PolyPid Announces Positive Preclinical Data from OncoPLEX Intra-Tumoral Cancer Therapy Program
Single Local Treatment of OncoPLEX Showed Improved Overall Survival and Significantly Less Tumor Recurrence, and Reduced Systemic Toxicity Compared to Multiple Injections with Standard Systemic Chemotherapy in a Syngeneic Mouse Model for Solid Tumors of Colon Carcinoma
Company Intends to Complete an IND Package with Additional Preclinical Studies in Various Solid Tumor Types, Followed by the Initiation of a Phase 1 Clinical Trial in 2022
In a syngeneic mouse model for solid tumors of colon carcinoma, a single local application of OncoPLEX at the intra-operative setting post tumor resection compared to the group treated with six cycles of systemic docetaxel treatment with 2-4 days gap between cycles, generated the following key results:
- OncoPLEX arm showed 25% overall tumor recurrence at the end of the study (day 39 post-surgery) compared to 75% in the systemic treatment arm, and 100% in the untreated control arm.
- OncoPLEX arm demonstrated 75% overall tumor free survival at the end of the study (day 39 post-surgery), compared to 25% in the systemic treatment arm, and 0% in the untreated control arm.
- OncoPLEX arm demonstrated 75% overall survival at the end of the study (day 39 post-surgery), compared to 50% in the systemic treatment arm, and 0% in the untreated control arm.
Dose response was also demonstrated for OncoPLEX in these studies.
Systemic toxicity was lower following the local application of OncoPLEX versus systemic docetaxel. Additional data in a pharmacokinetic model showed that the maximal plasma concentration of docetaxel was >10 times lower with OncoPLEX than with systemic docetaxel.
“We believe the benefits of our PLEX platform, including the ability to generate constant and high local concentration of drug over a prolonged period, can also potentially be leveraged as an anti-cancer therapy,” said Dr.
