BLUE BELL, Pa., Nov. 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 its financial results for the three and nine months ended September 30, 2019 and provided a corporate update.

“In the third quarter of 2019 we reached a number of important milestones as part of our mission to bring oral complement factor D inhibitors to patients in need,” said Joe Truitt, President and Chief Executive Officer at Achillion. “We look forward to sharing the top-line results from the Phase 2 PNH combination study at the upcoming American Society of Hematology (ASH) Annual Meeting and initiating our Phase 3 program for danicopan in early 2020. Additionally, we continue to advance our second-generation oral factor D inhibitor, ACH-5228, with a planned Phase 2 PNH clinical trial initiation in the first half of 2020.”

As previously announced on October 16, 2019, Achillion entered into a definitive agreement to be acquired by Alexion Pharmaceuticals, Inc. (NASDAQ: ALXN). The initial consideration comprises $6.30 per share in cash for each share of Achillion common stock, and the transaction includes the potential for additional consideration in the form of non-tradeable contingent value rights, which will be paid to Achillion stockholders if certain clinical and regulatory milestones are achieved within specified periods.

Mr. Truitt continued, “We are making progress on the pending acquisition of Achillion by Alexion Pharmaceuticals, which is on track to close in the first half of 2020. Looking ahead to our future with Alexion, we expect the full potential for our portfolio of small-molecule complement inhibitors will be leveraged to accelerate our objective of bringing novel therapies to market faster to improve the lives of patients.”

Key Highlights and Development Updates:

Danicopan

• The U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for danicopan (ACH-4471) for treatment in combination with a C5 monoclonal antibody for patients with paroxysmal nocturnal hemoglobinuria (PNH) who are sub-optimal responders to a C5 inhibitor alone.  The FDA’s decision was based on interim data from the Company’s Phase 2 clinical trial assessing the safety and effectiveness of danicopan in combination with intravenous eculizumab. The top-line results from the Phase 2 clinical trial of danicopan in combination with eculizumab will be presented at the 61^st ASH Annual Meeting. Global regulatory discussions are ongoing with initiation of a Phase 3 program for danicopan planned for early 2020.
• The Company completed enrollment in the danicopan Phase 2 clinical trials for C3 glomerulopathy (C3G) and C3G/immune complex-mediated membrane glomerulonephritis (IC-MPGN). In the third quarter of 2019, three adolescent patients were enrolled in the 12-month single-arm open-label trial. A total of 35 patients have been enrolled in the two trials. Pending an analysis of the C3G data, the Company plans to meet with the FDA for an End-of-Phase 2 meeting and the European Medicines Agency (EMA) for scientific advice in 2020.
• Further evaluation of pharmacokinetic and pharmacodynamic biomarker data from the Phase 2 PNH monotherapy study for untreated PNH patients was accepted for poster presentation at the 61^st ASH Annual Meeting.

ACH-5228

• Results from the completed ACH-5228 Phase 1 multiple ascending dose study demonstrated that ACH-5228, when dosed 120 mg twice a day (BID) or higher, achieved near complete and sustained alternative pathway (AP) inhibition with a mean value of >95% at steady state concentrations as measured by AP Hemolysis and AP Wieslab assays. In the study, ACH-5228 was generally well-tolerated over the dose ranges tested, which included the doses expected to be evaluated in Phase 2 clinical trials. The Company plans to initiate Phase 2 development of ACH-5228 in PNH in early 2020.

Third-generation Factor D Inhibitors

• The Company continues to evaluate a series of third-generation factor D inhibitors, with unique pharmacokinetic attributes, which are believed to provide additional optionality and durability for our factor D development program. The Company plans to nominate one of its third-generation factor D inhibitors for clinical development in 2020.

