Safety, Tolerability and Pharmacokinetics Study of KPG-818 in Hematological Malignancies Subjects KPG-818

What's the purpose of this trial?

This is a Phase 1 study to evaluate the safety, pharmacokinetics(PK), and preliminary clinical activity of KPG-818 as a single agent in adult subjects with selected hematological malignancies, including multiple myeloma (MM), mantle cell lymphoma (MCL), follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), indolent lymphoma, adult T-cell leukemia-lymphoma (ATL), or chronic lymphocytic leukemia (CLL).

This trial is currently open and accepting patients.

What will happen during the trial?

This will be a dose escalation study in subjects with selected hematological malignancies. KPG-818 will be used in combination with dexamethasone in subjects with MM, and as monotherapy for other selected hematological malignancies. Each dose of KPG-818 will be administered orally until the completion of treatment cycles, or progressive disease (PD), unacceptable toxicity, the subject withdraws, or any other study withdrawal criterion is met.

The highest dose level which may be tested is 5 mg KPG-818 and dose levels 2, 3, 4, and 5 mg and/or intermediate dosing or alternative dosing schedule may be explored. Each dose level (1-4) will be tested using the standard 3+3 design. DLT will be assessed during the DLT evaluation period (Cycle 1) and the treatment of study is divided into 6 cycles.

You may be able to join this trial if you:
