What is the purpose of this trial?

This trial aims to determine if the cancer treatments nivolumab (Opdivo) and pembrolizumab (KEYTRUDA or MK-3475) can be administered less frequently without losing effectiveness. It will compare the standard dosing schedule to an extended schedule to assess the necessary frequency of medication for patients. Individuals with locally advanced or metastatic cancer who are already candidates for these treatments might be suitable for the trial. Participants should not have previously received similar immune therapies or plan to take certain drug combinations.

As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to contribute to groundbreaking research.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that both nivolumab and pembrolizumab are generally well-tolerated by patients. Research indicates that switching to longer intervals between doses does not increase the risk of side effects. Specifically, studies confirm that taking nivolumab less often is just as safe as the regular schedule, with no increase in side effects. Similarly, for pembrolizumab, taking it less often does not lead to a higher risk of immune-related side effects. Overall, the safety of these longer schedules aligns with expectations from regular dosing. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the immunotherapy dosing trial because it explores the potential benefits of extended interval dosing for cancer treatments, specifically using nivolumab and pembrolizumab. Unlike the standard treatment schedule, which involves more frequent administrations, this trial investigates whether less frequent dosing can maintain effectiveness while potentially reducing side effects and improving patient convenience. By modifying the dosing schedule, researchers hope to enhance the quality of life for patients without compromising the efficacy of the treatment. This approach could represent a significant shift in how immunotherapy is delivered, offering a more patient-friendly option.

What evidence suggests that this trial's treatments could be effective for cancer?

This trial will compare extended interval dosing with standard interval dosing for immunotherapy in cancer. Studies have shown that both nivolumab and pembrolizumab effectively treat various cancer types. Research suggests that administering nivolumab less frequently can still be effective and might enhance patients' quality of life. Similarly, less frequent dosing of pembrolizumab does not appear to increase severe side effects compared to more frequent dosing, indicating it can be just as safe and effective. Early evidence suggests that spreading out doses for both treatments might still control cancer effectively, allowing patients to receive treatment less often without losing its benefits. ^{1 4 5 6 7}

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.

Nivolumab and pembrolizumab are FDA-approved monoclonal antibodies that target PD-1, helping to enhance T cell activity against cancer by blocking the PD-1/PD-L1 interaction, which allows cancer cells to escape immune detection.

Both drugs have shown efficacy across multiple cancer types, including melanoma and non-small cell lung cancer, and are considered interchangeable options for treating these conditions, which may help manage the rising costs of cancer therapies.

In a study involving 1,453 patients with advanced melanoma and non-small cell lung cancer (NSCLC), pembrolizumab showed no dependency on dosage for overall survival, indicating that varying doses (2 to 10 mg/kg) did not significantly affect patient outcomes.

A strong association was found between the baseline clearance (CL0) of pembrolizumab and overall survival, suggesting that higher clearance rates may indicate more severe disease, rather than affecting the drug's efficacy directly.

In a study of 71 melanoma patients, the incidence of immune-related adverse events (IrAEs) was similar between those receiving nivolumab every 2 weeks (40%) and those receiving it every 4 weeks (50%), indicating that extended dosing is as safe as the original regimen.

Patients on the Q4W dosing experienced a potentially later onset of IrAEs, and most adverse events were mild (grade 1-2), suggesting that Q4W dosing not only maintains safety but also reduces the frequency of clinic visits and patient exposure to viruses.

In a study of 69 patients with solid tumors receiving extended dosing intervals of nivolumab or pembrolizumab, 21.7% developed immune-related adverse events (irAEs), particularly during the first cycle of treatment.

Patients with pre-existing anti-thyroid antibodies were found to have a significantly higher risk of developing irAEs after starting extended dosing intervals, indicating that these patients should be monitored closely during treatment.

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating unresectable or metastatic melanoma based on two clinical trials involving 1,374 patients, showing significant improvements in overall survival compared to ipilimumab, with hazard ratios indicating a reduced risk of death.

Patients receiving pembrolizumab also experienced significant improvements in progression-free survival, although some immune-mediated adverse reactions like hypothyroidism and pneumonitis were noted, highlighting the importance of monitoring for side effects.

The REFINE-Lung study (NCT05085028) is a UK multicentre phase 3 trial that aims to optimize the dosing frequency of pembrolizumab, an anti-PD-1 therapy, for patients with advanced non-small-cell lung cancer, addressing concerns about overtreatment and its associated costs and side effects.

This study employs a novel multi-arm multi-stage response over continuous interventions (MAMS-ROCI) design, which allows for more efficient exploration of multiple dosing strategies compared to traditional trial designs, potentially leading to significant improvements in patient care and treatment optimization across various cancers.

In a study of patients with advanced melanoma, the combination of pembrolizumab and ipilimumab showed significant antitumor activity, with objective response rates of 55% for the 50 mg ipilimumab regimen and 61% for the 100 mg regimen, indicating effective treatment options.

The 50 mg ipilimumab regimen resulted in a lower incidence of severe treatment-related adverse events (24%) compared to the 100 mg regimen (39%), suggesting that this combination may offer a safer alternative with reduced toxicity.

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

Pembrolizumab, an immune checkpoint inhibitor, can cause pneumonitis in 1%-5% of patients, and this case report highlights an atypical presentation of this side effect in a patient with metastatic squamous cell carcinoma.

The patient was successfully treated with steroid therapy after ruling out other potential causes, leading to complete resolution of the pneumonitis, emphasizing the importance of recognizing and managing atypical cases of checkpoint inhibitor-pneumonitis.
