"2019 was a pivotal year for Selecta. We made substantial clinical advancements, as we completed enrollment in the head-to-head COMPARE trial for our lead product candidate, SEL-212, in chronic refractory gout, and advanced our gene therapy program through strategic partnerships with AskBio. We also strengthened our organization with the addition of several key members to the executive team and welcomed a new Chairman of our Board of Directors, and completed a $70 million financing," said Carsten Brunn, Ph.D., President and CEO of Selecta. "In the coming year, we look forward to reporting topline data from the COMPARE study, commencing the Phase 3 clinical program of SEL-212, and advancing our gene therapy program into the clinic in partnership with AskBio."

Recent Highlights and Anticipated Upcoming Milestones:

Topline Results from COMPARE Clinical Trial Expected in the Third Quarter of 2020: In December 2019, we announced the completion of enrollment in the head-to-head COMPARE study of Selecta’s lead product candidate, SEL-212 (ImmTOR + pegadricase), vs. pegloticase. Topline data from this trial is expected in the third quarter of 2020. The trial is evaluating a once-monthly dose of SEL-212 compared to biweekly doses of pegloticase, with the primary endpoint of the maintenance of serum uric acid (SUA) levels of <6mg/dL at three and six months.

Meeting with FDA Provides Clarity on Phase 3 Clinical Program of SEL-212: Selecta held a meeting with the U.S. Food and Drug Administration (FDA) in January 2020 to inform the design of the planned Phase 3 clinical program. Selecta plans to commence its Phase 3 clinical program of SEL-212 against placebo in the second half of 2020.

Gene Therapy Program in the Clinic by the End of 2020: In August 2019, Selecta announced a strategic partnership with Asklepios BioPharmaceutical, Inc. (AskBio), to jointly develop, manufacture, and commercialize a broad portfolio of next-generation AAV gene therapies. This

partnership will leverage the unique proprietary technology platforms of both companies with a human proof of concept trial to validate this portfolio of products and their potential for re-dosing in patients, which could represent a significant advancement in the gene therapy field. Selecta and AskBio anticipate entering the clinic by the end of 2020. Additionally, the Company intends to advance its proprietary program in ornithine transcarbamylase (OTC) deficiency.

Broadened Strategic Partnership with AskBio: In December 2019, Selecta and AskBio jointly announced that the companies entered into a license agreement under which AskBio exercised its option to exclusively license rights to develop and commercialize Selecta’s immune tolerance platform, ImmTOR, for use in adeno-associated virus (AAV) gene therapy for the treatment of Pompe disease. Affecting 5,000-10,000 people worldwide, Pompe disease is a rare, genetic, lysosomal storage disease characterized by the abnormal buildup of a sugar molecule called glycogen inside cells. Under the terms of the agreement, Selecta received upfront payments of $7 million and is eligible to receive milestone payments of $237 million plus royalties on product sales.

Raised $70 Million in a Private Placement: In December 2019, Selecta announced the closing of a transaction to sell securities in a private placement with institutional investors and certain members of the Company’s Board of Directors, resulting in gross proceeds of approximately $70 million.

Strengthened Board of Directors: In November 2019, Selecta announced the appointment of Carrie S. Cox to the position of Chairman of the Board of Directors. A renowned industry leader and successful biopharmaceutical executive, Ms. Cox has served on multiple Boards, and has held the position of Chair, for several biopharmaceutical companies.

Fourth Quarter and Full Year 2019 Financial Results:

Cash Position: Selecta had $91.6 million in cash, cash equivalents, and restricted cash as of December 31, 2019, which compares to cash, cash equivalents, restricted cash, and short-term investments of $35.9 million as of September 30, 2019. Selecta believes its available cash, cash equivalents, and restricted cash will be sufficient to meet its operating requirements into the first quarter of 2021.

Net cash used in operating activities was $12.9 million and $51.4 million for the fourth quarter and fiscal year 2019, respectively, as compared to $12.7 million and $59.2 million for the same periods in 2018.

Research and Development Expenses: Research and development expenses for the fourth quarter and fiscal year 2019 were $15.2 million and $42.7 million, respectively, which compares with $10.3 million and $47.7 million for the same periods in 2018. The quarterly increase reflects additional costs incurred specific to our Phase 2 head-to-head (COMPARE) clinical trial of SEL-212, for which we completed enrollment in December 2019. The decrease year over year reflects reduced costs in 2019 due to the completion of prior programs in 2018, combined with reduced salaries and benefits resulting from the headcount reduction in early 2019. The cost reductions were offset by an overall increase in costs incurred on our lead product candidate, SEL-212.

