PROVENGE: POWERFUL OVERALL SURVIVAL DATA

The PROCEED Registry

PROCEED is the largest real-world registry to evaluate the expected safety and survival profile of PROVENGE in men with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). PROCEED enrolled nearly 2000 men who received PROVENGE between 2011 and 2014 in an everyday treatment setting.1,2

PROCEED evaluated the expected safety and survival profile of PROVENGE. Among patients in the lowest baseline prostate-specific antigen (PSA) quartile (≤5.27 ng/mL), nearly half (44.1%) of the men in the registry received no additional cancer treatments for at least 1 year. Of these men, nearly 95% received sipuleucel-T (PROVENGE) as a first-line treatment.1 The National Comprehensive Cancer Network® (NCCN®) recommends sipuleucel-T (PROVENGE) as a first-line treatment option.3

In a post hoc analysis, median overall survival was greatest in men who started PROVENGE with a lower baseline PSA levela

For men whose PSA was ≤5.27 ng/mL: Median overall survival was nearly 4 years from the time of treatment1

In a subanalysis of patients with PSA-matched cohorts, African American men who received PROVENGE lived 20.9 months longer than PSA-matched Caucasian men with baseline PSA ≤29.48 ng/mL. In men with baseline PSA >29.48, median survival was 5.1 months longer for African American men.4,b

aPROCEED was a registry without a control group; all patients received PROVENGE. Patients may have received subsequent anti-cancer interventions per the local investigator’s standard of care.

bPROCEED was a registry to evaluate the safety of PROVENGE in a real-world setting whereby all patients received PROVENGE and there was no control group. The study was conducted to quantify the risk of cerebrovascular events and survival. Patients may have received subsequent anti-cancer interventions per the local investigator’s standard of care. This sub-group analysis of the PROCEED registry was exploratory and results need careful interpretation.

PROCEED findings were consistent with a post hoc analysis of the Phase 3 pivotal IMPACT trial5, which suggested that men who start PROVENGE when their PSA level is lower live longer.c

cThis post hoc analysis was not powered for statistical significance, and the population within the subgroups was not randomized. Therefore, the findings are limited by their exploratory nature.

IMPACT data suggest greater survival benefits for men who received PROVENGE earlier5,d

Data from the exploratory analysis suggest that men with a baseline PSA of ≤22.1 ng/mL when treated with PROVENGE lived more than 1 year longer than men who did not receive PROVENGE (hazard ratio [HR], 0.51; 95% confidence interval [CI], 0.31-0.85).5

dThis post hoc analysis was not powered for statistical significance, and the population within the subgroups was not randomized. Therefore, the findings are limited by their exploratory nature.

IMPACT: PROVENGE extended life for men with mCRPC6

IMPACT: In the pivotal, randomized clinical trial that supported FDA approval of PROVENGE, men who received the immunotherapy experienced a significant overall survival advantage. Nearly 38% more men who received PROVENGE were still alive 3 years posttreatment compared to control. 2

INDICATION

PROVENGE® (sipuleucel-T) is an autologous cellular immunotherapy indicated for the treatment of asymptomatic or minimally symptomatic metastatic castrate-resistant (hormone-refractory) prostate cancer.

IMPORTANT SAFETY INFORMATION

Acute Infusion Reactions: Acute infusion reactions (reported within 1 day of infusion) may occur and include nausea, vomiting, fatigue, fever, rigor or chills, respiratory events (dyspnea, hypoxia, and bronchospasm), syncope, hypotension, hypertension, and tachycardia.

Thromboembolic Events: Thromboembolic events, including deep venous thrombosis and pulmonary embolism, can occur following infusion of PROVENGE. The clinical significance and causal relationship are uncertain. Most patients had multiple risk factors for these events. PROVENGE should be used with caution in patients with risk factors for thromboembolic events.

Vascular Disorders: Cerebrovascular events (hemorrhagic/ischemic strokes and transient ischemic attacks) and cardiovascular disorders (myocardial infarctions) have been reported following infusion of PROVENGE. The clinical significance and causal relationship are uncertain. Most patients had multiple risk factors for these events.

Handling Precautions: PROVENGE is not tested for transmissible infectious diseases.

Concomitant Chemotherapy or Immunosuppressive Therapy: Chemotherapy or immunosuppressive agents (such as systemic corticosteroids) given concurrently with the leukapheresis procedure or PROVENGE has not been studied. Concurrent use of immune-suppressive agents may alter the efficacy and/or safety of PROVENGE.

Adverse Reactions: The most common adverse reactions reported in clinical trials (≥ 15% of patients receiving PROVENGE) were chills, fatigue, fever, back pain, nausea, joint ache, and headache.
