  • Seven subjects in cohort two intravenously dosed with RECCE® 327 (R327) at 150mg met all endpoints - indicating R327 is safe and well tolerated
  • Independent Safety Committee clears third study cohort to be dosed at 500mg - a tenfold increase from cohort one (50mg) and a threefold increase from cohort two (150mg) in dose per approved protocol
  • Third cohort dosing of R327 (500mg) on track to begin this week

SYDNEY, Australia, Jan. 19, 2022 (GLOBE NEWSWIRE) -- Recce Pharma (ASX:RCE, FSE:R9Q) (the Company), the company developing new classes of synthetic anti-infectives, is pleased to report further positive data from its Phase I intravenous (IV) clinical trial of RECCE® 327 (R327), demonstrating safety and tolerability among seven healthy male subjects in cohort two. Based upon these clinical data readouts, an Independent Safety Committee has approved a tenfold increase from the initial dosing of cohort one (50mg) and a threefold increase from cohort two (from 150mg to 500mg) among 7-10 healthy subjects (cohort three). Subjects are expected to be recruited this week and dosed immediately thereafter at Adelaide’s CMAX clinical trial facility.

“We are pleased to see R327 (150mg) was successfully tolerated as an intravenous infusion in cohort two subjects,” said James Graham, Chief Executive Officer of Recce Pharmaceuticals. “Having successfully cleared two dosing levels (50mg and 150mg), we look forward to embarking upon this next significant milestone.”

Cohort Two (R327 - 150mg) Complete – Demonstrated Safety and Tolerability
R327 was shown to be safe and well tolerated at the 150mg dose with no clinically significant changes in vital signs, adverse events, or laboratory parameters associated with R327.

The Phase I trial is an ascending dose, randomized, placebo-controlled, parallel, double-blind, single-dose study being conducted at Adelaide's CMAX clinical trial facility. The study is evaluating the safety and pharmacokinetics of R327 in 7-10 healthy subjects per dose, across eight sequential dosing cohorts of 50-16,000mg (Trial ID ACTRN12621001313820). The study is on track to have all Phase I dosing complete by Q2 2022.

According to PEW Charitable Trusts global antibiotic pipeline review, R327 is the only clinical-stage new class of antibiotic in the world being developed for sepsis, the largest unmet medical need in human health.1
