This Phase 1a/1b study is an open label, multicenter trial in subjects with higher-risk (i.e., intermediate, high or very high risk by IPSS-R) MDS or AML. The study is designed to evaluate the safety, PK, pharmacodynamic effects, and preliminary anti tumor activity of SL-172154 monotherapy and SL-1712154 administered with either Azacitidine or Azacitidine and Venetoclax. Subjects will receive SL-172154 as monotherapy or administered with Azacitidine with or without Venetoclax until documented disease progression, unacceptable toxicity or intolerance, withdrawal of consent, or the subject meets other criteria for discontinuation (whichever occurs first).
SL03-Old Hundred(OHD)-104 is designed as a Phase 1a/1b open label, trial to evaluate the safety, pharmacokinetics (PK), pharmacodynamic (PD), and preliminary efficacy of SL-172154 monotherapy as well as in combination with azacitidine or in combination with Azacitidine and Venetoclax.
