Advaxis Announces Updated Survival Data in Phase 1/2 ADXS-PSA Trial at the ASCO Genitourinary Cancers Symposium - Seite 2

KEYNOTE-046 was an open-label, multicenter, dose-determining safety and tolerability Phase 1/2 trial of 50 heavily pretreated patients conducted in two parts (Part A and Part B), with a Phase 2 expansion cohort. The objective of the study was to evaluate ADXS-PSA alone (Part A) and in combination with KEYTRUDA (Part B) for primary endpoints that include safety, tolerability and dosing. Secondary endpoints included anti-tumor activity, progression-free survival and overall survival, and exploratory endpoints that include associations between biomarkers of immunologic response (serum PSA) with clinical outcomes. Enrollment in the study has been completed and the database lock occurred on January 28, 2020. The majority of treatment-related adverse events consisted of transient and reversible Grade 1-2 chills/rigors, fever, hypotension, nausea and fatigue. The combination of ADXS-PSA and KEYTRUDA has appeared to be well-tolerated, to date, with no additive toxicity observed.

About KEYNOTE-046
KEYNOTE-046 (NCT02325557) was a Phase 1/2 open-label, multicenter, dose-determination and expansion trial that evaluates the safety, tolerability and preliminary clinical activity of ADXS-PSA as monotherapy (Part A; n=14 [13 treated]), and in combination with KEYTRUDA (Part B; n= 37) in heavily pretreated patients with progressive and refractory mCRPC.

About Advaxis, Inc.
Advaxis, Inc. is a clinical-stage biotechnology company focused on the development and commercialization of proprietary Lm-based antigen delivery products. These immunotherapies are based on a platform technology that utilizes live attenuated Listeria monocytogenes (Lm) bioengineered to secrete antigen/adjuvant fusion proteins. These Lm-based strains are believed to be a significant advancement in immunotherapy as they integrate multiple functions into a single immunotherapy and are designed to access and direct antigen presenting cells to stimulate anti-tumor T cell immunity, activate the immune system with the equivalent of multiple adjuvants, and simultaneously reduce tumor protection in the tumor microenvironment to enable T cells to eliminate tumors.
