The presentation will feature new secondary endpoint data from the first interim analysis triggered in the Phase III TIGeR-PaC study – a multi-center, open-label clinical trial. The study is evaluating RenovoGem to treat LAPC through RenovoRx’s proprietary trans-arterial micro-perfusion (TAMP) drug-delivery platform of FDA-approved gemcitabine.

The Phase III study has a primary endpoint of overall survival and several secondary endpoints, including progression-free survival (PFS) and quality of life. The study is designed to randomize 114 patients. Final analysis will be conducted after 86 events (deaths) from the stereotactic body radiation therapy (SBRT) population. The study includes two planned interim analyses, the first upon 30% (26 of 86) of total events and the second upon 60% (52 of 86) of total events.

Data from the planned first interim analysis of the Phase III TIGeR-PaC study, presented at recent American Association of Clinical Research (AACR) (Free AACR Whitepaper) 2023, demonstrated a 6-month median overall survival difference between the test arm (RenovoGem) and control arm (standard of care gemcitabine and Abraxane) along with a 65% reduction in adverse events.

"We are thrilled to announce that Dr. Michael J. Pishvaian, Principal Investigator, will present new secondary endpoint data from the interim analysis in our pivotal study at the upcoming ESMO (Free ESMO Whitepaper) GI," said Shaun Bagai, CEO, RenovoRx. "This data will notably include PFS from the Phase III study, which has historically been used as a registrational endpoint in FDA New Drug Applications both in accelerated and traditional approvals. We look forward to continued engagement with leading oncologists in the field as we advance RenovoGem and our delivery platform’s potential to benefit cancer patients."

Abstract Title: "The Phase 3 study Targeted Intra-Arterial Gemcitabine vs. Continuation of IV Gemcitabine plus Nab-Paclitaxel following Induction with Sequential IV Gemcitabine plus Nab-Paclitaxel and Radiotherapy for Locally Advanced Pancreatic Cancer (TIGeR-PaC) trend toward a survival benefit at its first interim analysis"

Abstract Number: LBA-1

Presenting Author: Michael Jon Pishvaian, M.D., Ph.D., Director of Gastrointestinal, Developmental Therapeutics and Clinical Research Programs, Associate Professor of Oncology, John Hopkins School of Public Health

Presentation Date and Time: Thursday, June 29, 2023, at 8:50 – 9:00 AM CEST

Data presented at the conference will be available to view in the Clinicians section of the RenovoRx website following the ESMO (Free ESMO Whitepaper) GI Conference.

The treatment of LAPC remains a clinical challenge with a median survival of 15-18 months from diagnosis. RenovoGem delivers gemcitabine directly to the tumor site, enhancing the therapeutic effectiveness while potentially minimizing the systemic side effects commonly associated with traditional chemotherapy intravenous administration, and potentially improving patient outcomes. RenovoGem is currently under investigation for the intra-arterial delivery of gemcitabine and has not been approved for commercial sale.

TIGeR-PaC is currently enrolling unresectable LAPC patients at several sites across the US. To learn more about the study and the participating clinical trial sites, visit View Source

About NUBEQA (darolutamide)1

NUBEQA is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription.1

On July 30, 2019, the FDA approved NUBEQA (darolutamide) based on the ARAMIS trial, a randomized, double-blind, placebo-controlled, multi-center Phase III study, which evaluated the safety and efficacy of oral NUBEQA in patients with non-metastatic castration-resistant prostate cancer (nmCRPC).

NUBEQA is also being investigated in additional studies across various stages of prostate cancer, including in the ARANOTE Phase III trial evaluating NUBEQA plus ADT versus ADT alone for metastatic hormone-sensitive prostate cancer (mHSPC), as well as in the Australian and New Zealand Urogenital and Prostate Cancer Trials Group (ANZUP) led international Phase III co-operative group DASL-HiCaP (ANZUP1801) trial evaluating NUBEQA as an adjuvant treatment for localized prostate cancer with very high risk of recurrence. Information about these trials can be found at www.clinicaltrials.gov.

Developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company, NUBEQA is indicated for the treatment of adults with nmCRPC or with mHSPC in combination with docetaxel.1 Filings in other regions are underway or planned.

INDICATIONS

NUBEQA (darolutamide) is an androgen receptor inhibitor indicated for the treatment of adult patients with:

Non-metastatic castration-resistant prostate cancer (nmCRPC)
Metastatic hormone-sensitive prostate cancer (mHSPC) in combination with docetaxel
IMPORTANT SAFETY INFORMATION

Warnings & Precautions

Ischemic Heart Disease – In a study of patients with nmCRPC (ARAMIS), ischemic heart disease occurred in 3.2% of patients receiving NUBEQA versus 2.5% receiving placebo, including Grade 3-4 events in 1.7% vs. 0.4%, respectively. Ischemic events led to death in 0.3% of patients receiving NUBEQA vs. 0.2% receiving placebo. In a study of patients with mHSPC (ARASENS), ischemic heart disease occurred in 2.9% of patients receiving NUBEQA with docetaxel vs. 2% receiving placebo with docetaxel, including Grade 3-4 events in 1.3% vs. 1.1%, respectively. Ischemic events led to death in 0.3% of patients receiving NUBEQA with docetaxel vs. 0% receiving placebo with docetaxel. Monitor for signs and symptoms of ischemic heart disease. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue NUBEQA for Grade 3-4 ischemic heart disease.

Seizure – In ARAMIS, Grade 1-2 seizure occurred in 0.2% of patients receiving NUBEQA vs. 0.2% receiving placebo. Seizure occurred 261 and 456 days after initiation of NUBEQA. In ARASENS, seizure occurred in 0.6% of patients receiving NUBEQA with docetaxel, including one Grade 3 event, vs. 0.2% receiving placebo with docetaxel. Seizure occurred 38 to 340 days after initiation of NUBEQA. It is unknown whether anti-epileptic medications will prevent seizures with NUBEQA. Advise patients of the risk of developing a seizure while receiving NUBEQA and of engaging in any activity where sudden loss of consciousness could cause harm to themselves or others. Consider discontinuation of NUBEQA in patients who develop a seizure during treatment.

Embryo-Fetal Toxicity – Safety and efficacy of NUBEQA have not been established in females. NUBEQA can cause fetal harm and loss of pregnancy. Advise males with female partners of reproductive potential to use effective contraception during treatment with NUBEQA and for 1 week after the last dose.

Adverse Reactions

In ARAMIS, serious adverse reactions occurred in 25% of patients receiving NUBEQA vs. 20% of patients receiving placebo. Serious adverse reactions in ≥1% of patients who received NUBEQA included urinary retention, pneumonia, and hematuria. Fatal adverse reactions occurred in 3.9% of patients receiving NUBEQA vs. 3.2% of patients receiving placebo. Fatal adverse reactions in patients who received NUBEQA included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%). The most common adverse reactions (>2% with a ≥2% increase over placebo), including laboratory test abnormalities, were increased AST, decreased neutrophil count, fatigue, increased bilirubin, pain in extremity, and rash. Clinically relevant adverse reactions occurring in ≥2% of patients treated with NUBEQA included ischemic heart disease and heart failure.

