Atea Pharmaceuticals Inc. has been quietly developing a pipeline of oral direct-acting antiviral drugs against hepatitis C and other RNA viruses since 2014, but now the company has emerged from stealth mode with a $215m series D venture capital round and a lead development program designed to prevent moderate COVID-19 patients from turning into severe cases requiring mechanical ventilation.
Lead series D investor Bain Capital Life Sciences and the company’s many other backers are investing in Atea’s purine nucleotide prodrug platform as well as its management team, which boasts significant experience in developing antivirals. Founder, chairman and CEO Jean-Pierre Sommadossi was the principal founder of Idenix Pharmaceuticals Inc. and a co-founder of Pharmasset Inc. – two pioneers in the field of direct-acting antiviral (DAA) therapies against the hepatitis C virus.
Merck & Co. Inc. bought Idenix for $3.85bn in 2014 and Gilead Sciences Inc. bought Pharmasset – gaining the blockbuster drug and HCV backbone therapy Sovaldi (sofosbuvir) – for $11bn in 2012. (Also see "Merck in $3.85bn Idenix buy to bolster hep C outlook" - Scrip, 9 Jun, 2014.)
Atea’s series D round also was supported by new investors RA Capital Management, Perceptive Advisors, Rock Springs Capital, Adage Capital Management, funds and accounts managed by T. Rowe Price Associates Inc., Redmile Group and Omega Funds. Existing investors Morningside Ventures, Cormorant Asset Management, Ally Bridge Group, Sectoral Asset Management and others also participated.
The company announced the financing on 20 May and said it will begin a Phase II clinical trial soon for AT-527, its antiviral against COVID-19, since the US Food and Drug Administration recently approved an investigational new drug (IND) application for the study. The trial will test AT-527 in adult patients hospitalized for moderate COVID-19 who have at least one risk factor for poor outcomes in an effort to stop the disease from progressing to a severe condition that requires more intensive treatment.
The oral DAA is designed to inhibit the RNA polymerase enzyme, which should block replication of SARS-CoV-19, the novel coronavirus that causes the disease COVID-19. Preclinical studies have shown that AT-527 can stop the replication of RNA viruses, including human coronaviruses and flaviviruses; the drug candidate has shown antiviral activity and safety in a Phase II study in HCV.
Atea also will use its series D proceeds to fund other antiviral development programs, including AT-527 in HCV, as well as AT-777 and a fixed-dose combination of the two candidates for HCV. Two earlier-stage antiviral programs for dengue virus and respiratory syncytial virus also are in development.
The company joins a growing list of biopharmaceutical firms raising big money for COVID-19 treatments and vaccines, such as Moderna Inc., which brought in $1.34bn in a public offering of common stock after reporting early results for its messenger RNA (mRNA)-based vaccine on 18 May.
Also, AstraZeneca PLC said on 20 May that it entered into an agreement to receive more than $1bn from the Biomedical Advanced Research and Development Authority (BARDA), part of the office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services, to fund manufacturing and delivery of global volumes of its vaccine in development with Oxford University. (Also see "Coronavirus Update: AZ Gets $1bn From US, Secures Capacity For One Billion Vaccine Doses" - Scrip, 21 May, 2020.)
A day earlier, Richmond, VA-based drug manufacturer Phlow revealed that it won a contract from BARDA worth up to $812m, including $354m in initial funding over a four-year period to support manufacturing of essential medicines, including drugs to treat COVID-19.
The goal of the Phlow/BARDA partnership is to ensure production of commonly used drugs that are at risk of supply shortages due to business disruptions around the world caused by the pandemic and increased demand for medicines used to treat COVID-19 patients. Phlow has started manufacturing chemical precursor ingredients, active pharmaceutical ingredients and finished drugs for more than a dozen essential medicines use to treat patients hospitalized with COVID-19. (Also see "COVID-19 Funds Flow To Startup In Bid To Restore US Pharmaceutical Manufacturing" - Pink Sheet, 20 May, 2020.)
The BARDA funding will help Phlow and its other partners add 1.6m doses of five essential generic medicines to the Strategic National Stockpile; these include antibiotics as well as drugs used to sedate patients on ventilators and to manage pain. (Also see "US Plows $354m Into Phlow" - Generics Bulletin, 20 May, 2020.)
Cowen Healthcare Investments (CHI), a division of the investment banking firm Cowen Inc., said on 19 May that it raised $493m for Cowen Healthcare Investments III LP, bringing in $93m more than planned for its third fund backing biopharma, diagnostic and digital health investments.
New York-based CHI said it is focused on “established companies with outstanding management teams and disruptive approaches to disease that address significant unfulfilled medical needs.” CHI has put its money behind 38 private health care companies since 2012.
CHI joins a long and growing list of investment firms that have announced new biopharma investment funds during the COVID-19 pandemic, including Flagship Pioneering and ARCH Venture Partners, which each raised more than $1bn for their respective funds supporting start-ups and early-stage companies. (Also see "Flagship, ARCH Close VC Funds Totaling $2.56bn" - Scrip, 2 Apr, 2020.)
San Diego-based Amplyx Pharmaceuticals Inc. announced on 18 May that it extended its series C financing to $93m. The antifungal developer revealed the first closing of its series C round in 2017 totaling $67m. That initial sum included $40m in a first tranche, but in 2020 the company received the final second $27m tranche and an additional $26m. (Also see "Amplyx Raises $67m For Antifungals Against Life-Threatening Pathogens" - Scrip, 2 Aug, 2017.)
