Registered direct offering completed in July with gross proceeds of $28.0 million

NEWTON, Mass., August 10, 2021 - Allena Pharmaceuticals, Inc. (NASDAQ: ALNA) ('Allena' or the 'Company'), a late-stage biopharmaceutical company deploying its novel oral biologic platform to discover, develop and commercialize first-in-class, oral enzyme therapeutics for difficult-to-treat metabolic diseases, today reported financial results for the second quarter ended June 30, 2021 and highlighted recent corporate progress.

'This is an exciting time to advance our first-in-class, novel oral biologic platform,' commented Louis Brenner, M.D., President and Chief Executive Officer of Allena. 'We have continued to progress our two clinical programs with the goal of addressing therapeutic needs for patients with rare and severe metabolic conditions for which current treatment options are limited. For our reloxaliase program, we recently announced that we expect to conduct the first interim analysis early next year for patients enrolled in URIROX-2 through November of this year. We believe that this will provide meaningful and timely feedback for the conduct and ultimate completion of the adaptive design trial in patients with enteric hyperoxaluria.'

Dr. Brenner continued, 'In addition, after successfully completing two Phase 1 safety studies, we are focused on advancing ALLN-346 through Phase 2a studies as a potential treatment for patients with gout in the setting of chronic kidney disease. We expect to accelerate the development of ALLN-346, which has the potential to address an unmet need for gout patients as an alternative tocurrently available agents that are either dose-limited or contraindicated in patients with gout and chronic kidney disease due to safety and tolerability concerns. We look forward to reporting initial data from the Phase 2a program later this year.'

Recent Corporate Developments

•

Updated Plan and Earlier Timing for First Interim Analysis of the URIROX-2 Phase 3 Trial

In July, the Company announced an updated plan and timing related to the first interim analysis of the URIROX-2 Phase 3 trial investigating reloxaliase, a first-in-class, orally administered, non-absorbed enzyme in development for enteric hyperoxaluria. Reloxaliase is being studied in the adaptive-design URIROX-2 trial, the second of two pivotal Phase 3 clinical trials in the reloxaliase program.

As part of the URIROX-2 adaptive design, the Company had previously planned to conduct the first interim analysis after 130 subjects had been treated for at least six months and had estimated the timing of this analysis to be in the second or third quarter of 2022. Given the adverse impact of the COVID-19 global pandemic on the rate of patient enrollment in this global study, and considering that enrollment in the study began in early 2019, the Company announced that it had modified its plans and now expects to conduct the first interim analysis, which will include all patients who are enrolled in the trial by the end of November 2021 (currently expected to be approximately 80 patients), during the first quarter of 2022.

The revised interim analysis, which will be conducted by an independent data monitoring committee, will assess whether the study continues to be adequately powered to evaluate efficacy against the primary endpoint, the change in urinary oxalate levels during weeks 1-4 versus baseline, with the planned enrollment of 200 subjects, or whether the study size should be increased. Any adjustment in study size would be designed to ensure that the statistical power of the study remains sufficiently robust. As previously planned, the interim analysis will also include an assessment of futility with respect to the primary endpoint.

•

Initiation of Phase 2a Program for ALLN-346

In July, Allena announced that it had completed a Phase 1b multiple ascending dose study of ALLN-346, its first-in-class, non-absorbed, orally administered enzyme in development for the treatment of hyperuricemia and gout in the setting of advanced chronic kidney disease. The Company also recently initiated dosing for the ALLN-346 201 Trial, the first of two planned, randomized, double-blind, placebo-controlled Phase 2a trials designed to assess initial bioactivity data and additional safety data for ALLN-346. Initial results from the Phase 2a program are expected during the fourth quarter of 2021.

KOL Webinar Hosted by Allena Highlighted Unmet Need in Gout and Potential for ALLN-346

In June, the Company highlighted the treatment paradigms and also limitations of existing gout therapies in a webinar hosted with key opinion leader (KOL), Robert Terkeltaub, M.D., Professor of Medicine at the University of California San Diego School of Medicine and Section Chief of Rheumatology at the Veterans Administration Medical Center in San Diego (a replay of the webinar can be found here). Managing gout in the setting of advanced chronic kidney disease remains a significant challenge for clinicians because currently available agents are either dose-limited or contraindicated in these patients. There are approximately 500,000 patients with gout and advanced chronic kidney disease in the United States.
