ALNA Allena Pharmaceuticals Inc

Allena Pharmaceuticals (NASDAQ:ALNA), a late-stage biopharmaceutical company dedicated to discovering, developing and commercializing first-in-class oral enzyme therapeutics to treat patients with rare and severe metabolic and kidney disorders, today reported financial results for the first quarter ended March 31, 2021 and provided a business update.

“We are encouraged by the global relaunch of URIROX-2 and the lessening of the effects of the pandemic on the trial, as Q1 2021 was the most active quarter to date in terms of new site openings, subject screening and enrollment," said Louis Brenner, M.D., President and Chief Executive Officer of Allena Pharmaceuticals. "Additionally, we continue to advance the development of ALLN-346, our second novel oral biologic, for the treatment of gout. We recently initiated our Phase 1 multiple-ascending dose study in healthy volunteers and we remain on track to initiate a Phase 2a program in patients with hyperuricemia during the third quarter. Because many of the currently available agents are either dose-limited or contraindicated in patients with gout and chronic kidney disease due to safety and tolerability concerns, we believe there is a substantial unmet medical need for a new therapy for these patients. We look forward to sharing additional detail on our clinical development program and the market opportunity for ALLN-346 at our key opinion leader webinar in June."

Allena today announced plans to host a key opinion leader webinar focused on the unmet need in gout in the setting of chronic kidney disease (CKD) and the potential for ALLN-346 as a first-in-class therapy. The webinar will be held virtually on June 16, 2021 beginning at 12:00 p.m. ET. Scheduled to speak at the event is Robert Terkeltaub, M.D., Professor of Medicine, UC San Diego Medical School. Additionally, Allena management will provide an overview of the market opportunity in gout and the ongoing clinical development program for ALLN-346. A live audio webcast of the event will be available under “Events and Presentations” in the Investors section of the Company’s website at www.allenapharma.com. More details for the event will be forthcoming.

Clinical-Stage Product Candidate Updates

Reloxaliase: Novel oral biologic for enteric hyperoxaluria

Reloxaliase is a first-in-class, non-absorbed, orally administered enzyme for the treatment of enteric hyperoxaluria, a metabolic disorder characterized by high levels of urinary oxalate, which can lead to kidney stone disease and chronic kidney disease. There are currently no approved therapies for this disorder, which affects approximately 250,000 patients in the United States. Reloxaliase exerts its effect by breaking down oxalate in the gastrointestinal (GI) tract, reducing the absorption of dietary oxalate. Allena previously completed the URIROX-1 trial, the first of two pivotal Phase 3 clinical trials of reloxaliase, which demonstrated a statistically significant reduction in urinary oxalate levels, the primary endpoint of the study.

Allena is currently studying reloxaliase in the URIROX-2 trial, the second pivotal Phase 3 clinical trial in its URIROX program, with planned enrollment of 200 patients. The Company plans to conduct an interim analysis after 130 patients have been enrolled in the study for six months, currently expected to occur during the second or third quarter of 2022, with topline data becoming available approximately six months later. The U.S. Food and Drug Administration (FDA) has advised Allena that it agrees with the Company's strategy of pursuing a potential Biologics License Application (BLA) submission for reloxaliase based upon data from its URIROX program, including the completed URIROX-1 and ongoing URIROX-2 trials, using the accelerated approval regulatory pathway. To support potential accelerated approval, patients will also continue to be followed for a minimum of two years to confirm clinical benefit, including the ability of reloxaliase to reduce the incidence and severity of kidney stone disease and renal impairment.

ALLN-346: Novel oral biologic for hyperuricemia and gout

ALLN-346 is a first-in-class, non-absorbed, orally administered enzyme for the treatment of hyperuricemia and gout, a metabolic disorder characterized by high systemic levels of uric acid that can lead to several complications, including arthritis and chronic kidney disease. Although there are several currently available medicines for the treatment of gout, managing gout in the setting of chronic kidney disease remains a significant challenge for clinicians because many of these agents are either dose-limited or contraindicated in these patients. There are approximately 375,000 patients with uncontrolled gout and stage 3 - 5 chronic kidney disease in the United States. ALLN-346 is designed to exert its effect by breaking down urate in the GI tract, which is expected to lead to a concomitant reduction in urine and serum urate levels. During the fourth quarter of 2020, Allena completed a Phase 1 single ascending dose study of ALLN-346 in healthy volunteers, which demonstrated no safety or tolerability concerns. In addition, an immunoassay of plasma samples demonstrated that ALLN-346 was not absorbed systemically.

The Company is currently dosing healthy volunteers in a double-blind, placebo-controlled, Phase 1b multiple-ascending dose (MAD) study. The study is designed to enroll approximately 18 healthy volunteers, randomized 2:1 to receive ALLN-346 or placebo. Subjects will be treated in one of two ascending dose cohorts for seven days, and will receive either three capsules thrice daily (TID) for a total of nine capsules, or five capsules TID, for a total of 15 capsules. The primary endpoint of the study is an assessment of safety and tolerability. Allena expects to report initial clinical data in the third quarter of 2021. Additional information about the trial is available at www.clinicaltrials.gov (NCT04829435).

Additionally, pending feedback from the FDA, a Phase 2a program is planned for the second half of 2021, with initial efficacy data expected during the fourth quarter. The Company intends to focus its development program for ALLN-346 on the significant population of patients with hyperuricemia and gout who also suffer from CKD, for whom many of the currently available therapeutics are either dose-limited or contraindicated due to safety and tolerability concerns.

Corporate Update

Appointment of Mark Fitzpatrick to Board of Directors

In April 2021, Allena announced the appointment of Mark J. Fitzpatrick to its board of directors. Mr. Fitzpatrick brings over 30 years of operational and financial management experience to Allena, including extensive experience working with advanced clinical and commercial stage rare disease companies. Mr. Fitzpatrick is expected to become chairman of Allena's Audit Committee at the time of the Company's annual meeting of shareholders.

First Quarter 2021 Financial Results:

• R&D Expenses: R&D expense was $7.9 million for the first quarter of 2021 as compared to $4.6 million for the first quarter of 2020. The increase was primarily due to increased costs incurred for the reloxaliase program, primarily related to the URIROX-2 trial, along with an increase in costs associated with the ALLN-346 program.
• G&A Expenses: G&A expense was $3.6 million for the first quarter of 2021 as compared to $2.9 million for the first quarter of 2020. The increase was primarily due to an increase in the number of employees and insurance costs.
• Net Loss: Primarily reflecting the factors noted above, net loss was $11.6 million for the first quarter of 2021, as compared to a net loss of $7.6 million for the first quarter of 2020. 
• Cash Position: The cash balance as of March 31, 2021 was $36.3 million. The Company raised $11.7 million of net proceeds during the first quarter from sales of its common stock through an at-the-market (ATM) equity issuance facility.
