Analyzing Phase 2 Trial Results for SLS009 (Tambiciclib) in Relapsed/Refractory Acute Myeloid Leukemia from SELLAS Life Sciences
Ticker(s): SLSA hematologist-oncologist specializing in AML treatment and development of targeted therapies for high-risk and relapsed/refractory hematologic malignancies, with expertise in CDK9 inhibition and venetoclax-based regimens.
The trial exceeded its target response rate of 20%, with a 44% ORR among AML-MR patients and 50% in M4/M5 subtypes at the 30 mg BIW dose. How significant are these response rates in the context of relapsed/refractory AML treatment?
Added By: slingshot_insightsMedian overall survival for patients refractory to venetoclax-based regimens reached 8.8 months, compared to a historical benchmark of 2.4 months. What does this survival improvement suggest about SLS009’s potential durability of response?
Added By: slingshot_insightsPatients with ASXL1 mutations showed a 50% ORR, indicating strong activity in high-risk molecular subgroups. How might these findings influence future patient selection and precision medicine strategies for AML?
Added By: slingshot_insightsSLS009 was combined with venetoclax and azacitidine without increased toxicity or dose-limiting events. How does this combination enhance anti-tumor activity, and could it redefine standard salvage therapy?
Added By: slingshot_insightsThe addition of SLS009 was well tolerated with no dose-limiting toxicities. How important is this safety profile when considering broader adoption or moving into first-line therapy?
Added By: slingshot_insightsThe FDA has recommended advancing SLS009 into a first-line AML trial for patients unlikely to benefit from standard aza/ven therapy or early non-responders. How could earlier intervention change patient outcomes compared to salvage settings?
Added By: slingshot_insightsSLS009 is described as potentially first and best-in-class with reduced toxicity and increased potency over other CDK9 inhibitors. What differentiates it mechanistically, and how might this translate clinically?
Added By: slingshot_insightsWith Phase 3 planning underway and enrollment expected in early 2026, what key endpoints and patient populations will be critical in determining SLS009’s path toward NDA submission and approval?
