(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 fourth quarter and year ended December 31, 2023, and provided a corporate update.
“2023 was a productive year for Regulus, and the growing momentum in our Phase 1b MAD study of RGLS8429 is further emphasized by our announcement of key milestones and data readouts, including the recent positive topline data from the second cohort of patients. In the topline data, we saw evidence of a mechanistic dose response at a 2 mg/kg dose level based on urinary polycystin levels and in particular their potential correlation with improvements in kidney volume and function” said Jay Hagan, CEO of Regulus. “Thanks to the strong data we’ve seen to date and the ongoing support of our shareholders, we completed an oversubscribed $100 million private placement this month, which is expected to extend our cash runway into the first half of 2026. We look forward to a busy 2024, including sharing top-line data from our third cohort, expected in mid-2024, and the initiation of our fourth and final cohort of the MAD study next quarter.” Program Updates RGLS8429 for ADPKD: In March 2024, the Company shared positive topline data from the second cohort of patients in the Phase 1b MAD study of RGLS8429 for the treatment of ADPKD. In the second cohort, 14 patients were randomized 3:1 to receive either 2 mg/kg of RGLS8429 or placebo every other week for three months. RGLS8429 was well tolerated with no safety findings of concern. Greater biological activity of RGLS8429 was observed at 2 mg/kg based on urinary polycystin levels compared to 1mg/kg and placebo, which was most evident after 3 months of dosing. Exploratory results of imaging-based biomarkers were encouraging with 3 patients with the highest increases in PC1 and PC2 having reductions in height-adjusted total kidney volume (htTKV) >4%, with corresponding reductions in total kidney cyst volume (TKCV). These data suggest that targeting miR-17 may have a potential impact on htTKV and TKCV in patients with ADPKD, which the Company will further explore at higher doses in cohorts 3 and 4. The Phase 1b MAD study is a double-blind, placebo-controlled trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics (PK/PD) of RGLS8429 in adult patients with ADPKD. The study is evaluating RGLS8429 treatment across three different weight-based dose levels, including measuring changes in urinary polycystins 1 and 2 (PC1 and PC2), htTKV, cyst architecture, and overall kidney function. In November 2023, Regulus announced it had dosed the first patient in the third cohort of the Phase 1b MAD study. This cohort is receiving 3 mg/kg of RGLS8429 or placebo every other week for three months. In January, the Company announced that it had completed enrollment in cohort 3 with top-line data expected in mid-2024. In late 2023, Regulus amended the protocol for the Phase 1b MAD study to include a fourth cohort that will receive an open label fixed dose of 300 mg of RGLS8429 that will provide higher exposure in a larger number of patients based on anticipated body weight in order to compare biomarker and safety data to the weight-based dosing, with initiation of screening planned for Q2 2024. Based on the results from the second cohort, the Company plans to amend the protocol to increase the sample size to up to 30 patients in cohort 4. In December 2023, the Company held a successful Type D meeting with the U.S. Food and Drug Administration (FDA) to discuss the accelerated approval pathway. The meeting was constructive and confirmed the potential for an accelerated approval pathway based on a single pivotal Phase 2 study of RGLS8429 for the treatment of ADPKD. The FDA has adopted an accelerated approval pathway for ADPKD based on a single pivotal trial demonstrating statistically significant reduction in TKV growth compared to placebo, with completion of a post approval Phase 3 trial as a post-marketing requirement, demonstrating a statistically significant improvement in estimated glomerular filtration rate (eGFR) compared to placebo. Corporate Highlights Closed Oversubscribed $100 Million Private Placement: On March 12, 2024, the Company announced that it entered into a definitive securities purchase agreement in connection with a private placement to certain institutional and other accredited investors. The financing included participation from new and existing institutional investors, including Adage Capital Partners L.P., Deep Track Capital, the Federated Hermes Kaufmann Funds, New Enterprise Associates (NEA), Octagon Capital, RA Capital Management, and Vivo Capital. Financial Results Cash and Cash Equivalents: As of December 31, 2023, Regulus had $23.8 million in cash and cash equivalents. Combined with the $100 million private placement equity financing in March, the Company expects its cash runway to extend into H1 2026. Research and Development (R&D) Expenses: Research and development expenses were $5.8 million and $21.2 million for the fourth quarter and year ended December 31, 2023, respectively, compared to $4.7 million and $18.4 million for the same periods in 2022, respectively. General and Administrative (G&A) Expenses: General and administrative expenses were $2.5 million and $10.0 million for the fourth quarter and year ended December 31, 2023, respectively, compared to $2.2 million and $9.8 million for the same periods in 2022, respectively. Net Loss: Net loss was $8.1 million, or $0.40 per share (basic and diluted), and $30.0 million, or $1.58 per share (basic and diluted), for the fourth quarter and year ended December 31, 2023, compared to $6.8 million, or $0.40 per share (basic and diluted), and $28.3 million, or $1.86 per share (basic and diluted), for the same periods in 2022. About ADPKD Autosomal Dominant Polycystic Kidney Disease (ADPKD), caused by 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. Approximately 160,000 individuals are diagnosed with the disease in the United States alone, with an estimated global prevalence of 4 to 7 million. About RGLS8429 RGLS8429 is a novel, next generation oligonucleotide for the treatment of ADPKD designed to inhibit miR-17 and to preferentially target the kidney. Administration of RGLS8429 has shown robust data in preclinical models, where clear improvements in kidney function, size, and other measures of disease severity have been demonstrated along with a superior pharmacologic profile in preclinical studies compared to Regulus’ first-generation compound, RGLS4326. Regulus announced completion of the Phase 1 SAD study in September 2022. The Phase 1 SAD study demonstrated that RGLS8429 has a favorable safety and PK profile. RGLS8429 was well-tolerated with no serious adverse events reported and plasma exposure was approximately linear across the four doses tested and is similar to the PK data from the first-generation compound. In the Phase 1b MAD study Regulus announced both top line data from the first cohort of patients in September 2023 and from the second cohort of patients in March 2024. After review of all available safety data from the second cohort, Regulus has advanced to the third cohort where dosing has begun, and patients are receiving 3 mg/kg of RGLS8429 or placebo every other week for three months. Regulus announced completion of enrollment in the third cohort in January 2024 with top-line data anticipated in mid-2024. About Regulus Regulus Therapeutics Inc.
