Nivolumab Ipilimumab in Patients With hyperMutated Cancers Detected in Blood (NIMBLe)

• Status: Active, not recruiting
• Trial end date: 2021-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine the safety and effectiveness of nivolumab alone or in combination with ipilimumab in patients with metastatic or unresectable tumors harbouring mutations in genes, POLE and POLD1. These mutations will be determined by plasma cfDNA. Nivolumab and ipilimumab have been given to patients across multiple types of cancer, and safe doses and schedules have been determined.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Canadian Cancer Trials Group
• Collaborators: Bristol-Myers Squibb; Cancer Research Institute, New York City; Personal Genome Diagnostics
• Treatments: Antibodies, Monoclonal; Ipilimumab; Nivolumab

Criteria

Inclusion Criteria:

• Patients must have histologically confirmed advanced (metastatic or unresectable) solid tumors.

• Patients must have received at least 1 standard cancer therapy for their tumor type and progressed on their most recent regimen; patients may be treatment naïve if they refuse standard treatment or there is no standard treatment for their cancer.

• Prior adjuvant/neoadjuvant therapy with curative intent is considered a prior therapy if disease recurrence occurs within at least 6 months.

• Patients may not have received prior immunotherapy

• Patients must consent to blood collection for testing after registration by a central reference laboratory.

• Patients must have clinically and/or radiologically documented disease with at least one lesion measurable as defined by RECIST 1.1.

• Patients must be ≥ 18 years of age.

• ECOG performance status 0 or 1.

• Patients must have adequate hematology and organ function

• Patient consent for screening must be appropriately obtained in accordance with applicable local and regulatory requirements.

• Patients must have solid tumors that demonstrate POLE or POLD1 mutations identified at study entry via plasma cfDNA testing or tumor tissue testing for POLE and POLD1 mutations. A CLIA-certified testing of tumor tissue demonstrating POLE or POLD1 mutation can qualify for eligibility and randomization, however, plasma will be submitted for central cfDNA testing. In the event of discordance between tissue and central laboratory testing, the patient will continue in study but will not be included in the primary analysis. These patients will however be included in the secondary analysis.

• Patients must have recovered to ≤ grade 1 from all reversible toxicity related prior systemic or radiation therapy and have a 2 weeks washout.

• Previous major surgery is permitted provided that it has been at least 28 days prior to patient registration and that wound healing has occurred.

• White Blood Cells ≥ 2.0 x 109/L (2000/µL)

• Absolute neutrophils ≥ 1.5 x 109/L (1500/µL)

• Platelets ≥ 100 x 10^9/L (100 x103/µL)

• Hemoglobin ≥80 g/L* (8.0 g/dL)

• Bilirubin ≤ 1.5 x ULN (upper limit of normal)**

• AST and/or ALT ≤ 3 x ULN

• Serum creatinine ≤ 1.5 x ULN or: Creatinine clearance ≥40 mL/min

• Patients must be willing to consent to provision of archival tissue

• Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements

• Patients must be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other requirements of the trial.

• In accordance with CCTG policy, protocol treatment is to begin within 2 working days of patient randomization.

• Women of childbearing potential (WOCBP) and men who are sexually active with WOCBP must have agreed to use a highly effective contraceptive method

Exclusion Criteria:

• Patients with a history of other untreated malignancies or malignancies, which required therapy within the past 2 years. Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen may be eligible after consultation with the CCTG.

• Patients with primary CNS tumors are not eligible.

• Patients with active brain metastases or leptomeningeal metastases are not eligible. Patients with brain metastases are eligible if these have been treated and clinically stable. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (> 10 mg/day prednisone equivalents). Physiologic replacement doses of systemic corticoidsteroids are permitted, even if >10mg/day prednisone equivalents

• History of primary immunodeficiency, history of allogenic organ transplant that requires therapeutic immunosuppression and the use of immunosuppressive agents within 14 days of study drug administration*

• Active or prior documented autoimmune or inflammatory disorders. Including, inflammatory bowel disease (e.g. colitis or Crohn's disease), diverticulitis with the exception of diverticulosis, celiac disease or other serious gastrointestinal chronic conditions associated with diarrhea), systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome (granulomatosis with polyangiitis), rheumatoid arthritis, hypophysitis, uveitis, etc., within the past 3 years prior to the start of treatment. Patients with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions considered to be of low risk for recurrence are permitted to enroll.

• History of hypersensitivity to nivolumab or ipilimumab or any excipient.

• Any previous treatment with a PD-1 or anti-PD-L1, anti-PD-L2 inhibitor, including nivolumab or an anti-CTLA4, including ipilimumab, or drug specifically targeting T-cell stimulation or immune checkpoint pathways.

• Patients with serious illnesses or medical conditions which would not permit the patient to be managed according to the protocol (including corticosteroid administration), or would put the patient at risk. This includes but is not limited to:

• History of significant neurologic or psychiatric disorder which would impair the ability to obtain consent or limit compliance with study requirements.

• Active infection requiring systemic therapy; (including any patient known to have active hepatitis B, hepatitis C or human immunodeficiency virus (HIV) or tuberculosis or any infection requiring systemic therapy).

• Active peptic ulcer disease or gastritis

• Active pneumonitis.

• Patients receiving concurrent treatment with other anti-cancer therapy or other investigational anti-cancer agents.

• Patients who have experienced untreated and/or uncontrolled cardiovascular conditions and/or have symptomatic cardiac dysfunction (unstable angina, congestive heart failure, myocardial infarction within the previous year or cardiac ventricular arrhythmias requiring medication, history of 2nd or 3rd degree atrioventricular conduction defects).

• Pregnant or lactating women.

• Men who are sexually active with women of childbearing potential and women of childbearing potential must agree to use adequate contraception.
