Exhibit 99.1

Allena Pharmaceuticals Showcases Reloxaliase and Enteric Hyperoxaluria Program at OHF International Hyperoxaluria Workshop

NEWTON, Mass., June 21, 2019 — Allena Pharmaceuticals, Inc. (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 announced that it will present on its reloxaliase development program and the unmet need in patients with enteric hyperoxaluria (EH) in four sessions at the Oxalosis & Hyperoxaluria Foundation (OHF) International Hyperoxaluria Workshop, to be held June 21-22, 2019 in Boston, MA. The OHF International Hyperoxaluria Workshop is the largest gathering of hyperoxaluria patients, disease advocates and thought leaders worldwide.

“Allena’s strong presence at the OHF International Hyperoxaluria Workshop highlights our progress in developing reloxaliase as a potential first-in-class therapy for patients suffering from enteric hyperoxaluria, as well as our ongoing efforts to work with advocacy groups and treating physicians to better characterize the progression of this debilitating disease,” said Louis Brenner, M.D., President and Chief Executive Officer of Allena Pharmaceuticals. “We are encouraged by the growing awareness of severe oxalate disorders and the increasingly active community focused on treating patients with enteric hyperoxaluria. Our network of investigators and patient advocates has supported us throughout the development of reloxaliase. We look forward to sharing data from our pivotal URIROX-1 Phase 3 clinical trial in the second half of the year and to laying the foundation in support of the future launch of reloxaliase.”

The four presentations are summarized below:

In the session on enteric hyperoxaluria, Allena’s Chief Medical Officer, Dr. Annamaria Kausz, will present data on the burden of disease and the significant unmet need in this under-recognized patient population. In addition to recurrent kidney stones, EH patients can also suffer from progressive loss of kidney function and end stage renal disease. A recent review on clinical outcomes in EH patients with oxalate nephropathy found that renal replacement therapy was required in > 50% of patients.¹    Additionally, there is increasing awareness of the association between excess urinary oxalate excretion and the risk of chronic kidney disease progression.²

In the session on the industry pipeline, Allena’s President and Chief Executive Officer, Dr. Louis Brenner, will present an overview of the development program for reloxaliase, including the ongoing URIROX Phase 3 program and Study 206. Allena’s URIROX program consists of two pivotal Phase 3 trials, URIROX-1 and URIROX-2, which are designed to evaluate the safety and efficacy of reloxaliase in patients with EH. These trials represent the largest studies conducted to-date in patients with EH.

In the poster session, a case series of the first four subjects with EH and advanced CKD treated with reloxaliase in Study 206 will be presented. Study 206 is a multi-center, open-label, single-arm Phase 2 basket study, designed to evaluate reloxaliase in adult and pediatric patients suffering from the progression of enteric hyperoxaluria with advanced chronic kidney disease (CKD) or primary hyperoxaluria (PH), both of which can lead to systemic oxalosis.

In the family and patient advocacy panel, Allena will join other biotechnology companies developing potential therapies that target the common enemy of excess oxalate, which can lead to severe disease in high risk patient populations.

About Reloxaliase

Reloxaliase is an orally-administered, recombinant oxalate-degrading enzyme that is being developed for the treatment of severe hyperoxaluria. Reloxaliase targets oxalate in the GI tract in an effort to reduce the burden of both dietary and endogenously-produced oxalate. Reloxaliase has the potential to decrease the oxalate available systemically for deposition as calcium oxalate crystals or stones in the kidneys, as well as reduce long-term kidney complications. In addition, reloxaliase has been granted separate orphan drug designations by the U.S. Food and Drug Administration for the treatment of primary hyperoxaluria and for the treatment of pediatric hyperoxaluria. The European Commission has granted orphan drug designation for reloxaliase for the treatment of primary hyperoxaluria.

About Pivotal Phase 3 URIROX Program

Allena’s URIROX program consists of two pivotal Phase 3 trials, URIROX-1 and URIROX-2, which are designed to evaluate the safety and efficacy of reloxaliase in patients with enteric hyperoxaluria.

URIROX-1 is a multicenter, global, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of reloxaliase in an expected 124 patients for a four-week treatment period. Patients will be randomized 1:1 to reloxaliase vs. placebo and will take 284 mg (equivalent to 7,500 units) of reloxaliase or placebo with each meal or snack up to five times per day, consistent with the eating patterns of patients with enteric hyperoxaluria. Allena expects to report topline data from URIROX-1 in the second half of 2019.

URIROX-2 is a multicenter, global, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of reloxaliase in patients with enteric hyperoxaluria, over a minimum treatment period of two years. The trial is designed to enroll 400 patients with 24-hour urine oxalate (UOx) excretion greater than or equal to 50 mg and a history of kidney stones, and will include patients with normal kidney function as well as chronic kidney disease.

