Data to be highlighted include an oral presentation detailing results from the Phase 3 BRUIN CLL-322 study of Jaypirca (pirtobrutinib), a non-covalent Bruton tyrosine kinase (BTK) inhibitor, as part of a time-limited regimen for patients with previously treated chronic lymphocytic leukemia (CLL). Lilly is strengthening its hematology portfolio through the recently announced proposed acquisitions of Ajax Therapeutics, Inc.* and Kelonia Therapeutics, Inc.*, each of which will present data at the meeting. Ajax Therapeutics will present the first clinical data from the Phase 1 AJX-101 study evaluating AJ1-11095, an investigational first-in-class type II JAK2 inhibitor, in patients with myelofibrosis who have been failed by a type I JAK2 inhibitor. Kelonia Therapeutics will present additional correlative data from the Phase 1 inMMyCAR study of an investigational anti-B-cell maturation antigen (BCMA) targeted in vivo CAR-T therapy in patients with relapsed and refractory multiple myeloma. Both proposed acquisitions by Lilly are pending transaction closes.

"These data at EHA (Free EHA Whitepaper) represent a significant moment for Lilly’s hematology ambitions," said Jacob Van Naarden, executive vice president and president of Lilly Oncology. "The Phase 3 BRUIN CLL-322 results address an important question for patients with relapsed or refractory CLL, demonstrating that time-limited pirtobrutinib can meaningfully improve outcomes when added to an already effective venetoclax-based regimen. Alongside the first clinical data from Ajax and additional results from Kelonia in support of the recently presented data at ASCO (Free ASCO Whitepaper), these results reflect our relentless commitment to pursue meaningful advancements for people living with blood disorders."

Presentation Highlights:

Lilly:

In a late-breaking oral presentation, Lilly will share results from the Phase 3 BRUIN CLL-322 study, evaluating a time-limited regimen of pirtobrutinib plus venetoclax and rituximab versus venetoclax and rituximab in patients with relapsed or refractory CLL/SLL. BRUIN CLL-322 is the first Phase 3 readout in CLL to outperform a venetoclax-containing control arm in any CLL setting. Lilly previously announced that the study met its primary endpoint, demonstrating that the addition of pirtobrutinib to venetoclax plus rituximab led to a statistically significant and clinically meaningful improvement in progression-free survival (PFS). These results were also selected to be featured in the EHA (Free EHA Whitepaper) press program.
Ajax Therapeutics:

In an oral presentation, Ajax will share the first clinical results from the Phase 1 AJX-101 clinical trial, evaluating AJ1-11095, an investigational first-in-class type II JAK2 inhibitor, in patients with myelofibrosis who have been failed by a type I JAK2 inhibitor. These data will also be featured in the EHA (Free EHA Whitepaper) press program.
Kelonia Therapeutics:

In an oral presentation, Kelonia will share additional correlative data from the Phase 1 inMMyCAR dose-escalation study, evaluating KLN-1010 in relapsed or refractory multiple myeloma.

About Jaypirca (pirtobrutinib)
Jaypirca (pirtobrutinib) (pronounced jay-pihr-kaa) is a highly selective (300 times more selective for BTK versus 98% of other kinases tested in preclinical studies), non-covalent inhibitor of the enzyme BTK.1 BTK is a validated molecular target found across numerous B-cell leukemias and lymphomas including mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL).2,3 Jaypirca is a U.S. FDA-approved oral prescription medicine, 100 mg or 50 mg tablets taken as a once-daily 200 mg dose with or without food until disease progression or unacceptable toxicity.

