Allogene is making a durability case for its most advanced CAR T cell program amid rising doubts that off-the-shelf cancer cell therapies will be able to generate the long-term, curative effects seen with autologous products.


Allogene hints at allogeneic CAR T durability with ALLO-510A data

During an R&D presentation from Allogene Therapeutics, the company reported updated data from ALLO-501A, an autologous CAR T cell therapy targeting CD19, demonstrating complete responses lasting more than two years in patients with large B cell lymphoma. At the latest data cut, nine of the 10 patients who were in complete response one year ago remained in CR. Two patients had durable CRs lasting more than two years, and a third was approaching the 24-month evaluation. At 29% across all patients treated (14/48), the complete response rate is lower than those of autologous CAR T cells, but patients who continue responding for six months appear likely to achieve long-term effects.

Sana Biotechnology announced layoffs and pipeline prioritization

Sana Biotechnology announced a portfolio prioritization and headcount reduction of about 15% to focus on programs near the clinic and maintain cash runway into 2025. The company said it expected to submit five INDs by YE24, but will discontinue internal investment in SC187, its cardiomyocytes for heart failure program. Planned INDs include one in 2022 for SC291, its CD19-targeted allogeneic CAR T, as well as two in 2023 for SG295 and SC263, the company’s in vivo CAR T with CD8-targeted fusogen delivery of a CD19-targeted CAR and CD22-targeted allogeneic CAR T, respectively. Sana reported $485.8 million cash on Sept. 30 and a nine-month operating loss of $190.8 million.