In ARASENS, serious adverse reactions occurred in 45% of patients receiving NUBEQA with docetaxel vs. 42% of patients receiving placebo with docetaxel. Serious adverse reactions in ≥2% of patients who received NUBEQA with docetaxel included febrile neutropenia (6%), decreased neutrophil count (2.8%), musculoskeletal pain (2.6%), and pneumonia (2.6%). Fatal adverse reactions occurred in 4% of patients receiving NUBEQA with docetaxel vs. 4% of patients receiving placebo with docetaxel. Fatal adverse reactions in patients who received NUBEQA included COVID-19/COVID-19 pneumonia (0.8%), myocardial infarction (0.3%), and sudden death (0.3%). The most common adverse reactions (≥10% with a ≥2% increase over placebo with docetaxel) were constipation, decreased appetite, rash, hemorrhage, increased weight, and hypertension. The most common laboratory test abnormalities (≥30%) were anemia, hyperglycemia, decreased lymphocyte count, decreased neutrophil count, increased AST, increased ALT, and hypocalcemia. Clinically relevant adverse reactions in <10% of patients who received NUBEQA with docetaxel included fractures, ischemic heart disease, seizures, and drug-induced liver injury.

Drug Interactions

Effect of Other Drugs on NUBEQA – Combined P-gp and strong or moderate CYP3A4 inducers decrease NUBEQA exposure, which may decrease NUBEQA activity. Avoid concomitant use.

Combined P-gp and strong CYP3A4 inhibitors increase NUBEQA exposure, which may increase the risk of NUBEQA adverse reactions. Monitor more frequently and modify NUBEQA dose as needed.

Effects of NUBEQA on Other Drugs – NUBEQA inhibits breast cancer resistance protein (BCRP) transporter. Concomitant use increases exposure (AUC) and maximal concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use where possible. If used together, monitor more frequently for adverse reactions, and consider dose reduction of the BCRP substrate.

NUBEQA inhibits OATP1B1 and OATP1B3 transporters. Concomitant use may increase plasma concentrations of OATP1B1 or OATP1B3 substrates. Monitor more frequently for adverse reactions and consider dose reduction of these substrates.

Review the Prescribing Information of drugs that are BCRP, OATP1B1, and OATP1B3 substrates when used concomitantly with NUBEQA.

For important risk and use information about NUBEQA, please see the accompanying full Prescribing Information.

About Xofigo (radium Ra 223 dichloride) Injection2

Xofigo is indicated for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases and no known visceral metastatic disease.

Important Safety Information for Xofigo (radium Ra 223 dichloride) Injection

Warnings and Precautions:

Bone Marrow Suppression: In the phase 3 ALSYMPCA trial, 2% of patients in the Xofigo arm experienced bone marrow failure or ongoing pancytopenia, compared to no patients treated with placebo. There were two deaths due to bone marrow failure. For 7 of 13 patients treated with Xofigo bone marrow failure was ongoing at the time of death. Among the 13 patients who experienced bone marrow failure, 54% required blood transfusions. Four percent (4%) of patients in the Xofigo arm and 2% in the placebo arm permanently discontinued therapy due to bone marrow suppression. In the randomized trial, deaths related to vascular hemorrhage in association with myelosuppression were observed in 1% of Xofigo-treated patients compared to 0.3% of patients treated with placebo. The incidence of infection-related deaths (2%), serious infections (10%), and febrile neutropenia (<1%) was similar for patients treated with Xofigo and placebo. Myelosuppression–notably thrombocytopenia, neutropenia, pancytopenia, and leukopenia–has been reported in patients treated with Xofigo.

