DateStageInvestorsRaisedDeal Summary
Oct 2021Series BCancer Prevention and Research Institute of Texas (lead)$18MOncoNano Medicine, Inc., based in Southlake, Texas, develops pH-sensitive micelle nanotechnology for cancer imaging and therapeutics, including pegsitacianine (formerly ONM-100) for real-time tumor imaging during surgery and ONM-501 as an immune-therapeutic. On October 25, 2021, the Cancer Prevention and Research Institute of Texas (CPRIT) converted $18.4 million in prior grant awards into an equity investment, closing the company's Series B financing at a total of $68.4 million in committed capital. This followed an approximate $50 million Series B raise led by Advantech Capital, with CPRIT's contribution securing Texas' stake in the technology originating from UT Southwestern Medical Center research. Proceeds from the Series B, including CPRIT's equity infusion, supported clinical development of pegsitacianine toward pivotal trials in the U.S. and Europe, IND-enabling activities and first-in-human trials for ONM-501 targeted for early 2023, and expansion of operations in North Texas. Earlier CPRIT grants included $6 million in 2014, $15.4 million in 2019 for ONM-500 (HPV-related cancers), and $9.97 million (noted in prior awards converted). Pegsitacianine held FDA Fast Track designation and was in Phase 2 trials at the time. CPRIT's involvement spanned multiple grants since 2014, reflecting its role in fostering Texas-based cancer innovation, with over $2.6-2.7 billion awarded across programs by 2021, recruiting researchers, and generating additional investments.
Oct 2021Undisclosed stageSalem Partners (lead)$68MOncoNano Medicine, Inc. is a clinical-stage biopharmaceutical company developing pH-activated compounds for cancer imaging and therapeutics, including intraoperative imaging agent pegsitacianine (ONM-100) and immune-therapeutic ONM-501. The company leverages its pH-sensitive micelle platform to target disease microenvironments. Prior to 2021, OncoNano raised $35.4M in Series A financing in 2018-2019, arranged and participated in by Salem Partners, to support clinical trials and platform expansion, supplemented by a $6M CPRIT grant. In 2021, Salem Partners served as exclusive financial advisor for OncoNano's $68.4M Series B funding round. Separately, OncoNano announced ~$50M in Series B financing on June 17, 2021, led by Advantech Capital, with funds for Phase 3 trials of pegsitacianine and IND-enabling activities for ONM-501. Other 2021 activity includes a $26.4M round on March 26 and multiple CPRIT grants (e.g., $18.4M Grant - IV, Oct 2021). OncoNano continued raising capital post-2021, reaching $166.28M total over 10 rounds by a Series C in June 2025, with focus on advancing clinical programs in cancer surgery and immuno-oncology.
Jun 2021Series BAdvantech Capital (lead); Adam Okun$50MOncoNano Medicine, Inc., a Southlake, Texas-based biotech spinout from University of Texas Southwestern, develops pH-activated micelle platform technology for cancer diagnostics and therapeutics. Its lead product, pegsitacianine (formerly ONM-100), is a real-time intraoperative imaging agent that illuminates cancerous tissue during surgical resection of solid tumors by reacting to low pH environments, enabling precise tumor removal. The company also advances ONM-501, a novel immuno-oncology compound and dual-activation STING agonist for therapeutic applications, with plans for IND submission and Phase 1a/1b trials. On June 17, 2021, OncoNano announced an approximate $50 million Series B financing round led by Advantech Capital's healthcare investment team, a China-based cross-border private equity fund focused on innovation-driven opportunities in pharmaceuticals and healthcare. Adam Okun participated alongside the lead investor. Funds were earmarked to initiate pivotal Phase 3 trials for pegsitacianine in the U.S. and Europe, support IND-enabling activities for ONM-501, and advance the platform toward commercialization, combined with prior Cancer Prevention & Research Institute of Texas (CPRIT) support to sustain operations for several years. The Series B later closed with an additional $18.4 million equity investment from CPRIT converting prior grant funding, bringing total committed capital to $68.4 million. This built on a prior Series A round totaling $35.4 million closed in 2019, led by Salem Partners, which funded Phase 1 trials for ONM-100 (showing 100% imaging response) and platform expansion into therapeutics and vaccines. Pegsitacianine received FDA fast-track designation.
Jul 2019Series ASalem Partners (lead)$24MOncoNano Medicine, Inc., a Southlake, Texas-based biotech company spun out from UT Southwestern, develops pH-activated compound platforms for cancer imaging and therapeutics. Its technology exploits the acidic tumor microenvironment using polymeric micelles like the ON-BOARD platform to deliver payloads precisely to tumor sites, improving pharmacokinetics for small molecules and biologics. Key products include ONM-100, an intraoperative cancer imaging agent that showed 100% imaging response in a Phase 1 trial, and expansions into cancer vaccines and therapeutics. The specified funding event on July 9, 2019, was the second tranche of $23.7 million in Series A financing arranged and participated in by Salem Partners, bringing the total Series A to $35.4 million after an initial $11.7 million tranche closed in May 2018. This supplemented a prior $6 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). Salem Partners acted as exclusive financial advisor and principal investor, with John Dyett joining the board. Proceeds funded ongoing cancer imaging clinical trials for ONM-100 and advanced the pH-sensitive micelle platform into therapeutics and vaccines. The company appointed industry leaders like Al Guillem as board chairman. OncoNano emphasized clinical momentum, targeting disease detection and treatment improvements. Later, OncoNano raised ~$50 million in Series B in 2021 led by Advantech Capital for Phase 3 trials of pegsitacianine (formerly ONM-100) and ONM-501 immuno-therapeutic, plus additional rounds totaling over $166 million by 2025.
May 2018Series ASalem Partners (lead)$12MOncoNano Medicine, Inc., a Southlake, Texas-based biopharmaceutical company, develops pH-activated compounds that exploit pH variability in diseases like cancer for targeted therapeutics and imaging agents. The company closed an $11.7 million Series A financing on May 17, 2018, arranged and principally invested by Salem Partners. This round supplemented a prior $6 million grant from the Cancer Prevention and Research Institute of Texas (CPRIT). Proceeds supported continued clinical development of its pH-activated platform, including ONM-100 for cancer surgeries. OncoNano appointed five industry leaders to its Board of Directors, including Al Guillem, Ph.D., as Chairman (former President of ZS Pharma), Ravi Srinivasan, Ph.D. (Founder and CEO), John Dyett (Salem Partners), and Paritosh Dhawale, Ph.D. (GE Healthcare). The financing highlighted momentum in the company's approach to disease targeting.
