Indaptus Therapeutics Announces Clinical Supply Agreement with BeiGene to Evaluate Novel Cancer Treatment Combinations

Planned industry first clinical trial combining BeiGene’s checkpoint inhibitor tislelizumab with Indaptus’ broadly targeted, short duration systemic immune stimulator Decoy20 expected to start in 2025

Indaptus Therapeutics Management will hold a conference call on October 22, 2024 at 4:30PM ET to discuss the agreement and future plans

NEW YORK, Oct. 22, 2024 (GLOBE NEWSWIRE) — Indaptus Therapeutics, Inc. (Nasdaq: INDP), a clinical-stage biotechnology company pioneering innovative cancer and viral infection treatments, today announced a clinical supply agreement with BeiGene. Building on Indaptus’ preclinical observation that Decoy20, when combined with a PD-1 inhibitor, induced complete cancer regressions and immunological memory in animal models, Indaptus plans to advance human clinical evaluation of the combination of BeiGene’s anti-PD-1 antibody, tislelizumab, with Indaptus’ Decoy20, a novel treatment designed to induce a broad immune response to fight cancer.

Indaptus’ Decoy20 is being studied for its potential to treat a variety of cancers, including liver, colon, and pancreatic. PD-1 inhibitors are considered key agents in modern immunotherapy and have produced impressive response rates in some patients. In preclinical studies, Decoy20, when used in combination with a PD-1 inhibitor and an oral non-steroidal anti-inflammatory agent, demonstrated tumor eradication rates of 80-100%. Indaptus hopes to find a treatment combination that similarly improves outcomes in humans.

“PD-1 inhibitors have proven to be meaningful in treating multiple types of cancer. We are optimistic that we can improve outcomes by broadly and safely stimulating the immune system in a way that could enhance overall effectiveness of currently approved cancer treatments,” said Jeffrey Meckler, CEO of Indaptus Therapeutics. “This agreement with BeiGene marks a significant step forward in the search for curative cancer treatments for some of the most challenging cancers. Additionally, we view this as a significant milestone for Indaptus.”

As part of the agreement, BeiGene will provide Indaptus with access to its PD-1 inhibitor as well as technical expertise in order to accelerate the first clinical trial combining the two investigational drugs. Decoy20 utilizes Indaptus’ unique “Pulse-Prime” approach, which induces a strong and broad boost to the immune system but clears rapidly with only transient and tolerable side effects.

“Decoy20’s ability to synergize with a variety of approved therapeutic modalities, including checkpoint therapy, makes it a promising partner for several novel combination approaches,” said Dr. Michael Newman, Founder and Chief Scientific Officer at Indaptus. “This trial could reshape the checkpoint therapy landscape, as it will be the first time a short but broadly acting agent such as Decoy20, utilizing our innovative Pulse-Prime approach, will be tested in combination with a PD-1 inhibitor.”

Indaptus will seek approval from the FDA to initiate a combination trial, which is anticipated to begin in 2025.

About PD-1 Inhibitors
PD-1 inhibitors are a class of immunotherapy drugs that block the PD-1 (programmed death-1) receptor on T cells, preventing cancer cells from evading immune detection. By inhibiting the interaction between PD-1 and its ligands (PD-L1/PD-L2) on tumor cells, these drugs restore the ability of the adaptive arm of the immune system to recognize and attack cancer cells.

About Indaptus Therapeutics
Indaptus Therapeutics has evolved from more than a century of immunotherapy advances. The Company’s novel approach is based on the hypothesis that efficient activation of both innate and adaptive immune cells and pathways and associated anti-tumor and anti-viral immune responses will require a multi-targeted package of immune system-activating signals that can be administered safely intravenously (i.v.). Indaptus’ patented technology is composed of single strains of attenuated and killed, non-pathogenic, Gram-negative bacteria producing a multiple Toll-like receptor (TLR), Nucleotide oligomerization domain (NOD)-like receptor (NLR) and Stimulator of interferon genes (STING) agonist Decoy platform. The product candidates are designed to have reduced i.v. toxicity, but largely uncompromised ability to prime or activate many of the cells and pathways of innate and adaptive immunity. Decoy product candidates represent an antigen-agnostic technology that have produced single-agent activity against metastatic pancreatic and orthotopic colorectal carcinomas, single agent eradication of established antigen-expressing breast carcinoma, as well as combination-mediated eradication of established hepatocellular carcinomas, pancreatic and non-Hodgkin’s lymphomas in standard pre-clinical models, including syngeneic mouse tumors and human tumor xenografts. In pre-clinical studies tumor eradication was observed with Decoy product candidates in combination with anti-PD-1 checkpoint therapy, low-dose chemotherapy, a non-steroidal anti-inflammatory drug, or an approved, targeted antibody. Combination-based tumor eradication in pre-clinical models produced innate and adaptive immunological memory, involved activation of both innate and adaptive immune cells, and was associated with induction of innate and adaptive immune pathways in tumors after only one i.v. dose of Decoy product candidate, with associated “cold” to “hot” tumor inflammation signature transition. IND-enabling, nonclinical toxicology studies demonstrated i.v. administration without sustained induction of hallmark biomarkers of cytokine release syndromes, possibly due to passive targeting to liver, spleen, and tumor, followed by rapid elimination of the product candidate. Indaptus’ Decoy product candidates have also produced meaningful single agent activity against chronic hepatitis B virus (HBV) and chronic human immunodeficiency virus (HIV) infections in pre-clinical models.
