LEXINGTON, Mass.--(BUSINESS WIRE)-- Dicerna Pharmaceuticals (Nasdaq: DRNA) (the “Company” or “Dicerna”), a leading developer of investigational ribonucleic acid interference (RNAi) therapeutics, today reported its financial results for the quarter ended June 30, 2021 and provided a corporate update.

“We have seen significant progress across our core and collaborative pipelines over the past few months, including the achievement of a major milestone in our maturation as a company,” said Douglas Fambrough, Ph.D., President and Chief Executive Officer at Dicerna. “Specifically, our recently announced PHYOX™2 results represent our first positive pivotal trial readout. PHYOX2 generated robust data, meeting the primary and key secondary efficacy endpoints, and nedosiran was generally well tolerated in the trial. Based on these results, we believe nedosiran has significant potential as a treatment for patients with PH1, and we are on course to submit a New Drug Application to the FDA for the treatment of PH1 in the fourth quarter. Notably, these positive results reflect broadly on our GalXC™ RNAi platform and bode well for our additional proprietary and partnered programs.

“As positive as these results are for PH1, the inconsistent data seen specifically in participants with PH2 have led us to make the strategic decision not to move forward with our plan to build Dicerna into a fully integrated commercial enterprise to support nedosiran,” Dr. Fambrough continued. “Instead, we intend to pursue commercial out-licensing opportunities to help ensure global access to nedosiran, subject to necessary approvals. This approach will allow us to deploy our capital and talent on our discovery and development pipeline efforts with our GalXC and GalXC-Plus™ RNAi investigational therapeutics for ourselves and our partners. With these strategic adjustments focused on our core strengths, we can extend our cash runway into 2025.”

Recent Updates

• Positive Top-Line Data From Pivotal PHYOX2 Clinical Trial of Nedosiran for Primary Hyperoxaluria (PH). Dicerna announced in August positive top-line results from the pivotal PHYOX2 clinical trial of nedosiran. Nedosiran achieved the primary endpoint in the PHYOX2 trial, demonstrating a statistically significant reduction from baseline in urinary oxalate (Uox) excretion compared to placebo (p<0.0001). The study also achieved the key secondary endpoint, with a significantly higher proportion of patients given nedosiran achieving and sustaining normal or near-normal Uox at two or more consecutive visits after Day 90 compared to placebo (p=0.0025). Uox reductions were significant in participants with PH1 while participants with PH2 (5 nedosiran and 1 placebo) showed inconsistent results in this trial. Nedosiran was generally well tolerated in the study with an overall adverse event (AE) profile consistent with previously reported data from PHYOX trials. The Company expects the results from the PHYOX2 trial to support marketing authorization applications for the treatment of PH1 in the U.S. and other major markets and intends to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2021.

• Announced Clearance of Investigational New Drug (IND) Application for DCR-AUD for the Treatment of Alcohol Use Disorder (AUD). In July 2021, Dicerna announced U.S. Food and Drug Administration (FDA) clearance of the IND application for DCR-AUD, the Company’s investigational GalXC RNAi candidate for the treatment of AUD. Dicerna plans to initiate a Phase 1 trial in the third quarter of 2021 to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending doses of DCR-AUD in healthy volunteers.

• Reported Interim Data From Phase 1 Trial of Belcesiran. In July 2021, Dicerna reported interim data from the Company’s Phase 1 trial of belcesiran, a GalXC RNAi therapeutic candidate in development for the treatment of alpha-1 antitrypsin (AAT) deficiency-associated liver disease (AATLD). The trial is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of belcesiran in healthy volunteers. Data from this interim analysis of the four completed active-treatment dose cohorts (0.1, 1.0, 3.0 and 6.0 mg/kg) showed dose-dependent reductions in serum AAT with administration of a single dose of belcesiran. In this analysis, belcesiran was found to have an acceptable safety profile and was generally well tolerated. The final 12.0 mg/kg dose cohort in this trial is ongoing, and the Company plans to present additional data from this study at a medical congress in 2021, subject to abstract acceptance.

• Initiated ESTRELLA Phase 2 Clinical Trial Patient Dosing of Belcesiran for the Treatment of AATLD. In June 2021, Dicerna announced initiation of the Company’s ESTRELLA Phase 2 trial for belcesiran, as part of the SHINE clinical development program for the treatment of AATLD. The ESTRELLA Phase 2 trial is a randomized, multidose, double-blind, placebo-controlled study evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of belcesiran in participants with AATLD.

