Gene therapy developer Beam Therapeutics Inc. has acquired drug delivery specialist Guide Therapeutics Inc. in a deal valued at up to $440 million, adding yet another piece of the integrated platform CEO John Evans told BioWorld the company is striving to build. Guide's lipid nanoparticle (LNP) screening technology could help medicines developed by Beam and its partners reach new targets beyond the liver, an increasingly important endeavor for gene therapy developers like Beam, seeking to maximize the breadth of their growing portfolios. Terms of the deal included $120 million up front, plus up to $320 million in stock-based technology and product success milestone payments. Shares in Beam (NASDAQ:BEAM) fell 12.6% to $96.48 on Feb. 23.
Hopes that a second clinical win for Otonomy Inc.'s phase III Meniere's disease candidate, Otividex, might set the stage for a third-quarter registration of the drug in the U.S. have been dashed, sending company shares (NASDAQ:OTIC) down 44.3% to $3 on Feb. 22. For the intent-to-treat (ITT) population, the trial missed its primary endpoint, the count of definitive vertigo days in month three for the sustained-exposure dexamethasone therapy vs. placebo. The trial also failed to achieve statistical significance for a per-protocol analysis. It was déjà vu for the company, which suffered a harsh reaction to an earlier setback for the program from which its stock has yet to recover, years later.
News of Vaccinex Inc. signing two multitarget deals with undisclosed "prominent pharmaceutical companies" sent company shares (NASDAQ:VCNX) up 70% to $4.88 on Feb. 19, even as financial terms of the deal went undisclosed.

Just months after a modest IPO, shares of Immunome Inc. (NASDAQ:IMNM) climbed 75.6% on Feb. 18, closing at $39.01.

Shares of Bluebird Bio Inc. (NASDAQ:BLUE) fell 37.8% to $28.44 on Feb. 16 as the company temporarily suspended two trials of its experimental gene therapy for sickle cell disease, Lentiglobin (BB-1111), while investigating one unexpected case of acute myeloid leukemia (AML) and another of myelodysplastic syndrome among participants in a phase I/II study of the candidate, called HGB-206. A second patient experienced MDS in 2018.
Sagimet Biosciences Inc., a company developing an oral fatty acid synthase (FASN) inhibitor for the potential treatment of nonalcoholic steatohepatitis, has raised $80 million in a crossover financing led by an undisclosed public equity health care investment fund.
Nearly five months after its tau-directed antibody, semorinemab, failed to demonstrate efficacy in a phase II trial in Alzheimer’s disease, AC Immune SA is back with positive data on a different approach with its anti-phospho-tau vaccine candidate, ACI-35.030.
Ensoma Inc., a gene therapy startup working to drastically simplify the production and delivery of genomic medicines, announced itself Feb. 11 with a $70 million series A financing plus a strategic collaboration with Takeda Pharmaceutical Co. Ltd., which licensed vectors from the company for up to five rare disease targets in a deal that could deliver as much as $1.25 billion in potential payouts. Ensoma's co-founder and seed investor, 5AM Ventures, led the financing. Takeda took a $10 million equity stake as part of the round.
New interim phase II data in advanced non-small-cell lung cancer (NSCLC) has shown that a combination of Heat Biologics Inc.'s cell therapy candidate, HS-110 (viagenpumatucel-L), and Bristol Myers Squibb Co.'s Opdivo (nivolumab) helped extend overall survival for both checkpoint inhibitor-naïve patients and those who had been treated with a checkpoint inhibitor but whose disease had later progressed.
