Lymphoma RadVax LYMPHOMA: A PHASE II TRIAL OF NIVOLUMAB + LOW DOSE RADIOTHERAPY FOR INCOMPLETE RESPONDERS

Phase 2

Terminated

• Conditions: Hodgkin Lymphoma
• Interventions: Drug: Nivolumab

• Registration Number: NCT03495713
• Lead Sponsor: Abramson Cancer Center at Penn Medicine

Brief Summary

This is a Phase II single-arm, single-site, open label clinical trial with r/r HL patients, aimed to determine whether a RadVax approach using low-dose RT added to nivolumab can improve response among patients who do not achieve a CR to nivolumab alone. The long-term goal is to develop an effective regimen for r/r HL patients.

Detailed Description

Nivolumab 3 mg/kg will be administered on day 1 (pre-response assessment week 0) and on day 1 and continued per standard of care and institutional practices. At the week 1 biomarker collection, research FDG PET/CT will be performed to assess for FDG "flare." At week 8-12, PET/CT will be performed for the first response assessment. If a complete anatomic response is seen, nivolumab monotherapy will be continued on day 1 and continued per standard of care and institutional practices.

By contrast, if at week 8 less than a complete anatomic response is seen, radiotherapy to 4 Gy x 2 fractions will be administered (post-response assessment week 0). The patient will be evaluated by a radiation oncologist while on treatment, and toxicities will be recorded. Nivolumab will be continued on day 1 and continued per standard of care and institutional practices.

In either scenario, a second response assessment will be conducted \~8-12 weeks after the first response assessment. In either scenario, nivolumab monotherapy will be continued at the discretion of the treating medical oncologist.

If there is less than CR post-RT and there is an additional untreated non-target lesion that can be followed, radiotherapy can again be administered when disease progresses to a previously untreated lesion, after which the patient will continue on the post-RT follow-up algorithm.

Exclusion Criteria

• Subjects with contraindications to immune checkpoint therapy, as follows:
• Interstitial lung disease that is symptomatic or may interfere with the detection and management of suspected drug-related pulmonary toxicity.
• Prior organ allograft or allogeneic bone marrow transplantation.
• Subjects with contraindications to immune checkpoint therapy, as follows:
• Interstitial lung disease that is symptomatic or may interfere with the detection and management of suspected drug-related pulmonary toxicity.

Arm && Interventions

Group	Intervention	Description
Single Arm	Nivolumab	Subjects will receive initial treatment with the immunomodulatory agent, nivolumab, followed by low-dose (4 Gy x 2) involved-site radiotherapy in subjects with less than an anatomic CR after the first restaging scan. Patients with anatomic CR will continue nivolumab alone without radiotherapy. Eligible patients will have r/r disease with at least 2 sites of measurable disease, and must be eligible for treatment with nivolumab.
