In June 2007, Arpida announced that it has received approval from the US FDA to initiate Phase II trials with intravenous iclaprim in the treatment of patients with hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP) or healthcare associated pneumonia (HCAP).
An oral formulation of iclaprim has successfully completed three Phase I trials: an ADME study (absorption, distribution, metabolism and excretion) with radiolabelled compound, a Phase I bioavailability trial with a solution and one with a capsule formulation. Iclaprim could be offered not only as an intravenous therapy for hospital use in acute situations, but also as an oral formulation, allowing early patient discharge followed by outpatient treatment. This switch should be a valuable instrument in reducing healthcare costs and enhancing patient comfort.
Arpida's fourth most advanced programme, AR-709, targets upper and lower respiratory tract infections acquired in the community setting. AR-709 exhibited potent activity against a large panel of pneumococcal clinical isolates including those resistant to currently used drugs. Promising results of first-in-man studies with AR-709 were published in March 2007.
An additional compound, AR-2474, has achieved in vivo proof of concept. AR-2474 has been shown to be highly effective in eradicating pathogens in preclinical models of skin infection and nasal carriage.
Apart from the antibiotic programmes, Arpida has an innovative
antifungal therapy (TLT) which is about to enter Phase III
