BLUE BELL, Pa., June 10, 2019 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq: ACHN), a clinical-stage biopharmaceutical company dedicated to transforming the lives of patients and families affected by complement-mediated diseases, today announced that the final data set for ACH-4471 (newly designated “danicopan”) proof of concept Phase 2 trial in untreated patients with paroxysmal nocturnal hemoglobinuria (PNH) was accepted for oral presentation at the 24th Congress of the European Hematology Association (EHA). The 24th Congress of the EHA is being held in Amsterdam, Netherlands from June 13 – 16, 2019. The oral presentation (abstract code S864) is scheduled for June 15, 12:15 pm local time and will be presented by Dr. Peter Browett, BMedSci, MBChB, FRACP, FRCPA from the University of Auckland, Auckland, New Zealand. Topline data from this trial was previously reported by Achillion in December 2018.
Additionally, the Company has received acceptance for the use of the name danicopan for its oral, small molecule factor D inhibitor, ACH-4471, from the United States Adopted Names (USAN) Council and the World Health Organization’s International Nonproprietary Names (INN) Expert Committee.
Presentation Highlights:
The presentation titled “A Phase 2 Open-label Proof-of-concept Study of the Oral, Small Molecule Factor D Inhibitor, ACH-4471, in Untreated Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH)” presents data showing:
- Reduction in lactate dehydrogenase (LDH) at Day 28 (n=10) compared to baseline (primary endpoint)
- Improvement in additional markers of PNH, including hemoglobin, reticulocyte count, bilirubin, clone size, and Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue scores compared to baseline at Days 28 (n=10) and 84 (n=8)
- As previously described in December, one patient discontinued therapy for an SAE however the drug was generally well tolerated with 8 of 10 patients electing to continue into a long-term extension study with durability of effect and long-term tolerability up to 2 years
Following the Annual Congress of EHA, the full presentation will be available in the “Investor & News” section of Achillion’s website: .
About Danicopan (ACH-4471) Phase 2 PNH Monotherapy Trial
The Company’s first-generation oral complement factor D inhibitor, danicopan, was evaluated for safety and efficacy in untreated patients with PNH. This is a Phase 2, open-label, multiple dose trial in adult patients with anemia, defined as a hemoglobin <12 g/dL, and LDH ≥1.5X upper limit of normal (ULN) at enrollment. This clinical trial enrolled ten patients and was comprised of two Parts where patients were administered danicopan orally, three times a day at a dose determined by clinical response. In Part 1 of the study, patients received study medication for 28 days. The primary objective was the reduction in LDH from baseline at Day 28. In Part 2, based on a review of safety and efficacy data through Day 20 along with prespecified LDH reduction criteria, patients, who in the opinion of the Principal Investigator received benefit from danicopan, were offered continued dosing for up to 8 additional weeks. These patients were enrolled into a long-term extension study which began at the conclusion of Part 2.
About Paroxysmal Nocturnal Hemoglobinuria (PNH)
PNH is thought to be caused by a mutation resulting in the absence of receptors normally present on red blood cells (RBCs) that interact with the complement system. The complement system typically functions normally in these patients but due to the lack of key receptors, known as CD55 and CD59, on the surface of the PNH RBCs, the complement system treats these cells as foreign and destroys them via hemolysis in the circulatory system (intravascular) and in the liver or spleen (extravascular). The complement alternative pathway (AP) is a critical factor in the development of extravascular hemolysis. Complement factor D is a critical protein within the amplification loop of the AP and it is believed that inhibiting it could control the AP response. Furthermore, this mechanism of action represents a potentially distinct and unique therapeutic approach for controlling intravascular and extravascular hemolysis associated with PNH.

About Achillion Pharmaceuticals
Achillion Pharmaceuticals, Inc. (Nasdaq: ACHN) is a clinical-stage biopharmaceutical company focused on advancing its oral small molecule complement inhibitors into late-stage development and commercialization. Research has shown that an overactive complement system plays a critical role in multiple disease conditions including the therapeutic areas of nephrology, hematology, ophthalmology and neurology. Achillion is initially focusing its drug development activities on complement-mediated diseases where there are no approved therapies or where existing therapies are inadequate for patients. Potential indications being evaluated for its compounds include paroxysmal nocturnal hemoglobinuria (PNH), C3 glomerulopathy (C3G), and immune complex membranoproliferative glomerulonephritis (IC-MPGN). Each of the product candidates in the Company’s oral small molecule portfolio was discovered in its laboratories and is wholly owned. To advance its investigational product candidates into Phase 3 clinical trials and commercialization, the Company plans to work closely with key stakeholders including healthcare professionals, patients, regulators and payors.
