NCT06811272 | NOT YET RECRUITING | Relapsed Large B-cell Lymphoma

Outpatient Epcoritamab As 2L in NTE R/R DLBCL
Sponsor:

Massachusetts General Hospital

Information provided by (Responsible Party):

Julie E. Haydu, MD, PhD

Brief Summary:

The purpose of this study is to measure the efficacy of the study drug, epcoritamab, in participants with relapsed/refractory large B-cell lymphoma.

Condition or disease

Relapsed Large B-cell Lymphoma

Refractory Large B-cell Lymphoma

Intervention/treatment

Epcoritamab

Phase

PHASE2

Detailed Description:

This is a phase 2 study of outpatient administration of epcoritamab in non-transplant eligible large B-cell lymphoma that has relapsed after, or is refractory to, 1 prior line of therapy. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has approved epcoritamab as a treatment option for your disease after at least two prior treatments. The study treatment may continue for up to 24 cycles or until disease progression, unacceptable toxicity, or withdrawal. Participants will be followed for up to 24 months after last dosage of epcoritamab, or until disease progression or withdrawal, whichever occurs first. After 24 months or at time of progression, participants may be followed annually for survival status. It is expected that about 30 people will take part in this research study.

Men must also agree not to donate sperm during this period. Men may agree to remain abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term or persistent basis) OR agree to use a male condom, and their female partner must use an additional highly effective contraceptive method with a failure rate of \<1% per year when having sexual intercourse if they are a WOCBP (including pregnant females).

              Exclusion Criteria
              • * Participant must not have used an investigational drug or approved systemic lymphoma therapy within 28 days preceding the first dose of study drug. Steroids for lymphoma disease control are permitted but must be stopped at least 7 days prior to the first dose of study drug.
              • * Participants must not have received prior CD20/CD3 bispecific antibody.
              • * Participants must not have received prior autologous or allogeneic stem cell transplant.
              • * Participants must not have received prior anti-CD19 CAR T-cell therapy.
              • * Participants who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> Grade 1) with the exception of alopecia. At the discretion of the overall PI, participants with residual toxicities \> Grade 1 may be considered eligible if in the opinion of the overall PI the residual toxicity is not likely to interfere with the safety or efficacy assessment of the investigational regimen. For residual hematologic toxicities greater than Grade 1.
              • * Participants must not have known central nervous system involvement by lymphoma.
              • * Participants must not have a current life-threatening illness, medical condition, or organ system dysfunction (other than the disease under study) which, in the Investigator's opinion, could compromise the subject's safety or put the study at risk.
              • * Participants must not have an uncontrolled active infection. Localized fungal infection of skin or nails are permitted.
              • * Participants must not have active uncontrolled autoimmune disease. Autoimmune disease under control with chronic systemic corticosteroids at a dose of 10 mg/day of prednisone or less, or equivalent corticosteroid, are eligible.
              • * History of allergic reactions attributed to compounds of similar chemical or biologic composition to epcoritamab. A history of an infusion reaction to CD20-directed therapy is not considered an allergic reaction.
              • * Women who are pregnant are excluded from this study because it is unknown if epcoritamab can cause embryo-fetal harm when administered to a pregnant woman. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with epcoritamab, breastfeeding should be discontinued if the mother is treated with epcoritamab on study.
              • * Participant must not have active uncontrolled HIV infection. Participants with HIV are eligible if disease is adequately controlled on an antiretroviral regimen that is in accordance with the current international AIDS Society guidelines, with adequate control defined by presence of both an undetectable viral load, a CD4 count \>350, no evidence of AIDS-defining illness (with the exception of a lymphoma diagnosis), and no active opportunistic infections (infections controlled on appropriate anti-infective therapy are permitted).
              • * Participant must not have active hepatitis B infection. Participants with positive HBV core antibody or HBV surface antigen at screening are eligible if HBV viral load is negative by PCR and they are on appropriate antiviral therapy.
              • * Participant must not have active hepatitis C infection. Participants with positive Hepatitis C antibody due to prior resolved disease can be enrolled, only if a confirmatory negative Hepatitis C RNA test is obtained. Note: Participants with negative Hepatitis C antibody test are not required to also undergo Hepatitis C RNA testing.
              • * Subject has no known active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. If a subject has signs/symptoms suggestive of SARS-CoV-2 infection or has had recent known exposure to someone with SARS-CoV-2 infection, the subject must have a negative molecular (e.g., PCR) test, or 2 negative antigen test results at least 24 hours apart, to rule out SARS-CoV-2 infection. Note: SARS-CoV-2 diagnostic tests should be applied following local requirements/recommendations. Subjects who do not meet SARS-CoV-2 infection eligibility criteria must be screen failed and may only rescreen after they meet the following SARS-CoV-2 infection viral clearance criteria: No signs/symptoms suggestive of active SARS-CoV-2 infection AND negative testing (molecular (e.g., PCR) result or 2 negative antigen test results at least 24 hours).
              • * Participants must not have received a live virus vaccine within 28 days of first dose of study drug.
              • * Participants must not have any known past or current malignancy other than inclusion diagnosis, except for
                • 1. Cervical carcinoma of Stage 1B or less.
                • 2. Non-invasive basal cell or squamous cell skin carcinoma.
                • 3. Non-invasive, superficial bladder cancer.
                • 4. Prostate cancer with a current PSA level \<0.1 ng/mL.
                • 5. Any curable cancer with a complete response (CR) of \>2 years duration
