Oral alicaforsen appears safe and well-tolerated Cambridge, UK; 27 September 2018. Atlantic Healthcare plc (“Atlantic Healthcare” or “Company”), a specialist pharmaceutical company focused on developing and commercializing gastrointestinal therapeutics, announces that its Phase 1 trial of an oral alicaforsen tablet for Crohn’s disease found that the formulation appears to be safe and well-tolerated.

The trial was designed to evaluate safety and tolerability and confirm the site of release of the oral alicaforsen tablet, for delivery to the small intestine, where Crohn’s disease is most prevalent. A total of 15 healthy male volunteers received 240mg alicaforsen in oral tablet form on two separate occasions, once with food and once fasted.

The results demonstrated that the oral tablet appeared to deliver product safely, with all tablets disintegrating to release product before the end of the small intestine. In addition, in line with expectations, the trial showed minimal systemic absorption following oral administration, which is desirable for targeted topical activity within the gut.

Atlantic Healthcare will now start planning for a Phase 2b efficacy trial of alicaforsen tablet in Crohn’s.
Toby Wilson Waterworth, CEO, Atlantic Healthcare commented: “We are delighted to have shown that alicaforsen appears to be delivered safely to the small intestine in oral tablet form, and that it is well tolerated. When viewed alongside results from other alicaforsen clinical trials in ulcerative colitis, the minimal systemic absorption reinforces the drug’s potential as a topical product for Inflammatory Bowel Disease, whether administered orally or rectally.”

Alicaforsen has the potential to create a new class of treatment for Inflammatory Bowel Disease (IBD) and other inflammatory diseases. Atlantic Healthcare’s lead program, Camligo™ (alicaforsen) enema for the treatment of pouchitis, is in a Phase 3 trial, with results expected in H1 2019.

Crohn’s disease

Crohn’s Disease is an inflammatory disease which can affect any part of the digestive system, from the mouth to the anus. However, it most commonly occurs in the last section of the small intestine (ileum). Common symptoms can include diarrhoea, abdominal pain and the presence of blood and mucus in the stool. Over time, inflammation can damage sections of the GI tract, resulting in complications which usually require surgery to remove the diseased tissue.

In 2016, there were estimated to be 1.3m patients diagnosed with Crohn’s in the U.S. and European markets (Source: Decision Resources).
