The biotechnology industry is characterized by rapidly advancing technologies as well as a strong emphasis on intellectual property leading to a highly competitive environment for the development and commercialization of therapeutic products,regenerative medicines, and vaccines. We face competition with respect to our current product candidates and will face competition with respect to any product candidates that we may seek to develop or commercialize in the future. We face competition from many different sources, including from major pharmaceutical companies, specialty pharmaceutical companies, biotechnology companies, academic institutions, government agencies, and other public and private research organizations that conduct research, seek patent protection, and establish collaborative arrangements for research, development, manufacturing, and commercialization.
The development and commercialization of gene therapies is highly competitive. We are aware of several companies focusing on gene therapies for various ophthalmic indications including Applied Genetic Technologies Corporation, as acquired by Syncona Limited, Astellas Pharma Inc., MeiraGTx Holdings plc in partnership with Janssen Pharmaceuticals, Inc., Nanoscope Therapeutics Inc., REGENXBIO Inc., Novartis AG, F. Hoffmann-La Roche AG ("Roche AG"), Kiora Pharmaceuticals, Inc., Genentech, Inc. in partnership with Lineage Cell Therapeutics, Inc., and Luxturna, the product developed by Spark Therapeutics, Inc. and marketed by Roche AG, is currently the only gene therapy approved to treat IRDs in the United States which addresses only mutations in the RPE65 gene. The mutation associated with the RPE65 gene represents just one of more than 125 mutated genes linked to RP and LCA.
The regenerative medicine sector is characterized by innovative science, rapidly advancing technologies, and a strong emphasis on proprietary products. The competitive landscape in the field of articular cartilage repair in the U.S. is emerging and has stimulated a substantial amount of interest from companies developing tissue repair solutions. Companies that may compete with our NeoCart product candidate include Vericel Corporation's MACI, the only FDA-approved ACI product in the United States, and Aesculap Biologics, LLC's NOVOCART 3D, which is currently enrolling subjects in their Phase 3 clinical trial.
We face, and will continue to face, intense competition from companies as well as institutions that are pursuing or have commercialized vaccines that would compete with our inhaled mucosal vaccine platform, if commercialized. The competitive landscape of COVID-19 vaccines has been rapidly developing since the beginning of the COVID-19 pandemic and includes competitors such as Pfizer Inc./BioNTech SE, Moderna, Inc., AstraZeneca PLC, Novavax, Inc., Sinovac Biotech Ltd., Gamaleya Research Institute of Epidemiology and Microbiology, and Center for Genetic Engineering and Biotechnology. Each of the aforementioned vaccines have been authorized or approved in at least one country within the Ocugen Mucosal Vaccine Territory and are intramuscular vaccines. CanSinoBIO's Convidecia Air, an intranasal vaccine targeting COVID-19, has been approved in China. Other competitors for our novel inhaled mucosal vaccine platform include CyanVac LLC, Meissa Vaccines, Inc., Codagenix, Inc., Intravacc B.V., McMaster University, and Tetherex Pharmaceuticals Corporation. Companies such as Pfizer Inc./BioNTech SE, Moderna, Inc., CureVac N.V in partnership with GSK plc, Vivaldi Biosciences Inc., and Novavax, Inc. are also in the process of developing a combination vaccine that will protect against COVID-19 and the seasonal flu. Vivaldi Biosciences Inc. is also currently undergoing clinical trials for their intranasal vaccine for the seasonal flu.
The development and commercialization of biologic products is highly competitive as well. Companies that may compete with our OCU200 product candidate include Roche AG, Regeneron Pharmaceuticals, Inc., AsclepiX Therapeutics, Inc., Outlook Therapeutics, Inc., Novartis AG, Oxurion NV, Unity Biotechnology, Inc., Opthea Limited, and 4D Molecular Therapeutics, Inc. Roche AG, Regeneron Pharmaceuticals, Inc., and Novartis AG have marketed anti-VEGF products.
Our commercial opportunities could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop and for which we receive approval. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our product candidates, which could result in our competitors establishing a strong market position before we are able to enter the market. They may obtain patent protection or other intellectual property rights that allow them to develop and commercialize their products before us and could limit our ability to develop or commercialize our product candidates.
In addition, our ability to compete may be affected in many cases by insurers or other third-party payors' coverage decisions, particularly Medicare, seeking to encourage the use of generic or biosimilar products. Many of the products that will compete with our product candidates, if approved, are available on a generic basis, and our product candidates may not demonstrate sufficient additional clinical benefits to clinicians, patients, or payors to justify a higher price compared to generic products. Additional competing products are expected to become available on a generic basis over the coming years.
Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals, and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.
