Carcinoma of unknown primary
Carboplatin & Paclitaxel (CP)
CP: Carboplatin & Paclitaxel
Regimen
Study | Dates of enrollment | Evidence | Comparator | Comparative Efficacy |
---|---|---|---|---|
Forde et al. 2022 (CheckMate 816) | 2017-2019 | Phase 3 (C) | 1a. CP & Nivolumab 1b. CVb & Nivolumab 1c. DC & Nivolumab |
Inferior EFS |
Note: there were additional comparator options depending on histology; see the respective histology-specific pages for more details. This study was conducted in the United States. The reason for the study was that an unanswered question at the time was whether adding an immune checkpoint inhibitor would improve outcomes.

Chemotherapy
- Carboplatin (Paraplatin) AUC 5 or 6 IV once on day 1