The primary efficacy endpoint of URIROX-2 is the percent change from baseline in 24-hour UOx excretion during Weeks 1-4, comparing reduction in the average UOx excretion across Weeks 1-4 with reloxaliase to placebo, the same primary endpoint as URIROX-1. Secondary endpoints in URIROX-2 include the proportion of subjects with a ³ 20% reduction from baseline in 24-hour UOx excretion during Weeks 1-4 and percent change from baseline in 24-hour UOx excretion during Weeks 16 to 24. The primary long-term efficacy endpoint to confirm clinical benefit is the proportion of subjects with kidney stone disease progression, defined as a composite of either symptomatic kidney stones or finding of new or enlarged kidney stones using imaging, over a minimum treatment period of two years. Secondary long-term efficacy endpoints to confirm clinical benefit include change in eGFR from baseline and emergency room visits, hospitalizations or procedures for the management of kidney stones.

In January 2019, Allena announced that it reached alignment with the U.S. Food and Drug Administration (FDA) on both the design of URIROX-2 and its strategy to pursue a Biologics License Application (BLA) submission for reloxaliase in patients with enteric hyperoxaluria using the accelerated approval regulatory pathway.

In March 2019, Allena announced an agreement with the Duke Clinical Research Institute (DCRI), a leading academic research institute within Duke University School of Medicine, to establish and lead an Academic Coordinating Center (ACC) in support of the URIROX-2 Phase 3 clinical trial and preparation for the potential launch of reloxaliase.

About Study 206

Study 206 is a multi-center, open-label, single-arm Phase 2 basket study, designed to evaluate reloxaliase in adult and pediatric patients suffering from the progression of EH with advanced CKD or PH, both of which can lead to systemic oxalosis. The clinical trial is designed to enroll between 15 and 20 patients aged 12 and older. Patients orally administer 7,500 units of reloxaliase with each meal or snack five times a day, for 12 consecutive weeks. The primary endpoints of the trial are change from baseline in 24-hour UOx excretion and POx levels.

This basket study is seeking to identify an efficacy signal in several high risk patient populations including enteric hyperoxaluria patients with CKD, kidney transplantation or dialysis dependence or patients with primary hyperoxaluria types 1, 2 or 3. UOx is being collected for patients who are not on dialysis. Data has been released on the first seven patients from the study. This includes the first four EH patients who demonstrated plasma oxalate (POx) reductions of 28% and 16%, compared to baseline, in the two patients not on dialysis, and 49% and 45% in the two patients on dialysis. In addition, for the two patients not on dialysis, 24 hour UOx excretion was reduced by 29% and 42%. The summary data showed a range of POx reduction from 16% to 49% with an average reduction of 35%, compared to baseline. This summary POx data corrects an inadvertent error in a press release

issued on June 4^th, 2019. The individual patient data that was also publicly released on June 4^th, 2019 is correct and unchanged. Three patients with PH type 2 and PH type 3 with preserved renal function were treated. These are the first patients with any form of PH treated with reloxaliase. One patient had a > 20% mean reduction in UOx excretion while the other two patients did not show a response to reloxaliase.

Based on the treatment effect observed in these four EH patients, coupled with the unmet need and high risk of morbidity and mortality in EH patients with advanced CKD, Allena intends to focus further enrollment in Study 206 on patients with EH and CKD, kidney transplantation or dialysis dependence and patients with PH and compromised renal function. Allena expects to announce topline results from the trial in the second half of 2019.

Exhibit 99.2

Allena Pharmaceuticals Announces Interim Results from Study 206 of Reloxaliase in High Risk Patients with

Advanced Oxalate Disorders

— Substantial Treatment Effect Observed in Patients with Enteric Hyperoxaluria, Including Robust Reductions in

Both Urine and Plasma Oxalate –

— Reloxaliase Well-Tolerated Over 12 Weeks of Dosing —

— Detailed Results to be Presented at OHF International Hyperoxaluria Workshop in June 2019 —

NEWTON, Mass., June 4, 2019 — Allena Pharmaceuticals, Inc. (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 announced interim data from Study 206, its Phase 2 basket clinical trial of reloxaliase, an orally-administered, recombinant oxalate-degrading enzyme. Study 206 includes adult and pediatric patients suffering from the progression of primary hyperoxaluria (PH) or enteric hyperoxaluria (EH) with advanced chronic kidney disease (CKD), both of which can lead to systemic oxalosis, a potentially life-threating condition. Consistent with Allena’s prior clinical experience, EH patients treated with reloxaliase in Study 206 demonstrated a substantial treatment effect. This includes EH patients with advanced CKD, a patient population not previously treated with reloxaliase, who showed reductions in urine oxalate (UOx) and plasma oxalate (POx). Allena plans to present detailed results at the OHF International Hyperoxaluria Workshop, June 21-22, 2019 in Boston, MA.

