Safety Study of BTK Inhibitor, DTRMWXHS-12, Used Singly or in Combination, in CLL and B-cell Lymphomas

NCT02900716

Description:

This study will evaluate the safety, antitumor activity and preliminary pharmacokinetics of an investigational drug product, DTRMWXHS-12, in patients with chronic lymphocytic leukemia or other B-cell lymphomas. DTRMWXHS-12 will be evaluated as a single agent, and in combination. This study will be conducted in two parts: phase Ia and Ib. Both parts will explore escalating doses of DTRMWXHS-12. The phase Ia study will evaluate DTRMWXHS-12 monotherapy. The phase Ib study will evaluate DTRMWXHS-12 combinations.

Eligibility Criteria

        Inclusion Criteria:

          -  Patients with a diagnosis of chronic lymphocytic leukemia (CLL) or other B-cell
             neoplasms including small lymphocytic lymphoma (SLL), mantle cell lymphoma (MCL),
             marginal zone lymphoma (MZL) and follicular B-cell non-Hodgkin's lymphoma (FL) who
             have no available approved therapies.

          -  Age > 18 years.

          -  Life expectancy greater than 12 weeks.

          -  Patients must have an ECOG (Eastern Cooperative Oncology Group) performance status 0
             or 1.

          -  Patients must provide written informed consent.

          -  Ability to swallow and retain capsules.

          -  Absence of uncontrolled intercurrent illnesses, including uncontrolled infections,
             cardiac conditions, or other organ dysfunctions.

          -  Women of child-bearing potential must have a negative serum or urine pregnancy test.

          -  Women of child-bearing potential must agree to use 2 reliable methods of contraception
             beginning 4 weeks prior to the initiation of treatment, during therapy, and for at
             least 4 weeks after the last drug administration.

          -  Men must agree to use a latex or synthetic condom during sexual contact with a
             pregnant female or a female who can become pregnant, for the duration of the study and
             for at least 4 weeks after the last drug administration, even if they have undergone a

             investigational therapy within 21 days or 5 half-lives for targeted therapies prior to
             this study entry.

          -  Patients with active infections requiring intravenous (IV) antibiotic/antiviral
             therapy are not eligible for entry onto the study until resolution of the infection;