INDICATIONS FOR JAYPIRCA (pirtobrutinib)
Jaypirca is indicated for the treatment of

Adult patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) who have previously been treated with a covalent BTK inhibitor.
Adult patients with relapsed or refractory (R/R) mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a BTK inhibitor. This indication is approved under accelerated approval based on response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
IMPORTANT SAFETY INFORMATION FOR JAYPIRCA (pirtobrutinib)

Infections: Fatal and serious infections (including bacterial, viral, fungal) and opportunistic infections occurred in Jaypirca-treated patients. Across clinical trials, Grade ≥3 infections occurred (25%), most commonly pneumonia (20%); fatal infections (5%), sepsis (6%), and febrile neutropenia (3.8%) occurred. In patients with CLL/SLL, Grade ≥3 infections occurred (32%), with fatal infections occurring in 8%. Opportunistic infections included Pneumocystis jirovecii pneumonia and fungal infection. Consider prophylaxis, including vaccinations and antimicrobial prophylaxis, in patients at increased risk for infection, including opportunistic infections. Monitor for signs and symptoms, evaluate, and treat. Based on severity, reduce dose, temporarily withhold, or permanently discontinue Jaypirca.

Hemorrhage: Fatal and serious hemorrhage has occurred with Jaypirca. Across clinical trials, major hemorrhage (Grade ≥3 bleeding or any central nervous system bleeding) occurred (2.6%), including gastrointestinal hemorrhage; fatal hemorrhage occurred (0.3%). Bleeding of any grade, excluding bruising and petechiae, occurred (16%). Major hemorrhage occurred when taking Jaypirca with (2.0%) and without (0.6%) antithrombotic agents. Consider risks/benefits of co-administering antithrombotic agents with Jaypirca. Monitor for signs of bleeding. Based on severity, reduce dose, temporarily withhold, or permanently discontinue Jaypirca. Consider withholding Jaypirca 3-7 days pre- and post-surgery based on surgery type and bleeding risk.

Cytopenias: Jaypirca can cause cytopenias, including neutropenia, thrombocytopenia, and anemia. Across clinical trials, Grade 3 or 4 cytopenias, including decreased neutrophils (27%), decreased platelets (13%), and decreased hemoglobin (11%), developed. Grade 4 decreased neutrophils (15%) and Grade 4 decreased platelets (6%) developed. Monitor complete blood counts regularly. Based on severity, reduce dose, temporarily withhold, or permanently discontinue Jaypirca.

Cardiac Arrhythmias: Cardiac arrhythmias occurred in patients taking Jaypirca. Across clinical trials, atrial fibrillation or flutter were reported in 3.4% of Jaypirca treated patients, with Grade 3 or 4 atrial fibrillation or flutter in 1.6%. Other serious cardiac arrhythmias such as supraventricular tachycardia and cardiac arrest occurred (0.4%). Cardiac risk factors such as hypertension or previous arrhythmias may increase risk. Monitor and manage signs and symptoms of arrhythmias (e.g., palpitations, dizziness, syncope, dyspnea). Based on severity, reduce dose, temporarily withhold, or permanently discontinue Jaypirca.

Second Primary Malignancies: Across clinical trials, second primary malignancies, including non-skin carcinomas, developed in 9% of Jaypirca-treated patients, most frequently non-melanoma skin cancer (4.4%). Other second primary malignancies included solid tumors (including genitourinary and breast cancers) and melanoma. Advise patients to use sun protection and monitor for development of second primary malignancies.

Hepatotoxicity, Including Drug-Induced Liver Injury (DILI): Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of DILI, has occurred in patients treated with BTK inhibitors, including Jaypirca. Evaluate bilirubin and transaminases at baseline and throughout Jaypirca treatment. For patients who develop abnormal liver tests after Jaypirca, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold Jaypirca. If DILI is confirmed, discontinue Jaypirca.

Embryo-Fetal Toxicity: Jaypirca can cause fetal harm. Administration of pirtobrutinib to pregnant rats caused embryo-fetal toxicity, including embryo-fetal mortality and malformations at maternal exposures (AUC) approximately 3-times the recommended 200 mg/day dose. Advise pregnant women of fetal risk and females of reproductive potential to use effective contraception during treatment and for one week after last dose.

Serious ARs in ≥3% of patients in the randomized controlled trial were pneumonia (21%), COVID-19 (5%), sepsis (3.4%). Fatal ARs within 28-30 days of last Jaypirca dose occurred in 8-11% of patients, most commonly due to infections (7-10%), including sepsis (5%), COVID-19 (2.7-5%), and pneumonia (3.4%).

