Al­ladapt gets $100M+ to see its all-in-one oral im­munother­a­py al­ler­gy drug through clin­i­cal tri­als

Most food al­ler­gy care in­volves avoid­ance — check­ing in­gre­di­ent la­bels, no peanut ta­bles in schools, and so on. How­ev­er, that par­a­digm has been shift­ing with oral im­munother­a­pies, or OITs for short, in which pa­tients pur­pose­ly eat a bit of their al­ler­gen in the form of a mod­i­fied pro­tein in hopes of train­ing their im­mune sys­tem to tol­er­ate it.

Al­ladapt Im­munother­a­peu­tics is cre­at­ing a sin­gle OIT for all ma­jor IgE-me­di­at­ed food al­ler­gies — “what we call the big nine,” as Al­ladapt CEO Ash­ley Dom­bkows­ki said — for milk, eggs, wheat, fish, shell­fish, peanuts, tree nuts, soy and sesame. Now, the biotech has $119 mil­lion to push that drug through clin­i­cal tri­als.

Aim­mune got the first peanut OIT for chil­dren ap­proved back in Jan­u­ary of 2020, though it faced con­tro­ver­sy for the cost of its drug, more or less a ver­sion of peanut pro­tein, that came with an an­nu­al price tag of over $10,000. And soon af­ter get­ting that ap­proval, Aim­mune was bought by Nestlé.

Kari Nadeau

Al­ladapt’s drug works sim­i­lar­ly to Aim­mune’s, but in­stead of just peanuts, it con­tains bits from nine al­ler­gen groups. The drug was de­vel­oped based on the work of its co-founder, Stan­ford al­ler­gist Kari Nadeau.

Dom­bkows­ki said the ba­sis of that all-in-one drug de­sign is that pa­tients who have one al­ler­gy are more like­ly to have oth­ers, and those mul­ti-al­ler­gic pa­tients are more like­ly to have se­vere re­ac­tions. And if a pa­tient were mul­ti-al­ler­gic, get­ting an in­di­vid­ual im­munother­a­py for each of their al­ler­gies would be com­pli­cat­ed, but ac­cord­ing to Nadeau’s re­search, pa­tients can be si­mul­ta­ne­ous­ly de­sen­si­tized to mul­ti­ple al­ler­gens, Dom­bkows­ki not­ed.

“The ap­proach where we have all of these anti­gens to­geth­er is kind of like a mul­ti­va­lent vac­cine — you’d love to get a shot that cov­ers all the vari­ants of a po­ten­tial re­ac­tion or in­fec­tion,” she said.

Al­ladapt’s can­di­date OIT, dubbed ​​ADP101, is cur­rent­ly in Phase I/II clin­i­cal tri­als, and the Men­lo Park, CA-based biotech an­nounced that it fin­ished en­rolling the tri­al at the start of this year. Al­ladapt al­so be­gan an open-la­bel ex­ten­sion tri­al in March.

No­tably, most OIT work, es­pe­cial­ly with peanuts, has been done with chil­dren, but Al­ladapt is run­ning tri­als for both chil­dren and adults. When asked about po­ten­tial low­er re­sponse rates in adults, Dom­bkows­ki said that from what she has seen from Nadeau’s re­search, adults tend to strug­gle more with ad­her­ing to the OIT, but there are adults who do re­spond to the treat­ment.

Al­ladapt’s lat­est fi­nanc­ing round was led by Ena­vate Sci­ences, and al­so in­clud­ed its found­ing in­vestor Gur­net Point Cap­i­tal, along­side Aller­Fund, Red Tree Ven­ture Cap­i­tal, WestRiv­er Group and, in­ter­est­ing­ly, No­var­tis.

Al­ladapt plans to read out its Phase I/II tri­al ear­ly next year and hopes to start a Phase III tri­al in 2024, Dom­bkows­ki said.

Up­dat­ed: Pfiz­er scoops up Glob­al Blood Ther­a­peu­tics and its sick­le cell ther­a­pies for $5.4B

Pfizer is dropping $5.4 billion to acquire Global Blood Therapeutics.

Just ahead of the weekend, word got out that Pfizer was close to clinching a $5 billion buyout — albeit with other potential buyers still at the table. The pharma giant, flush with cash from Covid-19 vaccine sales, apparently got out on top.

The deal immediately swells Pfizer’s previously tiny sickle cell disease portfolio from just a Phase I program to one with an approved drug, Oxbryta, plus a whole pipeline that, if all approved, the company believes could make for a $3 billion franchise at peak.

BREAK­ING: Math­ai Mam­men makes an abrupt ex­it as head of the big R&D group at J&J

In an after-the-bell shocker, J&J announced Monday evening that Mathai Mammen has abruptly exited J&J as head of its top-10 R&D group.

Recruited from Merck 5 years ago, where the soft spoken Mammen was being groomed as the successor to Roger Perlmutter, he had been one of the top-paid R&D chiefs in biopharma. His group spent $12 billion last year on drug development, putting it in the top 5 in the industry.

No­vavax shares shred­ded as Covid vac­cine sales fall more than 90% in Q2

Months after Novavax celebrated its first profitable quarter as a commercial company, the Gaithersburg, MD-based company is back in the red.

