Brief Summary:
A clinical trial to compare the effectiveness of savolitinib plus durvalumab versus sunitinib in MET-driven (hepatocyte growth factor receptor), unresectable and locally advanced or metastatic PRCC (Papillary Renal Cell Carcinoma).

Condition or disease Intervention/treatment Phase
Papillary Renal Cell Carcinoma Drug: savolitinib Drug: durvalumab Drug: sunitinib Phase 3

Detailed Description:

This is a Phase III, randomised, open label, 3 arm, multi-centre, international study assessing the efficacy and safety of savolitinib plus durvalumab compared with sunitinib in participants with MET-driven (without co-occurring FH mutations), unresectable and locally advanced or metastatic PRCC, who have not received any prior systemic anti-cancer therapy in the metastatic setting. The study will also investigate the contribution of durvalumab to the savolitinib plus durvalumab combination.

Approximately 200 participants will be randomised in a 2:1:1 ratio to one of the following intervention groups: savolitinib (600mg, oral, once daily) plus durvalumab (1500mg IV Q4W), sunitinib (50mg, oral, once daily for 4 consecutive weeks, followed by a sunitinib-free interval of 2-weeks, Q6W), or durvalumab monotherapy (1500mg IV Q4W).

Participants will continue to receive study intervention until objective radiological PD per RECIST 1.1 is assessed by the investigator, unacceptable toxicity occurs, consent is withdrawn or another discontinuation criterion is met.

Depending on the preferred subsequent therapy, participants randomised to the durvalumab monotherapy arm will be eligible to switch to receive savolitinib in combination with durvalumab at the time of objective radiological PD assessed by BICR per RECIST 1.1, without any intervening systemic anti-cancer therapy following discontinuation of durvalumab monotherapy.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression-Free Survival (PFS) /savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months post first subject randomized ]

    Defined as time from randomisation until progression per RECIST 1.1 as assessed by BICR, or death due to any cause.

    The analysis will include all randomised participants as randomised, regardless of whether the participant withdraws from therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST 1.1 progression.



Secondary Outcome Measures :
  1. Overall Survival (OS) /savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months and approximately 42 months post first subject randomized ]
    Defined as time from randomisation until the date of death due to any cause. The comparison will include all randomised participants as randomised regardless of whether the participant withdraws from therapy or receives another anti-cancer therapy.

  2. Objective Response Rate (ORR) / savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months post first subject randomized ]
    Defined as the proportion of participants who have a Complete Response (CR) or Partial Response (PR) as determined by BICR per RECIST 1.1.

  3. Duration of Response (DoR) / savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months post first subject randomized ]
    Defined as the time from the date of first documented response until date of documented progression per RECIST 1.1 as assessed by BICR or death due to any cause.

  4. Disease Control Rate (DCR) at 24 and 48 weeks /savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months post first subject randomized ]
    Defined as the percentage of participants who have a CR or PR or who have Stable Disease (SD) per RECIST 1.1 as assessed by BICR for at least 23 or 47 weeks, respectively after randomisation.

  5. Time from randomisation to second progression or death (PFS2) /savolitinib plus durvalumab relative to sunitinib [ Time Frame: Approximately 28 months and 42 months post first subject randomized ]
