Mer­ck­'s Keytru­da fails triple neg­a­tive breast can­cer piv­otal study

Months af­ter the FDA sanc­tioned the ap­proval of Roche’s run­ner up check­point in­hibitor Tecen­triq in com­bi­na­tion with Cel­gene’s Abrax­ane for treat­ment naive pa­tients with triple neg­a­tive breast can­cer, Mer­ck’s keynote PD-1 Keytru­da has stum­bled in a late-stage tri­al as the sec­ond or third line of de­fense against the rare, ag­gres­sive form of can­cer.

Pa­tients in the 622-pa­tient tri­al were ei­ther giv­en the block­buster treat­ment or chemother­a­py. The main goal of the study — over­all sur­vival — was not met, Mer­ck said, adding that de­tails will be dis­closed at a lat­er date.

The US drug­mak­er will con­tin­ue to test Keytru­da monother­a­py and in com­bi­na­tion with chemother­a­py in ear­li­er stages of the dif­fi­cult-to-treat dis­ease.

About 10-20% of all breast can­cers are triple-neg­a­tive breast can­cers (TNBCs), which char­ac­ter­is­ti­cal­ly has a high re­cur­rence rate with­in the first five years af­ter di­ag­no­sis. In TNBC pa­tients, the growth of the can­cer is not fu­eled by the hor­mones es­tro­gen and prog­es­terone, or by the HER2 pro­tein, mak­ing it hard to treat.

Roche’s Tecen­triq com­bi­na­tion with Abrax­ane was the first-ever im­munother­a­py to get ap­proval in the first­line TNBC set­ting. The ap­proval was key for the Swiss drug­mak­er that is third-in-line — be­hind Bris­tol-My­ers Squibb and Mer­ck — for the check­point in­hibitor Iron throne. The large drug­mak­er must get ahead of its ri­vals in cru­cial can­cer ar­eas if it wants to hold on to its po­si­tion, as As­traZeneca carves out a niche for its PD-L1 check­point Imfinzi in a sub­set of non-small cell lung can­cer pa­tients.

About 70% of breast can­cers di­ag­nosed in peo­ple with an in­her­it­ed BR­CA mu­ta­tion, par­tic­u­lar­ly BR­CA1, are di­ag­nosed with TNBC. PARP in­hibitors such as As­traZeneca’s Lyn­parza and Pfiz­er’s Talzen­na are al­ready ap­proved for germline BR­CA-mu­tat­ed breast can­cer, and are be­ing in­ves­ti­gat­ed in com­bi­na­tion with check­point in­hibitors for TNBC.

Mean­while, an­ti­body drug con­ju­gates are an­oth­er po­ten­tial treat­ment op­tion for TNBC un­der in­ves­ti­ga­tion.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

UP­DAT­ED: Boehringer nabs FDA's first in­ter­change­abil­i­ty des­ig­na­tion for its Hu­mi­ra com­peti­tor — but will it mat­ter?

The FDA late Friday awarded Boehringer Ingelheim the first interchangeability designation for its Humira biosimilar Cyltezo, meaning that when it launches in July 2023, pharmacists will be able to automatically substitute the Boehringer’s version for AbbVie’s mega-blockbuster without a doctor’s input.

The designation will likely give Boehringer, which first won approval for Cyltezo in 2017, the leg up on a crowded field of Humira competitors.

Bio­gen hit by ALS set­back with PhI­II fail­ure for tofersen — but fol­lows a fa­mil­iar strat­e­gy high­light­ing the pos­i­tive

Patients and analysts waiting to hear Sunday how Biogen’s SOD1-ALS drug tofersen fared in Phase III didn’t have to wait long for the top-line result they were all waiting for. The drug failed the primary endpoint on significantly improving the functional and neurologic decline of patients over 28 weeks as well as the extension period for continued observation.

In fact, there was very little difference in response.

FDA OKs an in­haled ver­sion of smok­ing ces­sa­tion drug Chan­tix — for a com­mon eye dis­ease

Oyster Point Pharma now has its first FDA-approved product — Tyrvaya. And the biotech has taken a unique route to get there by using an old drug with a storied past.

The New Jersey biotech announced this morning that the FDA has approved their nasal spray product for dry eye disease on Friday — the first nasal spray to be approved for the disease. The product’s active ingredient is 0.03 mg of varenicline, also known as smoking cessation aid Chantix.

Es­pe­ri­on gets out the bud­get ax, chop­ping 170 staffers as its big drug launch sput­ters

Esperion’s executive team spent years insisting that they had found the sweet spot in the market for their cholesterol drug. But that strategy has soured badly, and after struggling to sell its heart disease pill for more than a year, the biotech says it will cut about 40% of its staff over the next few weeks.

The layoffs will take place across the board, from sales and marketing to R&D, CEO Sheldon Koenig told Endpoints News on Monday. While the chief executive declined to elaborate on how many employees will be affected, an SEC filing stated that approximately 170 staffers are on the chopping block.

Two drug­mak­ers hit with PDU­FA date de­lays from FDA amid back­log of in­spec­tions

As the FDA is weighed down with more and more pandemic responsibilities, the agency is beginning to miss PDUFA dates with more frequency too. Two different companies on Monday said they received notices that the FDA has not completed their drug reviews on time.

The review of an NDA for Avadel Pharmaceuticals’ candidate treatment for narcolepsy is not coming this month, the company said, and the review of UCB’s BLA for bimekizumab, used to treat moderate to severe plaque psoriasis, will miss its target date as well.

Ver­tex gets much-need­ed win with ‘ex­tra­or­di­nary’ first pa­tient re­sults on po­ten­tial di­a­betes cure

Vertex said Monday that the first patient dosed with its cell therapy for type 1 diabetes saw their need for insulin injections vanish almost entirely, a key early step in the decades-long effort to develop a curative treatment for the chronic disease.

The patient, who had suffered five potentially life-threatening hypoglycemic — or low blood sugar — episodes in the year before the therapy, was injected with synthetic insulin-producing cells. After 90 days, the patient’s new cells produced insulin steadily and ramped up their insulin production after a meal like normal cells do, as measured by a standard biomarker for insulin production.

No­var­tis de­vel­op­ment chief John Tsai: 'We go deep in the new plat­form­s'

During our recent European Biopharma Summit, I talked with Novartis development chief John Tsai about his experiences over the 3-plus years he’s been at the pharma giant. You can read the transcript below or listen to the exchange in the link above.

John Carroll: I followed your career for quite some time. You’ve had more than 20 years in big pharma R&D and you’ve obviously seen quite a lot. I really was curious about what it was like for you three and a half years ago when you took over as R&D chief at Novartis. Obviously a big move, a lot of changes. You went to work for the former R&D chief of Novartis, Vas Narasimhan, who had his own track record there. So what was the biggest adjustment when you went into this position?
