About ONM-501

ONM-501 is a next generation dual-activating STING (STimulator of INterferon Genes) agonist currently in phase 1 development for the treatment of solid tumors. STING activation mediates a multifaceted type-1 interferon response that is critical in the activation of innate and adaptive immunity against infection and, potentially, cancer. ONM-501 is a pH-sensitive polymer, PC7A, carrying a cyclic guanosine monophosphate–adenosine monophosphate (cGAMP) payload, that together induce prolonged STING activation. In preclinical models, when delivered to the tumor microenvironment, ONM-501 produces dendritic cell maturation and cytotoxic T cells priming, while demonstrating antitumor efficacy. ONM-501 is currently being evaluated in a phase 1, multicenter, open label, non-randomized dose escalation and dose expansion trial to examine the safety, pharmacokinetics, pharmacodynamics, and early activity of ONM-501 as a monotherapy and in combination with an anti-PD-1 checkpoint inhibitor, cemiplimab, in patients with advanced solid tumors and lymphomas. The trial is open in the United States and planned to open in Australia in 2H2024; visit clinicaltrials.gov (NCT06022029) for more details. ONM-501 development has been supported in part by a grant from the Cancer Prevention and Research Institute of Texas.

muONM-412 significantly improved tolerability over unencapsulated IL-12Fc and showed potent anti-tumor efficacy in mice

ONM-412 demonstrates the potential for clinical translation of the ON-BOARD™ platform

SOUTHLAKE, Texas – April 10, 2024 – OncoNano Medicine, Inc. presented a late-breaking poster detailing the preclinical efficacy and safety of muONM-412, an ON-BOARD™ nanoparticle-encapsulated murine interleukin-12 fusion protein (IL-12Fc), and in vitro characterization of ONM-412, encapsulating human IL-12Fc, at the American Association for Cancer Research (AACR) Annual Meeting 2024 in San Diego, California.

Despite its potent pleiotropic and well-established anti-cancer effects, the clinical application of IL-12 has been hindered by significant adverse toxicities. OncoNano developed ON-BOARD™, an ultra-pH sensitive nanoparticle platform, to shield payloads from systemic exposure and target solid tumors by responding to the highly acidic tumor microenvironment. Encapsulation of payloads like IL-12 by ON-BOARD™ may provide the opportunity to improve the therapeutic index of a variety of anti-cancer therapies.“

As part of the study presented at AACR, the preclinical safety and activity of muONM-412 were evaluated with the data demonstrating it significantly improved tolerability over unencapsulated IL-12Fc while showing potent antitumor efficacy in mice. Findings also reveal that ONM-412 illustrates favorable stability and pH-responsive IL-12 bioactivity in vitro,” said Tian Zhao, Ph.D., Vice President of Research and Development for OncoNano Medicine. “We believe our ON-BOARD™ ultra-pH sensitive micelle technology can transform the targeted delivery of oncology therapeutics and look forward to continuing the development of new treatments for patients with cancer.”

muONM-412 key findings:

Exhibited improved tolerability in vivo compared to unencapsulated IL-12Fc through the observation of reduced body weight loss, absence of liver toxicity and lower plasma IFNy levels.
Induced tumor immune remodeling, with increased infiltration by IFNγ+ and GzmB+ CD8 T and NK cells.
Strong dose-responsive anti-tumor efficacy shown in MC38 tumor-bearing animals.

ONM-412 key findings:

Demonstrated high encapsulation efficiency (>85%) in uniformly distributed particles (Dh<50nm) with 12-month on-going shelf-life stability.
Rapid and complete recovery of IL-12 bioactivity shown <10 minutes after acid-activation.
Confirmed pH-specific release in vitro with a >100-fold activation window between the acid-activated and intact formulations by a HEK reporter assay and an IFNγ induction assay.

OncoNano Medicine Announces Positive Preclinical Data for ON-BOARD™ IL-12 Program at SITC 2023 Annual Meeting

SOUTHLAKE, Texas – November 3, 2023 – OncoNano Medicine, Inc. today presented positive preclinical data describing the effective delivery of interleukin-12 (IL-12) with the ON-BOARD™ platform technology at the 38th Annual Meeting of the Society for Immunotherapy of Cancer (SITC).

