Study Protocol: Phase-Ib Trial of Nivolumab Combined With Metformin for Refractory/Recurrent Solid Tumors

Although immune checkpoint inhibitors have shown significant survival benefits in the treatment of several cancers, optimal outcomes have been limited to certain subsets of patients. In a previous study, we found that the addition of metformin to nivolumab, an anti-programmed cell death protein 1 (PD-1) antibody, yielded substantial tumor regression in mouse models. Further analysis revealed that the number of tumor-infiltrating CD8 T cells had increased markedly. Based on this result, we have launched an investigator-initiated open-label phase-Ib clinical trial. The objectives of this trial are to investigate the safety, efficacy, and pharmacokinetics of a metformin-nivolumab combination treatment. This study consists of 2 parts. The recommended dose of metformin combined with nivolumab is determined in part 1. The safety and efficacy of the optimal dose of metformin to be delivered in conjunction with nivolumab are examined in part 2. Patient eligibility is based on the following criteria: pathologic diagnosis of refractory/recurrent solid tumor (part 1), and non–small-cell lung cancer or pancreatic cancer refractory to standard primary treatment (part 2); no prior use of immune checkpoint inhibitor; performance status 0 or 1; age ≥ 20 years; and adequate organ function. The primary endpoints are safety in part 1 and safety and pharmacokinetics in part 2. The maximum tolerated dose and recommended dose are determined in part 1 by the 3 + 3 cohort method, and the dose-limiting toxicity evaluation period for each patient is 4 weeks from the start of administration. In part 2, metformin is administered at the optimal dose determined in part 1. Total enrollment is 9 to 18 patients for part 1 and 30 patients for part 2. Enrollment began in 2017, and will be completed by 2019. The University Hospital Medical Information Network registration number for this study is 000028405.     

Safety and Efficacy of PD-1 Inhibitors Among HIV-Positive Patients With Non–Small Cell Lung Cancer

Introduction

Despite widespread administration of programmed death receptor 1 (PD-1) pathway inhibitors among individuals with NSCLC, little is known about the safety and activity of these agents among human immunodeficiency virus (HIV) – infected patients since this population has largely been excluded from immunotherapy clinical trials.

Phase 1/2 Study of the Safety and Tolerability of Nivolumab Plus Crizotinib for the First-Line Treatment of Anaplastic Lymphoma Kinase Translocation — Positive Advanced Non–Small Cell Lung Cancer (CheckMate 370)

Introduction

Crizotinib, an anaplastic lymphoma kinase (ALK) inhibitor, is a first-line treatment for ALK translocation–positive advanced non–small cell lung cancer (NSCLC); however, patients eventually progress. Immunotherapies, including the programmed death-1 inhibitor nivolumab, have resulted in durable responses and long-term overall survival in patients with NSCLC. We hypothesized that combining targeted therapy with immunotherapy could result in more patients with responses and/or more durable responses. Herein we report data from a study assessing nivolumab plus crizotinib in patients with previously untreated advanced ALK translocation–positive NSCLC.

Patient-Reported Outcomes From Patients Receiving Immunotherapy or Chemoimmunotherapy for Metastatic Non–Small-Cell Lung Cancer in Clinical Practice

IntroductionImmunotherapy and chemoimmunotherapy clinical trials for metastatic non–small-cell lung cancer (mNSCLC) have generally excluded patients with poor performance status (PS) and have utilized patient-reported measures that could miss some symptoms associated with immunotherapy. The goals of this study were to describe quality of life and symptom burden among mNSCLC patients receiving immunotherapy in clinical practice, and to examine burden by Eastern Cooperative Oncology Group performance status (ECOG PS) and age.Patients and MethodsBetween 2017 and 2018, mNSCLC patients receiving immuno/chemoimmunotherapy at an academic medical center completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) and the National Cancer Institute Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). Univariate and bivariate analyses described EORTC-QLQ-C30 subscales and the proportion reporting at least moderate PRO-CTCAE symptoms, and compared scores by ECOG PS (0/1 vs. 2/3) and age (< 70 vs. ≥ 70 years).ResultsSixty patients (60% female; 75% < 70 years old; 68% ECOG PS 0/1; 57% receiving single-agent immunotherapy) participated. The mean EORTC-QLQ-C30 global health score was 62.6; EORTC symptoms were highest for fatigue, insomnia, dyspnea, and financial concerns (all > 30). Global health and pain were worse in ECOG PS 2/3 patients. For PRO-CTCAE, 20% to 40% reported at least moderate gastrointestinal, respiratory, dermatologic, arthralgia, or myalgia symptoms. The PRO-CTCAE pain score was higher among ECOG PS 2/3 patients.ConclusionIn clinical practice, global health was largely comparable to published clinical trials, but PRO-CTCAE items indicated a higher symptom prevalence. Closer monitoring of symptoms is warranted in ECOG PS 2/3 patients.
