A Randomised, Double-blind, Placebo-controlled, Phase I/II Trial of RNActive®-Derived Cancer Vaccine (CV9104) in Asymptomatic or Minimally Symptomatic Patients With Metastatic Castrate-refractory Prostate Cancer
The study is the first clinical study with the new prostate cancer vaccine CV9104. This
vaccine is composed of 6 RNActive-based compounds, each encoding for an antigen that is
overexpressed in prostate cancer compared to healthy tissues. RNActive-based vaccines are a
novel class of vaccines based on messenger RNA.
The study is a double-blind randomized placebo-controlled phase I/II trial in men with
asymptomatic- minimally symptomatic metastatic castrate-refractory prostate cancer.
The phase 1 (safety lead- in) part of the trial has the primary objective to assess the
safety of CV9104 and to determine the dose for the randomized phase II part.
The primary objective of the phase II part is to compare overall survival in patients
treated with CV9104 compared to patients treated with placebo.

Interventional
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Phase I (Safety Lead-In): Occurence of dose-limiting toxicity (DLT) during the first 4 weeks of treatment (after administration of 3 vaccinations and after a 1 week observation period
Safety Lead in Portion: Patients will receive CV9104 at a starting dose of 1920 µg in weeks 1, 2 and 3. Safety lead-in patients will be observed for DLTs until 1 week after Vaccination 3 (week 4). In case no DLTs will be observed vaccinations will continue in weeks 5, 7, 9, 12, 15, 18 and 24, then every 6 weeks for up to 12 months after the first vaccination and then every 3 months thereafter until one of the criteria for study treatment discontinuation is met
Up to 4 weeks
