A Phase 1b/2 Study of Immune and Targeted Combination Therapies in Participants with RCC (KEYMAKER-U03): Substudy 03A (NCT04626479, EU CT 2023-506838-68-00).

In a pre-planned analysis for KeyVibe-003 and KeyVibe-007 studies, both trials met the pre-specified futility criteria for the primary endpoint of overall survival. In these studies, the safety profile of the fixed-dose combination was consistent with that observed for vibostolimab (MK-7684) and pembrolizumab in previously reported studies, with no new safety signals identified. Based on the lack of efficacy in KeyVibe-003, KeyVibe-007, the previously announced Phase 3 studies, KeyVibe-010 in adjuvant melanoma and KeyVibe-008 in extensive-stage small cell lung cancer, and following the recommendations from the external Data Monitoring Committee (eDMC) to unblind the KeyVibe-003 and KeyVibe-007, crossover all patients receiving MK-7684A to pembrolizumab, and perform no additional analyses for the OS endpoint and secondary endpoints, MSD has decided to discontinue MK-7684/MK-7684A in all studies. This decision is not based on any concerns about the safety of MK-7684/MK-7684A.
Measures taken
The Sponsor issued a Communication to Investigator Letter on December 16, 2024, which is attached, requiring the following actions by investigator and site personnel:

1. All study participants receiving treatment with vibostolimab/pembrolizumab (MK-7684A) should stop treatment with this coformulation and be offered pembrolizumab monotherapy.
2. The participants should be informed within 4 weeks of receiving Communication to Investigator Letter and communication with the participants should be documented in their medical records.
3. The MK-7684A arms will remain open so that remaining participants on treatment will have continued access to pembrolizumab.
4. Data collection will be limited: response data will no longer be collected though documentation of AEs should remain uninterrupted. The study will close once all participants are no longer on study treatment. Second course pembrolizumab for patients currently not on second course treatment will continue to be offered
5. The final visit in the will be the Safety Follow-up Visit. There will be no follow-up for survival status. Participants currently in imaging follow-up or in survival follow-up are considered to have completed the study and therefore should obtain imaging and further oncological care as per local standard of care. However, standard safety reporting should continue, as applicable.

Please find below the number of participants receiving MK-7684A treatment in EEA countries as of 16-Dec-2024:
- France: 1
- Hungary: 0
- Netherlands : 0
- Poland: 3
- Spain : 3

Please note that MK-4280A is mentioned in the &#34;communication to Investigator Letter&#34; but there is no Unexpected Event or Urgent Safety Measure related to this MK-4280A product. This notification is for MK-7684A only.
