Cethromycin HCl: A Differentiated Anti-Infective Asset

The proprietary hydrochloride salt of cethromycin is the molecular foundation of AliquantumRx’s CALM program, combining liver-targeted exposure, prior human safety experience, and strong intellectual property protection.

High Hepatic Exposure Supports Liver-Stage Activity

Cethromycin HCl accumulates preferentially in the liver, where dormant malaria parasites reside.

Its pharmacologic profile supports:

  • High hepatic exposure
  • Sustained tissue persistence
  • Targeted intracellular activity

Validated Mechanism with Liver Advantage

Cethromycin HCl inhibits parasite protein synthesis through apicoplast targeting — a biologically validated pathway relevant to liver-stage malaria.

Safety and Human Exposure Summary

Cethromycin free base has been administered to more than 5,000 human subjects in prior clinical development, establishing a substantial human exposure and safety database. This human exposure supports early clinical development and helps de-risk initial clinical evaluation.

Intellectual Property Protection

Cethromycin HCl is supported by composition-of-matter and formulation intellectual property protecting the hydrochloride salt and associated solid forms. These patents strengthen AliquantumRx’s ability to advance differentiated clinical development and support long-term commercial exclusivity. Additional patent filings and development-stage protections continue to be pursued to support lifecycle management.
