(Nasdaq: QLGN), a biotechnology company focused on developing novel therapeutics for the treatment of cancer and viral diseases, today announced its financial results for the quarter ended March 31, 2021, and provided an update on its therapeutics pipeline and other corporate developments. The Company will present its first quarter 2021 financial results and operational highlights in a conference call on May 18, 2021 at 4:10 p.m. EDT. Highlights from the Quarter Ended March 31, 2021: “We were very pleased to see the improvement in our revenue growth during the first quarter from our FastPack® System. Despite the challenges of operating during the pandemic, we managed to safely stay open to manufacture and ship our FastPack immunoassay products to meet the needs of our valued Diagnostics customers,” stated Michael Poirier, Chief Executive Officer at Qualigen Therapeutics, Inc. He added: “While we are maintaining our diagnostics business, we are also working diligently to develop our therapeutics pipeline, which includes QN-165, QN-247, RAS-F, and STARS™.” “We continue to strengthen our team with proven pharmaceutical professionals who leverage their knowledge and experience in order for us to achieve important milestones with each of our pipeline programs,” stated Amy Broidrick, EVP, Chief Strategy Officer. Pipeline and Corporate Highlights Made significant progress with the IND-enabling studies for Qualigen’s lead candidate, QN-165, which is a broad-spectrum antiviral drug candidate for treating COVID-19 and other viral-based infectious diseases. Completed the R&D evaluation and qualification for QN-247, a DNA coated gold nanoparticle cancer drug candidate that has the potential to target various types of cancer with minimal side effects. The nanoparticle coating technology is similar to the core nanoparticle coating technology used in Qualigen’s blood-testing diagnostic products. Continued our license and sponsored research agreements with the University of Louisville to evaluate the use of QN-247 with G-quadruplex binders. Qualigen plans to seek to obtain Orphan Drug status for QN-247 for one or more indications, such as pancreatic cancer, acute myeloid leukemia and pediatric neuroblastoma. Orphan Drug status, if obtained, would be expected to confer several advantages including faster review and increased market protection. Entered into a Material Evaluation and Option Agreement with the University College London (UCL) which will allow Qualigen to study a significant potential indication for QN-247 with improved selectivity for pancreatic cancer cells. In addition to the pancreatic cancer treatment indication, Qualigen will also continue to evaluate QN-247 to treat leukemia and glioblastoma, and as an adjuvant therapy to stop the recurrence of cancer after initial treatment. Qualigen’s patent portfolio for therapeutics now has 37 owned or in-licensed patents and patent applications covering the QN-247 and/or QN-165 programs, 26 of which are issued. First Quarter 2021 Financial Highlights Revenues in the three months ended March 31, 2021 were $1.9 million compared to $1.5 million during the three months ended March 31, 2020, an increase of $0.4 million. Our operating revenues are primarily generated from sales of diagnostic tests. This increase was primarily due to recognition of license revenue from Yi Xin Duan Jishu (Suzhou) Ltd. under our agreement with them for FastPack in China. Net product sales remained level at approximately $1.4 million during the three months ended March 31, 2021 and 2020, but improved compared to the later 2020 quarters which were negatively impacted by the COVID-19 pandemic. License revenue during the three months ended March 31, 2021 was approximately $479,000, due to the recognition of revenue from the Yi Xin transaction. General and administrative expenses increased to $2.9 million during the three months ended March 31, 2021 from $0.9 million during the three months ended March 31, 2020. This increase was primarily due to overhead expenses related to our public-company status in the three months ended March 31, 2021 in contrast to our private-company status in the three months ended March 31, 2020. As of March 31, 2021, Qualigen Therapeutics had $21.9 million of cash and cash equivalents.

About Qualigen Therapeutics, Inc. Qualigen Therapeutics, Inc. is a biotechnology company focused on developing novel therapeutics for the treatment of cancer and infectious diseases, as well as maintaining and expanding its core FDA-approved FastPack® System, which has been used successfully in diagnostics for 20 years. Our cancer therapeutics pipeline includes QN-247 (formerly referred to as ALAN or AS1411-GNP), RAS-F and STARS™. QN-247 is a DNA coated gold nanoparticle cancer drug candidate that has the potential to target various types of cancer with minimal side effects; the nanoparticle coating technology is similar to the core nanoparticle coating technology used in our blood-testing diagnostic products. The foundational aptamer of QN-247, QN-165 (formerly referred to as AS1411), is also a drug candidate for treating COVID-19 and other viral-based infectious diseases; we currently plan that our first clinical trial would be a trial of QN-165 against COVID-19. RAS-F is a family of RAS oncogene protein-protein interaction inhibitor small molecules for preventing mutated RAS genes’ proteins from binding to their effector proteins; preventing this binding could stop tumor growth, especially in pancreatic, colorectal and lung cancers. STARS is a DNA/RNA-based treatment device candidate for removal from circulating blood of precisely targeted tumor-produced and viral compounds. Because Qualigen’s therapeutic candidates are still in the development stage, Qualigen’s only products that are currently commercially available are FastPack System diagnostic instruments and test kits, used in physician offices, clinics and small hospitals around the world. The FastPack System menu includes rapid point-of-care diagnostic tests for cancer, men’s health, hormone function, and vitamin D status. Qualigen’s facility in Carlsbad, California is FDA and ISO Certified and its FastPack product line is sold worldwide by its commercial partner Sekisui Diagnostics, LLC.
