Recruiting at 12 sites Phase 1, Phase 2 Hematologic Malignancies

Clinical trial for Hematologic Malignancies

Official title Study of SLS009 (Formerly GFH009) a Potent Highly Selective CDK9 Inhibitor in Patients With Hematologic Malignancies and High-Risk Newly Diagnosed AML

ClinicalTrials.gov ID: NCT04588922

What this study is testing

What is SLS009?

SLS009 is an investigational injectable medicine being studied as a potential treatment for certain blood cancers. SLS009 is designed to inhibit CDK9, a protein involved in cancer cell growth.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study looks at how safe and well patients tolerate SLS009 alone and with other drugs, and whether it can shrink tumors.
Who it's for
It is for adults with relapsed or refractory acute myeloid leukemia (AML) or lymphoma/CLL/SLL, and for some newly diagnosed AML patients who may not do well with standard treatments.
What's involved
Participants may receive SLS009 alone or with venetoclax and azacitidine, have regular blood tests, scans, and clinic visits to monitor safety and tumor response.
Time commitment
The study lasts several months, with multiple clinic visits and tests scheduled throughout the treatment period.