Dose Modifications and Discontinuations Due to ARs: Dose reductions in 3.6-10%, treatment interruption in 42-51%, and permanent discontinuation of Jaypirca in 9-17% of patients. Permanent discontinuation in >1% of patients included second primary malignancy, pneumonia, COVID-19, neutropenia, sepsis, anemia, and cardiac arrhythmias.

Most common ARs and Select Laboratory Abnormalities (≥20%) (all Grades %, Grade 3-4 %)–in a randomized controlled trial: neutrophil count decreased (54; 26), hemoglobin decreased (45; 10), platelet count decreased (37; 17), pneumonia (28; 16), ALT increased (25; 1.8), creatinine increased (25; -), calcium decreased (23; 0.9), sodium decreased (22; 0.9), bilirubin increased (21; 0.9), upper respiratory tract infections (21; 0.9); in a single-arm trial: neutrophil count decreased (63; 45), hemoglobin decreased (48; 19), calcium decreased (40; 2.8), fatigue (36; 2.7), bruising (36; -), cough (33; -), musculoskeletal pain (32; 0.9), platelet count decreased (30; 15), sodium decreased (30; -), COVID-19 (28; 7), pneumonia (27; 16), diarrhea (26; -), abdominal pain (25; 2.7), lymphocyte count decreased (23; 8), ALT increased (23; 2.8), AST increased (23; 1.9), creatinine increased (23; -), dyspnea (22; 2.7), hemorrhage (22; 2.7), lipase increased (21; 7), alkaline phosphatase increased (21; -), edema (21; -), nausea (21; -), pyrexia (20; 2.7), headache (20; 0.9). Grade 4 laboratory abnormalities in >5% of patients included neutrophils decreased (23).

Drug Interactions

Strong CYP3A Inhibitors: Concomitant use increased pirtobrutinib systemic exposure, which may increase risk of Jaypirca ARs. Avoid using strong CYP3A inhibitors with Jaypirca. If concomitant use is unavoidable, reduce Jaypirca dose according to approved labeling.

Strong or Moderate CYP3A Inducers: Concomitant use decreased pirtobrutinib systemic exposure, which may reduce Jaypirca efficacy. Avoid using Jaypirca with strong or moderate CYP3A inducers. If concomitant use with moderate CYP3A inducers is unavoidable, increase Jaypirca dose according to approved labeling.

Sensitive CYP2C8, CYP2C19, CYP3A, P-gp, or BCRP Substrates: Use with Jaypirca increased their plasma concentrations, which may increase risk of ARs related to these substrates for drugs sensitive to minimal concentration changes. Follow recommendations for these sensitive substrates in their approved labeling.

Use in Specific Populations

Pregnancy and Lactation: Due to potential for Jaypirca to cause fetal harm, verify pregnancy status in females of reproductive potential prior to starting Jaypirca. Presence of pirtobrutinib in human milk is unknown. Advise women to use effective contraception and to not breastfeed while taking Jaypirca and for one week after last dose.

Geriatric Use: In the pooled safety population of patients with hematologic malignancies, patients aged ≥65 years experienced higher rates of Grade ≥3 ARs and serious ARs compared to patients <65 years of age.

Renal Impairment: Because severe renal impairment increases pirtobrutinib exposure, reduce Jaypirca dose in these patients according to approved labeling.

The study results will be presented in a late-breaking abstract ("LBA") oral session at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) ("ASCO") Annual Meeting today, Tuesday, June 2, 2026, 12:09 p.m. CDT.

The PAM pathway is a key oncogenic driver of HR+/HER2- breast cancer that requires inhibition of multiple molecular components to comprehensively blockade excessive PAM signaling in tumors with or without a PAM variant. Gedatolisib is the first multitarget PAM inhibitor to demonstrate superior efficacy relative to a single-target inhibitor of this pathway. In the PIK3CA MT cohort of the Phase 3 VIKTORIA-1 trial, the gedatolisib-triplet demonstrated a statistically significant and clinically meaningful improvement in median PFS among patients, increasing the likelihood of survival without disease progression or death by two times compared to alpelisib plus fulvestrant (based on a hazard ratio [HR] of 0.50; 95% CI: 0.37-0.68; p<0.0001). The median PFS, as assessed by blinded independent central review ("BICR"), was nearly two-times longer, 11.1 months versus 5.6 months, compared to alpelisib plus fulvestrant. The ORR of the gedatolisib-triplet was 48.9% compared to 26.0% with alpelisib plus fulvestrant and the median DOR for the gedatolisib triplet was 15.7 months compared to 7.5 months for alpelisib plus fulvestrant.

