Unexpected behavior of neutrophils unveiled by researchers at Stanford University could lead to a new type of immunotherapy to treat cancer. Although various studies have suggested that these cells are harmful due to their immunosuppressive characteristics, the scientists saw in them an opportunity to redirect them and eliminate tumors.
Iovance Biotherapeutics Inc.’s faith in tumor-infiltrating lymphocyte (TIL) therapy lifileucel was further proven by the Jan. 23 acquisition of worldwide rights from Clinigen Ltd. to Proleukin (aldesleukin), an IL-2 product used to promote T-cell activity after infusion of TILs. Terms call for San Carlos, Calif.-based Iovance to pay Clinigen, of Burton Upon Kent, U.K., £166.7 million (US$$206.1 million) right away and a £41.7 million milestone payment upon first approval of lifileucel in advanced melanoma, plus double-digit global royalties for Clinigen.
While immune checkpoint inhibitors have revolutionized oncology, still only 20-30% of patients respond to PD-1/PD-L1 antibody monotherapy. This can be due to a failure of T cells to recognize “cold” tumors (low T-cell infiltrates).
During metastasis, the mechanical properties of the nucleus make translocation of this organelle the rate-limiting step during constrained migration, and these properties are regulated through interactions between the cytoskeleton, integral nuclear envelope (NE) proteins, the nuclear lamina and chromatin.
Aptevo Therapeutics Inc. has filed a provisional patent with the U.S. Patent and Trademark Office (USPTO) pertaining to an anti-PD-L1 x anti-CD40 bispecific antibody, APVO-711, with the potential to treat a range of solid malignancies such as head and neck squamous cell carcinoma, melanoma and carcinomas of the lung, gastrointestinal tract and colon.
The California Institute for Regenerative Medicine (CIRM) has awarded Calidi Biotherapeutics Inc. a US$3.1 million grant to support continued development of the company's Supernova-1 (SNV-1) preclinical program through IND application. The grant was awarded to Calidi to support IND-enabling studies, finalize manufacturing and the completion of Calidi's IND application for the SNV-1 program.
