About this trial
This phase II trial studies how well low dose, reduced frequency nivolumab works in treating patients with cancer that cannot be removed by surgery (unresectable) or that has spread from where it first started (primary site) to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Nivolumab is a type of immune checkpoint inhibitor (ICI). ICIs have revolutionized the treatment of numerous cancers with remarkable improvement in participant outcomes. However, accessibility of ICIs is extremely poor on a global scale, mainly due to high costs. Previous research has suggested that these drugs can be given at lower doses and reduced frequency than their approved dosing regimens, with similar results. Giving nivolumab at a lower dose and less often may help reduce the cost of therapy, improve immunotherapy accessibility, and therefore improve survival outcomes globally.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participants are eligible if they have one of these histologically confirmed, unresectable or metastatic cancer types listed below, based upon historical responsiveness to anti-PD-(L)1 agents
Non-small cell lung cancer (NSCLC) with documented PD-L1 expression (combined positive score [CPS] ≥ 1) (NOTE: Participants with known driver oncogenic mutations/rearrangements, including EGFR, ALK and ROS-1, will be excluded.)
Head and neck squamous cell carcinoma (HNSCC) with documented PD-L1 expression (CPS ≥ 1)
Clear cell renal cell carcinoma (ccRCC) (NOTE: Other subtypes may be permitted after approval by the Medical Monitor)
Disqualifiers
Prior exposure to any immune-checkpoint inhibitor for any reason
Residual adverse event(s) from prior therapy grade > 1 (National Cancer Institute [NCI]-Common Terminology Criteria for Adverse Events [CTCAE] v6.0) that could interfere with study endpoints or put participant safety at risk, as determined by the treating investigator
Known active central nervous system (CNS) metastases and/or prior history of leptomeningeal cancer involvement
Known history of another active malignancy (besides the eligible cancer diagnosis) within the last 3 years from day 1 of nivolumab that could interfere with study endpoints or put participant safety at risk. (NOTE: Exception will be made for adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ [skin, bladder, cervical, colorectal, breast] or low grade prostatic intraepithelial neoplasia or grade 1 prostate cancer. Any other neoplasm, which has been treated adequately and is adjudged by the treating investigator to have a low risk of progression during the study, could be enrolled only after approval from the medical monitor.)

Trial outcomes
Primary outcomes
Objective response
Defined as the best objective response of complete response (CR) or partial response (PR), as determined by investigator assessment per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1.
Secondary outcomes
Duration of response (DOR)
Will be assessed per RECIST 1.1. The Kaplan-Meier (KM) technique will be used to obtain estimates of DOR. For event-based survival analyses in participants without documentation of the event, survival will be censored on the last date the participant was known to be event free. The standard error of the KM estimates will be computed using the Greenwood formula (Kalbfleisch \& Prentice, 2002), and standard errors from the matrix form of Greenwood's formula for cumulative incidence estimates. Median time to event, if reached, will be presented with a 90% confidence interval based on the Brookmeyer and Crowley method (Kalbfleisch \& Prentice, 2002).
Disease control
Defined as achievement of CR, PR, or stable disease as a patient's best objective response to the study treatment, per RECIST v1.1. For event-based survival analyses in participants without documentation of the event, survival will be censored on the last date the participant was known to be event free. The standard error of the KM estimates will be computed using the Greenwood formula (Kalbfleisch \& Prentice, 2002), and standard errors from the matrix form of Greenwood's formula for cumulative incidence estimates. Median time to event, if reached, will be presented with a 90% confidence interval based on the Brookmeyer and Crowley method (Kalbfleisch \& Prentice, 2002).
Progression free survival (PFS)
The KM technique will be used to obtain estimates of PFS. For event-based survival analyses in participants without documentation of the event, survival will be censored on the last date the participant was known to be event free. The standard error of the KM estimates will be computed using the Greenwood formula (Kalbfleisch \& Prentice, 2002), and standard errors from the matrix form of Greenwood's formula for cumulative incidence estimates. Median time to event, if reached, will be presented with a 90% confidence interval based on the Brookmeyer and Crowley method (Kalbfleisch \& Prentice, 2002).
Overall survival (OS)
The KM technique will be used to obtain estimates of OS. For event-based survival analyses in participants without documentation of the event, survival will be censored on the last date the participant was known to be event free. The standard error of the KM estimates will be computed using the Greenwood formula (Kalbfleisch \& Prentice, 2002), and standard errors from the matrix form of Greenwood's formula for cumulative incidence estimates. Median time to event, if reached, will be presented with a 90% confidence interval based on the Brookmeyer and Crowley method (Kalbfleisch \& Prentice, 2002).
