A Biomarker-Directed Phase 2 Trial of SY-1425, a Selective Retinoic Acid Receptor Alpha Agonist, in Adult Patients with Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS)
You are being asked to take part in this study because you have acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) and the standard drugs to treat the disease are no longer effective, treatment was not effective for your type of disease, or the standard treatments are not suitable for you. The goal of this clinical research study is to learn if an investigational drug SY-1425 (sometimes known as tamibarotene), when given alone or in combination with azacitidine (Vidaza), can help to control AML or MDS in patients who have certain biomarkers. Biomarkers are found in the blood/tissue and may be related to your reaction to SY-1425. Researchers want to learn if patients who have the biomarkers being studied will respond to SY-1425 better than patients who do not have them. The safety of this drug will also be studied.
Disease Group: Malignant neoplasms stated as primary lymphoid haematopoietic
Treatment Agent: Tamibarotene
Treatment Location: Both at MDACC & and Other Sites
Sponsor: Syros Pharmaceuticals, Inc.
Primary The primary objective is: Characterize the clinical activity of SY-1425 by the overall response rate (ORR) in patients in Arms 1, 2A and 2B, and by the transfusion independence rate (TIR) in patients in Arm 3 Secondary The secondary objectives are: Characterize the clinical activity of SY-1425 in patients positive for the RARA super-enhancer associated biomarker by the ORR in Arms 1, 2A, 2B and by TIR in Arm 3 Characterize the clinical activity of SY-1425 in patients positive for the IRF8 biomarker and negative for the RARA super-enhancer associated biomarker by the ORR in Arms 1, 2A, 2B and by TIR in Arm 3 Characterize the clinical activity by patients in Arms 1, 2A, 2B and 3, based on event-free survival (EFS), relapse-free survival (RFS), duration of response (DOR), overall survival (OS), hematologic improvement (HI) For all patients, evaluate the requirement for supportive measures secondary to cytopenias Characterize the safety and tolerability of SY-1425 Characterize the PK of SY-1425 after single and multiple doses Exploratory The exploratory objectives are: Assess factors associated with the ORR, including but not limited to arm and diagnosis, RARA super-enhancer associated biomarker and/or IRF8 biomarker status, dehydrogenase/reductase (SDR family) member 3 (DHRS3) induction, myeloid differentiation, and other potential predictors of success including genotype and mutation status Evaluate changes in health related quality of life (HRQOL). Establish pharmacokinetic (PK)/PD relationships based on PD markers in leukemic cells from repeat peripheral blood samples. Characterize the relationship between SY-1425 activity and baseline tumor biomarker levels (RARa mRNA or IRF8 mRNA) Explore the potential role of additional genes alterations (e.g. expression or mutation) in sensitivity and/or resistance to SY-1425 using multiplex platform such as ChipSeq analysis.
