Real World Study of Effectiveness of Sunitinib or Sorafenib to Chinese Unresectable Locally Advanced or Metastatic PRCC

Summary

This is a multi-center, observational, retrospective study designed to characterize the effectiveness and safety of sunitinib or sorafenib monotherapy in the treatment of Chinese adult patients with unresectable and locally advanced or metastatic PRCC, who have not received any prior systemic anticancer therapy in the metastatic setting. Electronic medical record (EMR) data of patients with 1L sunitinib or sorafenib monotherapy will be screened from Grade-A Tertiary hospitals in China. The study period is from 1st September 2007 to 31st December 2024.

Eligibility

Inclusion Criteria:

Patients must meet all the following criteria to be included in the real-world cohort:

1. Age ≥ 18 years at the index date
2. One of the following:

1)diagnosed with unresectable and locally advanced, or metastatic PRCC; 2)diagnosed with unresectable and locally advanced, or metastatic RCC, and with papillary (papillary ≥ 50%) as the dominant and presumed primary histology type.

3.Patients who received 1L therapy of sunitinib or sorafenib 4.Patients with tumor assessment or relevant clinical visit within 6-month follow-up since index date. (The rationale and details of 6-month minimal follow-up is presented in section 3.6). Death events within 6-month will be included.

Exclusion Criteria:

Patients who meet one or more following criteria will be excluded from the real-world cohort:

1. Patients with papillary urothelial carcinoma or renal pelvis cancer of the kidney;
2. Patients with history of another primary malignancy except for malignancy treated with curative intent with no known active disease ≥ 5 years;
3. Patients who received systemic anti-cancer therapy for PRCC prior to the index date; The following is exception:

   Prior systemic anti-cancer therapy in the neoadjuvant or adjuvant setting are acceptable if it was completed more than 12 months before metastatic/recurrent disease was diagnosed.

   For patients who received prior systemic neoadjuvant/adjuvant therapies within 12 months before metastatic/recurrent disease was diagnosed, the neoadjuvant/adjuvant therapy will be counted as 1L therapy.

   Patients are deemed eligible if the first therapy was only sustained for ≤ 3 days.
4. Patients with missing both day and month of index date;
5. Patients with severe conditions that are greater or equal to grade 3 by the definition of CTCAE 5.0 criteria when included into the study;
6. Patients who treated with any combination of chemotherapy, targeted therapy, or immunotherapy with sunitinib or sorafenib as 1L therapy.

Other exclusion criteria revised according to study D5086C00001 (SAMETA) will also be applied, only if explicit evidence can be identified in the EMR data.
