Indaptus Therapeutics Doses First Patient in Second Cohort of Single Dose Ranging Study of Decoy20

Following evidence of marked pharmacodynamic activity in first cohort, Cohort 2 has dose reduced while anticipating a similar effect

NEW YORK, Sept. 19, 2023 (GLOBE NEWSWIRE) -- Indaptus Therapeutics, Inc. (Nasdaq: INDP) (“Indaptus” or the “Company”) announces dosing of the first patient in the second cohort of patients to receive a single dose of Decoy20 in the INDP-D101 trial. This cohort dose is a dose reduction from the previous cohort based on the significant pharmacodynamic effect seen with the first cohort and anticipated optimal Decoy20 safety profile for both weekly dosing and combination approaches.

“This cohort is important to the development of Decoy20 as it may provide sufficient data for us to move Decoy20 to a multi-dosing regimen,” said Dr. Roger Waltzman, Indaptus’ Chief Medical Officer. “To date, we have seen positive signs of an immune response with an anticipated adverse effect profile, and we look forward to seeing whether this lower dose provides similar evidence of increased cytokines that can trigger both innate and adaptive immune responses.”

“We continue to be encouraged by the initial results of the first cohort and look forward to progressing into the multi-dosing regimen as soon as we have enough data,” said Jeffrey Meckler, Chief Executive Officer. The study’s objectives are to assess the safety and tolerability of Decoy20, to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D), as well as to assess Decoy20 pharmacokinetics (PK), pharmacodynamics and clinical activity. More information can be found at www.clinicaltrials.gov.

The Phase 1 study was initiated with a single dose escalation, which is planned to be followed by an expansion with continuous weekly administration of Decoy20. The study is enrolling patients with advanced/metastatic solid tumors, who have exhausted approved treatment options.

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 products 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 products 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 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 products 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, with associated “cold” to “hot” tumor inflammation signature transition. IND-enabling, nonclinical toxicology studies demonstrated safe 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. Indaptus’ Decoy products have also produced significant single agent activity against chronic hepatitis B virus (HBV) and chronic human immunodeficiency virus (HIV) infections in pre-clinical models.