The study findings show that encapsulation of a therapeutic IL-12 fusion protein (IL-12Fc) for tumor specific delivery and pH-dependent activation was achieved using the ON-BOARD™ polymeric micelle technology. The study also found that ON-BOARD™ significantly improved the tolerability of IL-12Fc, as compared to unencapsulated IL-12. The encapsulated IL-12Fc demonstrated potent anti-tumor efficacy and durable anti-tumor memory in the MC38 colorectal cancer model. ONM-412, the development product candidate with the IL-12 encapsulated in the ON-BOARD™ polymeric micelle system, is advancing through IND-enabling activities.“

These findings underscore the potential application of the ON-BOARD™ polymeric micelle system for the delivery of IL-12 as an anti-tumor agent,” said Tian Zhao, PhD, Vice President of Research and Development at OncoNano. “We look forward to the continued development of ONM-412 and the ONBOARD™ platform as a potential technology for the targeted delivery of therapeutics to benefit cancer patients.”

The data presented demonstrated that:

ON-BOARD™ enables murine and human IL-12Fc encapsulation with favorable stability and pH-responsive IL-12 bioactivity in vitro in a HEK reporter assay and in primary cell IFNγ induction. Compared to a protease cleavable masked IL-12, the ON-BOARD™ formulation shows rapid and complete activation over a short period of time.
ON-BOARD™ encapsulated IL-12Fc exhibited potent anti-tumor efficacy and prolonged survival in MC38 tumor-bearing animals with long-term memory effect.
ON-BOARD™ formulation demonstrated effective IL-12 signaling in the tumor as evidenced by activation of CD8 T cells and NK cells; increased levels of IFNγ were seen in the tumor but not systemic circulation.

Reduced systemic exposure was observed with ON-BOARD™ encapsulated IL-12Fc with a significant improvement in the tolerability as evidenced by reduced body weight loss, normal plasma transaminase levels for liver function, reduced splenomegaly, and reduced systemic free IL-12 levels and IL-12 related cytokines when compared to unencapsulated IL-12Fc.

OncoNano Medicine Presents Positive Final Results from Phase 2 Trial of Pegsitacianine in Podium Presentation at 2023 ASCO Annual Meeting

Study met primary endpoint of detection of residual disease following completion of standard of care surgery

Residual cancer was identified by pegsitacianine-directed fluorescence in 50% of evaluable patients

Results demonstrated acidic pH is a viable marker for use in targeted delivery

SOUTHLAKE, Texas - May 31, 2023 - OncoNano Medicine, Inc. will present positive final results from its Phase 2 study of pegsitacianine, a pH-sensitive fluorescent nanoprobe for enhanced intra-operative visualization of cancer, in a podium presentation at the American Society of Clinical Oncology (ASCO) Annual Meeting 2023. Results of the study show that acidic pH is a viable marker and can be used for tumor targeting by the company’s ON-BOARD™ micelle platform.

Pegsitacianine has been studied in more than 135 patients across multiple tumor types, including peritoneal metastatic, breast, head and neck, colorectal, esophageal, ovarian and prostate cancers. Results show that pegsitacianine is able to localize different tumor types regardless of their histology or anatomic location. The ON-BOARD platform, therefore, is able to target solid tumors, deploying its payload specifically within the acidic tumor microenvironment (TME).

“We are encouraged by this data as it demonstrates the potential of pegsitacianine to augment the visualization of cancer during an operation, which has the potential to be a significant advance in real-time surgical imaging,” said Kartik Krishnan, M.D., Ph.D., Chief Medical Officer of OncoNano Medicine. “We look forward to taking pegsitacianine to the next levels of development and continue our mission to diagnose and treat cancer with high specificity.”

The results of this Phase 2 study reveal that pegsitacianine was well tolerated and that 20 of 40 evaluable patients (50%) had pathology-confirmed disease resected, that was not resected in the planned standard of care surgery, under pegsitacianine guidance. Approximately 25% of patients experienced a pegsitacianine-related adverse event, which was a transient, selfresolving, non-anaphylactic infusion-related reaction.

“We were highly encouraged with the results observed in this Phase 2 trial and look forward to validating these findings in the upcoming Phase 3 trial,” said Patrick Wagner, M.D., lead author and Director of Complex General Surgical Oncology, Allegheny Health Network Cancer Institute. “The results demonstrate that acidic pH is a viable tumor agnostic marker and highlight pegsitacianine’s ability to target different tumor types regardless of their genotype or anatomic location.”