Monitor patients with evidence of compromised bone marrow reserve closely and provide supportive care measures when clinically indicated. Discontinue Xofigo in patients who experience life-threatening complications despite supportive care for bone marrow failure
Hematological Evaluation: Monitor blood counts at baseline and prior to every dose of Xofigo. Prior to first administering Xofigo, the absolute neutrophil count (ANC) should be ≥1.5 × 109/L, the platelet count ≥100 × 109/L, and hemoglobin ≥10 g/dL. Prior to subsequent administrations, the ANC should be ≥1 × 109/L and the platelet count ≥50 × 109/L. Discontinue Xofigo if hematologic values do not recover within 6 to 8 weeks after the last administration despite receiving supportive care
Concomitant Use With Chemotherapy: Safety and efficacy of concomitant chemotherapy with Xofigo have not been established. Outside of a clinical trial, concomitant use of Xofigo in patients on chemotherapy is not recommended due to the potential for additive myelosuppression. If chemotherapy, other systemic radioisotopes, or hemibody external radiotherapy are administered during the treatment period, Xofigo should be discontinued
Increased Fractures and Mortality in Combination With Abiraterone Plus
Prednisone/Prednisolone: Xofigo is not recommended for use in combination with abiraterone acetate plus prednisone/prednisolone outside of clinical trials. At the primary analysis of the Phase 3 ERA-223 study that evaluated concurrent initiation of Xofigo in combination with abiraterone acetate plus prednisone/prednisolone in 806 asymptomatic or mildly symptomatic mCRPC patients, an increased incidence of fractures (28.6% vs 11.4%) and deaths (38.5% vs 35.5%) have been observed in patients who received Xofigo in combination with abiraterone acetate plus prednisone/prednisolone compared to patients who received placebo in combination with abiraterone acetate plus prednisone/prednisolone. Safety and efficacy with the combination of Xofigo and agents other than gonadotropin-releasing hormone analogues have not been established
Embryo-Fetal Toxicity: The safety and efficacy of Xofigo have not been established in females. Xofigo can cause fetal harm when administered to a pregnant female. Advise pregnant females and females of reproductive potential of the potential risk to a fetus. Advise male patients to use condoms and their female partners of reproductive potential to use effective contraception during and for 6 months after completing treatment with Xofigo
Administration and Radiation Protection: Xofigo should be received, used, and administered only by authorized persons in designated clinical settings. The administration of Xofigo is associated with potential risks to other persons from radiation or contamination from spills of bodily fluids such as urine, feces, or vomit. Therefore, radiation protection precautions must be taken in accordance with national and local regulations

Fluid Status: Dehydration occurred in 3% of patients on Xofigo and 1% of patients on placebo. Xofigo increases adverse reactions such as diarrhea, nausea, and vomiting, which may result in dehydration. Monitor patients’ oral intake and fluid status carefully and promptly treat patients who display signs or symptoms of dehydration or hypovolemia

Injection Site Reactions: Erythema, pain, and edema at the injection site were reported in 1% of patients on Xofigo

Secondary Malignant Neoplasms: Xofigo contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure may be associated with an increased risk of cancer and hereditary defects. Due to its mechanism of action and neoplastic changes, including osteosarcomas, in rats following administration of radium-223 dichloride, Xofigo may increase the risk of osteosarcoma or other secondary malignant neoplasms. However, the overall incidence of new malignancies in the randomized trial was lower on the Xofigo arm compared to placebo (<1% vs 2%; respectively), but the expected latency period for the development of secondary malignancies exceeds the duration of follow-up for patients on the trial

Subsequent Treatment With Cytotoxic Chemotherapy: In the randomized clinical trial, 16% of patients in the Xofigo group and 18% of patients in the placebo group received cytotoxic chemotherapy after completion of study treatments. Adequate safety monitoring and laboratory testing was not performed to assess how patients treated with Xofigo will tolerate subsequent cytotoxic chemotherapy

Adverse Reactions: The most common adverse reactions (≥10%) in the Xofigo arm vs the placebo arm, respectively, were nausea (36% vs 35%), diarrhea (25% vs 15%), vomiting (19% vs 14%), and peripheral edema (13% vs 10%). Grade 3 and 4 adverse events were reported in 57% of Xofigo-treated patients and 63% of placebo-treated patients. The most common hematologic laboratory abnormalities in the Xofigo arm (≥10%) vs the placebo arm, respectively, were anemia (93% vs 88%), lymphocytopenia (72% vs 53%), leukopenia (35% vs 10%), thrombocytopenia (31% vs 22%), and neutropenia (18% vs 5%)

Please see the full Prescribing Information for Xofigo (radium Ra 223 dichloride).

