On July 30, 2018 Advaxis, Inc. (NASDAQ:ADXS), a late-stage biotechnology company focused on the discovery, development and commercialization of immunotherapy products, reported that the U.S. Food and Drug Administration (FDA) has allowed the Company’s IND application for its ADXS-HOT drug candidate for non-small cell lung cancer (NSCLC) (Press release, Advaxis, JUL 30, 2018, View Source [SID1234527949]). Advaxis anticipates that because of this timely allowance, the first patient in the Phase 1/2 trial for this NSCLC drug candidate will be dosed by the end of 2018.

ADXS-HOT is a cancer-type specific immunotherapy approach that leverages the Company’s proprietary Lm technology platform to target hotspot mutations that commonly occur in specific cancer types as well as other proprietary tumor-associated antigens. To date, more than 10 drug candidates have been designed for different tumor types in the ADXS-HOT program.
"This is an exciting time for Advaxis as we prepare to initiate the first clinical trial with a drug candidate from our ADXS-HOT program. This drug candidate, ADXS-503, has been designed for the treatment of patients with NSCLC," said Kenneth A. Berlin, President and Chief Executive Officer of Advaxis. "With our increased strategic focus on neoantigen-based therapeutics, including the personalized, patient-specific approach of our ADXS-NEO program, already in a clinical trial, we anticipate having five neoantigen-based drug candidates in clinical evaluation by the end of 2019. Our next two ADXS-HOT drug candidates will focus on prostate and bladder cancers. These two tumor types, along with NSCLC, were prioritized based on our evaluation of a number of factors relating to each, including the unmet medical need, time and investment required to demonstrate meaningful clinical activity and immunological sensitivity," concluded Mr. Berlin.
The Company plans to initiate a Phase 1/2 clinical trial that will seek to establish the safety, tolerability and effectiveness of ADXS-503 administered alone and in combination with a checkpoint inhibitor in approximately 50 patients with metastatic NSCLC in different lines of therapy, at up to 20 centers across the U.S.
"I am pleased we can move forward to advance our first trial with ADXS-503, the first drug candidate in our ADXS-HOT program. This is an important clinical milestone as we seek to demonstrate proof-of-concept for ADXS-HOT immunotherapy in NSCLC, where there remains significant unmet need despite the introduction of checkpoint inhibitors and targeted therapies," said Andres Gutierrez, M.D., Ph.D., Chief Medical Officer and Executive Vice President of Advaxis. "Earlier drug candidates from our Lm platform expressing a single antigen have shown a favorable safety profile and preliminary clinical activity in more than 500 subjects treated to date across different tumor types. This clinical experience with prior Lm drug candidates, combined with our ability to leverage the large capacity of our Lm vector to express multiple neoantigens and other tumor-associated antigens, provides the foundation for our belief that ADXS-HOT drug candidates such as ADXS-503 for NSCLC can provide a new standard for off-the-shelf neoantigen vaccines."
Advaxis affirms plans to submit a total of four INDs for drug candidates from its ADXS-HOT program by the fourth quarter of 2019. Beyond NSCLC, prostate cancer and bladder cancer, the fourth ADXS-HOT drug candidate will be selected from breast, colorectal, ovarian or head and neck cancers.
About ADXS-HOT
ADXS-HOT is a program that leverages the Company’s proprietary Lm technology to target hotspot mutations that commonly occur in specific cancer types. ADXS-HOT drug candidates are designed to target acquired shared or "public" mutations in tumor driver genes along with other cancer-testes and oncofetal tumor-associated antigens that also commonly occur in specific cancer types. Although ADXS-HOT drug candidates have not yet been tested in patients, they are an off-the-shelf treatment approach been designed to potentially treat all patients with a specific cancer type, without the need for pretreatment biomarker testing, biopsy, DNA sequencing or diagnostic testing.
About ADXS-NEO
ADXS-NEO is an investigational personalized Lm-based immunotherapy designed to generate immune response against mutation-derived tumor-specific neoantigens identified through DNA sequencing of a patient’s own tumors. The program focuses on creating a customized treatment for each patient targeting multiple neoantigens found in a biopsy of the patient’s tumor. ADXS-NEO is being developed in partnership with Amgen.