Pending Acquisition of Achillion by Alexion

On October 15, 2019, Achillion entered into an Agreement and Plan of Merger, or Merger Agreement with Alexion Pharmaceuticals, Inc., a Delaware corporation, or Alexion, and Beagle Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Alexion, or Merger Sub.  Pursuant to the Merger Agreement, on the terms and subject to the conditions thereof, Merger Sub will merge with and into Achillion, which we refer to herein as the Merger, with Achillion surviving the Merger as a wholly owned subsidiary of Alexion. The initial consideration of approximately $930 million, or $6.30 per share of our common stock, will be funded by Alexion from cash on hand.  The transaction includes the potential for additional consideration in the form of non-tradeable contingent value rights, or CVRs, which will pay our shareholders up to $2.00 per share if certain clinical and regulatory milestones are achieved within specified periods. These include $1.00 per share for FDA approval of danicopan within fifty-four months of the closing date of the transaction and $1.00 per share for ACH-5228 Phase 3 initiation within four years of the closing date of the transaction. Alexion’s acquisition of the Company is subject to the approval of Company shareholders and satisfaction of customary closing conditions and approval from relevant regulatory agencies, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Subject to the satisfaction of these conditions, the parties expect the transaction to close in the first half of 2020. Additional information related to the Merger Agreement is set forth in our Current Report on Form 8-K filed with the SEC on October 16, 2019, which includes the full text of the Merger Agreement as Exhibit 2.1.

Third Quarter Financial Results

For the three months ended September 30, 2019, Achillion reported a net loss of $19.6 million compared with a net loss of $15.9 million during the same period of 2018. Research and development expenses were $15.0 million for the three months ended September 30, 2019, compared with $12.8 million for the same period of 2018. The increase for the three months ended September 30, 2019 was primarily due to increased manufacturing and formulation costs related to ACH-5228, partially offset by decreased clinical trial costs for danicopan.

For the three months ended September 30, 2019, general and administrative expenses were $6.1 million, compared with $4.4 million incurred during the same period in 2018. The increase for the three months ended September 30, 2019 was primarily due to increased legal fees combined with market research related professional fees.

Non-cash stock compensation expense totaled $1.7 million for the third quarter of 2019 as compared with $1.6 million for the third quarter of 2018 and is included in research and development expenses and general and administrative expenses.

Cash, cash equivalents and marketable securities as of September 30, 2019 was $229.0 million. The company expects year-end 2019 cash, cash equivalents and marketable securities of approximately $200 million.

Nine Month Financial Results

For the nine months ended September 30, 2019, Achillion reported a net loss of $58.0 million, compared to a net loss of $53.7 million in the same period in 2018. For the nine months ended September 30, 2019, research and development expenses totaled $45.7 million, compared with $37.9 million during the same period in 2018. The increase was primarily due to increased clinical trial costs related to danicopan and ACH-5228, combined with increased manufacturing and formulation costs related to danicopan and ACH-5228.

General and administrative expenses were $16.3 million for the nine months ended September 30, 2019, compared to $17.9 million in the same period in 2018. The decrease for the nine months ended September 30, 2019 was primarily due to decreased personnel costs and non-cash stock-based compensation charges related to the transition of our former chief executive officer.
Non-cash stock compensation expense totaled $4.9 million for the nine months ended September 30, 2019 as compared with $7.5 million for the same period in 2018 and is included in both research and development and general and administrative expenses.

About the Achillion Complement Factor D Portfolio
Achillion has leveraged its internal discovery capabilities and a novel complement-related platform to develop oral small molecule drug candidates that are inhibitors of complement factor D. Factor D is an essential serine protease involved in the alternative pathway (AP) of the complement system, a part of the innate immune system. Achillion's complement platform is focused on seeking to advance oral small molecules that inhibit the AP and can potentially be used in the treatment of immune-related diseases in which complement AP plays a critical role. Potential indications currently being evaluated for these compounds include paroxysmal nocturnal hemoglobinuria (PNH), C3 glomerulopathy (C3G), and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN).

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 significant unmet medical needs persist despite existing therapies. 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. In its efforts to advance its investigational product candidates into registrational clinical trials and commercialization, the Company plans to work closely with key stakeholders including patients, payors, regulators, and healthcare providers.