About Aliqopa (copanlisib) Injection4

ALIQOPA (copanlisib) is indicated for the treatment of adult patients with relapsed follicular lymphoma (FL) who have received at least two prior systemic therapies. Accelerated approval was granted for this indication based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Aliqopa is an inhibitor of phosphatidylinositol-3-kinase (PI3K) with inhibitory activity predominantly against PI3K-α and PI3K-δ isoforms expressed in malignant B cells. Aliqopa has been shown to induce tumor cell death by apoptosis and inhibition of proliferation of primary malignant B cell lines. Aliqopa inhibits several key cell-signaling pathways, including B-cell receptor signaling, CXCR12 mediated chemotaxis of malignant B cells, and NFκB signaling in lymphoma cell lines.

The clinical development program for Aliqopa also includes the Phase III study CHRONOS-4, evaluating Aliqopa in combination with standard immunochemotherapy in relapsed iNHL. More information about this trial can be found at www.clinicaltrials.gov.

IMPORTANT SAFETY INFORMATION FOR ALIQOPA (copanlisib)

Infections: Serious, including fatal, infections occurred in 19% of 317 patients treated with ALIQOPA monotherapy. The most common serious infection was pneumonia. Monitor patients for signs and symptoms of infection and withhold ALIQOPA for Grade 3 and higher infection.

Serious pneumocystis jiroveci pneumonia (PJP) infection occurred in 0.6% of 317 patients treated with ALIQOPA monotherapy. Before initiating treatment with ALIQOPA, consider PJP prophylaxis for populations at risk. Withhold ALIQOPA in patients with suspected PJP infection of any grade. If confirmed, treat infection until resolution, then resume ALIQOPA at previous dose with concomitant PJP prophylaxis.

Hyperglycemia: Grade 3 or 4 hyperglycemia (blood glucose 250 mg/dL or greater) occurred in 41% of 317 patients treated with ALIQOPA monotherapy. Serious hyperglycemic events occurred in 2.8% of patients. Treatment with ALIQOPA may result in infusion-related hyperglycemia. Blood glucose levels typically peaked 5 to 8 hours post-infusion and subsequently declined to baseline levels for a majority of patients; blood glucose levels remained elevated in 17.7% of patients one day after ALIQOPA infusion. Of 155 patients with baseline HbA1c 6.5% at the end of treatment.

Of the twenty patients with diabetes mellitus treated in CHRONOS-1, seven developed Grade 4 hyperglycemia and two discontinued treatment. Patients with diabetes mellitus should only be treated with ALIQOPA following adequate glucose control and should be monitored closely.

Achieve optimal blood glucose control before starting each ALIQOPA infusion. Withhold, reduce dose, or discontinue ALIQOPA depending on the severity and persistence of hyperglycemia.

Hypertension: Grade 3 hypertension (systolic 160 mmHg or greater or diastolic 100 mmHg or greater) occurred in 26% of 317 patients treated with ALIQOPA monotherapy. Serious hypertensive events occurred in 0.9% of 317 patients. Treatment with ALIQOPA may result in infusion-related hypertension. The mean change of systolic and diastolic BP from baseline to 2 hours post-infusion on Cycle 1 Day 1 was 16.8 mmHg and 7.8 mmHg, respectively. The mean BP started decreasing approximately 2 hours post-infusion; BP remained elevated for 6 to 8 hours after the start of the ALIQOPA infusion. Optimal BP control should be achieved before starting each ALIQOPA infusion. Monitor BP pre- and post-infusion. Withhold, reduce dose, or discontinue ALIQOPA depending on the severity and persistence of hypertension.

