REGENXBIO Inc. (Nasdaq: RGNX), a leading clinical-stage biotechnology company seeking to improve lives through the curative potential of gene therapy based on its proprietary NAV® Technology Platform, today announced financial results for the quarter ended September 30, 2019, and recent operational highlights.
"We continue to make significant advances in our pipeline and NAV Technology Platform, expanding the pipeline with programs to deliver therapeutic antibodies, beginning an exciting collaboration with Neurimmune, and initiating construction of a new manufacturing facility," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. "Our focus on patients drives us to build upon the clinical progress of gene therapy options for both large indications and rare diseases, and we are excited to lead the field in innovative approaches. We are also very encouraged by the early adoption of the first approved NAV Technology-based therapy, Novartis' Zolgensma®, for the treatment of SMA."
"We anticipate a short delay in the initiation of our Phase IIb trial for RGX-314 in wet AMD and our investigative new drug, or IND, application filing for diabetic retinopathy, following notification from the FDA regarding certain third-party commercially-available surgical devices that were used to deliver RGX-314 in our Phase I/IIa trial," added Mr. Mills. "The notification is not related to the RGX-314 gene therapy itself, and we have not received reports of any device-related concerns or complications in the subjects already dosed in the Phase I/IIa trial. Assessments and monitoring of all enrolled subjects in the trial continue to be performed as usual. We are working with the FDA to address this matter, and as a result, we now plan to initiate our Phase IIb trial for RGX-314 in wet AMD and file our IND for diabetic retinopathy in Q1 2020,"
"We are encouraged by the data from the Phase I/IIa clinical trial of RGX-314 in patients with wet AMD," said Dr. Stephen Pakola, Senior Vice President and Chief Medical Officer of REGENXBIO. "These data demonstrate significant long-term reduction of anti-VEGF treatment burden while maintaining or improving vision and retinal thickness after a single administration of our gene therapy. We look forward to initiating our Phase IIb trial of RGX-314 in wet AMD, and preparing to file an IND to evaluate RGX-314 in diabetic retinopathy, while continuing our collaboration with Clearside to evaluate the in-office suprachoroidal administration of RGX-314. We have also achieved important clinical development milestones in our other gene therapy programs, including completing dosing of Cohort 2 in our RGX-501 trial for HoFH and Cohort 1 in our RGX-121 trial for MPS II. Our internal pipeline of novel gene therapies positions us to develop meaningful potential treatments for a broad spectrum of patients with significant unmet needs."
Product Candidate Updates
Gene Therapy using NAV Vectors for AAV-Mediated Antibody Delivery:
- RGX-314 for the Treatment of Wet Age-related Macular Degeneration (wet AMD) and Diabetic Retinopathy (DR)
- REGENXBIO has been informed by the U.S. Food and Drug Administration (FDA) that they are assessing aspects of the surgical delivery system, specifically the use of certain third-party commercially-available devices that are used to deliver RGX-314 in our Phase I/IIa trial for the treatment of wet AMD. As previously announced, this trial has completed dosing of all 42 patients with RGX-314. While discussions with the FDA are ongoing, however, the IND for the trial has been placed on a partial clinical hold, which is not related to the gene therapy product candidate itself. The Company is not aware of any delivery system concerns or complications from the Phase I/IIa trial, nor is it aware of any concerns or actions related to these third-party device suppliers or other companies using similar devices in AAV gene therapy surgical delivery systems. Regular assessments and safety monitoring of all subjects enrolled in the Phase I/IIa trial continue to be performed as normal.
- The Company is conducting a review of the third-party device components and believes that there are readily available and suitable alternatives for these third-party devices, if needed. REGENXBIO will continue to work closely with the FDA regarding the potential replacement, testing or modification of third-party devices. As a result of these activities, REGENXBIO now expects to initiate the RGX-314 Phase IIb trial for wet AMD and file an IND for the Phase II trial in DR in the first quarter of 2020.
- In October 2019, REGENXBIO presented interim results from all five dose cohorts of the RGX-314 Phase I/IIa dose escalation clinical trial in subjects with wet AMD at the American Academy of Ophthalmology Annual Meeting (AAO). As of October 9, 2019, RGX-314 continued to be well-tolerated across all cohorts, with no drug-related serious adverse events (SAEs) reported. Up to six months after administration of RGX-314, subjects in Cohort 5 demonstrated a reduction of over 80% from the mean annualized injection rate during the 12 months prior to administration of RGX-314, and 75% of subjects had not received anti-VEGF injections, with mean improvement in vision and retinal thickness. Durable effects on vision and retinal thickness had been demonstrated over 1.5 years in Cohort 3, and 50% of subjects remained free of anti-VEGF injections more than 1.5 years after RGX-314 administration.
- REGENXBIO continues to evaluate in-office delivery of RGX-314 to the suprachoroidal space. Clinical plans for this route of administration are expected to be announced in 2020.
- Hereditary Angioedema (HAE)
- REGENXBIO expects to provide an update in early 2020 on the preclinical studies of a new gene therapy product candidate for the treatment of HAE, as well as plans for clinical development.
