Non Hodgkin Lymphoma Clinical Trial
Study of a Triple Combination Therapy, DTRM-555, in Patients With R/R CLL or R/R Non-Hodgkin’s Lymphomas
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).
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.
a. 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.
Age ≥ 18 years.
Life expectancy greater than 12 weeks.
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
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.
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.
Patients with active infections requiring therapy are not eligible for entry into the study until resolution of the infection; however, patients on prophylactic antibiotics, antifungals or antivirals are eligible for entry into the study.
Pregnant or lactating individuals.
Impaired hepatic or renal function as demonstrated by any of the following laboratory values:
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)
Alkaline phosphatase > 2.5 x ULN
Glomerular filtration rate < 50 mL/min, as assessed using the standard methodology at the investigating center (i.e., Cockcroft-Gault), or serum creatinine > 1.5 x ULN
International normalized ratio (INR) > 1.5 or other evidence of impaired hepatic synthesis function.
Absolute neutrophil count < 1.0 x 109/L or platelets < 100 x 109/L, unless due to disease-related bone marrow impairment as confirmed by bone marrow biopsy during screening or due to standard of care treatment within 2 months prior to signing of informed consent. 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.
Previous allogeneic bone marrow transplant is restricted, unless transplant was greater than 3 months prior and there is no evidence of acute or chronic graft versus host disease.
Central nervous system involvement with malignancy.
Patients who have poorly controlled diabetes mellitus or whose glucose values cannot be controlled with medical treatment.
Current malignancies of another type, with the exception of adequately treated in situ cervical cancer and basal cell skin cancer, squamous cell carcinoma of the skin or other malignancies with no evidence of disease for 2 years or more.
Known history of human immunodeficiency virus (HIV) or active with hepatitis C virus (HCV) or hepatitis B virus (HBV). Subjects who are positive for hepatitis B core antibody, hepatitis B surface antigen, or hepatitis C antibody must have a negative polymerase chain reaction (PCR) result before enrollment. Those who are PCR positive will be excluded.
Documented or known bleeding disorder.
Requirement for anticoagulation treatment that increases INR or activated partial thromboplastin time above the normal range (low molecular weight heparin and heparin line flush allowed).
Patients requiring the use of strong CYP3A4, CYP1A2, or P-gp inhibitors.
Patients with a significant cardiovascular disease or condition, including:
myocardial infarction within 6 months of study entry,

left ventricular ejection fraction (LVEF) < 45% by multiple gated acquisition (MUGA) and /or echocardiogram (ECHO).
