Pancreatic NET - null regimens

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.

Regimen

Study	Dates of enrollment	Evidence	Comparator	Comparative Efficacy	Comparative Toxicity
Rinke et al. 2009 (PROMID)	2001-2008	Phase 3 (C)	Octreotide LAR	Inferior TTP
Caplin et al. 2014 (CLARINET)	2006-2013	Phase 3 (C)	Lanreotide	Inferior PFS
Raymond et al. 2011 (A6181111)	2007-2009	Phase 3 (C)	Sunitinib	Inferior PFS	Less diarrhea; Seems to have better insomnia
Yao et al. 2011 (RADIANT-3)	2007-2009	Phase 3 (C)	Everolimus	Inferior PFS
Xu et al. 2020 (SANET-p)	2016-2019	Phase 3 (C)	Surufatinib	Inferior PFS

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.
