Cambridge, UK; August 2, 2018. Atlantic Healthcare plc (Atlantic Healthcare), a specialist gastrointestinal (GI) pharmaceutical company, developing treatments for inflammatory bowel disease and other GI diseases, has appointed John Temperato as U.S. President and Chief Operating Officer, to lead the commercialisation programme of alicaforsen in the U.S..

Atlantic Healthcare is developing alicaforsen for the treatment of inflammatory bowel disease (IBD). Results of the fully-funded Phase 3 trial for alicaforsen enema in the treatment of orphan-designated IBD pouchitis are expected in H1 2019. Pouchitis is a rare and serious form of IBD for which there is no approved therapy and limited treatment options.

Subject to positive results from the trial and subsequent regulatory approval, Atlantic Healthcare will commercialise alicaforsen enema as the first and only approved treatment for pouchitis. Work is also ongoing to develop the pipeline for alicaforsen in additional indications, including distinct and novel tablet formulations to treat Crohn’s disease and ulcerative colitis (UC).

John has a wealth of experience in pharmaceutical sales and marketing. He joins Atlantic Healthcare from Melinta Therapeutics (NASDAQ: MLNT), where he was President and Chief Operating Officer / Chief Commercial Officer responsible for the commercialisation strategy and building the Company’s product portfolio. Prior to Melinta, he headed sales and marketing at Salix Pharmaceuticals (now part of Valeant Pharmaceuticals (NYSE: VRX)), where he successfully launched numerous products, helping to grow revenue from $119 million in 2004 to $2 billion in 2015. John has also held positions at Celltech Pharmaceuticals, Medeva Pharmaceuticals and Adams Laboratories.

John Temperato, U.S. President and COO at Atlantic Healthcare said:

“I am delighted to join Atlantic Healthcare at what is an extremely exciting time. The highly experienced team has deep roots in pharmaceuticals, alicaforsen enema is in the final stages of clinical trials and a promising pipeline is being developed for alicaforsen tablets in additional GI indications.”

Toby Wilson Waterworth, CEO at Atlantic Healthcare said:

“This appointment is an important step in the growth and development of Atlantic Healthcare. John’s experience of taking pharmaceuticals to market will inform our approach to commercialising alicaforsen enema, which will target gastroenterologists in hospitals and specialist care centres in Europe and the U.S., with first commercial revenues anticipated in H1 2020.”

About Pouchitis

Patients who have failed drug treatment options for ulcerative colitis often progress to having their diseased colon being removed, a new rectum created and the bowel reconnected with a procedure called pouch surgery (ileal pouch-anal anastomosis – IPAA). Surgeons use the end of the small intestine (ileum) to create a pouch to act as a new rectum, typically shaped like the letter J. The pouch is attached internally to the area just above the anus to hold faeces before being evacuated.

Pouchitis is the return of inflammatory disease in the pouch. It occurs in approximately half of the people who have the IPAA procedure. Signs and symptoms of pouchitis can include inflammation and ulceration, diarrhoea, abdominal pain, cramps, fever, an increased number of bowel movements, night-time faecal seepage, faecal incontinence, and a strong urge to have a bowel movement.

About Alicaforsen

Aicaforsen Alicaforsen is being developed as a locally active, topical treatment with the potential to establish a new class of therapy, with clear differentiating features, for the treatment of multiple inflammatory GI disorders.

Alicaforsen is in development for the treatment of IBD. An enema formulation is currently in a pivotal Phase 3 trial agreed with U.S., Canadian and European regulatory agencies in patients with active pouchitis. The trial has completed enrollment of 138 patients to approximately 40 trial centres across the U.S., Canada, Europe, and Israel, and is expected to report preliminary data in H1 2019.

There is currently no approved treatment for pouchitis in the U.S. or Europe and there are limited treatment options for UC and Crohn’s disease.

Under a rolling submission agreement with the FDA, Atlantic Healthcare has filed the nonclinical data package of its New Drug Application (NDA) for alicaforsen to treat pouchitis with the regulator. Alicaforsen has also been granted FDA Fast-Track designation, plus U.S. and European Orphan Drug designations for this indication.

Alicaforsen enema has shown, in five Phase 2 clinical trials involving 377 patients with UC and pouchitis, to reduce inflammation and promote mucosal healing with good tolerability and a durable effect. Alicaforsen also has a good safety profile based on data from more than 1,000 patients (enema, parenteral, and IV delivery).
Alicaforsen is an antisense oligonucleotide, which has been designed to interact and down regulate mRNA for ICAM-1, a well-recognised cell-surface protein that is involved in the inflammatory response of both the adaptive and innate components of the immune system, and is over-expressed in patients with IBD.

[1] Research at Atlantic Healthcare has also provided evidence that alicaforsen can interact with TLR-9, an intracellular receptor involved in TLR-9 signaling pathways that activate cells of the innate immune system involved in inflammatory responses.

[2] Atlantic Healthcare Atlantic Healthcare has supplied more than 300 courses of alicaforsen enema to patients in Europe through unsolicited requests via Named Patient Supply regulations. This has provided further evidence of efficacy and safety in the pouchitis [3] and UC indications. {4-6]