• Completed Nedosiran PHYOX4 Clinical Trial Dosing for Treatment of Primary Hyperoxaluria Type 3. In June 2021, Dicerna announced completion of patient dosing in its PHYOX4 trial, a randomized, placebo-controlled, double-blind, multicenter study evaluating safety and tolerability of nedosiran for the treatment of PH3. PHYOX4 is a part of the PHYOX clinical development program evaluating nedosiran in patients with all three known subtypes of PH. The Company expects to report top-line results from this study in October 2021.

Collaboration Updates

• Reported FDA Acceptance of IND for LY3819496 Filed by Eli Lilly and Company (“Lilly”). In May 2021, Dicerna announced FDA acceptance of Lilly’s IND for LY3819469, the second clinical-stage investigational GalXC RNAi candidate to emerge from Dicerna’s collaboration with Lilly. The IND milestone triggered a $10.0 million payment to Dicerna, and in June 2021, Lilly initiated dosing in a Phase 1 clinical trial of LY3819469, targeting the LPA gene, as a potential treatment of cardiometabolic diseases.

• Announced Boehringer Ingelheim’s Acceptance of DCR-LIV2 for Development Under RNAi Research Collaboration and License Agreement. In May 2021, Dicerna announced Boehringer Ingelheim’s (BI) acceptance of DCR-LIV2, an investigational GalXC RNAi candidate for advancement under the existing agreement between the companies for the discovery and development of novel therapies for the treatment of chronic liver diseases. DCR-LIV2 will be evaluated for the treatment of nonalcoholic steatohepatitis (NASH), a chronic liver disease for which there are no approved therapeutic interventions. This candidate acceptance triggered a single-digit multimillion-dollar preclinical milestone payment to Dicerna in the second quarter of 2021.

Anticipated Upcoming 2021 Milestones

• Nedosiran:
  • Top-line data from PHYOX4 trial in patients with PH3 in October 2021
  • Initiate PHYOX8 trial, an open-label study in patients aged 0-5 years with PH1 or PH2, in the third quarter of 2021
  • NDA submission in the fourth quarter of 2021

• Belcesiran: Present Phase 1 data at a medical congress, subject to abstract acceptance

• DCR-AUD: Initiate Phase 1 study in healthy volunteers in the third quarter of 2021

Financial Results for the Second Quarter Ended June 30, 2021

• Cash Position – As of June 30, 2021, Dicerna had $709.6 million in cash, cash equivalents and held-to-maturity investments, compared to $568.8 million as of Dec. 31, 2020.

• Revenue – Dicerna recognized $41.3 million of revenue for the second quarter 2021, compared to $40.4 million for the same period in 2020. Revenue was relatively flat for the second quarter 2021, compared to the same period in 2020, as increases in Lilly, Novo, and BI revenues were largely offset by decreases in Roche and Alexion revenues.

• Research and Development (R&D) Expenses – R&D expenses were $56.1 million for the second quarter 2021, compared to $53.4 million for the same period in 2020. The increase was primarily due to increases in facilities, depreciation, and other expenses and employee-related expenses as a result of an increase in R&D headcount necessary to support the Company’s expanding pipeline and collaboration agreements. These increases were largely offset by a decrease in direct R&D expenses, primarily due to decreases in drug substance expense.

• General and Administrative (G&A) Expenses – G&A expenses were $25.5 million for the second quarter 2021, compared to $20.6 million for the same period in 2020. The increase was primarily due to an increase in professional consulting fees.

• Net Loss – Net loss was $40.8 million, or $0.53 per share, for the second quarter ended June 30, 2021, compared to a net loss of $31.8 million, or $0.43 per share, for the same period in 2020.

Guidance

Dicerna believes that its cash, cash equivalents, held-to-maturity investments, and anticipated milestone and other payments from existing collaborations will be sufficient to fund the execution of its current clinical and operating plan into 2025, which includes supporting all R&D activities for current internal and collaboration pipeline programs. This estimate assumes no funding from new collaboration agreements or from external financing events and no significant unanticipated changes in costs and expenses.

Dicerna expects its research and development expenses to continue to increase for the foreseeable future, largely due to clinical manufacturing activities, continued clinical activities associated with its core product candidates and continued activities under its existing collaboration agreements. The Company continues to forecast receiving $83.0 million in cash from its current collaboration agreements during full-year 2021, of which $74.5 million has been received in the first six months of 2021.
