BOLD-100 Development Pipeline

Clinical Investigations

BOLD-100 is the most clinically advanced ruthenium-based therapeutic currently in development.

Previously, BOLD-100 successfully completed a Phase 1 monotherapy dose escalation study in advanced cancer patients that showed BOLD-100 was generally safe and well-tolerated with a safety profile suggesting that it could be combined with other anti-cancer therapies.

BOLD-100 has a granted an Orphan Drug Designation (ODD) in pancreatic cancer. An ODD in gastric cancer was recently filed.

BOLD-100 is currently in a Phase 1b clinical trial in combination with FOLFOX for the treatment of advanced gastric, pancreatic, colon and bile duct cancers (NCT04421820).

Molecular Structure

BOLD-100:
Oncology

BOLD-100 is an anticancer agent being developed in combination with standard of care therapies, to improve patient outcomes in difficult to treat cancers. Most current treatment strategies for advanced cancers are either effective in only some patient populations or have high relapse rates - BOLD-100 is designed to be used in combination with these treatments to enhance response rates. BOLD-100 alters the unfolded protein response (UPR) through selective GRP78 inhibition; and induces reactive oxygen species (ROS) which causes DNA damage and cell cycle arrest. Collectively, these effects result in cell death in both sensitive and resistant cancers. BOLD-100 thus has a unique potential to improve patient care in a wide range of solid and liquid tumors when combined with standard therapies.

Molecular Structure

BOLD-100:
COVID-19

The global fight against COVID-19 (SARS-CoV-2) requires novel therapeutic approaches to improve patient outcomes. BOLD-100 impacts a previously non-targeted pathway that is important for SARS-CoV-2 infection and replication.

  • BOLD-100 was one of four therapeutics selected for funding by the Canadian Government NRC-IRAP program for COVID-19 therapeutic development.
  • Bold Therapeutics has comprehensive preclinical data supporting the use of BOLD-100 against COVID-19.
  • Bold Therapeutics is leading a global consortium of COVID-19 experts.
  • BOLD-100 is initially being developed as a therapeutics for COVID-19, but has potential across a wide range of challenging current and emerging pathogens.
