According to the most recent NCCN Guidelines for Kidney Cancer (2024), there are currently several important adjuvant trials, but the most promising data comes from the KEYNOTE-564 trial using pembrolizumab, which has shown significant benefits in disease-free survival (DFS). However, it's important to note that this trial included mainly clear cell RCC patients, with limited papillary RCC representation.

For papillary RCC specifically, according to the European Society for Medical Oncology (ESMO) guidelines, two trials are particularly noteworthy:

The MK-3475-B16/KEYNOTE-B16 trial

Specifically designed for non-clear cell RCC including papillary
Investigating pembrolizumab in the adjuvant setting
Currently ongoing and actively recruiting

The PROSPER trial (EA8143)

Investigating perioperative nivolumab
Includes papillary RCC patients
Has potential to be particularly promising due to its novel perioperative approach

The National Cancer Institute (NCI) clinical trials database indicates that the KEYNOTE-B16 trial may be the most promising specifically for papillary RCC because:

It's the first adjuvant trial specifically designed to include a substantial proportion of non-clear cell RCC patients
It builds on the successful safety profile established in KEYNOTE-564
It addresses an unmet need in papillary RCC treatment

However, I must emphasize that you should discuss clinical trial participation with your oncology team, as eligibility criteria and availability vary. Your healthcare providers can best determine which trial might be most appropriate for your specific situation.
