Median general survival of all sufferers within the cohort was 8.8 months, whereas these with AML-myelodysplasia-related modified had a median general survival of 8.9 months.
SLS009 (tambiciclib) has been discovered to be related to an enchancment in survival amongst sufferers with relapsed/refractory acute myeloid leukemia (r/r AML).
The findings had been shared in a information launch from late-stage scientific biopharmaceutical firm SELLAS Life Sciences Group, Inc., saying knowledge from cohort 3 of an ongoing part 2 trial of SLS009. The remedy was described as a extremely selective CDK9 inhibitor.
The median general survival of all sufferers in cohort 3 was 8.8 months, and the median general survival in sufferers with AML-myelodysplasia-related modifications (AML-MRC) was 8.9 months.
“The exceptional outcomes from cohort 3 of the continued part 2 trial reinforce the potential of SLS009 to remodel outcomes for these closely pretreated [patients with AML],” mentioned Dr. Angelos Stergiou, president and CEO of SELLAS, within the information launch. “Not solely have we noticed unprecedented survival advantages, however the excessive response charge underscores the remedy’s efficacy profile.”
The info, as Stergiou outlined, present that sufferers whose illness was relapsed or refractory to Venclexta (venetoclax)-based regimens sufferers and who acquired 30 milligrams twice every week achieved a median general survival of 8.8 months, surpassing the historic benchmark of two.5 months.
Moreover, the remedy demonstrated a 67% goal response charge in sufferers with AML-MRC and 46% in all evaluable sufferers.
“With responses seen throughout totally different genetic mutations, this strategy may very well be transformational for a lot of underserved sufferers. We’re persevering with to discover SLS009’s potential in growth cohorts to additional validate its potential to handle essential unmet medical wants,” Stergiou mentioned.
Moreover, three of 4 sufferers with myelomonocytic AML responded to remedy. 4 of six sufferers with mutations ASXL1 responded, three of 5 sufferers with RUNX1 mutations responded and one in every of three sufferers with TP53 responded, in addition to one in every of three sufferers with antagonistic karyotypes.
Within the trial, 14 sufferers with relapsed and refractory AML whose illness had beforehand failed on Venclexta-based therapies had been enrolled and acquired remedy with SLS009 and Venclexta/azacitidine in cohort 3. Ten of 14 sufferers had AML-MRC.
The median age of sufferers was 71, the median variety of prior failed therapies was one, 13 of 14 sufferers had been evaluable for efficacy and all sufferers had antagonistic danger cytogenetics.
SLS009, the information launch famous, was discovered to be well-tolerated, with no new security alerts noticed. The part 2 trial continues in growth cohorts 4 and 5, amongst sufferers with AML-myelodysplasia-related modifications (AML-MRC) with ASXL1 mutation and mutations and cytogenic modifications aside from ASXL1, respectively.

The trial is presently recruiting and is being held at 21 websites throughout the US and China, in line with its itemizing on clinicaltrials.gov. The trial has an estimated main completion date of June 30, 2025, and an estimated research completion date of Dec. 31, 2025, in line with the itemizing.
The part 2 trial, in line with the information launch, is an open-label, single-arm research evaluating the protection, tolerability and efficacy of SLS009 together with Venclexta and azacitidine at 45 and 60 milligram dose ranges, with the 60 milligram dose being administered both as soon as every week or as 30 milligrams twice every week.
In 2023, the U.S. Meals and Drug Administration granted Quick Observe designation to SLS009 for the remedy of sufferers with relapsed or refractory peripheral T-cell lymphomas.
