Pharma-biotech pairings continued apace in the antibody-drug conjugate (ADC) space, with 2023 capped by Legochem Biosciences Inc. signing a $1.7 billion licensure deal with Johnson & Johnson arm Janssen Biotech Inc. for the former’s Trop2-directed compound, the second-biggest Korean technology transfer agreement.

Critically shortened telomeres are known to be a key limiting factor in successful CAR T-cell immunotherapy, with cells from older patients tending to have shorter telomeres with reduced dividing capacity. As such, these cells are unable to fully eliminate malignancies and provide durable and persistent protection against cancer. So, what if you could lengthen these DNA-protein structures found at the end of chromosomes during the ex-vivo manufacturing of CAR T cells, i.e., before they are put back into the body, so increasing their potency against disease? Newly-launched firm Telos Biotech – a subsidiary company of Cambrian Bio – believes you can, with its patent-protected recombinant protein, Telovance, promising to shake up the cell therapy field.

With the biggest biosimilar launch in the U.S. just days away, Humira’s (adalimumab) record-breaking ride is quickly slowing down, but the Abbvie Inc. mega-blockbuster immunology drug is nowhere near the end of its road. Meanwhile, the U.S. journey is just beginning for the eight adalimumab biosimilars that could come to market as early as July 1 through licensing agreements with Abbvie. Besides revving their engines against Humira, the new launches will be looking to overtake Amgen Inc.’s biosimilar, Amjevita, which got a five-month headstart in the U.S., thanks to the first-mover status Amgen earned for being the first to sign a licensing agreement with Abbvie.

A slew of biosimilar versions of TNF-alpha inhibitor adalimumab will finally arrive on the U.S. market in 2023, almost seven years after the first such molecule, Amgen Inc.’s Amjevita (adalimumab-atto) gained U.S. FDA approval. Amgen commercially launched its product on Jan. 31. Seven more are lined up for launch over the summer, while two more are undergoing regulatory review. Their long-anticipated arrival will mark the beginning of the end for one of the most lucrative franchises in the history of the pharmaceutical industry. It represents, according to Cardinal Health Inc.’s newly published 2023 Biosimilars Report, “the largest loss of exclusivity event, perhaps ever in the U.S.”

Apogee Therapeutics Inc. emerged from stealth with $169 million in financing and a pipeline of four preclinical antibody development programs that take aim at major immunological and inflammatory disorders.

Human Immunology Biosciences (HI-Bio) Inc., a company developing targeted therapies for severe immune-mediated diseases, has secured $120 million in financing. Its initial pipeline is built around two clinical-stage immunology assets in-licensed from Morphosys AG in June 2022. The funds will help the company move through key inflection points over the coming years, in both in its ongoing clinical and discovery programs, where it's currently focused on the role of mast cells as a cellular driver of disease.

Odyssey Therapeutics Inc. closed a hefty $168 million series B round to progress multiple small-molecule and protein-based drug discovery and development programs in autoimmune disease and cancer.

A new vaccine that uses the native-like HIV-1 envelope (Env) trimer CH505 and a Toll-like receptor (TLR) 7/8 agonist adjuvant, successfully evaluated in macaques, generated potent polyclonal neutralizing antibodies (nAbs) and a high protection against the infection of the homologous simian-human immunodeficiency virus (SHIV).
