquisition as Lilly reaching for its "2030s" franchise beyond obesity. Lilly's own CEO, interviewed separately this week at the G20, described exactly that strategy, to "diversify out of [obesity], investing in technologies that can really change other diseases the way we've changed obesity... well into the 2030s." He didn't name Verve or gene editing, and most of the interview was about GLP-1 drugs and tariffs, but the one-time cholesterol edit is a textbook example of the bet he's describing.

* *The gene-editing peers (CRSP, NTLA, EDIT), flattered by imitation.* Musunuru's "a dozen companies now chasing cardiovascular editing" is the structural bull note for the whole group, even though no single peer got its own deep-dive this week. His reminder that the early leaders (CRISPR Therapeutics, Intellia, Editas) initially passed on heart disease is also a reminder that today's approved products use the oldest "scissors," while the frontier is base and prime editing.

## Read-throughs

* *In-vivo editing versus the incumbents in heart amyloidosis (ATTR).* Two cardiology podcasts spent time on ATTR amyloidosis, but on the *current* drugs, not gene editing. On *This Week in Cardiology*, the host walked through the RNA "silencers" that shut down the liver's production of the faulty TTR protein: the Helios B trial of vutrisiran cut death and cardiovascular events (hazard ratio 0.72 overall, better as a standalone at 0.67), while a newer silencer, eplontersen, actually *failed* its main trial (CARDIO-TRANSFORM). His aside is the whole read-through: these drugs cost "hundreds of thousands per year each. Each!" *JAMA*'s editors, covering the same meeting, confirmed adding a stabilizer on top of a silencer isn't "much better than either therapy alone." Why it matters for our universe: these are chronic, six-figure-a-year drugs, exactly the incumbents a one-and-done in-vivo CRISPR edit of the same TTR gene would be trying to displace. The competing modality just showed both real efficacy and its price tag.

* *Rare-disease pricing is the friend of the editing platform.* RBC Capital Markets' biotech team, on *Pathfinders in Biopharma*, made the point that rare-disease launches are where smaller biotechs can win because "a few thousand patients on drug can go a long way when rare-disease pricing often commands six- or seven-figure price tags." That's the economic engine behind Musunuru's platform vision, the same math that could make a one-child-at-a-time edit sustainable if the FDA lets it scale.

* *China and the FDA, the two swing factors for the whole tape.* The same RBC discussion flagged China's growing edge in fast, cheap early-stage drug development (pulling more M&A toward Chinese assets), and named the FDA's follow-through "when the hard decisions arrive at the upcoming PDUFAs" as a make-or-break for the biotech rally's second half. That FDA point rhymes directly with Musunuru's hope that pending PDUFA changes will smooth the path for platform gene-editing therapies.

## What changed

Last week the conversation was about the *economics* of the first approved CRISPR medicine, how a drug can sell well while its inventor still loses money. This week the frame flipped from "can gene editing ever pay?" to "the payoff is coming, here's the proof," told by an insider, with a Big Pharma acquisition, a dozen fast-followers, a rescued infant, and a Beam program entering the clinic to back it up. It's the most optimistic the gene-editing story has sounded on these podcasts in a while, and notably it came from a scientist who is scrupulous about not overclaiming. On Alzheimer's, the pendulum swung the other way: after weeks that included the mainstream diagnostic playbook, this week only the amyloid skeptics spoke.
