BLUE BELL, Pa., March 07, 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 reported financial results for the three and twelve months ended December 31, 2018 and provided a corporate update.

“We made significant progress advancing our portfolio of oral factor D inhibitors in the fourth quarter of 2018,” said Joe Truitt, President and Chief Executive Officer at Achillion. “ACH-4471 has demonstrated preliminary proof-of-concept in patients with paroxysmal nocturnal hemoglobinuria (PNH) and C3 glomerulopathy (C3G). We look forward to reporting updated interim results for our Phase 2 trial of ACH-4471 for PNH, in combination with a C5 inhibitor, in the second quarter of 2019. We plan to present data for the PNH and C3G trials to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019. We also remain on track to complete the ongoing ex-US Phase 1 multiple ascending dose (MAD) study for our more potent next-generation oral factor D inhibitor, ACH-5228. We anticipate submitting an Investigational New Drug (IND) Application in the US for ACH-5228 in the fourth quarter of 2019.”
  
Mr. Truitt continued, “We took several important steps to strengthen our leadership team and expand the Company’s capabilities from a discovery engine to a clinical-stage organization in 2018. Additionally, we were pleased to announce that the Board of Directors recently elected Nicole Vitullo as Chair and we added Brian Di Donato as Senior Vice President and Chief Financial Officer to our executive management team. We also expanded our operations into the Philadelphia area which adds access to a strong talent pool for future growth. We remain well positioned to advance our first- and next-generation oral factor D inhibitors in patients with serious medical conditions. In 2019, we will continue to focus on expanding our clinical operations for PNH and C3G. We now have 24 trial sites recruiting patients for C3G. We also plan to evaluate the potential of our oral small molecule complement inhibitors in additional indications to deliver on the promise of complement inhibition across a wide spectrum of diseases.”

Fourth Quarter 2018 Financial Results

For the three months ended December 31, 2018, the Company reported a net loss of $16.6 million, compared to a net loss of $23.2 million in the three months ended December 31, 2017.

Research and development expenses were $12.2 million for the three months ended December 31, 2018, compared to $15.7 million for the same period of 2017. The decrease was primarily due to decreased personnel costs due to fewer employees combined with decreased discovery research costs related to ACH-5228. These amounts were partially offset by increased manufacturing expenses for ACH-5228.

For the three months ended December 31, 2018, general and administrative expenses totaled $6.0 million, compared to $8.7 million for the same period of 2017. The decrease was primarily the result of the Company’s payment of the underwriting fees in connection with the public resale by the Johnson and Johnson Development Corporation (JJDC) in November 2017 of all the shares of common stock it acquired from the Company in 2015. 

Year-end 2018 Financial Results

For the year ended December 31, 2018, the Company's net loss was $70.3 million, or $0.51 per share, compared to a net loss of $85.2 million, or $0.62 per share, for the year ended December 31, 2017.

For the year ended December 31, 2018, research and development expenses totaled $50.1 million, compared to $63.6 million for the year ended December 31, 2017. The decrease was primarily due to manufacturing and formulation costs related to ACH-5228, discovery research costs, and personnel costs and non-cash stock compensation due to fewer employees. These amounts were partially offset by increased clinical trial costs related to ACH-4471 and increased pre-clinical costs related to ACH-5548.

General and administrative expenses were $23.9 million for the year ended December 31, 2018, compared to $26.0 million for the year ended December 31, 2017. The decrease was primarily due to decreased corporate legal fees and consulting fees combined with the Company’s payment of $2.9 million in underwriting fees in connection with the sale by JJDC in November 2017 of all of the shares of the Company’s common stock it acquired pursuant to the JJDC Stock Purchase Agreement. These amounts were partially offset by an increase in personnel and non-cash stock-based compensation charges related to the transition of the Company’s former chief executive officer and former chief financial officer.

Cash, cash equivalents, and marketable securities at December 31, 2018 were $271.0 million.

Financial Guidance

The company expects net cash usage for 2019 will be approximately $80 million based on current operating plans, anticipated timelines and the estimated costs of clinical trials and product development programs.

About ACH-4471, Complement Factor D Inhibitor for PNH and C3G
Achillion’s first-generation oral complement factor D inhibitor, ACH-4471, is being evaluated for safety and efficacy with Phase 2 clinical programs in both PNH and C3G and has demonstrated preliminary proof-of-concept in both indications. The PNH program consists of a Phase 2 clinical trial evaluating ACH-4471 in patients who are inadequately controlled or sub-optimally responding to eculizumab. Additionally, the Company continues to dose patients in its PNH monotherapy extension trial. The C3G program consists of two Phase 2 clinical trials which are currently recruiting, a six-month blinded, placebo-controlled study and a 12-month open-label study.