General and Administrative Expenses: General and administrative expenses for the fourth quarter and fiscal year 2019 were $4.1 million and $16.4 million, respectively, which compares with $5.1 million and $18.2 million for the same periods in 2018. The decrease is the result of lower salaries and stock compensation expense resulting from reduced headcount at the end of 2018, combined with reduced patent and professional fees.

Net Loss: For the fourth quarter and fiscal year 2019, Selecta reported a net loss of $14.9 million, or $0.28 per share and $55.4 million, or $1.22 per share, compared to a net loss of $14.7 million, or $0.65 per share, and $65.3 million, or $2.92 per share, for the same periods in 2018.

Nurix Therapeutics Closes $120 Million Financing to Advance Targeted Protein Modulation Drug Pipeline

On March 12, 2020 Nurix Therapeutics, Inc., a company developing targeted protein modulation drugs, reported it has closed an oversubscribed $120 million financing (Press release, Nurix Therapeutics, MAR 12, 2020, View Source [SID1234555461]). The round was led by Foresite Capital with participation from Bain Capital Life Sciences, Boxer Capital (Tavistock Group), EcoR1 Capital, Redmile Group, Wellington Management Company and an undisclosed investor, as well as Nurix’s founding investors The Column Group and Third Rock Ventures.

"With the funds raised in this financing, Nurix is well positioned to bring its targeted protein modulation therapeutics into the clinic," said Arthur Sands, M.D., Ph.D., chief executive officer of Nurix Therapeutics. "We will also continue to use our powerful DELigase platform to discover new therapies aimed at previously undruggable targets of high therapeutic potential."

Proceeds from the financing will enable the company to advance Nurix’s wholly owned development candidates into clinical development. The leading edge of Nurix’s pipeline includes an orally delivered BTK chimeric targeting molecule (CTM) for B cell malignancies for which the Company expects to file an IND application with the FDA by the end of the year. The second molecule in Nurix’s preclinical pipeline is an orally delivered inhibitor of the CBL-B ligase for stimulation of T cell activation and IL-2 secretion as a novel immuno-oncology agent. Both development candidates were derived from Nurix’s DELigaseTM targeted protein modulation platform, which combines the use of DNA-encoded libraries (DEL) with an expanding set of E3 ligases to achieve targeted protein modulation. Nurix’s scientific approach enables either the harnessing of E3 ligases to degrade specific target proteins, as in the case of the BTK CTM, or the inhibition of specific ligases to raise substrate protein levels, as in the case of the CBL-B inhibitor.

"Nurix’s CTM and DELigaseTM platform technologies have led to the discovery of novel BTK degraders with the potential to transform the treatment landscape for hematological indications," said Michael Rome, Ph.D., partner at Foresite Capital. "Their differentiated platform and novel approach have resulted in strategic corporate partnerships and we believe position the company as a leader in the emerging protein modulation field."

In addition to advancing its wholly owned pipeline, Nurix recently formed two new strategic collaborations with Sanofi and Gilead to develop novel protein degradation therapies in multiple therapeutic areas. Together, these collaborations provided Nurix with $100 million in upfront payments and the potential for over $4.5 billion in milestones with additional royalties and certain co-development options.

About Mavorixafor
Mavorixafor is an investigational, oral, targeted therapy that antagonizes the chemokine receptor CXCR4 via allosteric inhibition. The CXCR4 receptor plays a key role in enabling the trafficking of immune cells and effective immunosurveillance. Over-stimulation of CXCR4 results in various immune-system deficiencies. X4 Pharmaceuticals is currently investigating mavorixafor as a once-daily treatment in a global Phase 3 pivotal trial in patients with WHIM syndrome, a rare, inherited, primary immunodeficiency disease caused by genetic mutations in the CXCR4 receptor gene. The FDA has granted Breakthrough Therapy Designation to mavorixafor for the treatment of WHIM syndrome. Mavorixafor is being developed in two proof-of-concept Phase 1b clinical trials – as monotherapy in patients with Severe Congenital Neutropenia (SCN), a group of rare blood disorders characterized by abnormally low levels of white blood cells, and in combination with ibrutinib in patients with Waldenström’s macroglobulinemia, a form of non-Hodgkin’s lymphoma, who have acquired mutations in the CXCR4 receptor.