For the gedatolisib-doublet, the median PFS was more than two-times longer, 11.3 months versus 5.6 months, compared to alpelisib plus fulvestrant (HR=0.51; 95% CI: 0.33-0.79; descriptive p=0.0013). The ORR of the gedatolisib-doublet was 35.7% and the median DOR was 24.2 months.

The topline gedatolisib-triplet efficacy data from the VIKTORIA-1 PIK3CA MT cohort established several new milestones in the history of drug development for HR+/HER2- ABC:

● First Phase 3 trial to demonstrate superiority of one PAM inhibitor versus another.

● The median PFS of 11.1 months for the gedatolisib-triplet is the highest reported by any Phase 3 trial for patients with HR+/HER2- ABC receiving a regimen including endocrine therapy as second-line treatment.

● The objective response rate of 48.9% for the gedatolisib-triplet is the highest reported by any Phase 3 clinical trial for a regimen including endocrine therapy in second-line HR+/HER2- ABC.

"Therapies that target only PI3Kα or AKT typically offer modest benefit for patients with PIK3CA mutant HR+/HER2- advanced breast cancer whose disease has progressed while on or after treatment with a CDK4/6 inhibitor," said Sara Hurvitz, MD, Senior Vice President, Clinical Research Division, Fred Hutchinson Cancer Center, Smith Family Endowed Chair in Women’s Health and Professor and Head, Division of Hematology and Oncology, University of Washington, Department of Medicine and co-principal investigator for the trial. "By comprehensively blocking the PI3K/AKT/mTOR, or PAM, pathway, gedatolisib combined with fulvestrant, with or without palbociclib, showed it can offer these patients two times the likelihood of survival without disease progression or death relative to a single-target inhibitor of the PAM pathway. With these results, the gedatolisib regimens, if approved, represent a new potential standard of care for patients with HR+, HER2-negative, PIK3CA mutant advanced breast cancer whose disease progressed on or after treatment with a CDK4/6 inhibitor."

The gedatolisib-triplet and -doublet were generally well tolerated in the trial with mostly low-grade treatment-related adverse events ("TRAEs"). The most common Grade 3+ TRAEs for the gedatolisib-triplet, the gedatolisib-doublet, and alpelisib plus fulvestrant groups included neutropenia (58.8%, 0%, and 0.7% of patients, respectively); stomatitis (16.3%, 5.8%, and 5.3% of patients, respectively); rash (6.5%, 5.8%, and 15.1% of patients, respectively); and hyperglycemia (2.6%, 0%, and 14.5% of patients, respectively). TRAEs led to the discontinuation of study treatment in 2.6% of patients in the gedatolisib-triplet group, 3.8% in the gedatolisib-doublet group, and 7.1% in the alpelisib plus fulvestrant group. 1One Grade 5 TRAE in the gedatolisib-triplet group, which was related to palbociclib, was reported, no Grade 5 TRAE’s were reported in the gedatolisib-doublet group, and two Grade 5 TRAE’s were reported in the alpelisib plus fulvestrant group.

"Both gedatolisib regimens were well-tolerated with few VIKTORIA-1 patients discontinuing treatment due to an adverse event," said Igor Gorbatchevsky, MD, Chief Medical Officer of Celcuity. "These safety results compare very favorably to those from the patient group treated with alpelisib and fulvestrant, which we believe reflects the benefit of gedatolisib’s multi-target mechanism of action, pharmacokinetic profile, and intravenous administration."

Overall survival, a key secondary endpoint in VIKTORIA-1, while immature at the time of the analysis, showed promising trends for both the gedatolisib-triplet and -doublet.

Celcuity intends to submit these data to the U.S. Food and Drug Administration ("FDA") as a supplemental New Drug Application ("sNDA") and to submit VIKTORIA-1 data to other regulatory authorities following the sNDA submission.