- Neurodegenerative Diseases
- REGENXBIO initiated design and development of vectorized antibody therapies in collaboration with Neurimmune AG, using Neurimmune's Reverse Translational Medicine™ platform along with the Company's NAV Technology Platform. Initially, the companies are focusing on diseases associated with the accumulation and deposition of the microtubule-associated protein tau (tauopathies).
Gene Therapy using NAV Vectors for Rare Genetic Diseases:
- RGX-501 for the Treatment of Homozygous Familial Hypercholesterolemia (HoFH)
- REGENXBIO completed dosing of subjects in Cohort 2 in the Phase I/II clinical trial evaluating RGX-501 for the treatment of HoFH with corticosteroid prophylaxis and expects to report interim data at the end of 2019.
- The primary endpoint of this trial is safety and tolerability, and secondary endpoints include changes in low-density lipoprotein (LDL-C) and other lipid outcome measures.
- RGX-121 for the Treatment of Mucopolysaccharidosis Type II (MPS II)
- REGENXBIO completed dosing of subjects in Cohort 1 in the Phase I/II clinical trial evaluating RGX-121 for the treatment of MPS II. The Company expects to report an interim data update from the Phase I/II clinical trial at the end of 2019.
- The primary endpoint of this trial includes safety and tolerability, and secondary endpoints include change in biomarkers as measured in cerebrospinal fluid, serum and urine, and change in neurodevelopmental parameters.
- RGX-111 for the Treatment of Mucopolysaccharidosis Type I (MPS I)
- RGX-111 was recently administered to a subject with MPS I through an investigator-initiated study at CHOC Children's Hospital, following review and agreement by the FDA. As of November 4, 2019, RGX-111 has been well-tolerated.
- Recruitment, screening and additional site activations are ongoing in the Phase I clinical trial evaluating RGX-111 for the treatment of MPS I.
- RGX-181 for the Treatment of Late-infantile Neuronal Ceroid Lipofuscinosis Type 2 (CLN2) "Batten" Disease
- REGENXBIO intends to submit an IND (or foreign equivalent) for the first-in-human clinical trial evaluating RGX-181 in the second half of 2020, following additional preclinical development and analyses to support clinical development.
- Preclinical data presented at the European Society of Gene & Cell Therapy (ESGCT) 27th Annual Congress highlighted outcomes from a murine mouse model for CLN2 Batten disease.
Other Recent Operational Highlights
- In October 2019, REGENXBIO exercised the full option with Clearside Biomedical, Inc. for exclusive worldwide rights to Clearside's proprietary, in-office SCS Microinjector™ for the delivery of AAV vectors to the suprachoroidal space to treat a number of indications. REGENXBIO continues to evaluate RGX-314 using Clearside's SCS Microinjector for in-office, non-surgical delivery into the suprachoroidal space to treat wet AMD, DR and other conditions for which anti-VEGF treatment is currently the standard of care, while continuing to advance its RGX-314 subretinal delivery program currently in development.
- Construction of REGENXBIO's current good manufacturing practice (cGMP) production facility continues as planned. The new cGMP production facility is designed to allow for production of NAV Technology-based vectors at scales up to 2,000 liters using REGENXBIO's platform suspension cell culture process. The facility is expected to be operational in 2021.
NAV Technology Licensee Program Highlights
As of October 31, 2019, REGENXBIO's NAV Technology Platform was being applied in one marketed product, Novartis AG's Zolgensma, and more than 20 partnered product candidates in development by NAV Technology Licensees. Fifteen of these partnered product candidates are in active clinical development. REGENXBIO's NAV Technology Licensees are advancing product candidates in a broad range of therapeutic areas and disease indications. Recent updates from NAV Technology Licensees include:

Cash, cash equivalents and marketable securities were $417.1 million as of September 30, 2019, compared to $470.6 million as of December 31, 2018. The decrease in cash, cash equivalents and marketable securities during the nine months ended September 30, 2019, was primarily attributable to $82.2 million of net cash used in operating activities during the period, partially offset by an unrealized gain of $29.4 million related to our marketable equity securities of Prevail Therapeutics Inc.
Revenues were $14.7 million for the three months ended September 30, 2019, compared to $5.3 million for the three months ended September 30, 2018. The increase was primarily attributable $9.2 million of royalty revenue recognized during the third quarter of 2019 related to net sales of Zolgensma. Commercial sales of Zolgensma commenced in the second quarter of 2019, and we are also eligible to receive a milestone payment of $80.0 million from AveXis, Inc. upon the achievement of $1 billion in cumulative net sales of Zolgensma.
Research and development expenses were $35.7 million for the three months ended September 30, 2019, compared to $18.5 million for the three months ended September 30, 2018. The increase was primarily attributable to personnel costs as a result of increased headcount, laboratory and facilities costs and external expenses associated with conducting clinical trials and manufacturing-related services.
General and administrative expenses were $12.4 million for the three months ended September 30, 2019, compared to $9.0 million for the three months ended September 30, 2018. The increase was primarily attributable to personnel costs as a result of increased headcount.
Net loss was $34.6 million, or $0.94 basic and diluted net loss per share, for the three months ended September 30, 2019, compared to net loss of $19.2 million, or $0.56 basic and diluted net loss per share, for the three months ended September 30, 2018.
Based on its current operating plan, REGENXBIO now expects its balance in cash, cash equivalents and marketable securities to be at least $365 million as of December 31, 2019.
