ROCKVILLE, Md., Nov. 4, 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 September 30, 2020, and recent operational highlights.

"We have made several important advancements in our clinical pipeline during the third quarter of 2020, with continued focus on execution during the COVID-19 pandemic. I'm pleased that two Phase II trials are underway for the treatment of wet AMD and diabetic retinopathy using the suprachoroidal approach for the delivery of RGX-314. In addition, we have expanded our RGX-121 program for patients with MPS II to gain additional insight into the potential treatment effects of this one-time gene therapy candidate in more patients, and we have dosed additional patients in the second cohort of the ongoing Phase I/II trial. I look forward to providing additional updates on all of our clinical programs in 2021, as we continue to focus on the significant unmet medical needs in both large indications and rare diseases," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO.

"The overall progress of gene therapy treatments continues to be encouraging, as we see additional patients around the world treated with Zolgensma^®, the first approved gene therapy based on REGENXBIO's NAV Technology Platform," continued Mr. Mills. "We maintain our focus on our important relationships with partners and licensees in the gene therapy space, with a strong focus on patient needs and innovative approaches to treat disease."

Marketed NAV Technology Product Highlights

REGENXBIO's NAV Technology Platform is being applied in one marketed product, Zolgensma. On October 27, 2020, Novartis AG reported third quarter 2020 global Zolgensma sales revenue of $291 million, and REGENXBIO recognized royalty revenue of $18.8 million in the third quarter of 2020 as a result of these sales. Novartis AG has recorded over $1.0 billion in cumulative net sales of Zolgensma since launch in 2019.

Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $289.8 million as of September 30, 2020, compared to $400.0 million as of December 31, 2019. The decrease was primarily attributable to net cash used in operating activities of $93.5 million and cash used to purchase property and equipment of $14.0 million. Cash, cash equivalents and marketable securities reported as of September 30, 2020 excludes the $80.0 million milestone payment received from Novartis AG in October 2020, which was recorded as accounts receivable as of September 30, 2020.

Revenues: Revenues were $98.9 million for the three months ended September 30, 2020, compared to $14.7 million for the three months ended September 30, 2019. The increase was primarily attributable to a $9.6 million increase in Zolgensma royalty revenue for the third quarter of 2020 as compared to the third quarter of 2019, as well as an $80.0 million milestone fee recognized as revenue in the third quarter of 2020 upon the achievement of $1.0 billion in cumulative net sales of Zolgensma. Net sales of Zolgensma for the third quarter of 2020 increased by 82% as compared to the third quarter of 2019.

Research and Development Expenses: Research and development expenses were $44.0 million for the three months ended September 30, 2020, compared to $35.7 million for the three months ended September 30, 2019. The increase was primarily attributable to personnel-related costs as a result of increased headcount, 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 $15.9 million for the three months ended September 30, 2020, compared to $12.4 million for the three months ended September 30, 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 Income (Loss): Net income was $8.8 million, or $0.24 basic and $0.23 diluted net income per share, for the three months ended September 30, 2020, compared to net loss of $34.6 million, or $0.94 basic and diluted net loss per share, for the three months ended September 30, 2019. Net income for the three months ended September 30, 2020 includes a non-cash charge of $7.7 million for a provision for credit losses recognized related to accounts receivable during the period.

Financial Guidance

Based on its current operating plan, REGENXBIO expects its balance in cash, cash equivalents and marketable securities of $289.8 million as of September 30, 2020, in addition to the $80.0 million received from Novartis AG in October 2020, to fund its operations, including the completion of its internal manufacturing capabilities and clinical advancement of its product candidates, until mid-2022.