“We are pleased to see a robust response to reloxaliase in EH patients suffering from advanced stages of the disease. We believe this reflects reloxaliase’s activity and novel mechanism of action of degrading oxalate within the GI tract, which is well-targeted to treat excess oxalate absorption driven by an underlying GI disorder. The potential to alleviate the high oxalate burden on these patients is very encouraging,” said Louis Brenner, M.D., President and Chief Executive Officer of Allena Pharmaceuticals. “To our knowledge, this is a first demonstration of a specific pharmacologic therapy leading to reduction in plasma oxalate and urinary oxalate levels in patients with EH and decreased kidney function, which represents a significant advancement for the field and especially for patients with systemic oxalosis. These results advance our efforts to develop reloxaliase as a potential first-in-class therapy for patients with enteric hyperoxaluria, and we look forward to additional data from Study 206, as well as topline data from our pivotal Phase 3 URIROX-1 trial, anticipated in the second half of the year.”

Interim Data from Study 206

Study 206 is a multi-center, open-label, single-arm Phase 2 clinical trial designed to enroll between 15 and 20 patients in the United States and Europe aged 12 and older. Patients orally administer 7,500 units of reloxaliase with each meal or snack five times a day, for 12 consecutive weeks. The primary endpoints of the trial are change from baseline in 24-hour UOx excretion and POx levels. UOx was collected for patients who are not on dialysis.

The first seven patients have completed treatment, including one EH patient with advanced CKD, one EH patient with a functioning kidney transplant and two patients with EH who are on dialysis. Three patients had PH and preserved renal function.

• All four patients with EH experienced a reduction in POx, with an average reduction of 35% compared to baseline (range 16% to 49%). The two patients not on dialysis also experienced reductions in UOx of 29% and 42%, respectively. The treatment effect observed in these EH patients supports a continued focus on treating EH patients with CKD, kidney transplantation or dialysis dependence in an effort to reduce further oxalate damage.

• Three patients with PH type 2 or PH type 3 with preserved renal function were treated. These are the first patients with any form of PH treated with reloxaliase. One patient had a >20% mean reduction in UOx excretion, while the other two patients did not show a response to reloxaliase. Allena intends to narrow its further evaluation of reloxaliase in PH to patients with compromised renal function where the GI mechanism of action may play a more important role.

• This trial encompasses the longest reloxaliase treatment duration thus far. All patient populations are being treated for three months with more frequent dosing of reloxaliase than the Company’s prior Phase 2 studies (7,500 units of reloxaliase, five times per day). Average patient dosing compliance was greater than 90%. Treatment with reloxaliase was well-tolerated in all patient populations, with no reported treatment-related serious adverse events.

“I am extremely encouraged by the interim data from Study 206. People living with EH and significant renal compromise suffer from underlying GI conditions, which perpetuate a vicious and potentially fatal cycle of kidney damage, transplantation and return to dialysis, and there are no approved therapies available with which to treat them,” said Felix Knauf, Professor of Nephrology, Charite’ University Hospital Berlin, Germany and Assistant Professor Adjunct at Yale University. “Though early, these results suggest that reloxaliase may offer a well-tolerated and easily-administered new medicine for these patients. By reducing both UOx and POx levels, reloxaliase has the potential to improve renal outcomes by lessening the likelihood that patients will develop calcium oxalate crystal deposition in their kidneys or other organs. I am eager to work with Allena to enroll additional patients in this study, as we continue to evaluate potential near- and long-term clinical benefits of reloxaliase treatment.”

About Hyperoxaluria and Systemic Oxalosis

Hyperoxaluria is a metabolic disorder characterized by elevated urinary oxalate levels that may be due to either overproduction of oxalate by the liver from a genetic defect, known as primary hyperoxaluria, or from the excess absorption of oxalate from the diet, known as secondary hyperoxaluria. Secondary hyperoxaluria is further characterized either as enteric, resulting from a chronic and unremediable underlying GI disorder, or idiopathic, meaning the underlying cause is unknown. Systemic oxalosis occurs when excess oxalate is present throughout the body including the blood, kidney, bones, joints, eyes and heart. People living with systemic oxalosis have varying degrees of renal impairment including kidney stones, nephrocalcinosis, chronic kidney disease, and end-stage renal disease.

Reloxaliase is an orally-administered, recombinant oxalate-degrading enzyme that is being developed for the treatment of severe hyperoxaluria. Reloxaliase targets oxalate in the GI tract in an effort to reduce the burden of both dietary and endogenously-produced oxalate. Reloxaliase has the potential to decrease the oxalate available systemically for deposition as calcium oxalate crystals or stones in the kidneys, as well as reduce long-term kidney complications. Reloxaliase is being evaluated in the ongoing pivotal Phase 3 URIROX-1 and URIROX-2 trials for patients with enteric hyperoxaluria and the ongoing Phase 2 basket trial for adult and pediatric patients suffering from primary hyperoxaluria or enteric hyperoxaluria with advanced chronic kidney disease. In addition, reloxaliase has been granted separate orphan drug designations by the U.S. Food and Drug Administration for the treatment of primary hyperoxaluria and for the treatment of pediatric hyperoxaluria. The European Commission has granted orphan drug designation for reloxaliase for the treatment of primary hyperoxaluria.