“This Phase 2 data brings new hope to both clinicians and patients,” said Charles M. Balch, M.D., former EVP and Chief Executive Officer of ASCO and present Chair of the Scientific Advisory Board at OncoNano Medicine. “Having demonstrated the capacity to identify tumors that were previously not clinically visible to surgeons, pegsitacianine has the potential to improve the accuracy of staging and surgical outcomes, while reducing operating time for several types of abdominal cancers. Newer versions in the pipeline have great potential to expand therapeutic targets and enable new combinations of drugs previously hindered by toxicity.”

OncoNano Presents Compelling Data for ONM-501 and a Novel Tumor Specific Delivery Technology at AACR Annual Meeting 2023

OncoNano Presents Compelling Data for ONM-501 and a Novel Tumor Specific Delivery Technology at AACR Annual Meeting 2023

- ONM-501 demonstrates enhanced tumor retention with a favorable nonclinical safety profile

- The ON-BOARD™ platform demonstrates enhanced therapeutic indices with tumor specific delivery of a bispecific antibody and a cytokine

SOUTHLAKE, Texas – April 18, 2023 – OncoNano Medicine, Inc. presented three posters at the American Association for Cancer Research (AACR) Annual Meeting 2023. The posters detail positive nonclinical data for ONM-501, the Company’s dual-activating STING (STimulator of INterferon Genes) agonist and lead therapeutic development candidate, formulated with the company’s OMNI™ polymer technology as well as positive data for encapsulated bispecific antibody and cytokine using ON-BOARD™ tumor specific delivery technology.

“STING plays a critical role in innate immune response against infection and cancer, and we continue to be pleased with the data which support further advancement of the ONM-501 program,” said Ruolan Han, Ph.D., Vice President of Nonclinical & Translational Medicine for OncoNano Medicine. “We look forward to bringing ONM-501 to the clinic this year and furthering the development of OMNI™ as we work toward our goal of delivering critical treatments to patients in need. Previous preclinical studies have shown that ONM-501 works by stabilizing the STING protein and delivering cGAMP intracellularly, where it is shielded from degradation by ectonucleotide pyrophosphatase/phosphodiesterase 1(ENPP1). Combining these observations and the immune stimulation with limited systemic toxicity observed in the nonclinical species, we believe that ONM-501 has the potential to show an improved clinical profile as compared to earlier experimental STING agonists.”

Previously, ONM-501, a dual-activating STING agonist, has demonstrated the ability to produce a burst and sustained activation of STING signaling that leads to a robust adaptive immune response through a unique polymer-STING binding mechanism which differs from earlier cyclic di-nucleotide (CDN) STING agonist programs. This novel mechanism provides potent anti-tumor efficacy as a monotherapy and in combination with anti-PD1 in multiple preclinical mouse models with both “hot” and “cold” tumor microenvironments. In vivo pharmacodynamic (PD) analysis confirmed STING activation, enhanced tumor lymphocyte infiltration, and tumor PD-L1 upregulation by ONM-501 and demonstrated the target-engagement activity of ONM-501 in multiple species. New pharmacokinetics/biodistribution data presented at the conference in tumor-bearing mice revealed that intratumorally injected ONM-501 showed high tumor retention and very low systemic exposure due to the polymeric micelle formulation, maximizing antitumor efficacy while minimizing systemic toxicity. This new data further differentiates ONM- 501 from other small molecule STING agonist programs. Safety studies in multiple species established a wide therapeutic window for ONM-501 making it a promising candidate for clinical evaluation.

Two additional posters were presented earlier in the conference, reporting encapsulation and masked delivery of Interleukin-12 (IL-12) and T cell engager bispecific antibodies using ON- BOARD™. The results demonstrate significantly improved tolerability, anti-tumor efficacy in mice and potential for clinical translation.

“Our ON-BOARD™ pH-sensitive micelle delivery platform continues to demonstrate improvement of therapeutic indices with a variety of therapeutic protein payloads including the highly potent interleukin-12 and T-cell engagers,” said Tian Zhao, Ph.D., Vice President of Research and Development for OncoNano Medicine. “We have seen challenges with other IL-12 and T-cell engager programs related to suboptimal therapeutic index, associated with toxicities related to systemic exposure. In contrast, the tumor-specific delivery of ON-BOARD™ encapsulated molecules demonstrates a much broader therapeutic window. The promising data that we presented at AACR 2023 suggest our technology may provide a solution to overcome the clinical application limitations of these highly potent protein therapeutics.”

