Regulus Therapeutics Reports First Quarter 2019 Financial Results and Recent Updates

LA JOLLA, Calif., May 9, 2019 /PRNewswire/ -- Regulus Therapeutics Inc. (Nasdaq: RGLS), a biopharmaceutical company focused on the discovery and development of innovative medicines targeting microRNAs (the "Company" or "Regulus"), today reported financial results for the first quarter ended March 31, 2019 and provided a summary of recent events.

"I am proud of the significant progress we have made thus far in 2019 to reposition Regulus with a strengthened balance sheet, restructured term loan and reduced operating cash burn rate. Importantly, the team has maintained its focus in its engagement with FDA, and we look forward to resuming our ADPKD clinical program pending FDA alignment. We believe the total potential proceeds from the recent financing, highlighted by a strong investor syndicate, provides sufficient capital to fund planned activities into the second half of 2021," said Jay Hagan, CEO of Regulus. "We look forward to providing future updates on our ADPKD program, as well as further advancements from our promising preclinical pipeline."

First Quarter 2019 Corporate Highlights and Recent Updates

    --  Private Financing: In May 2019, the Company closed the first tranche of
        its $41.8 million private placement of equity (the "Private Placement").
        Regulus received net proceeds of approximately $15.7 million from the
        first tranche, after deducting placement agent fees and other offering
        expenses. Subject to the Company's public announcement on or before
        December 31, 2019 of its plan to recommence the Phase 1 multiple
        ascending dose clinical trial for RGLS4326 based upon correspondence
        from FDA, the investors who purchased securities in the first tranche of
        the Private Placement have agreed to purchase shares of non-voting
        convertible preferred stock and accompanying warrants to purchase shares
        of common stock in a second closing (the "Milestone Closing"). If the
        Milestone Closing occurs, the gross proceeds to the Company from that
        closing will be approximately $25.1 million. The Company expects to use
        the proceeds from the Private Placement primarily to advance RGLS4326
        for the treatment of ADPKD, to advance select programs from its pipeline
        of microRNA therapies and for general corporate purposes.
    --  Term Loan Amendments: In January 2019, March 2019, and April 2019 the
        Company amended its Term Loan with Oxford Finance to provide for
        additional periods of interest only for the months of February 2019,
        March 2019, and April 2019, respectively. The maturity date of the Term
        Loan remained unchanged. In May 2019, and concurrently with the Private
        Placement, the Company amended its Term Loan with Oxford Finance to
        provide a new twelve-month period of interest-only payments, commencing
        May 2019, and a two-year extension of its maturity date from June 2020
        to May 2022. Upon the closing of the second tranche of the Company's
        Private Placement, the Company will receive an additional twelve-month
        period of interest-only payments, commencing May 2020.
    --  RG-012 Transition to Sanofi: In November 2018, the Company and Sanofi
        agreed to transition further development activities of the miR-21
        programs, including the Company's RG-012 program, to Sanofi who will be
        responsible for all costs incurred in the development of these miR-21
        programs (the "2018 Sanofi Amendment"). As of March 31, 2019, the
        transition activities, including the transfer of the investigational new
        drug application (""IND"), were substantially completed. The Company
        received $2.5 million and $1.8 million in upfront and material
        transfer-related payments in November 2018 and March 2019, respectively.
        In April 2019, the Company received an additional $2.5 million upfront
        payment. These payments, totaling $6.8 million, were recognized as
        revenue in the first quarter ended March 31, 2019. Regulus is also
        eligible to receive up to $40 million in clinical milestone payments.
    --  Lease Agreement: In February 2019, the Company entered into an amendment
        of its lease (the "Lease Amendment") of 59,248 square feet located at
        10614 Science Center Drive, San Diego, California 92121. Under the terms
        of the Lease Amendment, the expiration of the lease was accelerated from
        April 30, 2024 to March 31, 2019 and the lease terminated on April 1,
        2019. Concurrently with the Lease Amendment, the Company entered into a
        new lease agreement (the "Lease") for 24,562 square feet at 10628
        Science Center Drive, Suite 100, San Diego, California, 92121, which it
        expects to use as its new principal offices and laboratory for research
        and development. This relocation reduced the Company's facility size by
        approximately 60% and reduced its future contractual lease obligations
        by approximately 70%.

