Cancer cell-based therapies coming into 'important' year for R&D, say SVB analysts
Despite investor doubt in allogeneic cell therapy, 2023 will be an “important” year for both autologous and allogeneic immune-cell-based therapies in multiple myeloma and non-Hodgkin’s lymphoma, SVB analysts predict.
With drug candidates like mosunetuzumab, glofitamab and epcoritamab making their way through clinical trials, SVB Securities analysts are predicting the commercialization of bispecific CD3 T-cell engagers will begin to be a part of treatment paradigms as these drugs get approved.
“We expect maturation of these markets will be multi-year journeys, impacted by (lack of) necessary infrastructure and training in the community setting to deliver TCEs, slow release of manufacturing constraints for auto CAR-T, as well as ongoing data disclosures in earlier lines, from combinations, and with class sequencing,” SVB analysts wrote in a lengthy report released Tuesday.
Analysts also had a critique for the American Society for Hematology (ASH) meeting where there was undue investor pessimism toward allogeneic therapies: “For us, this is overdone, with much of the allogeneic criticism premature, given allogeneic cell therapies are in the nascent stages of clinical development.”
Allogeneic T-cell therapy took a big step forward in Europe last month with the approval of the first one on the continent. The European Commission signed off on Ebvallo, made by Atara Biotherapeutics, for patients with post-transplant lymphoproliferative disease who are positive for Epstein-Barr virus. Other clinical trials with Ebvallo are ongoing.
Also last month, Beam Therapeutics got the go-ahead from the FDA to continue with human testing for a base-edited, off-the-shelf CAR-T therapy in a certain type of leukemia. Beam can now investigate its candidate BEAM-201 as a potential treatment for patients with relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL)/T-cell lymphoblastic lymphoma (T-LL). Beam is one of several biotechs working on an allogeneic CAR-T therapy, which requires donor cells rather than a patient’s own cells.
The SVB analysts also took a look at what’s coming for non-Hodgkin’s lymphoma treatment, including mosunetuzumab, which just earned an FDA accelerated approval. Analysts are also keeping tabs on other FDA actions yet to come: the first potential bispecific engager approvals for 3L+ large B-cell lymphoma like epcoritamab, which was granted priority review, and an anticipated July 2023 PDUFA date for Roche’s glofitamab.
“We also anticipate numerous Ph 1/2 updates from the bispecifics and the autologous and allogeneic cell therapies throughout the year,” the analysis reads. “Of these, initial Ph 1 data from DTIL’s (Not Rated) second-generation allogeneic CD19-CAR-T candidate, PBCAR19B, in 1Q23 could prove a particularly important catalyst for all allo cell therapy developers, given that the program incorporates multiple immune evasion, or “stealth”, modalities.”