OncoNano Medicine Presents Data from Phase 2 Pegsitacianine Study at Society of Surgical Oncology (SSO) 2023 International Congress on Surgical Cancer Care

OncoNano Medicine Presents Data from Phase 2 Pegsitacianine Study at Society of SurgicalOncology (SSO) 2023 International Congress on Surgical Cancer Care

- Pathology-confirmed residual disease was detected in 50% of patients following the completion of intended surgery under pegsitacianine-guidance

SOUTHLAKE, Texas – March 27, 2023 – OncoNano Medicine, Inc. presented data from a Phase 2 study of pegsitacianine, a pH-sensitive fluorescent nanoprobe for image-guided cancer surgery, at the Society of Surgical Oncology (SSO) 2023 International Congress on Surgical Cancer Care, occurring March 22-25 in Boston, MA. Data from the study revealed that the primary endpoint was achieved in 50% of the evaluable patients undergoing peritoneal carcinomatosis surgery.

The primary objective of this Phase 2 study was to determine if the administration of pegsitacianine (1 mg/kg) prior to surgery results in the detection of additional disease following standard of care surgical resection of peritoneal metastases. The results reveal that, under pegsitacianine guidance, 20 of 40 evaluable patients (50%) had pathology-confirmed disease resected after fluorescent visualization that was not resected in the planned standard of care surgery. In this trial, pegsitacianine was well tolerated; the only notable pegsitacianine related adverse event was a transient, self-resolving, non-anaphylactic infusion-related reaction experienced by approximately 25% of patients.

“These results show that pegsitacianine can safely be administered up to three days in advance of surgery, without any impact on the planned surgical approach. Importantly, the results of this Phase 2 trial demonstrate pegsitacianine’s potential as a new advance for real-time surgical imaging for peritoneal metastasis surgery,” said Kartik Krishnan MD, PhD, Chief Medical Officer of OncoNano Medicine. “I look forward to working alongside the U.S. Food and Drug Administration (FDA) to plan for further development and explore the most efficient opportunities to bring pegsitacianine to patients.”

The results come at the heels of the Company’s January 2023 announcement that pegsitacianine received Breakthrough Therapy Designation by the U.S. FDA as an adjunct for the visualization of metastatic disease in the peritoneal cavity in patients undergoing cytoreductive surgery.

OncoNano Medicine’s Pegsitacianine Granted Breakthrough Therapy Designation for Real-Time Surgical Imaging by the Food and Drug Administration

Southlake, TX – January 4, 2023 – OncoNano Medicine, Inc. today announced that its lead clinical development candidate, pegsitacianine, a pH-sensitive fluorescent nanoprobe for image-guided cancer surgery, has received Breakthrough Therapy Designation by the U.S. Food and Drug Administration (FDA) as an adjunct for the visualization of metastatic disease in the peritoneal cavity in patients undergoing cytoreductive surgery.

“We are thrilled to receive breakthrough therapy designation, which underscores the potential of pegsitacianine to alter the paradigm of surgical imaging in oncology,” said Kartik Krishnan, Chief Medical Officer of OncoNano. “Providing real-time feedback, pegsitacianine demonstrates the capacity to identify tumors that may otherwise go undetected.”

The FDA's Breakthrough Therapy Designation is designed to expedite development and regulatory review of medicines that aim to address a serious or life-threatening condition with showing preliminary clinical evidence demonstrating substantial improvement over existing treatments on one or more clinically significant endpoints. A Breakthrough Therapy Designation provides more intensive FDA guidance on an efficient drug development program, an organizational commitment involving senior managers, and eligibility for rolling review and priority review.

Based on the results of an ongoing Phase 2 clinical trial evaluating the safety and efficacy of pegsitacianine following standard of care cytoreductive surgery, pegsitacianine enabled surgeons to detect additional cancerous tissue at a clinically significant rate of >50%. It is estimated that each year in the United States more than 17,000 patients undergo cytoreductive surgery due to metastasis from many different tumor types, including appendiceal, colorectal or ovarian cancer.

About Pegsitacianine

Pegsitacianine is an intraoperative fluorescence imaging agent for the detection of cancerous tissue in patients undergoing removal of their solid tumor. Relying on an ultra pH-sensitive activation mechanism of OncoNano’s ON-BOARDTM platform, pegsitacianine exists in a fluorescently dark (“Off”) state at physiological pH but transitions rapidly to a fluorescently “On” state in the presence of the elevated acidic tumor microenvironment. Pegsitacianine’s unique mechanism of action provides it with the potential to function as a tumor-agnostic imaging agent compatible with most clinical cameras designed for ICG imaging across a variety of solid tumor types.

