Faron Pharmaceuticals Ltd. provided further data from patients treated during the Phase 1 part of the ongoing BEXMAB trial that has moved into Phase 2 for higher-risk (HR) myelodysplastic syndrome (MDS) patients failed on previous hypomethylating agent (HMA). Previous BEXMAB study results indicated a high overall response rate (ORR) of 5/5 amongst HR HMA- failed MDS patients, for whom there is no approved treatment. The majority of the initial Phase 1 patients have now been on treatment with bexmarilimab together with azacitidine for more than six months, and only one patient has been lost due to transformation of their HR MDS into acute myeloid leukemia (AML).

Out of these initial 5 patients, 4 remain alive after eight months. For the 5 frontline HR MDS patients with 100% ORR previously reported at the American Society of Hematology (ASH) Annual Meeting last year, mOS has also not yet been reached. For the r/r AML patient cohort reported at ASH, which is bigger in size (n= 18) and more mature in follow-up (median follow-up six months), the mOS is currently estimated to be over 8 months (still subject to change as some patients are still ongoing).
