CAMBRIDGE, Mass.--(BUSINESS WIRE)--$AMLX--Amylyx Pharmaceuticals, Inc. (Nasdaq: AMLX) (“Amylyx” or the “Company”) today reported financial results for the second quarter ended June 30, 2023.

“We made strong and steady progress on our commercial launches in the second quarter, supporting people living with ALS with increased access to RELYVRIO/ALBRIOZA in the U.S. and Canada,” said Joshua Cohen and Justin Klee, co-CEOs of Amylyx. “We continued to execute on our long-term R&D strategy, which includes exploring the full potential of our therapy in other neurodegenerative diseases. We are on track to initiate our global Phase 3 ORION trial of AMX0035 for the treatment of progressive supranuclear palsy later this year. Our Phase 2 HELIOS study of AMX0035 for the treatment of Wolfram syndrome is enrolling participants, and we continue to expect topline results next year.”

Second Quarter 2023 and Recent Business Highlights:

• Commercial launches of RELYVRIO® in the U.S. and ALBRIOZA™ in Canada, also known as AMX0035, continued to progress. Net product revenue for the three months ended June 30, 2023 was $98.2 million, compared to net product revenue of $71.4 million for the three months ended March 31, 2023.

• Five Canadian provinces announced public reimbursement of ALBRIOZA. Following the completion of the Company’s negotiation process with the pan-Canadian Pharmaceutical Alliance, the Company entered into a Product Listing Agreement with Ontario for the public reimbursement of ALBRIOZA through the Ontario Drug Benefit Program, effective June 22, 2023. Since June, the provinces of Quebec, British Columbia, New Brunswick, and Alberta committed to offering public coverage for ALBRIOZA by listing the therapy on their drug benefit formularies. Amylyx expects ALBRIOZA coverage to be in place for the vast majority of publicly insured lives in Canada by the end of August. By the end of 2023, the Company expects to finalize and sign product listing agreements with the remaining federal, provincial, and territorial public drug plans that have yet to include ALBRIOZA on their formulary.

• Plans underway to initiate a global, pivotal Phase 3 trial of AMX0035 for the treatment of progressive supranuclear palsy (PSP). PSP is a rare, progressive neurological disorder that affects body movements, walking and balance, and eye movement and is typically fatal within 6 to 8 years. There are currently no approved disease-modifying therapies for the treatment of PSP, and the disease affects seven in 100,000 people worldwide. PSP is characterized by widespread neurodegeneration associated with tau protein deposition in subcortical regions of the brain. Based on biomarker analyses from the Phase 2 PEGASUS trial of AMX0035 in Alzheimer’s disease and preclinical data, AMX0035 was shown to significantly lower levels of tau and other markers of neurodegeneration. The Company plans to initiate the pivotal Phase 3 ORION trial by year-end and intends to enroll approximately 600 adult participants across the U.S., Canada, Europe, and Japan.

• In July, the Company hosted a virtual webcast with Prof. Dr. Günter Höglinger to discuss the treatment landscape for people living with PSP, the scientific rationale for studying AMX0035 in PSP, and the Company’s clinical development plans. Prof. Dr. Höglinger, a leading expert in PSP, serves as the Director of the Department of Neurology at LMU Hospital, Ludwig-Maximilians-University in Munich, Germany and is the primary investigator for the Phase 3 ORION trial. A replay is available at https://investors.amylyx.com.

• Marketing Authorisation Application (MAA) for AMX0035 for the treatment of ALS under review with the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP). Amylyx received a negative opinion from the CHMP in June and requested a formal re-examination of the MAA in July. CHMP is re-examining its initial opinion on the current application for conditional marketing authorisation of AMX0035. The re-examination procedure is an approximately four-month process, which includes the appointment of a different rapporteur and co-rapporteur from the initial evaluation. At the end of the re-examination, the CHMP will adopt a final opinion, which is expected in fall 2023.

Financial Results for the Second Quarter Ended June 30, 2023

For the three months ended June 30, 2023, net product revenue was $98.2 million, and cost of sales were $5.6 million. Both net product revenue and cost of sales during the period were primarily attributable to sales of RELYVRIO in the U.S. and ALBRIOZA in Canada. There were no product revenues or cost of sales for the comparable period in 2022.

Research and development expenses were $29.0 million for the three months ended June 30, 2023, compared to $24.3 million for the same period in 2022. The increase was primarily driven by an increase in personnel-related expenses due to added headcount to support research and development efforts and an increase in spending on AMX0035 for the treatment of PSP to support the initiation of the Phase 3 ORION trial.

Selling, general and administrative expenses were $43.4 million for the three months ended June 30, 2023, compared to $30.0 million for the same period in 2022. The increase was primarily driven by higher personnel-related expenses due to added headcount to support our launch, commercialization initiatives, and operations as a public company.

Net income for the three months ended June 30, 2023 was $22.1 million, or $0.31 on a fully diluted per share basis, compared to a net loss of $54.1 million, or $0.93 on a fully diluted per share basis for the same period in 2022.

Cash, cash equivalents, and short-term investments were $357.3 million at June 30, 2023, compared to $345.7 million at March 31, 2023.

About RELYVRIO^®/ALBRIOZA^™ /AMX0035

RELYVRIO® (also known as AMX0035), an oral, fixed-dose combination of sodium phenylbutyrate and taurursodiol (known as ursodoxicoltaurine outside of the U.S.), is approved to treat amyotrophic lateral sclerosis (ALS) in adults in the U.S. and approved with conditions as ALBRIOZA™ for the treatment of ALS in Canada. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) is re-examining its initial opinion on the current application for conditional marketing authorisation of AMX0035, under the trade name ALBRIOZA®, for the treatment of ALS in the European Union. AMX0035 is being explored for the potential treatment of other neurodegenerative diseases. The formulation of RELYVRIO, ALBRIOZA, and AMX0035 are identical.

RELYVRIO® (sodium phenylbutyrate and taurursodiol) Safety Information for United States

WARNINGS AND PRECAUTIONS

Risk in Patients with Enterohepatic Circulation Disorders, Pancreatic Disorders, or Intestinal Disorders

RELYVRIO contains taurursodiol, which is a bile acid. In patients with disorders that interfere with bile acid circulation, there may be an increased risk for worsening diarrhea, and patients should be monitored appropriately for this adverse reaction. Pancreatic insufficiency, intestinal malabsorption, or intestinal diseases that may alter the concentration of bile acids may also lead to decreased absorption of either of the components of RELYVRIO. Because different enterohepatic circulation, pancreatic, and intestinal disorders have varying degrees of severity, consider consulting with a specialist. Patients with disorders of enterohepatic circulation (e.g., biliary infection, active cholecystitis), severe pancreatic disorders (e.g., pancreatitis), and intestinal disorders that may alter concentrations of bile acids (e.g., ileal resection, regional ileitis) were excluded from the study; therefore, there is no clinical experience in these conditions.

Use in Patients Sensitive to High Sodium Intake

RELYVRIO has a high salt content. Each initial daily dosage of 1 packet contains 464 mg of sodium; each maintenance dosage of 2 packets daily contains 928 mg of sodium. In patients sensitive to salt intake (e.g., those with heart failure, hypertension, or renal impairment), consider the amount of daily sodium intake in each dose of RELYVRIO and monitor appropriately.

ADVERSE REACTIONS

The most common adverse reactions (at least 15% and at least 5% greater than placebo) with RELYVRIO were diarrhea, abdominal pain, nausea, and upper respiratory tract infection. Gastrointestinal-related adverse reactions occurred throughout the study but were more frequent during the first 3 weeks of treatment.
