Alloplex has developed a highly-differentiated, non-engineered, tumor-agnostic cellular therapy platform with broad anti-tumor activity.
Preclinical in vitro and animal model data indicate that the platform is applicable across multiple tumor types.
Alloplex Biotherapeutics Inc. is a privately-owned Boston-based cellular therapeutics company founded in 2016. The concept on which it is based was developed by its scientific founder, Dr. Frank Borriello MD, PhD, after observing that many scientific reports indicated that activation of various known immune pathways each resulted in some degree of anti-tumor activity.
Recognizing the advantage of consolidating the activity of multiple immune pathways into a single therapeutic, Dr. Borriello envisioned using a proprietary engineered cell line to train a patient’s white blood cells to recognize and kill cancer cells.
Alloplex reduced this concept to practice with two specialized engineered tumor cells lines, collectively called ENLIST cells. ENLIST cells display an array of protein ligands targeting receptors on multiple PBMC subsets. ENLIST cells activate multiple immune pathways in PBMC in a synergistic manner to yield non-engineered SUPLEXA therapeutic cells which possess potent anti-tumor activity. The SUPLEXA therapeutic cells are comprised of cells long known by the scientific community to individually possess anti-tumor activity and represent elements of both the innate and adaptive immune systems.
The concept is protected by a combination of patent (U.S. Provisional 62/425424, issued as U.S. Patent 10,731,128 on August 4, 2020) and trade secrets.
Over the past five years, Alloplex has refined a first generation autologous SUPLEXA cell drug candidate and the organization is poised to initiate a Phase 1 first-in-human clinical trial in Q4, 2021 in Australia.
Alloplex sought the opinion of a number of cellular therapy experts to solicit their unbiased opinions regarding the differentiation and potential SUPLEXA therapeutic cells. Their reactions were universally positive.