Non-infectious Pneumonitis: Non-infectious pneumonitis occurred in 5% of 317 patients treated with ALIQOPA monotherapy. Withhold ALIQOPA and conduct a diagnostic examination of a patient who is experiencing pulmonary symptoms such as cough, dyspnea, hypoxia, or interstitial infiltrates on radiologic exam. Patients with pneumonitis thought to be caused by ALIQOPA have been managed by withholding ALIQOPA and administration of systemic corticosteroids. Withhold, reduce dose, or discontinue ALIQOPA depending on the severity and persistence of non-infectious pneumonitis.

Neutropenia: Grade 3 or 4 neutropenia occurred in 24% of 317 patients treated with ALIQOPA monotherapy. Serious neutropenic events occurred in 1.3%. Monitor blood counts at least weekly during treatment with ALIQOPA. Withhold, reduce dose, or discontinue ALIQOPA depending on the severity and persistence of neutropenia.

Severe Cutaneous Reaction: Grade 3 and 4 cutaneous reactions occurred in 2.8% and 0.6% of 317 patients treated with ALIQOPA monotherapy respectively. Serious cutaneous reaction events were reported in 0.9%. The reported events included dermatitis exfoliative, exfoliative rash, pruritus, and rash (including maculo-papular rash). Withhold, reduce dose, or discontinue ALIQOPA depending on the severity and persistence of severe cutaneous reactions.

Embryo-Fetal Toxicity: Based on findings in animals and its mechanism of action, ALIQOPA can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of copanlisib to pregnant rats during organogenesis caused embryo-fetal death and fetal abnormalities in rats at maternal doses as low as 0.75 mg/kg/day (4.5 mg/m2 /day body surface area) corresponding to approximately 12% the recommended dose for patients. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment and for one month after the last dose.

Adverse Drug Reactions: Serious adverse reactions were reported in 44 (26%) patients. The most frequent serious adverse reactions that occurred were pneumonia (8%), pneumonitis (5%) and hyperglycemia (5%). Adverse reactions resulted in dose reduction in 36 (21%) and discontinuation in 27 (16%) patients. The most frequently observed adverse drug reactions (≥20%) in ALIQOPA-treated patients were: hyperglycemia (54%), leukopenia (36%), diarrhea (36%), decreased general strength and energy (36%), hypertension (35%), neutropenia (32%), nausea (26%), thrombocytopenia (22%), and lower respiratory tract infections (21%).

Drug Interactions: Avoid concomitant use with strong CYP3A inducers. Reduce the ALIQOPA dose to 45 mg when concomitantly administered with strong CYP3A inhibitors.

Lactation: Advise women not to breastfeed. Advise a lactating woman not to breastfeed during treatment with ALIQOPA and for one month after the last dose.

Pionyr Immunotherapeutics’ Phase 1a Study of TREM1-targeting Antibody PY159 for the Treatment of Solid Tumors Featured at ASCO 2023

On May 25, 2023 Pionyr Immunotherapeutics, Inc., a company developing first-in-class Myeloid Tuning antibody therapeutics that enhance the body’s antitumor immunity by altering, or "tuning," immune cells within the tumor microenvironment, reported that PY159, a monoclonal antibody targeting TREM1 (triggering receptor expressed on macrophages 1), was well-tolerated with signals of durable therapeutic activity in a Phase 1a dose-escalation study as a single agent and in combination with pembrolizumab (Press release, Pionyr Immunotherapeutics, MAY 25, 2023, View Source [SID1234632119]). In 37 evaluable patients, two demonstrated partial responses and nine showed stable disease. A recommended dose of 3 mg/kg of PY159 has been determined, and seven expansion cohorts in prespecified indications are currently enrolling in the Phase 1b portion of the study. The study will be featured in a poster discussion session at the 2023 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, held June 2-6 in Chicago and virtually.

"PY159 is designed to activate the signaling of TREM1, which reprograms tumor-associated myeloid cells to stimulate anti-tumor immunity," said Leonard Reyno, President, R&D and Chief Medical Officer of Pionyr Immunotherapeutics. "The radiographic response data provide encouraging signals of efficacy, which is exciting given the novel Myeloid Tuning approach we are pursuing. This response combined with acceptable safety and tolerability both as a monotherapy and in combination with checkpoint inhibitor demonstrate the potential of this approach for treating solid tumors."

