NCT07233668

Brief Summary

The goal of this clinical trial is to learn whether the timing of surgery (cytoreductive nephrectomy) improves outcomes when combined with immunotherapy (ipilimumab and nivolumab) in adults with metastatic clear cell renal cell carcinoma. The main questions this study aims to answer are:

  • Does upfront (immediate) surgery before immunotherapy improve survival compared to delayed surgery after immunotherapy?
  • What medical problems (side effects or complications) occur with each treatment sequence?
  • How do the two strategies affect quality of life? Researchers will compare two groups:
  • Upfront surgery group: Participants will have surgery first, then receive 4 cycles of ipilimumab/nivolumab, followed by nivolumab maintenance.
  • Deferred surgery group: Participants will receive 4 cycles of ipilimumab/nivolumab first, then surgery, followed by nivolumab maintenance. Participants will:
  • Be randomly assigned to one of the two groups
  • Undergo regular clinic visits, imaging tests, and blood collections for safety and biomarker studies
  • Be followed for 15 months to check disease progression, complications, survival, and quality of life This trial will help determine the best timing for surgery in the era of immunotherapy and provide evidence for improved treatment strategies for patients with metastatic kidney cancer

Outcome Measures

Primary Outcomes (1)

  • Progression-Free Survival (PFS) assessed by RECIST version 1.1

    Time from randomization to first documented disease progression or death from any cause, whichever occurs first. Disease progression will be assessed according to RECIST version 1.1 criteria and clinical evaluation.

    Up to 15 months after treatment initiation

Secondary Outcomes (11)

  • Overall Survival (OS)

    Up to 15 months after treatment initiation

  • Rate and Severity of Perioperative Complications Assessed by Clavien-Dindo Classification

    Within 90 days after cytoreductive nephrectomy

  • Rate and Severity of Perioperative Adverse Events Assessed by CTCAE v4.0

    Within 90 days after cytoreductive nephrectomy

  • Radiologic Tumor Response Rate Assessed by RECIST v1.1

    At baseline, at 12 weeks (after 4 cycles of ipilimumab/nivolumab induction therapy), and every 12 weeks thereafter up to 15 months

  • Rate of Unresectable Tumors in the Deferred Arm

    At the time of planned deferred cytoreductive nephrectomy

  • +6 more secondary outcomes

Study Arms (2)

Upfront Cytoreductive Nephrectomy (CN)

EXPERIMENTAL

Participants will undergo immediate cytoreductive nephrectomy. About 4 weeks after surgery, they will receive induction therapy with ipilimumab plus nivolumab for 4 cycles, followed by maintenance nivolumab. Regular assessments of progression, perioperative complications, safety, and quality of life will be performed for 15 months.

Drug: Ipilimumab plus NivolumabProcedure: Cytoreductive Nephrectomy

Deferred Cytoreductive Nephrectomy (CN)

EXPERIMENTAL

Participants will first receive 4 cycles of ipilimumab plus nivolumab induction therapy. After reassessment, they will undergo deferred cytoreductive nephrectomy, followed by maintenance nivolumab. Safety, perioperative complications, progression, and quality of life will be evaluated regularly for 15 months

Drug: Ipilimumab plus NivolumabProcedure: Cytoreductive Nephrectomy

Interventions

Surgical removal of the primary kidney tumor (cytoreductive nephrectomy), performed either upfront (before systemic therapy) or deferred (after 4 cycles of ipilimumab/nivolumab induction), depending on randomization arm.

Deferred Cytoreductive Nephrectomy (CN)Upfront Cytoreductive Nephrectomy (CN)

Participants will receive 4 cycles of ipilimumab combined with nivolumab as induction therapy, followed by nivolumab maintenance depending on randomization schedule (before or after surgery).

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants must meet all of the following:
  • Age ≥ 19 years (male or female).
  • Histologically confirmed synchronous metastatic clear cell renal cell carcinoma.
  • ECOG performance status 0-1.
  • At least one measurable metastatic lesion (per RECIST v1.1).

  • History or suspicion of autoimmune disease incompatible with immune checkpoint inhibitor therapy.
  • Requirement for systemic corticosteroid therapy \>10 mg/day prednisone equivalent, or other immunosuppressive drugs.
  • Any other condition judged by the investigator to make the patient unsuitable for trial participation.
