Abstract 5493


Rocapuldencel-T is an investigational immunotherapy formulated with RNA isolated from the patient's tumor to program autologous dendritic cells with tumor-specific antigens. It is administered chronically via intradermal injection to activate a tumor-specific memory T-cell response.


The Phase 3 ADAPT trial was designed to evaluate overall survival (OS) of rocapuldencel-T in combination (Combo) with standard-of-care (SOC) for the treatment of newly diagnosed mRCC as compared to SOC alone (Control). It included adults with synchronous, clear cell mRCC who were eligible for nephrectomy at 107 sites across North America, Europe and Israel.


462 patients were randomized 2:1 from February 2013 - October 2015. In February 2017, an interim analysis by the Independent Data Monitoring Committee after 75% of the targeted number of 290 events (deaths) prompted a recommendation to stop the trial because the OS hazard ratio was greater than the pre-defined futility boundary (0.98) for the 3rd interim assessment. However, in consultation with investigators and the FDA, the sponsor has continued the trial due to the still maturing survival data, the mechanism of action of rocapuldencel-T, which involves the induction of long-term memory immune responses, and its’ safety profile. The median duration of follow-up was 20 months and more than half the patients in both treatment groups were still alive. Data from the first third of patients randomized (n = 154), and, therefore the longest follow up time and least censored data (44%), suggest a potential survival benefit for the combination worthy of further assessment. Additionally, a statistically significant correlation was observed between the increase in the number of rocapuldencel-T induced memory T cells (CD8+/CD28+/CD45RA-) and OS in patients for whom data has been analyzed and 7 doses of rocapuldencel-T has been administered (n = 114). Updated long-term response and immune data will be presented.


The ADAPT trial is ongoing to further assess the long-term effects of this well-tolerated individualized immunotherapy.
