Samus Therapeutics Announces Study Publication in Communications Biology on the Importance of Epichaperome Inhibition for Enhancing the Vulnerability of Cancer Cells
BOSTON, Dec. 1, 2021 /PRNewswire/ -- Samus Therapeutics, Inc. ("Samus Therapeutics" or the "Company"), a privately held, Boston-based biopharmaceutical company developing epichaperome inhibitors to treat cancer and central nervous system (CNS) diseases, today announced the publication on November 25, 2021 of an open article in Communications Biology about how epichaperome inhibition by zelavespib (PU-H71) can increase the vulnerability of cancer cells to traditionally poor performing therapeutics.
The article, "Pharmacologically controlling protein-protein interactions through epichaperomes for therapeutic vulnerability in cancer," reported that PU-H71 can dramatically increase sensitivity of pancreatic cell lines or patient tumor extracts to established therapeutics. It also demonstrates a direct link between cancer cell survival and epichaperome formation, and between cancer cell vulnerability and epichaperome disruption by PU-H71. Considering these findings, the authors propose a therapeutic strategy using PU-H71 to induce a state of vulnerability to currently used drugs and thus enhance their effectiveness.
"It is well known that cancer cells continuously evolve and acquire the ability to evade the effects of established therapeutics," said Barbara Wallner, PhD, Chief Scientific Officer of Samus Therapeutics. "Epichaperomes, tight protein complexes that act as multi-molecular scaffolds, mediate alterations in protein-protein interactions associated with the disease and pathologically remodel cellular processes. Inhibition of epichaperomes with PU-H71 disrupts epichaperome activity, causes structural dissociation and induces cancer cell death."
"These findings that PU-H71 can act synergistically with established therapeutics to potentially enhance their effectiveness aligns with our current clinical development strategy evaluating the compound in hematological malignancies," added Dr. Wallner.
Disclosures: The study was led by Gabriela Chiosis, PhD, Member of the Chemical Biology Program at the Sloan Kettering Institute at Memorial Sloan Kettering Cancer Center. Dr. Chiosis has intellectual property and financial interests related to Samus Therapeutics.
