Background
Phase I Trial Design
Treatment options for metastatic gastrointestinal
neuroendocrine neoplasms (mNEN) include
resection, systemic somatostatin analogues (SSA),
systemic agents and peptide receptor radionuclide
therapy (PRRT).
Rose bengal disodium (PV-10), is an investigational
autolytic immunotherapy that can yield
immunogenic cell death and disease-specific
functional adaptive immunity
This phase 1 trial evaluated PV-10 as a monotherapy
for mNEN when delivered via intralesional (IL)
injection.
Evaluating safety, tolerability, and impact on
symptoms and biochemical markers resulting from IL
PV-10 administered percutaneously to hepatic lesions
in patients with hepatic mNEN.
Patients were required to have progressive mNEN
following standard therapy, not amenable to resection
or other potentially curative therapy.
Eligible lesion(s) were 1.0 – 3.9 cm in longest
diameter
Cohort 1 (n = 6) received PV-10 to a single lesion per
treatment cycle. Cohort 2 (n = 6) could receive injection
to multiple lesions per treatment cycle.
Patients could receive further PV-10 ≥6 weeks after
prior injection following restaging at week 6.
The primary endpoint was safety.
