ROCKVILLE, Md., May 7, 2020 /PRNewswire/ -- 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 March 31, 2020, and recent operational highlights.

"Our overall focus at REGENXBIO during the COVID-19 pandemic is on the health and safety of our people and our communities, as well as the important work that we need to continue in order to help patients," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. "We recently reported additional positive data from our RGX-314 Phase I/IIa wet AMD trial which demonstrated long-term, sustained clinical outcomes in patients after a one-time administration of RGX-314 gene therapy. We look forward to initiating a pivotal program for the subretinal delivery of RGX-314 for wet AMD as well as additional studies using the suprachoroidal delivery approach in both wet AMD and diabetic retinopathy in 2020. We also anticipate providing updates throughout 2020 from our other programs, including the Phase I/II trials of RGX-121 for the treatment of MPS II and RGX-501 for the treatment of HoFH."

Mr. Mills added: "We continue to track the positive progress of Novartis' Zolgensma which uses the NAV AAV9 vector for the treatment of pediatric patients with spinal muscular atrophy (SMA). We are encouraged by the recent regulatory updates from Japan and Europe, and we look forward to continued sales growth for Zolgensma. After more than a decade of steadfast effort and focus, we remain dedicated and committed to improving lives through the curative potential of gene therapy."

Recent Operational Highlights

Gene Therapy Using NAV Vectors for AAV-Mediated Antibody Delivery

RGX-314 for the Treatment of Wet AMD

In April 2020, REGENXBIO reported positive additional data from the RGX-314 Phase I/IIa trial using subretinal delivery. As of April 6, 2020:

RGX-314 continued to be well-tolerated at all dose levels.
Long-term, durable treatment effect was demonstrated in Cohort 3:

Mean improvement in vision (+14 letters) and stable retinal thickness (+2 µm) observed at two years.
50% of patients (3/6) remained anti-VEGF injection-free over two years.
67% of patients (4/6) were anti-VEGF injection-free from nine months to two years.
Stable intraocular RGX-314 protein expression observed over two years.

73% of patients (8/11) in Cohort 5 were anti-VEGF injection-free over nine months.
Intraocular RGX-314 protein levels at six months demonstrated dose-dependent expression across cohorts.

REGENXBIO expects to initiate a pivotal program for the subretinal delivery of RGX-314 for the treatment of wet AMD in the second half of 2020.

REGENXBIO plans to finalize the design of the trial based on the one-year assessment of patients in Cohorts 4 and 5 in the Phase I/IIa trial and expects to begin dosing patients in the trial in the second half of 2020.

REGENXBIO plans to initiate the Phase II trial for the suprachoroidal delivery of RGX-314 using the SCS Microinjector™ for the treatment of wet AMD in the first half of 2020.

Interim data is expected from the first cohort by the end of 2020.

RGX-314 for the Treatment of Diabetic Retinopathy (DR)

REGENXBIO plans to evaluate RGX-314 using the SCS Microinjector for the treatment of DR, and expects to submit an investigational new drug (IND) application for a Phase II trial in mid-2020.

REGENXBIO plans to initiate the trial in the second half of 2020 and interim data is expected in 2021.

Research Program for the Treatment of Hereditary Angioedema (HAE)

Lead product candidate selection is expected in the first half of 2020 and REGENXBIO expects to provide a program update in the second half of 2020.

Research Program for the Treatment of Neurodegenerative Diseases

REGENXBIO previously announced the expansion of the exclusive collaboration with Neurimmune AG to design and develop vectorized antibody therapies targeting both alpha synuclein and tau. REGENXBIO expects to provide a program update in the second half of 2020.

Gene Therapy Using NAV Vectors for Rare Genetic Diseases

RGX-121 for the Treatment of Mucopolysaccharidosis Type II (MPS II)

Initial data from Cohort 1 of the Phase I/II trial were presented at the WORLDSymposium conference in February 2020 and REGENXBIO expects to provide additional data from this cohort in mid-2020.
REGENXBIO expects to complete enrollment of patients in Cohort 2 in the first half of 2020, with interim data anticipated in the second half of 2020.

RGX-111 for the Treatment of Mucopolysaccharidosis Type I (MPS I)

Recruitment, screening and additional site activations are ongoing in the Phase I/II trial.
REGENXBIO expects to provide a program update in the second half of 2020.

RGX-181 for the Treatment of Late-infantile Neuronal Ceroid Lipofuscinosis Type 2 (CLN2) Disease

REGENXBIO is conducting ongoing preclinical development of RGX-181, including assessment of unmet clinical needs such as neurologic and ophthalmologic manifestations of the disease. REGENXBIO expects to provide a program update in mid-2020 and submit an IND for a first-in-human trial in the second half of 2020.

RGX-501 for the Treatment of Homozygous Familial Hypercholesterolemia (HoFH)

As previously announced, REGENXBIO completed dosing of an expanded Cohort 2 in the Phase I/II trial and plans to assess low-density lipoprotein (LDL-C) levels after all patients have completed steroid prophylaxis treatment. REGENXBIO expects to provide a program update in the first half of 2020.

Research Program for the Treatment of Neuromuscular Disorders

REGENXBIO expects to announce plans for clinical development of a potential treatment for a neuromuscular disorder using NAV AAV8 in the second half of 2020.

Current Good Manufacturing Practice (cGMP) Manufacturing Facility

Construction of a new corporate, research and manufacturing headquarters in Rockville, Maryland continues, with plans to begin utilizing the new headquarters in late 2020.
The new cGMP production facility is expected to allow for production of NAV vectors at scales up to 2,000 liters using REGENXBIO's platform suspension cell culture process, which will complement REGENXBIO's current external manufacturing network and capabilities. The cGMP facility is expected to be operational starting in 2021.

Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $356.6 million as of March 31, 2020, compared to $400.0 million as of December 31, 2019. The decrease was primarily attributable to net cash used in operating activities of $35.6 million and cash used to purchase property and equipment of $4.6 million.

Revenues: Revenues were $17.6 million for the three months ended March 31, 2020, compared to $0.9 million for the three months ended March 31, 2019. The increase was primarily attributable to $10.0 million of royalty revenue recognized on net sales of Zolgensma in the first quarter of 2020, as well as $7.2 million of license revenue recognized from a new license granted to Ultragenyx Pharmaceutical Inc. during the period. Commercial sales of Zolgensma commenced in the second quarter of 2019, and REGENXBIO is eligible to receive a milestone payment of $80.0 million from AveXis, Inc. upon the achievement of $1.0 billion in cumulative net sales of Zolgensma.

Research and Development Expenses: Research and development expenses were $37.0 million for the three months ended March 31, 2020, compared to $25.2 million for the three months ended March 31, 2019. The increase was primarily attributable to personnel-related costs as a result of increased headcount, laboratory and facilities costs, expenses associated with conducting clinical trials for our lead product candidates and externally sourced services for preclinical, regulatory and manufacturing-related activities.

General and Administrative Expenses: General and administrative expenses were $14.8 million for the three months ended March 31, 2020, compared to $11.6 million for the three months ended March 31, 2019. The increase was primarily attributable to personnel-related costs as a result of increased headcount and professional fees for advisory and other services.

Net Loss: Net loss was $40.0 million, or $1.08 basic and diluted net loss per share, for the three months March 31, 2020, compared to net loss of $32.2 million, or $0.89 basic and diluted net loss per share, for the three months ended March 31, 2019.

Financial Guidance

Based on its current operating plan, REGENXBIO expects its balance in cash, cash equivalents and marketable securities of $356.6 million to fund the completion of its internal manufacturing capabilities and clinical advancement of its product candidates into 2022.
