Targeted drug therapies have greatly improved outcomes for patients with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphoma. However, single drug therapies have limitations, therefore, the current study is evaluating a novel oral combination of targeted drugs as a way of overcoming these limitations. This study will determine the efficacy of the triple combination therapy, DTRM-555, in patients with R/R CLL or R/R non-Hodgkin's lymphoma.


This study is being conducted in three parts: Phase Ia, Phase Ib and Phase II, disease-specific expansion cohorts. Phase Ia explored escalating doses of a monotherapy of a novel Bruton's Tyrosine Kinase (BTK) inhibitor, DTRMWXHS-12. Phase Ib explored two combination therapies, DTRM-505 (DTRMWXHS-12 and everolimus) and DTRM-555 (DTRMWXHS-12, everolimus and pomalidomide).

The current Phase II study will further examine the investigational triple combination treatment, DTRM-555 for efficacy and safety. The study is being conducted in five disease-specific cohorts: Activated B-Cell (ABC) Diffuse Large B-Cell Lymphoma, Germinal Center B-Cell (GCB) Diffuse Large B-Cell Lymphoma, Richter's Transformation, transformed Follicular Lymphoma, and relapsed or refractory Chronic Lymphocytic Leukemia.

The Primary Objective of the Phase II study is to determine the efficacy of the triple combination therapy, DTRM-555, in the five disease-specific cohorts. The Secondary Objectives are (1) to determine the safety of DTRM-555 in the cohorts and (2) to obtain the pharmacokinetics of DTRM-555 (i.e., DTRMWXHS-12, everolimus and pomalidomide).

Inclusion Criteria

Patients must provide written informed consent
Patients with a diagnosis of R/R CLL or other B-cell neoplasms (i.e., ABC DLBCL, GCB DLBCL, Richter's transformation and tFL) who have no available approved therapies, or patients with a diagnosis of non-Hodgkin's lymphoma, which has relapsed and/or is refractory to standard therapy
Patients with R/R CLL must have been exposed to Bruton's tyrosine kinase (BTK) or B-Cell CLL/Lymphoma 2 (BCL2) inhibitor-based therapy in prior lines of therapy but must not have known Cys481 resistance mutation prior to study enrollment

Ability to swallow and retain capsules and/or tablets
Absence of uncontrolled intercurrent illnesses, including uncontrolled infections, cardiac conditions, or other organ dysfunctions
If the patient consents to an optional tumor biopsy, he/she must have a tumor that can be safely biopsied and undergo a baseline tumor biopsy procedure, or be willing to provide available archival tissue collected within 6 months of signing the Informed Consent Form (ICF), and one post-Cycle 1 treatment biopsy
Patients must have at least one target lesion according to Lugano Classification. Patients with R/R CLL are exempt from this requirement
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 of child-bearing potential, for the duration of the study and for at least 4 weeks after the last drug administration, even if they have undergone a successful vasectomy

Exclusion Criteria

Received prior systemic anticancer treatment within the following time frames
Chemotherapy, immunotherapy, radiotherapy or any other investigational therapy within 21 days prior to starting study treatment
Targeted therapies within 5 biological half-lives prior to starting study treatment

study until resolution of the infection; however, patients on prophylactic

antibiotics, antifungals or antivirals are eligible for entry into the study
Aspartate transaminase (AST) or alanine transaminase (ALT) > 2.5 x upper limit of normal (ULN); for patients with liver involvement, > 5 x ULN
Total bilirubin > 1.5 x ULN (Patients with a history of Gilbert's syndrome may participate if total bilirubin is less than or equal to 3 x ULN and the AST/ALT and alkaline phosphatase meet the protocol-specified levels for eligibility)

Patients with bone marrow impairment will be excluded if their absolute neutrophil count (ANC) is < 0.5 x 109/L and platelets < 50 x 109/L
