Provectus Biopharmaceuticals Expands Sponsored Research Collaboration with University of Calgary (Canada) to Investigate Systemic Administration of Pharmaceutical-Grade Rose Bengal for Treatment of Pediatric Leukemia

KNOXVILLE, TN, Aug. 17, 2022 (GLOBE NEWSWIRE) — Provectus (OTCQB: PVCT) today announced that the Company has expanded its sponsored research program with Aru Narendran, MD, PhD, Professor, Departments of Pediatrics, Oncology, Biochemistry & Molecular Biology, and Physiology & Pharmacology at the Cumming School of Medicine of the University of Calgary in Calgary, Alberta, Canada to investigate systemic administration of Provectus’ pharmaceutical-grade rose bengal for the treatment of pediatric leukemia. The Company’s innovatively-assembled and proprietary rose bengal is the lead member of a class of small molecules called halogenated xanthenes.

As part of this new sponsored research, the Narendran team plans to:

  • Identify clinically-feasible drug combinations and synthetic lethality that have synergistic activity with Provectus’ rose bengal,
  • Evaluate systemic drug administration routes for maximal tolerability,
  • Evaluate the modulation of WNK1 (lysine deficient protein kinase 1) and other related pathways induced by the Company’s rose bengal, and
  • Complete demonstration of STING (stimulator of interferon genes) dimerization in leukemia cells.

The Narendran team has previously shown:

  • In vitro activity and target modulation effects of Provectus’ rose bengal against several different pediatric leukemia‐derived cell lines and primary cells,
  • Proof‐of-concept of several potential mechanisms that may be involved in this process,
  • Rose bengal’s ability to induce STING dimerization and the molecule’s association with heat shock proteins, and
  • Preliminary evidence of in vivo activity in mouse xenograft models using the pediatric leukemia cell line SEM following oral doses of the Company’s rose bengal.