Amplyx also revealed on 18 May that it has completed enrollment in a Phase II clinical trial testing lead drug candidate fosmanogepix (APX001) for the treatment of infections caused by Candida, with top-line results expected by July. The company also has treated the first few patients in two other trials testing fosmanogepix to treat invasive mold infections caused by Aspergillus and rare molds and invasive candidiasis caused by Candida auris. (Also see "Amplyx Cleared To Complete Phase II Study Of New Antifungal Class" - Scrip, 16 Sep, 2019.)
Pfizer Inc. and Adage Capital Management are new investors in Amplyx via the series C extension led by Sofinnova Investments with participation from existing investors, including New Enterprise Associates, Lundbeckfonden Ventures, Arix Bioscience, Pappas Capital, RiverVest Venture Partners, 3×5 Partners and BioMed Ventures.
The proceeds will fund clinical development of fosmanogepix and MAU868, a monoclonal antibody for the treatment of BK virus (BKV) infections in people who have received a kidney or hematopoietic stem cell transplant; a Phase II BKV trial is planned. Fosmanogepix has fast track, orphan drug and Qualified Infectious Disease Product (QIDP) designations from the US FDA.
Palo Alto, CA-based Kriya Therapeutics said on 12 May that it raised an $80.5m series A round to fund the development of gene therapies for highly prevalent diseases. The company was founded in the fourth quarter of 2019 by former executives from Spark Therapeutics Inc., AveXis Inc., Sangamo Therapeutics and other gene therapy companies, who have partnered with various academic institutions and other pioneers in the field. Transhuman Capital provided seed funding for Kriya and invested in the company’s series A round along with QVT, Dexcel Pharma, Foresite Capital, Bluebird Ventures (associated with Sutter Hill Ventures), Narya Capital, Amplo, Paul Manning and Asia Alpha. Kriya hopes to extend the benefit of one-time gene therapies beyond monogenic rare diseases. The company’s initial AAV-based gene therapy programs include KT-A112, which delivers genes to produce insulin and glucokinase for type 1 and type 2 diabetes; KT-A522, which delivers the gene to produce a glucagon-like peptide 1 (GLP-1) receptor agonist for type 2 diabetes and severe obesity; and KT-A832, which delivers the gene to produce modified insulin growth factor 1 (IGF-1) for type 1 diabetes.
Nautilus Biotechnology in San Carlos, CA, said on 21 May that it has raised more than $100m to date, including its recently completed $76m series B financing, to further develop its high-throughput, low-cost platform for analyzing and quantifying the human proteome – the entire set of proteins involved in human physiology. Nautilus said its platform can accelerate basic science research, improve the success rate of therapeutic development and speed the adoption of personalized and predictive medicine. Biopharma companies of all sizes are trying to exploit the human proteome to improve drug development success rates, including Amgen Inc. (Also see "Amgen’s R&D Group Focuses On Efficiency As Drug Cost Concerns Continue" - Scrip, 29 Jan, 2020.) However, the Nautilus series B round was supported largely by high-tech investors; Vulcan Capital, the investment arm of Microsoft co-founder and philanthropist Paul G. Allen’s Vulcan Inc., led the round with participation from new investors Perceptive Advisors, Bezos Expeditions and Defy Partners as well as prior investors AME Cloud Ventures, Andreessen Horowitz, Bolt and Madrona Venture Group.
Boston-based HotSpot Therapeutics Inc. said on 21 May that it completed a $65m series B round led by GlaxoSmithKline PLC’s corporate VC arm SR One with participation from funds managed by Tekla Capital Management, MRL Ventures Fund, Solasta Ventures and Brace Pharma (via affiliate Cleva Pharma) plus co-founding investors Atlas Venture and Sofinnova Partners. HotSpot raised a $45m series A round in 2018 to fund its development of allosteric medicines that target regulatory hotspots that are located remote from the active site on a protein, but are used by nature to control protein function. (Also see "Finance Watch: A Plethora Of Big Rounds, Led By Gossamer's $230m Series B" - Scrip, 31 Jul, 2018.) The company is developing small molecules for the treatment of autoimmune conditions, rare diseases and cancer. Its SpotFinder platform has identified regulatory hotspots across multiple target classes, including kinases, transcription factors and E3 ligases. HotSpot has developed the first-ever allosteric inhibitors of protein kinase C (PKC-theta) in autoimmune diseases and S6 kinase for rare metabolic disease.
SQZ Biotechnologies Co. in Watertown, MA, completed a $65m series D preferred stock financing led by Temasek with participation from an unidentified large US-based fund. SQZ said on 18 May that prior investors – including GV, Illumina Ventures, Invus, JDRF T1D Fund, NanoDimension and Polaris Partners – also backed the series D financing. The company’s cellular vaccine platform is being tested in a Phase I study enrolling patients with HPV-positive cancers, but SQZ also will use the series D proceeds to advance its technology in the treatment of infectious diseases and to develop a point-of-care system for generating the patient-specific therapies. The company’s off-site production of autologous therapies for its cancer study currently takes less than 24 hours. In infectious diseases, SQZ intends to develop treatment and prophylaxis for chronic infections and novel viruses. The company raised a $72m series C round in 2018.
