Pancreatic NET - null regimens

Back to Top
The purpose of this page is to provide references to "null therapy" such as placebo and observation. These references provide further insight into the historical development of the treatment landscape. See the main pancreatic NET page for regimens that include active anticancer treatment.

Study 	Dates of enrollment	Evidence 	Comparator 	Comparative Efficacy 	Comparative Toxicity
Rinke et al. 2009 (PROMID) 	2001-2008 	Phase 3 (C)	Octreotide LAR	Shorter TTP 	
Caplin et al. 2014 (CLARINET) 	2006-2013 	Phase 3 (C)	Lanreotide 	Shorter PFSMedian PFS: 18 vs NYR mo(HR 2.13, 95% CI 1.37-3.33) 	
Raymond et al. 2011 (A6181111) 	2007-2009 	Phase 3 (C)	Sunitinib 	Shorter PFS 	Less diarrhea; Seems to have better insomnia
Yao et al. 2011 (RADIANT-3) 	2007-2009 	Phase 3 (C)	Everolimus 	Shorter PFS 	
Xu et al. 2020 (SANET-p) 	2016-2019 	Phase 3 (C)	Surufatinib 	Shorter PFS 	
Chan et al. 2024 (CABINET pancreatic)	2018-10 to 2023-08 	Phase 3 (C)	Cabozantinib 	Shorter PFS (primary endpoint)Median PFS: 4.4 vs 13.8 mo(HR 4.35, 95% CI 2.38-8.33)	
No active antineoplastic treatment. Used as a comparator arm and here for reference purposes only. Note: while the initial A6181111 publication seemed to have a significant survival disadvantage for this arm (p=0.02), this finding was no longer significant at the final update (p=0.094). The primary endpoint (PFS) remains significant.
