Selecta Biosciences Announces Fourth Quarter and Year End 2018 Financial Results and Provides Corporate Update

March 15, 2019

-- Phase 2 head-to-head (COMPARE) clinical trial of SEL-212 vs. KRYSTEXXA® to begin in 1Q19, interim six-month data expected in 4Q19 -- Collaboration with CureCN projected to dose first patient with combination of ImmTOR + AAV gene therapy candidate in 2H19 -- Company raises $33M in gross offering proceeds and $31.3M in net proceeds in 1Q19, cash runway into 1Q20 -- Company to host conference call today at 8:30 a.m. ET

WATERTOWN, Mass., March 15, 2019 (GLOBE NEWSWIRE) -- Selecta Biosciences, Inc. (Nasdaq: SELB), a clinical-stage biotechnology company focused on unlocking the full potential of biologic therapies based on its immune tolerance platform technology, ImmTOR, today reported financial results for the fourth quarter and full year ended December 31, 2018 and provided a corporate update.

“During 2018 we laid a strong groundwork for a year of execution in 2019. We kicked off the year by streamlining the company through a corporate restructuring, which is projected to cut our cash burn rate by 19%. We then completed an equity fundraise of approximately $33 million in gross proceeds and $31.3 million in net proceeds, and anticipate reporting key milestones for both our chronic refractory gout and gene therapy programs. We continue to believe that our lead program, SEL-212, has the potential to address several unmet needs in chronic refractory gout patients, including sustained serum uric acid reduction, reduced painful flares and once monthly dosing, and we look forward to initiating the planned six-month head-to-head (COMPARE) clinical trial against Krystexxa this month,” said Carsten Brunn, Ph.D., President and CEO of Selecta. “We also look forward to further advancing our ImmTOR + AAV gene therapy combination product candidate in Crigler-Najjar Syndrome in collaboration with CureCN in the second half of the year and identifying other ways to advance our ImmTOR platform and grow our strategic partnerships.”

2018 and Recent Highlights and Anticipated Upcoming Milestones

SEL-212 (ImmTOR+Pegadricase) for the Treatment of Chronic Refractory Gout:

-- Six-Month Head-to-Head (COMPARE) Clinical Trial of SEL-212 vs. Krystexxa Expected to Begin in 1Q19:Selecta expects to initiate a Phase 2 head-to-head (COMPARE) clinical trial of SEL-212, compared to the current FDA-approved uricase therapy, Krystexxa, in the first quarter of 2019. An interim six-month data readout is projected for the fourth quarter of 2019, with a full statistical data analysis expected in the first quarter of 2020. The results of the COMPARE trial are expected to inform the design of the planned Phase 3 clinical trial of SEL-212, which the company plans to initiate in the fourth quarter of 2019. -- Reported Phase 2 Data:Selecta has reported data from its Phase 2 trial showing that 66% of evaluable patients (21/32), maintained serum uric acid (sUA) levels of <6mg/dL after five once-monthly treatments of SEL-212 at doses of 0.1 or 0.15 mg/kg of ImmTOR in combination with 0.2mg/kg of pegadricase. Furthermore, reduced total urate burden and lowered flare rates and severity were observed in the Phase 2 clinical trial, and SEL-212 continued to be generally well tolerated.

AAV Gene Therapy Program:

-- Collaboration with CureCN Consortium Projected to Dose First Patient in 2H19:In September 2018, Selecta announced a collaboration with CureCN, a European consortium, for an ImmTOR+AAV gene therapy combination product candidate in Crigler-Najjar Syndrome, building upon preclinical work that was published together with Genethon in Nature Communications in October 2018. Selecta expects CureCN to initiate preclinical toxicology studies in the first half of 2019 and for the combination product candidate to enter the clinic in the second half of 2019.

Corporate Updates:

-- Corporate Restructuring Completed in January 2019:Selecta completed a corporate restructuring that reduced the company’s workforce by 36 percent as of January 3, 2019. This reduction, coupled with a reprioritization of the company’s pipeline programs, is projected to reduce the yearly cash burn by 19 percent. -- Successfully Completed a $33.3 Million Public Offering; Providing Cash Runway into 1Q20:In January 2019, Selecta completed an underwritten public offering of 22,188,706 shares of its common stock, at a price to public of $1.50 per share, resulting in net proceeds to Selecta of $31.3 million, after deducting underwriting discounts and commissions. -- Strengthened Management Team: Effective December 1, 2018, Carsten Brunn, Ph.D., assumed the role of President and CEO of Selecta, following his previous position as President of Pharmaceuticals for the Americas Region and member of the Global Pharmaceutical Executive Committee at Bayer.

Fourth Quarter 2018 Financial Results:

-- Revenue:For the fourth quarter of 2018, the company recognized $0.9 million of revenue, which compares to less than $0.1 million for the fourth quarter of 2017. The increase resulted from an increase in grant revenue and was the sole result of the conclusion of the company’s grant with NIDA. -- Research and Development Expenses: Research and development expenses for the fourth quarter of 2018 were $10.3 million, which compares with $13.6 million for the fourth quarter of 2017. The decrease was driven by reduced expenditures for our preclinical product candidates combined with the winding down of the Phase 2 clinical trial of SEL-212 in the second half of 2018. -- General and Administrative Expenses:General and administrative expenses for the fourth quarter of 2018 were $5.1 million, which compares with $5.7 million for the fourth quarter of 2017. The reduction in costs was primarily the result of reduced consulting fees. -- Net Loss:For the fourth quarter of 2018, Selecta reported a net loss of $(14.7) million, or $(0.65) per share, compared to a net loss of $(19.5) million, or $(0.88) per share, for the same period in 2017. -- Cash Position: Selecta had $37.7 million in cash, cash equivalents and restricted cash as of December 31, 2018, which compares to cash, cash equivalents and short-term investments of $50.5 million at September 30, 2018. The company currently has a cash runway into the first quarter of 2020, which includes proceeds net of underwriting discounts and commissions of $31.3 million from the company’s recent follow-on offering in January 2019.
