"We have completed the second cohort and have initiated the dosing for the third and final cohort in the Phase 1 multiple ascending dose ("MAD") clinical study for RGLS4326" said Jay Hagan, CEO of Regulus. "Additionally, preparations for the Phase 1b study in patients with autosomal dominant polycystic kidney disease ("ADPKD") are well underway with plans to initiate in the second half of 2020."
Program Highlights
Initiated Dosing of the Third and Final Cohort in RGLS4326 Phase 1 for ADPKD: In April 2020, the Company initiated dosing of the third and final cohort of the MAD clinical study of RGLS4326, a novel oligonucleotide designed to inhibit miR-17 for the treatment of ADPKD. The Company expects to complete this study in mid-2020 with topline results available thereafter. The Company is planning to initiate a Phase 1b short-term dosing study in patients with ADPKD in the second half of 2020 to evaluate RGLS4326 for safety, pharmacokinetics, and biomarkers of pharmacodynamic activity.
Financial Results
Cash Position: As of March 31, 2020, Regulus had $28.1 million in cash and cash equivalents.
Research and Development (R&D) Expenses: R&D expenses were $3.1 million for the three months ended March 31, 2020, compared to $6.0 million for the same period in 2019. The aggregate decrease was driven by a $1.5 million reduction in personnel and internal expenses and a $1.0 million reduction in external development expenses, both of which were primarily attributable to a reduction in costs associated with the partial clinical hold of the RGLS4326 MAD study. In December 2019, the U.S. Food and Drug Administration ("FDA") lifted the partial clinical hold on the MAD study and it was recommenced in February 2020.
General and Administrative (G&A) Expenses: G&A expenses were $2.4 million for the three months ended March 31, 2020 compared to $3.5 million for the same period in 2019. These amounts reflect personnel-related and ongoing general business operating costs. The decrease is primarily attributable to continued cost reduction efforts subsequent to our corporate restructuring in the third quarter of 2018.
Revenue: Revenue was less than $0.1 million for the three months ended March 31, 2020. Revenue was $6.8 million for the three months ended March 31, 2019, attributable to revenue recognition of the upfront payments received under the 2018 Sanofi Amendment related to the transfer of the RG-012 program to Sanofi.
Net Loss: Net loss was $5.9 million, or $0.25 per share (basic and diluted), for the three months ended March 31, 2020, compared to $3.3 million, or $0.31 per share (basic and diluted), for the same period in 2019.
About 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.
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. The RGLS4326 IND is currently on a Partial Clinical Hold for treatment of extended duration by the U.S. Food and Drug Administration until the second set of requirements outlined by FDA have been satisfactorily addressed. Information from the Phase 1 clinical studies, together with information from additional nonclinical studies, will be used to address the second set of requirements to support studies of extended duration.
