Post-PhI­II im­plo­sion, Celldex buys on­col­o­gy drug de­vel­op­er Koll­tan in $235M deal

Ger­ald McMa­hon, CEO, Koll­tan

Eight months af­ter watch­ing ex­pec­ta­tions for its can­cer vac­cine Rin­te­ga (rindopepimut) im­plode in a failed Phase III glioblas­toma study, Celldex Ther­a­peu­tics $CLDX is do­ing some pipeline re­con­struc­tion, buy­ing out Koll­tan Phar­ma­ceu­ti­cals in an all-stock deal.

Koll­tan in­vestors get $62.5 mil­lion in Celldex stock up front, along with $172.5 mil­lion for a slate of mile­stones in the deal. In ex­change, Celldex gets a pipeline of on­col­o­gy pro­grams con­sist­ing of an­ti­body-based drugs tar­get­ing re­cep­tor ty­ro­sine ki­nas­es, or RTKs.

“Koll­tan’s pro­grams tar­get­ing KIT, ErbB3 and TAM re­cep­tors po­ten­tial­ly ad­dress ma­jor chal­lenges sur­round­ing tu­mor re­sis­tance mech­a­nisms in can­cer bi­ol­o­gy,” said Ger­ald McMa­hon, the CEO at Koll­tan, who went on to praise their back­ground at Medarex work­ing on an­ti­body de­vel­op­ment.

Koll­tan tried, and failed, to push through an $86 mil­lion IPO back in the go-go days of 2014.

Their port­fo­lio in­cludes:

  • KTN0158 — a hu­man­ized mon­o­clon­al an­ti­body that is a po­tent in­hibitor of KIT ac­ti­va­tion in tu­mor cells and mast cells; cur­rent­ly in a Phase 1 dose es­ca­la­tion study in re­frac­to­ry gas­troin­testi­nal stro­mal tu­mors.
  • KTN3379 — a hu­man mon­o­clon­al an­ti­body de­signed to block the ac­tiv­i­ty of ErbB3 (HER3); clin­i­cal ac­tiv­i­ty in­clud­ing mean­ing­ful re­spons­es and sta­ble dis­ease has been ob­served in a Phase 1b study in ce­tux­imab (Er­bitux) re­frac­to­ry pa­tients in head and neck squa­mous cell car­ci­no­ma and in BRAF-mu­tant non-small cell lung can­cer.
  • A TAM pro­gram, which in­cludes a “broad an­ti­body dis­cov­ery ef­fort un­der­way to gen­er­ate an­ti­bod­ies that mod­u­late the TAM fam­i­ly of RTKs, com­prised of Ty­ro3, AXL and MerTK.”

Health­care Dis­par­i­ties and Sick­le Cell Dis­ease

In the complicated U.S. healthcare system, navigating a serious illness such as cancer or heart disease can be remarkably challenging for patients and caregivers. When that illness is classified as a rare disease, those challenges can become even more acute. And when that rare disease occurs in a population that experiences health disparities, such as people with sickle cell disease (SCD) who are primarily Black and Latino, challenges can become almost insurmountable.

Jacob Van Naarden (Eli Lilly)

Ex­clu­sives: Eli Lil­ly out to crash the megablock­buster PD-(L)1 par­ty with 'dis­rup­tive' pric­ing; re­veals can­cer biotech buy­out

It’s taken 7 years, but Eli Lilly is promising to finally start hammering the small and affluent PD-(L)1 club with a “disruptive” pricing strategy for their checkpoint therapy allied with China’s Innovent.

Lilly in-licensed global rights to sintilimab a year ago, building on the China alliance they have with Innovent. That cost the pharma giant $200 million in cash upfront, which they plan to capitalize on now with a long-awaited plan to bust up the high-price market in lung cancer and other cancers that have created a market worth tens of billions of dollars.

The End­points 11: They've got mad mon­ey and huge am­bi­tions. It's time to go big or go home

These days, selecting a group of private biotechs for the Endpoints 11 spotlight begins with a sprint to get ahead of IPOs and the M&A teams at Big Pharma. I’ve had a couple of face plants earlier this year, watching some of the biotechs on my short list choose a quick leap onto Nasdaq or into the arms of a buyer.

Vividion, you would have been a great pick for the Endpoints 11. I’m sorry I missed you.

Dave Lennon, former president of Novartis Gene Therapies

So what hap­pened with No­var­tis Gene Ther­a­pies? Here's your an­swer

Over the last couple of days it’s become clear that the gene therapy division at Novartis has quietly undergone a major reorganization. We learned on Monday that Dave Lennon, who had pursued a high-profile role as president of the unit with 1,500 people, had left the pharma giant to take over as CEO of a startup.

Like a lot of the majors, Novartis is an open highway for head hunters, or anyone looking to staff a startup. So that was news but not completely unexpected.

FDA+ roundup: Bs­U­FA III ready for show­time, court tells FDA to re-work com­pound­ing plan, new guid­ance up­dates and more

The FDA has now spelled out what exactly will be included in the third iteration of Biosimilar User Fee Act (BsUFA) from 2023 through 2027, which similarly to the prescription drug deal, sets fees that industry has to pay for submitting applications, in exchange for firm timelines that the agency must meet.

This latest deal includes several sweeteners for the biosimilar industry, which has yet to make great strides in the US market, with shorter review timelines for safety labeling updates and updates to add or remove an indication that does not contain efficacy data.

Who are the women su­per­charg­ing bio­phar­ma R&D? Nom­i­nate them for this year's spe­cial re­port

The biotech industry has faced repeated calls to diversify its workforce — and in the last year, those calls got a lot louder. Though women account for just under half of all biotech employees around the world, they occupy very few places in C-suites, and even fewer make it to the helm.

Some companies are listening, according to a recent BIO survey which showed that this year’s companies were 2.5 times more likely to have a diversity and inclusion program compared to last year’s sample. But we still have a long way to go. Women represent just 31% of biotech executives, BIO reported. And those numbers are even more stark for women of color.

With world still in sore need of dos­es, Clover says its Covid-19 vac­cine is 67% ef­fec­tive in Phase III

With concerns about the Delta variant rising and much of the world still in desperate need of vaccine doses, a Chinese biotech announced Wednesday that a new shot has shown positive results in a large trial against Covid-19, including new variants.

Clover Biopharmaceuticals announced Wednesday that its vaccine candidate showed 79% efficacy against the Delta variant in a Phase II/III trial dubbed Spectra, and 67% effective against Covid-19 overall.

Lux­tur­na in­ven­tor Jean Ben­nett starts a new gene ther­a­py com­pa­ny to tack­le rare dis­eases left be­hind by phar­ma, VCs

A few years ago Jean Bennett found herself in a surprising place for a woman who invented the first gene therapy ever approved in the United States: No one, it seemed, wanted her work.

Bennett, who designed and co-developed Luxturna, approved in 2018 for a rare form of blindness, had kept building new gene therapies for eye diseases at her University of Pennsylvania lab. But although the results in animals looked promising, pharma companies and investors kept turning down the pedigreed ophthalmology professor.

Hexa­gon Bio rais­es $61M to con­tin­ue ef­forts to turn fun­gi in­to drugs

A year after raising a $47 million launch round, the fungi-loving drug hunters at Hexagon Bio have more than doubled their coffers.

Hexagon announced today that it raised another $61 million for its efforts to design cancer and infectious disease drugs based on insights mined from the DNA in millions of species of fungi. The new financing brings Hexagon’s committed funding to over $108 million.