"It is rare in oncology for a targeted therapy to offer both improved efficacy and better safety results relative to another drug in its class," said Brian Sullivan, CEO and co-founder of Celcuity. "This second positive Phase 3 data readout further underscores the broad potential of multi-target PAM inhibition and increases our excitement about our two Phase 3 trials in the first-line setting for HR+/HER2- advanced breast cancer. We are on track to launch gedatolisib commercially, in anticipation of its potential FDA approval in the third quarter of 2026, and we look forward to the possibility of bringing this important therapy to physicians treating patients with advanced breast cancer."

The FDA has granted Priority Review of Celcuity’s New Drug Application ("NDA") for gedatolisib in patients with HR+/HER2-/PIK3CA wild-type ("WT") ABC and assigned a Prescription Drug User Fee Act ("PDUFA") goal date of July 17, 2026.

About HR+/HER2- Breast Cancer

Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed globally in 2022.1 While survival rates are high for those diagnosed with early breast cancer, only approximately 30% of patients who are diagnosed with or who progress to metastatic disease are expected to live five years after their diagnosis.2 HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers.2

Three interconnected signaling pathways, estrogen, cyclin D1-CDK4/6, and the PAM pathway , are primary oncogenic drivers of HR+/HER2- ABC.3 Therapies inhibiting these pathways are approved and used in various combinations for ABC. Currently approved inhibitors of the PAM pathway for breast cancer target a single PAM pathway component, such as PI3Kα, AKT, or mTORC1.4,5,6,7 However, resistance to CDK4/6 inhibitors and current endocrine therapies develops in many patients with advanced disease.8 Optimizing the inhibition of the PAM pathway is an active area of focus for breast cancer research.

About the VIKTORIA-1 Phase 3 Trial

VIKTORIA-1 is a Phase 3 open-label, randomized clinical trial to evaluate the efficacy and safety of gedatolisib in combination with fulvestrant, with or without palbociclib, in adults with HR+/HER2- ABC whose disease progressed on or after prior CDK4/6 therapy in combination with an aromatase inhibitor. The trial enrolled 701 subjects regardless of PIK3CA status while enabling separate evaluation of subjects according to their PIK3CA status. Detailed results from the PIK3CA WT cohort of VIKTORIA-1 have been previously reported. For the PIK3CA MT cohort, 350 subjects who met eligibility criteria and had confirmed PIK3CA mutations were randomly assigned (3:3:1) to receive a regimen of either the gedatolisib-triplet, alpelisib and fulvestrant, or the gedatolisib-doublet.

About Gedatolisib

Gedatolisib is an investigational, multi-target PAM inhibitor that potently targets all four class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway.9,10,11 As a multi-target PAM inhibitor, gedatolisib’s mechanism of action is highly differentiated from currently approved single-target inhibitors of the PAM pathway.11 Inhibition of only a single PAM component gives tumors an escape mechanism through cross-activation of the uninhibited targets. Gedatolisib’s comprehensive PAM pathway inhibition ensures full suppression of PAM activity by eliminating adaptive resistance cross-activation that occurs with single-target inhibitors. Unlike single-target inhibitors of the PAM pathway, gedatolisib has demonstrated equal potency and comparable cytotoxicity in PIK3CA-mutant and -wild-type breast tumor cells in nonclinical studies and early clinical data.

Recent presentations and publications emerging from the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting have reinforced the importance of targeting RAS-driven malignancies, particularly pancreatic ductal adenocarcinoma (PDAC), where KRAS mutations and downstream RAS activation are central drivers of tumor growth and therapeutic resistance. Can-Fite previously reported preclinical findings demonstrating that namodenoson exerts potent anti-tumor activity in pancreatic cancer through a multi-pathway mechanism involving deregulation of the RAS, Wnt/β-catenin, and NF-κB signaling pathways, leading to apoptosis and marked inhibition of tumor growth.

The Company also reported encouraging clinical observations from its Phase 2a study of namodenoson as a monotherapy in pancreatic cancer. Enrollment has been completed and several patients have demonstrated prolonged disease control, including one patient who has remained on therapy and follow-up for approximately 16 months.

