Clinical Trials

A clinical trial sponsored by Merck KGaA, Darmstadt, Germany, has completed evaluating the novel antimalarial agent DDD107498 (also known as M5717). Conducted as a first-in-human Phase 1 study, it evaluated single and multiple ascending oral doses in healthy volunteers to assess safety, tolerability, and pharmacokinetic parameters. These preliminary results establish essential human safety profiles to support the further clinical development of the compound.

Compliance for Clinical Use

Mechanism and Biochemical Profile

DDD107498 selectively binds to Plasmodium falciparum translation elongation factor 2, thereby halting ribosomal translocation and suppressing parasite protein synthesis. This potent inhibition disrupts protein translation across multiple life-cycle stages of the parasite, providing the biological foundation for testing its safety, tolerability, and pharmacokinetics in healthy volunteers during early-phase clinical trials.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
