NCT03260504

Brief Summary

This phase I trial studies the side effects and best dose of aldesleukin when given together with pembrolizumab in treating patients with kidney cancer that has spread to other parts of the body. Aldesleukin may stimulate white blood cells to kill kidney cancer cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to avoid recognition by immune cells. Giving aldesleukin and pembrolizumab may work better in treating patients with kidney cancer.

Outcome Measures

Primary Outcomes (1)

  • Number of Adverse Events

    The safety analysis was based on subjects who experienced toxicities as defined by CTCAE v5.0 criteria. Safety was assessed by quantifying the toxicities and laboratory abnormalities by grades experienced, including any serious adverse events (SAEs). Only treatment-related adverse events with an incidence rate of at least 2.5% are reported.

    Adverse events were recorded from the time the consent form was signed through 30 days following the cessation of the study treatment for each participant. Each treatment course was 12 weeks and the maximum duration of treatment was 3 courses (36 weeks).

Secondary Outcomes (3)

  • Number of Participants With Objective Response

    Tumor imaging was collected at baseline after consent was obtained, every 12 weeks at end of a treatment course (max. 3 courses), and every 12 weeks after the cessation of study treatment for up to 1 year of surveillance follow-up for each participant.

  • Number of Participants With Objective Response or Stable Disease

    Tumor imaging was collected at baseline after consent was obtained, every 12 weeks at end of a treatment course (max. 3 courses), and every 12 weeks after the cessation of study treatment for up to 1 year of surveillance follow-up for each participant.

  • Progression Free Survival (PFS)

    Tumor imaging was collected at baseline after consent was obtained, every 12 weeks at end of a treatment course (max. 3 courses), and every 12 weeks after the cessation of study treatment for up to 1 year of surveillance follow-up for each participant.

Study Arms (1)

Treatment (pembrolizumab, aldesleukin)

EXPERIMENTAL

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Patients also receive aldesleukin subcutaneously (SC) 5 days per week for 6 weeks; or aldesleukin IV on days 2-6 of pembrolizumab cycles 1 and 2. Pembrolizumab treatment repeats every 3 weeks for 4 cycles per treatment course in the absence of clinical disease progression or unacceptable toxicity.

Limitations and Caveats

Study enrollment was hampered by changes in frontline treatment options for advanced/metastatic RCC. There was a significant decrease of IL-2 therapy use at our cancer center starting in 2018 which coincided with the FDA approval of ICI-based regimens of nivolumab plus ipilimumab (2018), and pembrolizumab plus axitinib (2019). Study enrollment was also affected by the COVID-19 pandemic as our hospital prioritized efforts to inpatient care for patients with COVID-19 versus elective use of IL-2.
