Brief Summary:
The purpose of this study is to compare tumor response, progression free survival (PFS) and overall survival (OS) in newly diagnosed mRCC patients treated with Intuvax (INN: ilixadencel) pre-nephrectomy followed by Sunitinib post-nephrectomy vs Sunitinib post-nephrectomy patients.

Condition or disease Intervention/treatment Phase
Renal Cell Carcinoma, Metastatic Biological: Intuvax (INN: ilixadencel) Drug: Sunitinib Phase 2

Detailed Description:

Patients, all planned for nephrectomy, will be stratified according to the Heng risk criteria (high risk patients vs. intermediate risk patients) and randomized in a 2:1 ratio to receive Intuvax (INN: ilixadencel)+ Sunitinib or Sunitinib alone.

Two doses of Intuvax (INN: ilixadencel) will be administered in to the primary tumour before nephrectomy. The control group will be scheduled for nephrectomy directly.

All patients will start Sunitinib treatment 5-8 weeks after operation.

Results from the phase I study, together with the results reported in the literature on the use of autologous dendritic cells (DCs) in combination with Sunitinib encourage Immunicum aktiebolag (AB) to further investigate the possibility of exploiting Intuvax (INN: ilixadencel) 10 million cells/dose when combined with Sunitinib for the treatment of mRCC patients.

Primary Outcome Measures :
  1. Overall Survival (OS) - Days (FAS) [ Time Frame: From the randomization to the date of death, up to 5 years after the last participant's 18-month survival data. ]

    OS is the time from randomization until date of death. The patients who were alive at the end of study were followed for survival status (alive/date of death) through medical records, databases and public records according to the time frame below.

    Due to censored data, estimates of upper 95% CI could not be determined in all reporting groups.


  2. Overall Survival - Days (PPS) [ Time Frame: From the randomization to the date of death, up to 5 years after the last patient's 18-month survival data. ]

    OS is the time from randomization until date of death. The patients who were alive at the end of study were followed for survival status (alive/date of death) through medical records, databases and public records according to the time frame below.

    Due to censored data, upper 95% CI could not be determined in all reporting groups.


  3. 18-Months' Overall Survival Percentage (FAS) [ Time Frame: At 18 months (544 days) ]
    The 18-month survival percentage was defined as the percentage of patients alive 18 months after randomization.

  4. 18-Months' Overall Survival Percentage (PPS) [ Time Frame: At 18 months (544 days) ]
    The 18-month survival percentage was defined as the percentage of patients alive 18 months after randomization.


Secondary Outcome Measures :
  1. Progression Free Survival (PFS) From Start of Sunitinib According to RECIST 1.1. [ Time Frame: From Sunitinib-Start to progressive disease or death, up to 18 months. ]

    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by radiographic assessment: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

    Due to the large amount of censored data, estimates of median and/or a 95% CI could not be reliably determined in all reporting groups.

    Baseline data are reported for the safety data set (all patients randomized) whereas PFS is analyzed for the full analysis set (FAS). Two patients in the safety data set were not included in the FAS since they withdrew prior to start of treatment.


  2. Objective Response Rate (ORR) From Start of Sunitinib Treatment and Duration of Response in Each Subgroup. [ Time Frame: From start of sunitinib treatment up to 18 months ]
    Objective response rate was defined as the percentage of patients with complete response (CR) and partial response (PR).Tumor response was evaluated centrally according to the RECIST 1.1 guideline.

  3. Number of Participants With Specific Best Overall Response [ Time Frame: From start of sunitinib treatment up to 18 months ]
    The best overall response is the best response recorded from the start of the treatment sunitinib until disease progression/recurrence; taking as reference for progressive disease (PD) the smallest measurements recorded since the treatment started. In general, the patient's best response assignment depended on the achievement of the measurement criteria.

  4. Disease Control Rate [ Time Frame: From start of sunitinib treatment up to 18 months ]
    Best overall response (CR, PR or SD) evaluated from Sunitinib-Start for patients with available data.

  5. Duration of Response [ Time Frame: From first date of CR or PR until date of PD or death, up to 18 months. ]
    The duration of response was calculated for only those patients who responded. It was the time from first objective response to first observed progression of disease or death if the death was due to disease progression (whichever came first).

  6. Duration of Clinical Benefit [ Time Frame: From first date of clinical benefit (CR, PR or SD) until date of PD or death, up to 18 months. ]
    Disease control rate (DCR) also called Clinical Benefit Rate, was defined as the proportion of patients with CR or PR or SD.

  7. Duration of Stable Disease [ Time Frame: From first date of SD until PD or date of death, up to 18 months. ]
    The duration of SD was calculated for only those patients who exhibited a best response of SD response as per RECIST v1.1. It was the time from first SD response to first observed progression of disease or death if the death was due to disease progression (whichever came first), up to 18 months.

  8. Time to Progression (TTP) [ Time Frame: Time from Sunitinib-Start to date of either PD according to RECIST 1.1 or clinical progression as evaluated by the Investigator, up to 18 months. ]
    Due to the large amount of censored data, estimate of upper 95% CI could not be reliably determined in all reporting groups.

  9. Percentage of Tumor Area With Infiltrating Cluster of Differentiation 8+ (CD8+) T-cells [ Time Frame: At resection of primary tumor. ]
    Relative number of tumor-infiltrating CD8+ T-cells in the resected primary tumor compared to number of infiltrating CD8+ T-cells in available diagnostic pre-biopsy (sample from either primary tumor or metastasis), was not to be evaluated as described in the protocol due to missing pre-biopsy samples). Instead an automated and validated quantification of percentage of CD8+ tissue in delineated tumor area was made.
