Testing the Combination of Copanlisib, Nivolumab and Ipilimumab in Patients With Advanced Cancer and Lymphoma

Phase Ib Study of Copanlisib in Combination With Nivolumab or With Nivolumab and Ipilimumab

This phase Ib trial studies the side effects and best dose of copanlisib and nivolumab and side effects of copanlisib given together with nivolumab and ipilimumab in treating patients with solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or lymphoma. Copanlisib stops tumors from growing by blocking proteins that are known to be important for tumor cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving copanlisib together with nivolumab or with nivolumab and ipilimumab may work better in treating patients with solid tumors or lymphoma.

PRIMARY OBJECTIVES:

I. To establish the safety, tolerability, and the recommended phase 2 dose (RP2D) of copanlisib and nivolumab combination in patients with advanced solid tumors and lymphomas.

II. To evaluate the safety and tolerability of copanlisib combined with nivolumab and ipilimumab in patients with advanced solid tumors and lymphomas.

EXPLORATORY OBJECTIVES:

I. Evaluate the effect of the doublet and triplet combinations on markers of anti-tumor immunity in circulating immune cells and pre- and post-treatment tumor biopsies.

II. Evaluate the effect of the combinations on biomarkers of AKT inhibition, deoxyribonucleic acid (DNA) damage (gammaH2AX, pNbs1, Rad51), apoptosis, and epithelial-mesenchymal transition in pre- and post- treatment tumor biopsies.

III. Assess preliminary antitumor activity of the combinations.

OUTLINE: This is a dose-escalation study of copanlisib and nivolumab, followed by a dose-expansion study.

COHORT I (DOUBLET TREATMENT PLAN): Patients receive copanlisib intravenously (IV) over 1 hour on days 1 and 15 or days 1, 8, and 15 of each cycle and nivolumab IV over 30 minutes on day 1 or days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) scan and/or magnetic resonance imaging (MRI) throughout the trial. Patients undergo blood sample collection on study and during follow-up, as well as tumor biopsy on study. Patients also undergo an echocardiography (ECHO) during screening and as clinically indicated on study.

COHORT II (TRIPLET SAFETY RUN-IN PHASE TREATMENT PLAN): Patients receive copanlisib IV over 1 hour on days 1, 8, and 15 of each cycle, nivolumab IV over 30 minutes on day 1 of each cycle, and ipilimumab IV over 90 minutes on day 1 for cycles 1-4. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan and/or MRI throughout the trial. Patients undergo an ECHO during screening and as clinically indicated on study.

COHORT III (TRIPLET TREATMENT PLAN): Patients receive copanlisib IV over 1 hour on days 1, 8, and 15 of each cycle, nivolumab IV over 30 minutes on day 15 of cycle 1 and then day 1 of each subsequent cycles, and ipilimumab IV over 90 minutes on day 1 for cycles 2-5. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan and/or MRI throughout the trial. Patients undergo blood sample collection on study and during follow-up, as well as tumor biopsy on study. Patients also undergo an ECHO during screening and as clinically indicated on study.

After completion of study treatment, patients are followed up monthly for 4 months.

Patients who received prior therapy with a checkpoint inhibitor and were taken off drug for serious adverse events are excluded. Prior treatment with a PI3K/AKT/mTOR inhibitor, or prior CAR T-cell therapy is allowed

• Copanlisib is primarily metabolized by CYP3A4. Therefore, the concomitant use of strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, indinavir, nelfinavir and saquinavir) and strong inducers of CYP3A4 (e.g. rifampin, phenytoin, carbamazepine, phenobarbital, St. John's Wort) is not permitted from 14 days prior to enrollment until the end of the study. Other medications that are prohibited while on copanlisib treatment:

  • Herbal medications/preparations (except for vitamins)
  • Anti-arrhythmic therapy other than beta blockers or digoxin

• Human immunodeficiency virus (HIV)-positive patients are eligible if on stable dose of highly active antiretroviral therapy (HAART), no clinically significant drug-drug interactions are anticipated with the current HAART regimen, and viral load is undetectable. Patients on HAART regimens that include CYP3A4 inhibitors (e.g. ritonavir or cobicistat) are excluded. All patients must be screened for HIV up to 28 days prior to enrollment

• Hepatitis B (HBV) or hepatitis C (HCV) infection. All patients must be screened for HBV and HCV up to 28 days prior to enrollment using the routine hepatitis virus lab panel. Patients positive for hepatitis B virus surface antigen measurement (HBsAg) and/or hepatitis B virus core antibody measurement (HBcAb) will be eligible if they are negative for HBV DNA; these patients should receive prophylactic antiviral therapy. Patients positive for anti-HCV antibody will be eligible if they are negative for HCV ribonucleic acid (RNA)

• Cytomegalovirus (CMV) infection. All patients must be screened for CMV up to 28 days prior to enrollment. Patients that are positive for CMV DNA by polymerase chain reaction (PCR) are not eligible for the study

• Patients with active autoimmune disease requiring systemic treatment within the past 3 months, a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents are not eligible. Patients with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Patients that require intermittent use of bronchodilators or local steroid injections will not be excluded from the study. Patients with hypothyroidism and stable on hormone replacement or Sjogren's syndrome will not be excluded from the study

• Pregnant or breastfeeding women will be excluded from participation in this trial, as there is no significant preclinical information regarding the effects of nivolumab, copanlisib, and ipilimumab, on a fetus or newborn infant