OncoNano Medicine Announces New Preclinical Data for ON-BOARD™ Platform for Delivery of Bispecific T Cell Engagers and a Therapeutic Cytokine at SITC Annual Meeting

Clinically validated pH-sensitive nanomedicine platform allows for tumor specific delivery of protein therapeutics and increased tolerabilitySOUTHLAKE, Texas – November 14, 2022 – OncoNano Medicine, Inc. today announced the presentations of positive preclinical data on the company’s ON-BOARD™ pH-activatable delivery platform at the 37th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) in Boston, Massachusetts.

The data presented at SITC 2022 demonstrated the capability of the ON-BOARD™ platform for effective encapsulation and improvement of the therapeutic index of a variety of therapeutic payloads, including bispecific T cell engagers (TCE) and a therapeutic cytokine – IL-2-Fc, using relevant animal models.

The ON-BOARD™ platform is designed to protect oncology intervention payloads systemically and release them in the acidic tumor microenvironment, minimizing systemic exposure and toxicity. OncoNano’s lead clinical candidate, pegsitacianine, currently in Phase 2 clinical trials, is formulated with ON-BOARD™, and the clinical data has validated its pH-activated tumor specificity.

In the two separate presentations, a variety of TCEs including solitomab, runimotamab and several TCEs with undisclosed targets as well as a human IL-2 fused with IgG Fc were encapsulated using the ON- BOARD™ platform. The data demonstrated that:

ON-BOARD™ successfully encapsulated TCEs across a range of different targets and structural configurations without any protein engineering involved
ON-BOARD™-encapsulated TCEs demonstrated rapid release and high pH specificity as well as pH- activated cytotoxicity against various cancer cell lines in vitro
ON-BOARD™ encapsulation of an undisclosed TCE significantly improved its tolerability in vivo compared to the unencapsulated molecule and inhibited the growth of a poorly immunogenic “cold” tumor model with in-tumor payload activation confirmed by PD markers
ON-BOARD™-encapsulated IL-2-Fc showed robust anti-tumor efficacy in both the "hot" MC38 and the "cold" B16F10 tumors and greatly suppressed systemic toxicity compared to unencapsulated IL-2-Fc

“We were excited to share the positive data on the encapsulation of a variety of bispecific T cell engagers and a therapeutic cytokine and the significant improvement of therapeutic index without complicated protein engineering,” said Tian Zhao, PhD, Vice President of Research and Development at OncoNano. “We look forward to developing this technology for clinical translation with these types of payload molecules in the near future.”

OncoNano Medicine Announces Pre-Clinical Data for Dual-Activating STING agonist at the Society for Immunotherapy of Cancer (SITC) Annual Meeting

ONM-501 shown to be promising immuno-therapeutic candidate for clinical evaluation in solid tumorsSOUTHLAKE, Texas – November 10, 2022 – OncoNano Medicine, Inc. today announced the presentation of data on its pre-clinical candidate ONM-501 at the 37th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) in Boston, Massachusetts. ONM-501, OncoNano’s lead therapeutic program in development, is a dual-activating STING (Stimulator of Interferon Genes) agonist advancing towards a first in human trial planned to be initiated in the first half of 2023.

Previously published data has demonstrated the differentiated mechanism of ONM-501 with dual “burst” and “sustained” STING activation, enhanced cytosolic delivery and tumor retention through encapsulation of an endogenous STING agonist - cGAMP with OnocoNano’s proprietary STING-activating OMNI™ polymeric micelles. These two mechanisms operate in concert to activate STING and potentiate this activation, providing potent anti-tumor efficacy as a monotherapy and in combination with anti-PD1 in multiple preclinical mouse models with both “hot” and “cold” tumor microenvironments. In vivo PD analysis confirmed STING activation, enhanced tumor lymphocyte infiltration, and tumor PD-L1 upregulation by ONM-501, and demonstrated the target-engagement activity of ONM-501 in multiple species, and high tolerability in rodents and non-human primates, making it a promising therapeutic candidate for clinical evaluation.