Program Updates

    --  RGLS4326 for ADPKD: In January 2019, the Company announced data from a
        planned interim analysis of a new mouse chronic toxicity study after 13
        weeks of dosing in which no adverse or other significant findings across
        the range of doses tested were shown. In January 2019, the Company
        submitted a comprehensive data package for RGLS4326 to FDA that included
        the results from the planned 13-week interim analysis of the repeat
        mouse chronic toxicity study, as well as results from additional
        investigations, analytical testing, additional data from the previously
        terminated mouse chronic toxicity study, data from the completed Phase I
        SAD study and data from the first cohort of the Phase I MAD study, to
        support its plan to resume the Phase I MAD study. The Company's
        engagement with FDA is ongoing.
    --  RGLS5579 for Glioblastoma Multiforme (GBM): In January 2019, the Company
        announced RGLS5579 as a clinical candidate for the treatment of GBM.
        RGLS5579, which targets microRNA-10b, demonstrated statistically
        significant improvements in survival as both a monotherapy as well as in
        combination with temozolomide ("TMZ") in an orthotopic GBM animal model.
        In combination with TMZ, the addition of a single dose of RGLS5579,
        delivered intracranially, led to a more than two-fold improvement in
        survival compared to TMZ alone. The Company plans to seek a partner to
        further advance RGLS5579 development.
    --  Anti-miR-132 for Nonalcoholic Steatohepatitis (NASH): In April 2019,
        Regulus presented a late breaker poster at the EASL International Liver
        Congress(TM) describing the development of its lead anti-miR-132 for the
        treatment of NASH. Across multiple animal models of NASH, the lead
        candidate demonstrated improvement in key endpoints, including NAFLD
        Activity Score (NAS), liver transaminases, hyperglycemia, and
        disease-related gene expression. In the diet-induced NASH mouse model
        (Amylin model) after two to four weekly doses, early onset of
        improvement across multiple disease parameters including liver
        triglycerides and blood levels of transaminases was observed. After nine
        weeks of treatment, there was evidence of sustained benefit with
        significant improvement of liver fibrosis and hyperglycemia compared to
        control-treated animals. The Company believes that targeting
        dysregulated microRNA in a complex disease like NASH may offer a unique
        mechanism of action from other programs in development. The Company
        plans to seek a partner to further advance the development of this
        program.

First Quarter 2019 Financial Results

Revenue: Revenue was $6.8 million for the three months ended March 31, 2019, compared to less than $0.1 million for the three months ended March 31, 2018. The increase was associated with revenue recognition of the upfront payments received under the 2018 Sanofi Amendment related to the transfer of RG-012 during the three months ended March 31, 2019.

Cash Position: As of March 31, 2019, Regulus had $10.3 million in cash and cash equivalents.

Research and Development (R&D) Expenses: R&D expenses were $6.0 million for the three months ended March 31, 2019, compared to $11.8 million for the same period in 2018. The aggregate decrease was driven by a $3.8 million decrease in external development expenses during the three months ended March 31, 2019, primarily attributable to the pausing of the RGLS4326 program in the third quarter of 2018 and commencement of the transfer of the RG-012 program to Sanofi under the 2018 Sanofi Amendment in the fourth quarter of 2018. In addition, personnel and internal expenses decreased by approximately $1.9 million, primarily as a result of a reduction in headcount and related costs subsequent to our corporate restructuring in the third quarter of 2018.

General and Administrative (G&A) Expenses: G&A expenses were $3.5 million for the three months ended March 31, 2019 compared to $3.8 million for the same period in 2018. These amounts reflect personnel-related and ongoing general business operating costs.

Net Loss: Net loss was $3.3 million, or $0.31 per share (basic and diluted), for the three months ended March 31, 2019, compared to $16.0 million, or $1.85 per share (basic and diluted), for the same period in 2018. Historical and current period net loss per share values have been retroactively adjusted to reflect our October 2018 reverse stock split.

About Autosomal Dominant Polycystic Kidney Disease (ADPKD)

ADPKD, caused by the mutations in the PKD1 or PKD2 genes, is among the most common human monogenic disorders and a leading cause of end-stage renal disease. The disease is characterized by the development of multiple fluid filled cysts primarily in the kidneys, and to a lesser extent in the liver and other organs. Excessive kidney cyst cell proliferation, a central pathological feature, ultimately leads to end-stage renal disease in approximately 50% of ADPKD patients by age 60. It is estimated that approximately 1 in 1,000 people bear a mutation in either PKD1 or PKD2 genes worldwide.

About RGLS4326

RGLS4326 is a novel oligonucleotide designed to inhibit miR-17 and designed to preferentially target the kidney. Preclinical studies with RGLS4326 have demonstrated direct regulation of PKD1 and PKD2 in human ADPKD cyst cells, a reduction in kidney cyst formation, improved kidney weight/body weight ratio, decreased cyst cell proliferation, and preserved kidney function in mouse models of ADPKD.
