NCT05886036

Brief Summary

This phase II trial compares mosunetuzumab to the usual treatment (rituximab) for improving survival in patients with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). Rituximab and mosunetuzumab are monoclonal antibodies. They bind to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Mosunetuzumab may be more effective at extending survival in patients with NLPHL than the usual approach with rituximab.

Study Arms (2)

Arm I (Mosunetuzumab)

EXPERIMENTAL

Patients receive mosunetuzumab SC on days 1, 8, and 15 of cycle 1 and day 1 of subsequent cycles. Treatment repeats every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Patients who experience PD will be permitted to crossover to arm II at week 12. Patients also receive FDG and undergo PET/CT at baseline and end of treatment. Patients who are positive at pre-treatment bone marrow biopsy also receive FDG and undergo PET/CT on study. Patients also undergo bone marrow biopsy and tissue biopsy at baseline, and blood sample collection throughout the trial. Patients may also undergo bone marrow biopsy and tissue biopsy at end of treatment.

Arm II (Rituximab, Rituximab and hyaluronidase human)

ACTIVE COMPARATOR

Patients receive rituximab IV on day 1 and rituximab and hyaluronidase human SC on days 8, 15, and 22 of each cycle. Cycles repeat every 28 days for up to 2 cycles 8 weeks apart in the absence of disease progression or unacceptable toxicity. Patients may receive rituximab IV on days 8, 15, and 22 of each cycle if rituximab and hyaluronidase human is not available. Patients who experience PD will be permitted to crossover to arm I at week 12. Patients also receive FDG and undergo PET/CT at baseline and end of treatment. Patients who are positive at pre-treatment bone marrow biopsy also receive FDG and undergo PET/CT on study. Patients also undergo bone marrow biopsy and tissue biopsy at baseline, and blood sample collection throughout the trial. Patients may also undergo bone marrow biopsy and tissue biopsy at end of treatment.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histopathologically confirmed diagnosis of NLPHL as confirmed by local pathologist's expert review.
  • Untreated NLPHL: stage IB to IV according to Cotswolds. The proportion of patients with stages I or II treated with consolidative radiotherapy will be capped at 40%.
  • Previously treated NLPHL, any stage.
  • According to the treating physician, the patient should not be observed and needs therapy, notably because of B-symptoms (unexplained fever \[temperature \> 38 degrees Celsius (\> 100.4 degrees Fahrenheit)\], weight loss \[unexplained loss of \> 10 percent of body weight over the past six months\], or drenching night sweats), symptomatic nodal or extranodal disease, or patient preferences.
  • Patients must have measurable disease according to the Lugano/Lymphoma Response to Immunomodulatory Therapy Criteria (LYRIC) classification.
  • Age \>= 18 years. Because no dosing or adverse event (AE) data are currently available on the use of mosunetuzumab in patients \< 18 years of age, children are excluded from this study.
  • Eastern Cooperative Oncology Group performance status =\< 2 (Karnofsky \>= 60%).
  • Absolute neutrophil count \>= 1,000/mcL.
  • Platelets \>= 100,000/mcL.
  • Total bilirubin =\< 1.5 institutional upper limit of normal (ULN), except in patients with Gilbert's syndrome as defined by \> 80% unconjugated bilirubin.
  • Aspartate aminotransferase (AST)(serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine transaminase (ALT)(serum glutamic-pyruvic transaminase \[SGPT\]) =\< 3 x institutional ULN.
  • Glomerular filtration rate (GFR) \>= 40mL /min= GFR (mL/Min/1.73 m\^2) \* body surface area (BSA)/1.73.
  • Human immunodeficiency virus-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
  • For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
  • Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
  • +4 more criteria

You may not qualify if:

  • Classical Hodgkin lymphoma (cHL) or composite lymphoma.
  • Transformed NLPHL, concerns of the treating physician of an occult transformation or concerns of the treating physician that the patient needs cytotoxic therapy.
  • NLPHL relapse less than 6 months after rituximab or rituximab-containing therapy.
  • Patients who have not recovered from AEs due to prior anticancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia.
  • Patients who are receiving any other investigational agents.
  • Patients with central nervous system (CNS) involvement as a result of lymphoma.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to mosunetuzumab or rituximab.
  • Patients with uncontrolled intercurrent illness or any other significant condition(s) that would make participation in this protocol unreasonably hazardous.
  • Pregnant women are excluded from this study because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother with mosunetuzumab; breastfeeding should be discontinued if the mother is treated with mosunetuzumab or rituximab. These potential risks may also apply to other agents used in this study.
  • Prior allogeneic stem cell or solid organ transplantation.
  • Participants who have received a live, attenuated vaccine within 4 weeks before first dose of study treatment or anticipation that such a live, attenuated vaccine will be required during the study. Participants must not receive live, attenuated vaccines (e.g., FluMist \[registered trademark\]) while receiving study treatment and after the last dose until B-cell recovery to the normal ranges. Killed vaccines or toxoids should be given at least 4 weeks prior to the first dose of study treatment to allow development of sufficient immunity.
  • Any other anti-cancer therapy, whether investigational or approved, including but not limited to chemotherapy, within 4 weeks or 5 half-lives of the drug, whichever is shorter, prior to initiation of study treatment.
  • Evidence of any significant, concomitant disease that could affect compliance with the protocol or interpretation of results as judged by the investigator, including, but not limited to:
  • Significant cardiovascular disease (e.g., New York Heart Association class III or IV cardiac disease, myocardial infarction within the previous 6 months, unstable arrhythmia, or unstable angina).
  • Significant pulmonary disease (such as obstructive pulmonary disease or history of bronchospasm).
  • +8 more criteria