“The results presented here confirm many of our hypotheses regarding the potential of ONM-501 to provide a robust therapeutic index of immune activating STING activity that may be differentiated from other STING agonists. This is why we are so buoyed by the continued positive preclinical results for ONM-501, underscoring its potential as a monotherapy and in combination with anti-PD1 in multiple‘hot’ and ‘cold’ murine syngeneic tumor models,” said Kartik Krishnan, MD, PhD, Chief Medical Officer at OncoNano. “We look forward to bringing ONM-501 to the clinic in 2023 as we continue on our mission to deliver critical new treatments to patients in need.”

OncoNano Medicine Announces Positive Phase 2 Data for Pegsitacianine as an adjunct to Cytoreductive Surgery of Peritoneal Carcinomatosis

- Interim Phase 2 results presented at World Molecular Imaging Conference 2022 -

- Pegsitacianine demonstrated a >50% clinical event rate allowing the surgeons in the trial to detect residual disease following cytoreductive surgery -

SOUTHLAKE, Texas, September 29, 2022 – OncoNano Medicine, Inc. today announced positive interim clinical results from an ongoing Phase 2 study of its lead clinical development candidate, pegsitacianine, for the detection of residual disease following cytoreductive surgery (CRS). Study results were presented by Patrick Wagner, MD, Department of Surgical Oncology, Allegheny Health Network Cancer Institute, during an oral presentation at the World Molecular Imaging Congress (WMIC) in Miami, FL on September 29th. The interim results from this trial provide evidence that pegsitacianine could offer surgeons a real-time optical imaging capability that enhances their ability to detect residual cancerous tissue that would otherwise be left behind from their standard of care process for cytoreductive surgery of peritoneal metastases.

“We are encouraged by the Phase 2 study results for pegsitacianine in the detection of residual disease for both mucinous and non-mucinous metastatic nodules across multiple cancer types and look forward to further exploring the clinical utility of this novel molecular imaging agent in cancer surgery,” said Patrick Wagner, MD, one of the lead investigators on the trial.

The Phase 2 study (NCT04950166) remains open to enrollment and is designed to evaluate the ability of pegsitacianine, a micellar fluorescence agent, to detect residual malignancies following CRS, an operation to completely resect peritoneal metastases. As an adjunct to tactile and visual cues for detecting residual disease, pegsitacianine may allow surgeons a more accurate evaluation of the completeness of surgery, or potentially to augment the results by removing additional lesions. A total of 27 patients were administered pegsitacianine at a dose of 1 mg/kg, proceeded to surgery with intra- operative imaging occurring between 24- and 72-hours post-dose, and completed pathology examination of resected specimens. The data presented revealed that 15 patients (55%) have demonstrated a clinically significant detection of pathology-confirmed residual disease following the completion of intended surgery. In this ongoing study, pegsitacianine continues to be well-tolerated with no observed drug-related serious adverse events. The most common adverse event observed with the use of pegsitacianine has been infusion-related reactions that have been mild to moderate and self-resolving.

About Pegsitacianine

Pegsitacianine is an intraoperative fluorescence imaging agent under development by OncoNano Medicine for the detection of cancerous tissue in patients undergoing surgical resection. Relying on an ultra pH-sensitive activation mechanism of OncoNano’s ON-BOARD™ platform, pegsitacianine exists in a fluorescently dark “Off” state at physiological pH but transitions rapidly to a fluorescently “On” state in the presence of the elevated acidic tumor microenvironment. Pegsitacianine’s unique mechanism of action provides it with the potential for intraoperative near infrared imaging across a variety of solid tumor types. Pegsitacianine has previously been studied in Phase 1 and 2 clinical trials where breast, head and neck, colorectal, and esophageal cancers were successfully imaged following an intravenous dose of pegsitacianine.

About OncoNano Medicine

OncoNano Medicine is developing a new class of products that utilize principles of molecular cooperativity in their design to exploit pH as a biomarker to diagnose and treat cancer with high specificity. Our product candidates and interventions are designed to help patients across the continuum of cancer care and include solid tumor therapeutics, agents for real-time image guided surgery and a platform of immune-oncology therapeutics that activate and guide the body’s immune system to target cancer.

OncoNano’s lead development candidate is pegsitacianine, a novel fluorescent nanoprobe, that is currently under study in Phase 2 clinical trials as a real-time surgical imaging agent for use in multiple cancer surgeries. ONM-501, OncoNano’s second development program, is a next generation STING (STimulator of INterferon Genes) agonist that is advancing towards a first in human trial in the first half of 2023. Pegsitacianine and ONM-501 have been supported by grants received from the Cancer Prevention Research Institute of Texas. Learn more at www.OncoNano.com.
