NEWTON, Mass., Nov. 09, 2020 (GLOBE NEWSWIRE) -- Allena Pharmaceuticals (NASDAQ:ALNA), a late-stage, biopharmaceutical company dedicated to 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 third quarter ended September 30, 2020 and provided a business update.

“In recent months, we have continued to make progress across our portfolio. We are actively enrolling URIROX-2, our pivotal trial of reloxaliase for patients with EH. We also recently completed dosing in our Phase 1 trial of ALLN-346 and we remain on track to achieve all our expected clinical milestones,” said Louis Brenner, M.D, President and Chief Executive Officer of Allena Pharmaceuticals. “In addition, at the virtual ASN meeting, we presented an aggregate review of data generated across our clinical development program for reloxaliase, which highlight reloxaliase’s consistent, clinically meaningful impact on urinary oxalate excretion (UOx) and reinforce our conviction in its potential as a novel therapeutic that could change the treatment paradigm in EH. Following our strategic debt financing agreement with Pontifax, we are well-funded, with the capital and financial flexibility to advance our mission and deliver on the promise of oral enzyme therapeutics for people with rare and severe metabolic and kidney diseases.”

Allena Pharmaceuticals also announced today the resignation of Edward Wholihan, Chief Financial Officer, who will be stepping down for personal reasons. Mr. Wholihan will continue to serve in his current role as the Company conducts a search for his successor.

Dr. Brenner continued, “On behalf of my colleagues, I want to thank Ed for his dedicated leadership and business acumen, which have been instrumental in growing Allena into a publicly-traded, late-stage company. During his tenure, Ed has built a robust financial organization, providing an important foundation that has enabled investment across our portfolio.”

Recent Business Highlights and Upcoming Milestones:

Reloxaliase: Reloxaliase is a first-in-class, non-absorbed, orally administered enzyme for the treatment of severe hyperoxaluria. Allena is currently evaluating reloxaliase for patients with EH in URIROX-2, the second pivotal Phase 3 clinical trial in its URIROX program. Allena continues to expect the interim analysis from this trial in the first quarter of 2022 and to announce topline data, which are intended to support a potential Biologics License Application (BLA) submission, in the third quarter of 2022.

At the ASN meeting, held virtually in October 2020, Allena presented three posters, including an aggregate review of data from completed Phase 2 and 3 clinical trials of reloxaliase in EH and data from Study 206 in patients with EH and advanced chronic kidney disease (CKD). Data from these studies support that reloxaliase has been well-tolerated, with the potential to provide meaningful clinical benefit: across Phase 2 and 3 studies in EH, treatment with reloxaliase consistently reduced 24-hour UOx excretion in patients with EH, with reductions of 23 to 35 percent observed, and in Study 206, treatment with reloxaliase reduced both UOx and plasma oxalate (POx) excretion in patients with EH and CKD Stages 3-5. Also at ASN, Allena presented details on the study design for URIROX-2, the largest and most comprehensive randomized clinical trial to-date in EH.

ALLN-346: ALLN-346 is a first-in-class, orally administered, novel urate degrading enzyme that has been designed for activity and stability in the gastrointestinal tract for the treatment of hyperuricemia in patients with gout in the setting of advanced CKD.

In November 2020, Allena completed dosing of all subjects in its Phase 1 clinical trial of ALLN-346. This Phase 1 clinical trial is a randomized, double blind, placebo-controlled, single ascending dose study of orally administered ALLN-346 in approximately 24 healthy volunteers. The primary objective of the study is to assess safety and tolerability over 28 days. Initial data are expected in the fourth quarter of 2020.

Corporate:

• In September 2020, Allena entered into a $25 million loan and security agreement with Pontifax Medison Finance, the healthcare-dedicated venture and debt fund of the Pontifax life sciences funds. Under the terms of the agreement, Allena will have access to up to $25 million in convertible debt financing in three tranches; the Company drew the first tranche of $10 million upon closing. Additionally, both Pontifax and Allena have the option to convert the loan drawn under the first two tranches into shares of Allena’s common stock at a price of $4.10 per share, subject to certain conditions.
• In October 2020, Allena announced the appointment of Ann Miller, M.D., to its board of directors. Dr. Miller is an experienced industry executive, who has launched and grown multiple blockbuster products and built several leading franchises over the course of her career.

Third Quarter 2020 Financial Results:

• Cash Position: As of September 30, 2020, cash and cash equivalents were $30.1 million, as compared to $30.0 million as of December 31, 2019. The change in cash position was primarily due to gross proceeds of approximately $15.0 million received from the company’s June 2020 registered direct offering and gross proceeds of approximately $7.7 million received from the company’s July 2020 public underwritten offering, offset by cash used in operating activities.
• R&D Expenses: R&D expenses were $5.0 million for the third quarter of 2020, as compared to $10.8 million for the third quarter of 2019. The decrease was primarily due to a reduction of costs incurred for the reloxaliase program, including costs for the URIROX-1 and Study 206 trials, both of which were completed in the fourth quarter of 2019, and a reduction of costs incurred for the ALLN-346 program, including costs for formulation and development relating to its investigational new drug (IND) application incurred in the third quarter of 2019. The Company filed an IND for ALLN-346 with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019.
• G&A Expenses: G&A expenses were $3.0 million for the third quarter of 2020, as compared to $2.5 million for the third quarter of 2019. This increase was due primarily to increases in stock-based compensation and corporate directors and officers insurance costs.
• Net Loss: Net loss was $8.0 million for the third quarter of 2020, or a net loss per basic and diluted share of $0.22, as compared to a net loss of $13.3 million for the third quarter of 2019, or a net loss per basic and diluted share of $0.57. Contributing to the decrease in net loss per share was both a decrease in net loss for the quarter and an increase in the weighted average shares of common stock outstanding for the third quarter of 2020 compared to the weighted average shares outstanding for the third quarter of 2019, driven by the issuance of shares of common stock for the registered direct offering in June 2020 and the public underwritten offering in July 2020.

Financial Guidance:

Based on its current plans, Allena expects that its existing cash and cash equivalents, together with the funds available under its agreement with Pontifax, will be sufficient to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2021.