"Growing clinical validation of RAS inhibition in pancreatic cancer supports the relevance of the pathway that namodenoson was shown to modulate in our preclinical work," said Pnina Fishman, Chairperson and CSO of Can-Fite BioPharma. "Importantly, namodenoson offers a differentiated approach through simultaneous targeting of RAS, Wnt/β-catenin and NF-κB signaling pathways together with a favorable safety profile observed across clinical programs. The durable observation in our pancreatic study further encourages continued development of namodenoson in this highly aggressive malignancy."

Pancreatic cancer remains among the most lethal malignancies, with limited treatment options and poor long-term survival. Approximately 90% of pancreatic cancers are associated with KRAS pathway activation, highlighting the importance of therapies capable of modulating this signaling network.

About Namodenoson

Namodenoson is a highly selective A3 adenosine receptor (A3AR) agonist, which has shown a compelling safety profile and demonstrated anti-tumor activity in preclinical pancreatic cancer models. The drug is also being evaluated in clinical trials for advanced liver cancer.

Namodenoson has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for the treatment of pancreatic cancer.

Iza-bren has now shown clinical benefit in three Phase 3 trials, underscoring its broad therapeutic potential. PANKU-Breast02 is the first Phase 3 study of a bispecific ADC to report positive results for dual primary endpoints of both PFS and OS in TNBC, while PANKU-Esophagus01 marks the first Phase 3 trial of a bispecific ADC in esophageal cancer to report positive dual primary endpoints of both PFS and OS. Iza-bren previously demonstrated positive phase 3 results in recurrent or metastatic nasopharyngeal carcinoma (NPC), presented at ESMO (Free ESMO Whitepaper) 2025.

"As a potentially first-in-class EGFRxHER3 bispecific antibody-drug conjugate, iza-bren has now shown significant clinical benefit in three Phase 3 trials in different cancer types, and the strength of these data presented at ASCO (Free ASCO Whitepaper) further reinforce the value iza-bren can deliver over current standards of care," said Dr. Yi Zhu, chief executive officer of Biokin. "We are proud to share these results as we continue to evaluate iza-bren to unlock the full potential of this dual mechanism of action to improve outcomes for patients in need."

"Iza-bren can address a critical gap for patients who develop resistance or experience disease progression after prior therapies and may also hold potential in earlier lines of therapy," said Cristian Massacesi, MD, executive vice president, chief medical officer and head of development, Bristol Myers Squibb. "We have a broad development program for iza-bren and believe it has the potential to be a cornerstone treatment in a number of different cancers and easily combined with other therapies."

Results from the Interim Analysis of PANKU-Breast02 (BL-B01D1-307)

The Phase 3 PANKU-Breast02 trial evaluated iza-bren in patients with unresectable locally advanced or metastatic TNBC whose disease progressed following 1-2 prior lines of systemic therapy for advanced disease, including prior taxane therapy. Patients were randomized 1:1 to receive iza-bren (n=207) or physician’s choice of chemotherapy (TPC; n=211), which included eribulin, capecitabine, gemcitabine, or vinorelbine. The study met both dual primary endpoints at a prespecified interim analysis, demonstrating a statistically significant and clinically meaningful improvement in OS and BICR-assessed PFS with iza-bren compared to TPC.

With a median follow-up of 11 months, median OS was 15.9 months with iza-bren vs. 12.5 months with TPC (HR: 0.60; 95% CI: 0.42-0.85; p=0.0019)
Median PFS by Blinded Independent Central Review (BICR) was 8.5 months with iza-bren vs. 3.1 months with TPC (HR: 0.29; 95% CI: 0.22-0.38; p<0.0001)
The confirmed objective response rate (ORR) assessed by BICR was 51.7% with iza-bren compared to 20.5% with TPC (odds ratio, 4.3; 95% CI: 2.8-6.7)
"While there have been significant advancements in breast cancer treatment, advanced triple-negative breast cancer has remained a challenge, with patients facing poor outcomes," said Dr. Jiong Wu, Fudan University Shanghai Cancer Center. "These results highlight the potential for iza-bren to be a new standard of care as the first bispecific ADC to show improved progression-free and overall survival in a Phase 3 study in this patient population."