Safety and Tolerability as a Monotherapy and in Combination with Pembrolizumab Support Additional Clinical Studies

The Phase 1a dose-escalation study of PY159 was a non-randomized, open-label study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of PY159 as a single agent and in combination with checkpoint inhibitor pembrolizumab in 37 subjects with advanced solid tumors. Dosing was intravenous and administered once every three weeks. Seven predefined dose levels of PY159 were delivered as a single agent, and four dose levels of PY159 were delivered in combination with pembrolizumab. No clinically relevant neutropenia was observed. The most common treatment-related adverse events were infusion-related reactions, arthralgia, fatigue, myalgia, and stomatitis, which were primarily Grade 1 or 2; however, one subject experienced a dose-limiting toxicity of asymptomatic Grade 3 transaminitis.

Early Radiographic Response Data Support Additional Clinical Studies

Out of the 37 evaluable subjects, the best radiographic response for clinical study participants was stable disease in nine subjects (25.7%: duration range 12-96+ weeks) and partial response in two subjects (5.7%, duration range 24-42 weeks). The two partial responses were in pancreatic and ovarian cancer. Dose expansion cohorts are currently enrolling in ovarian, breast (triple negative and HR+HER2-), colorectal, pancreatic, non-small cell lung, and head and neck cancers.

Poster Presentation at ASCO (Free ASCO Whitepaper) 2023

The poster titled, "A Phase 1a Dose Escalation Study of PY159, a Monoclonal Antibody Targeting TREM1, Triggering Receptor Expressed on Myeloid Cells 1," will be featured in a poster discussion session at the ASCO (Free ASCO Whitepaper) 2023 Annual Meeting at 3-4:30 pm CDT on June 3, 2023. The abstract is currently available on the ASCO (Free ASCO Whitepaper) 2023 website, and the poster will be available on the Pionyr company website here after the completion of the ASCO (Free ASCO Whitepaper) poster session.

About Myeloid Tuning

Pionyr has developed a therapeutic platform called Myeloid Tuning, a process that rebalances the tumor microenvironment (TME) to promote anti-tumor immunity. Myeloid cells are a type of immune cell and are part of a family of cell types that play an important role in both the activation and suppression of the immune response to cancer.

One such critical type of myeloid cell, tumor-associated macrophages (TAM), are a key component of the TME. TAMs are generally categorized into two functionally contrasting subtypes called M1-like and M2-like macrophages: M1-like typically exerts anti-tumor functions, including directly mediating antibody-dependent cell-mediated cytotoxicity (ADCC) to kill tumor cells; M2-like macrophages can promote the occurrence and metastasis of tumor cells, inhibit T cell-mediated anti-tumor immune response, promote tumor angiogenesis and lead to tumor progression.

Myeloid Tuning effectively describes the mechanism of introducing agents that shift the balance of inhibitory myeloid cells – including M2-like TAMs – towards more inflammatory M1-like TAMs to promote anti-tumor immune responses in the TME and destroy solid tumors.

About PY159

PY159 is an afucosylated humanized IgG1 monoclonal antibody that specifically binds human Triggering Receptor Expressed on Myeloid Cells 1 (TREM1). In preclinical studies, PY159 effectively induces signaling through the TREM1–DAP12 complex, leading to downstream phosphorylation, and an increase in production of cytokines and chemokines and the upregulation of costimulatory and activation markers. PY159 repolarizes intratumoral immunosuppressive myeloid cells, including M2-like anti-inflammatory tumor associated macrophages (TAMs), monocytes (monocytic myeloid derived suppressor cells, mMDSCs), and neutrophils (TANs) within the tumor microenvironment to become proinflammatory to promote anti-tumor immunity.
