Two deals for antibody-drug conjugates inked since May between Merck & Co. Inc. and Sichuan Kelun-Biotech Pharmaceutical Co. Ltd. have blossomed eight months later into the year’s biggest agreement, one that could bring Kelun-Biotech up to $9.3 billion in development, regulatory and sales milestones.
Biopharma just wouldn’t be biopharma without continuing innovation. Even in a year rife with economic and regulatory turmoil, the industry still achieved major advancements set to change the health care landscape going forward. Standouts for 2022 include cell therapy and gene editing approaches making significant gains, while industry celebrated a new checkpoint inhibitor added to the oncology armamentarium.
While new data from Arcus Biosciences Inc. and Gilead Sciences Inc. didn't do much to calm an unsteady development corridor, researcher, developers and analysts still hold out hope for the TIGIT pathway. The Arcus-Gilead randomized phase II study combining anti-TIGIT domvanalimab and anti-PD1 antibodies for treating first-line, metastatic non-small-cell lung cancer produced positive results, including improvements in median progression-free survival (PFS) and six-month landmark PFS rates vs. monotherapy. But a hefty dent in Arcus' shares provide a reminder of TIGIT’s fragility as a field, and a reminder of the phase III failure in May for Roche Holding AG unit Genentech Inc.'s anti-TIGIT immunotherapy tiragolumab, which dragged down the share value of several other class entrants. Arcus stock (NASDAQ:RCUS) dipped deeply on Dec. 20 on the new data’s release, but rallied on Dec. 21 by closing 7.5% upward at $22.15 each.
After posting positive top-line data in August from its phase III ENHANCE-2 study of ensifentrine for treating chronic obstructive pulmonary disease (COPD), Verona Pharma plc now has positive results from the companion phase III study. The ENHANCE-1 trial of ensifentrine as a COPD maintenance treatment hit its primary and key secondary endpoints, prompting the company to say it plans to submit an NDA for the treatment to the U.S. FDA sometime in the first half of 2023.
Ferring Pharmaceuticals A/S has notched another U.S. FDA approval, this time for a bladder cancer treatment, Adstiladrin (nadofaragene firadenovec). The non-replicating adenovirus vector-based gene therapy’s approval comes only weeks after the FDA’s Nov. 30 approval of the privately held company’s Rebyota (fecal microbiota, live), the first fecal microbiota treatment in the U.S. Adstiladrin is another landmark, as the first FDA-approved gene therapy to treat high-risk, non-muscle-invasive bladder cancer. Saint-Prex, Switzerland-based Ferring said it anticipates the product becoming commercially available in the U.S. in the second half of 2023.
Bryostatin-1 has failed another Alzheimer’s disease (AD) study. Synaptogenix Inc. released top-line data showing the protein kinase C activator missed the primary endpoint in the company’s phase II study in treating advanced AD.
When potentially dangerous high liver enzymes showed up in two asymptomatic participants during Third Harmonic Bio Inc.’s ongoing phase Ib study of the KIT inhibitor THB-001, the company decided to discontinue the clinical trial.
A preliminary assessment of Avidity Biosciences Inc.’s phase I/II study of AOC-1001 in myotonic dystrophy type 1 (DM1) showed the first-ever targeted delivery of RNA into muscle, an area previously untreatable with existing RNA therapeutics. Sarah Boyce, Avidity’s CEO, said in a Dec. 14 call that the antibody oligonucleotide conjugate’s data were unprecedented in the RNA space and in myotonic dystrophy type 1 (DM1), labeling it a “revolutionary advancement.”
Wave Life Sciences Ltd. is partnering again. The company is getting $170 million up front – $120 million in cash and a $50 million equity investment – in a new partnership with GSK plc to advance oligonucleotides in unnamed targets. The agreement, which has a four-year research term, allows for GSK to advance up to eight programs using Wave Life’s platform and for Wave Life to advance three, or more if GSK approves, of its own collaboration programs.
The successful suitor for Horizon Therapeutics plc has been revealed as Amgen Inc., which will buy the Dublin-based company for $27.8 billion in cash in what is by far the year’s biggest acquisition. The deal brings successful biologics into Amgen’s portfolio that include Tepezza (teprotumumab), a monoclonal antibody targeting insulin-like growth factor 1 for treating thyroid eye disease, Krystexxa (pegloticase), a pegylated uricase enzyme for treating chronic refractory gout, and Uplizna (inebilizumab), a monoclonal antibody targeting insulin-like growth factor 1 for treating thyroid eye disease.
