Tucson, Arizona, UNITED STATES TUCSON, Ariz., May 10, 2023 (GLOBE NEWSWIRE) -- HTG Molecular Diagnostics , Inc. (Nasdaq: HTGM) (HTG), a platform-based life science tools and drug discovery company, today reported financial results for the quarter ended March 31, 2023 and provided recent drug discovery business highlights. HTG has pioneered a proprietary platform-based approach that is designed to help improve drug discovery, referred to as transcriptome-informed drug discovery and design. At the center of this approach is the application of HTG’s proprietary RNA profiling technologies, functionally married with advanced medicinal chemistry using a novel artificial intelligence (“AI”)-driven platform. This unique drug candidate optimization platform is expected to allow for more biologically-relevant insight into drug candidate selection and design much earlier in the discovery process than in traditional drug discovery. HTG believes this approach will result in higher efficiency, improved risk management and cost efficiencies to bring novel drug candidate molecules from very early discovery through entry to development. HTG achieved three significant drug discovery business milestones in the first quarter of 2023 to advance the compounds for its first target and indication through lead optimization and to further strengthen its AI-driven drug discovery engine. First, HTG achieved in vitro demonstration of efficacy of its first lead compounds both as a standalone therapy and in combination with the current standard of care. The Company utilized its proprietary HTG EdgeSeq RNA profiling platform to biologically interrogate the lead molecules. This data, along with other primary and secondary data, was then introduced into the Company’s AI-driven drug discovery engine, resulting in the creation of a second generation of molecules. The second generation of molecules has been subjected to the same in vitro experiments as the first, demonstrating improved efficacy over the first generation of molecules. These results also demonstrate the utility of the AI-driven drug discovery engine in combination with high-quality full transcriptome data. Finally, the Company’s AI-driven drug discovery engine was used to design compounds using transcriptomic data as the starting point. These system-designed compounds showed highly similar characteristics to HTG’s lead compounds that were designed starting with the target. These results demonstrate the ability of HTG’s engine to design novel compounds based on transcriptomic data alone, which the Company believes will provide other opportunities for expanded platform applications, including drug repurposing. In addition to further advancing the Company’s drug discovery platform, these first quarter efforts have significantly advanced HTG's first oncology indication in liquid tumors through lead optimization studies and the Company expects that these efforts will support entry into preclinical development in the next several months. In addition, the Company's second target for the treatment of solid tumors has been selected and added to HTG’s oncology portfolio, which also includes an early pipeline in neurodegenerative diseases. “Through the diligent efforts of our strong and knowledgeable team, we have once again achieved extensive progress toward our strategy to establish our transcriptome-informed drug discovery process as the preferred methodology for small molecule drug discovery, complementing and expanding the advanced capabilities that our HTG EdgeSeq technology has provided for many years in profiling. The three major milestones reached by our team during the first quarter of 2023 have not only advanced and strengthened our AI-driven drug discovery engine, but have significantly advanced candidate molecules through lead optimization for our first indication in liquid tumors, with a program in solid tumors expected to follow closely behind,” said John Lubniewski, Chief Executive Officer and Director at HTG. Partnering discussions have been initiated with global biopharmaceutical companies around the Company's portfolio of drug candidate molecules in oncology and neurodegenerative disease indications. In addition, HTG has initiated partnering conversations regarding the use of HTG's drug discovery engine within the partners' portfolios of drug assets. “While our partnering discussions are in early stages, we are pleased with the level of preliminary interest we have seen in our drug discovery platform from pharmaceutical companies that historically in-license candidates for preclinical development as part of their business model as well as those interested in using our AI-driven drug discovery engine with their own target portfolios,” Mr. Lubniewski continued. “We believe this interest is driven by our highly differentiated approach to drug discovery, which uses our proprietary transcriptomic profiling technologies, integrated with a machine learning-based chemical library design platform, to better-inform the design and selection of drug candidate molecules. We believe that this approach will yield drug candidates with lower risk profiles and increased opportunities for development success, providing faster and more cost-efficient outcomes than traditional approaches, and believe that these potential partners are beginning to quickly understand these advantages.” First Quarter 2023 Financial Results: Product and product-related services revenue for the quarter ended March 31, 2023 was $1.0 million, compared to $1.2 million for the same period in 2022. This revenue continues to primarily reflect sales of the Company's two whole transcriptome products, the HTG Transcriptome and HTG EdgeSeq miRNA panels, to new and existing customers as consumables and sample processing services. Sales of these products represented 66% of revenue for the quarter ended March 31, 2023. Net loss from operations for the quarter ended March 31, 2023 was $5.0 million, compared to $6.3 million for the same period in 2022. Net loss per share was $(2.28) for the quarter ended March 31, 2023 compared with $(9.73) for the first quarter of 2022, reflecting approximately 1.3 million additional common shares issued in December 2022. This operating margin improvement also reflects cost reduction measures implemented in the second quarter of 2022 which aligned the Company's profiling cost structure with expected future revenue to reduce operating cash burn. Cash, cash equivalents and investments in available-for-sale securities totaled $6.6 million as of March 31, 2023, with current liabilities of approximately $6.6 million and non-current liabilities of $3.8 million.