Sales for Novavax’s Covid-19 vaccine slipped to $55 million last quarter, down from $586 million in Q1, CEO Stanley Erck revealed on Monday after market close. The company’s stock $NVAX plummeted more than 32% in after-hours trading.

Upon kicking off the call with analysts and investors, Erck addressed the elephant in the room:

De­spite falling Covid-19 sales, BioN­Tech main­tains '22 sales guid­ance

While Pfizer raked in almost $28 billion last quarter, its Covid-19 vaccine partner BioNTech reported a rise in total dose orders but a drop in sales.

The German biotech reported over $3.2 billion in revenue in Q2 on Monday, down from more than $6.7 billion in Q1, in part due to falling Covid sales. While management said last quarter that they anticipated a Covid sales drop — CEO Uğur Şahin said at the time that “the pandemic situation is still very much uncertain” — Q2 sales still missed consensus by 14%.

With drug pric­ing al­most done, Con­gress looks to wrap up FDA user fee leg­is­la­tion

The Senate won’t return from its summer recess until Sept. 6, but when it does, it officially has 18 business days to finalize the reauthorization of the FDA user fee programs for the next 5 years, or else thousands of drug and biologics reviewers will be laid off and PDUFA dates will vanish in the interim.

FDA commissioner Rob Califf recently sent agency staff a memo explaining how, “Our latest estimates are that we have carryover for PDUFA [Prescription Drug User Fee Act], the user fee funding program that will run out of funding first, to cover only about 5 weeks into the next fiscal year.”

As­traZeneca and Dai­ichi Sankyo sprint to mar­ket af­ter FDA clears En­her­tu in just two weeks

Regulators didn’t keep AstraZeneca and Daiichi Sankyo waiting long at all for their latest Enhertu approval.

The partners pulled a win on Friday in HER2-low breast cancer patients who’ve already failed on chemotherapy, less than two weeks after its supplemental BLA was accepted. While this isn’t the FDA’s fastest approval — Bristol Myers Squibb won an OK for its blockbuster checkpoint inhibitor Opdivo in just five days back in March — it comes well ahead of Enhertu’s original Q4 PDUFA date.

Q&A: Astel­las' re­tir­ing head of de­vel­op­ment re­flects on gene ther­a­py deaths

For anyone who’s been following discussions about the safety alarms surrounding the adeno-associated viruses (AAV) commonly used to deliver gene therapy, Astellas should be a familiar name.

The Japanese pharma — which bought out Audentes Therapeutics near the end of 2019 and later built a gene therapy unit around the acquisition — rocked the field when it reported three patient deaths in a trial testing AT132, the lead program from Audentes designed to treat a rare muscle disease called X-linked myotubular myopathy (XLMTM).

When the company restarted the trial, it adjusted the dose and instituted a battery of other measures to try to prevent the same thing from happening again. But tragically, the first patient to receive the new regimen died just weeks after administration. The therapy remains under clinical hold, and just weeks ago, Astellas flagged another safety-related hold for a separate gene therapy candidate. In the process of investigating the deaths, the company has also taken flak about the way it disclosed information.

Big questions remain — questions that can have big implications about the future of AAV gene therapies.

Bernhardt Zeiher did not imagine any of it when he first joined Astellas as the therapeutic area leader in inflammation, immunology and infectious diseases. But his ascent to chief medical officer and head of development coincided almost exactly with Astellas’ big move into gene therapy, putting him often in the driver’s seat to grapple with the setbacks.

As Zeiher prepares to retire next month after a 12-year tenure — leaving the unfinished tasks to his successor, a seasoned cancer drug developer — he chatted with Endpoints News, in part, to discuss the effort to understand what happened, lessons learned and the criticism along the way.

The transcript has been lightly edited for length and clarity.

Endpoints: I want to also ask you a bit about the gene therapy efforts you’ve been working on. Astellas has really been at the forefront of discovering the safety concerns associated with AAV gene therapy. What’s that been like for you?

Zeiher: Well, I have to admit, it’s been a bit of a roller coaster. We acquired Audentes. Huge amount of enthusiasm. What we saw with AT132 — that was the lead program in XLMTM — was just remarkable efficacy. I mean, kids who went from being on ventilators, not able to eat for themselves, sit up, do things like that, to off ventilators, walking, you know, really — one investigator called it this Lazarus-like effect. It was just really dramatic efficacy. And then to have the safety events that occurred. So they actually occurred within that first year of the acquisition. So we had the three patient deaths. Me and my organization became very, very much involved. In fact, Ed Conner, who had been the chief medical officer, he left after some of the deaths, but I stepped in as the kind of acting chief medical officer, we had another chief medical officer who was involved, and then we had a fourth death, and I became acting again for a period of time.

Karuna's schiz­o­phre­nia drug pass­es a close­ly-watched PhI­II test, will head to FDA in mid-2023

An investigational pill that combines a former Eli Lilly CNS compound with an overactive bladder drug was better than placebo at reducing a scale of symptoms experienced by patients with schizophrenia in a Phase III trial.

Karuna Therapeutics’ drug passed the primary goal in EMERGENT-2, the Boston biotech said early Monday morning, alongside quarterly earnings. The study is the first of Karuna’s four Phase III clinical trials to read out in schizophrenia and will provide the backbone to the biotech’s first drug approval application, slated for mid-2023.
