Atlantic Healthcare plc (“Atlantic Healthcare” or “Company”), a specialist pharmaceutical company focused on acquiring, developing and commercializing therapeutics that address unmet patient needs and rare diseases, today announced the results of the Phase 3 trial of Camligo™ (alicaforsen enema) for orphan-designated pouchitis.

In the primary analysis, using an adaptation of the Mayo Score of improvement in endoscopic remission and bowel frequency, the trial did not meet its co-primary endpoints.

However, the data for stool frequency do show an encouraging efficacy signal and remission in 34% of patients. In addition, a re-evaluation of the endoscopy data, using new methods of analysis, indicates a statistically significant endoscopic response was achieved in a number of subgroups of patients.

Toby Wilson Waterworth, Chief Executive, Atlantic Healthcare plc said: “Although we are disappointed that the Phase 3 trial did not achieve statistical significance, we believe the percentage of patients achieving remission in stool frequency and the endoscopic response observed in a number of sub populations of patients could be noteworthy. Having consulted with key opinion leaders and regulatory advisors, we now plan to meet with the U.S. Food and Drug Administration and European Medicines Agency to discuss a pathway to regulatory approval.”

He added, “We are grateful to the clinicians and patients who participated in the trial, which confirmed that alicaforsen is safe and well-tolerated, with no drug-related serious adverse events. It is also encouraging to note that the patients who participated in the trial demonstrated strong compliance with alicaforsen enema.”

Prof Brian Feagan MD, FRCPC, an acknowledged expert in IBD and Director at Robarts Research Institute added: “It is challenging to develop treatments for orphan-designated diseases. This study makes a significant contribution to the existing body of knowledge in pouchitis. As long as there is no approved treatment, there remains an unmet medical need. It is therefore encouraging to note that alicaforsen enema may benefit some pouchitis patients.”

About pouchitis

Pouchitis is estimated to impact the lives of approximately 200,000 patients in the U.S. and Europe. It is a progressive disease characterized by inflammation, ulceration and increasingly uncontrolled, frequent and urgent emptying of the bowel (up to 10-20 times a day and night).

Camligo™ (alicaforsen enema) Phase 3 Trial

Camligo™ is the brand name of alicaforsen enema to treat orphan-designated pouchitis. The trial was a Phase 3, multi-center, double-blind randomized controlled trial in subjects with chronic antibiotic refractory pouchitis (failed to adequately respond to one or more courses of antibiotics). The trial recruited 138 patients at 40 centers across the U.S., Canada and Europe. Patients received Camligo™ 240mg once daily for six weeks, or placebo. The primary endpoints of the trial were the proportion of patients achieving endoscopic remission and a reduction in stool frequency at week 10. Secondary endpoints assessed improvement in Quality of Life.