Iza-bren showed a manageable safety profile in this heavily pre-treated patient population, with no new safety signals observed. Grade >3 treatment-emergent adverse events (TEAEs) were predominantly hematologic toxicities and consistent with the known safety profile of iza-bren. Any grade interstitial lung disease (ILD) was reported in 3 (1.4%; 1 case of grade 1 and 2 cases of grade 2) patients treated with iza-bren and 0 patients treated with TPC. Treatment discontinuation due to TEAEs occurred in 4 (1.9%) patients treated with iza-bren and 1 (0.5%) patients treated with TPC.

Results from the Interim Analysis of PANKU-Esophagus01 (BL-B01D1-305)

The Phase 3 PANKU-Esophagus01 trial evaluated iza-bren in patients with recurrent or metastatic esophageal squamous cell carcinoma who had progressed after first-line treatment with a PD-1/PD-L1 inhibitor plus platinum-based chemotherapy (n=249) compared to chemotherapy of physician’s choice (n=248). Results from the interim analysis show iza-bren demonstrated a statistically significant and clinically meaningful improvement in the dual primary endpoints of OS and BICR-assessed PFS.

Median OS was 9.8 months with iza-bren vs. 7.2 months with chemotherapy (HR: 0.64; 95% CI: 0.49-0.83; p=0.0004).
Median PFS by BICR was 4.2 months with iza-bren vs. 2.0 months with chemotherapy (HR:0.50; 95% CI: 0.40-0.63; p<0.0001).
Iza-bren also demonstrated an improvement in responses with an ORR by BICR of 35.3% compared to 13.1% with chemotherapy.
"Metastatic esophageal squamous cell carcinoma is an aggressive disease with a five-year survival rate of less than 5%, and there remains a critical unmet need for treatment options after first-line immunotherapy and chemotherapy," said Dr. Lin Shen, Peking University Cancer Hospital and Institute. "As the first Phase 3 clinical trial of a novel EGFRxHER3 bispecific antibody-drug conjugate to report positive data in this patient population, these results show the potential for iza-bren to set a new benchmark in significantly extending survival for patients with recurrent or metastatic esophageal squamous cell carcinoma."

Iza-bren also showed a manageable safety profile in this patient population. Grade >3 treatment-related adverse events (TRAEs), which were predominantly hematologic toxicities, occurred in 85.1% of patients treated with iza-bren and 60.2% of patients who received chemotherapy. TRAEs that led to treatment discontinuation occurred in 2% of patients treated with iza-bren and 3.3% treated with chemotherapy. Treatment-related deaths occurred in 1.2% of patients treated with iza-bren and 1.6% of patients treated with chemotherapy. The rates of all grades and grade >3 ILD were low in the iza-bren arm (1.6%/0.8%) and the chemotherapy arm (0.4%/0.4%).

A New Drug Application for iza-bren for the treatment of recurrent or metastatic esophageal squamous cell carcinoma has been accepted by the Center for Drug Evaluation (CDE) under China’s National Medical Products Administration (NMPA) and included in the priority review process.

The PANKU-Breast02 and PANKU-Esophagus01 studies are sponsored by SystImmune’s parent company, Sichuan Biokin Pharmaceutical Co., Ltd. (Biokin), in Mainland China. Outside of China, iza-bren is jointly developed by SystImmune and Bristol Myers Squibb under a collaboration and exclusive license agreement.

About iza-bren

Iza-bren (BL-B01D1) is a bispecific antibody-drug conjugate (ADC) that targets both EGFR and HER3, which are highly expressed in various epithelial cancers and are known to be associated with cancer cell proliferation and survival. Iza-bren’s dual mechanism of action blocks EGFR and HER3 signals to cancer cells, reducing proliferation and survival signals. In addition, upon antibody mediated internalization, iza-bren’s therapeutic novel Topo1i payload is released causing cytotoxic stress that leads to cancer cell death.

The live webinar, "Navigating Lower Cancer-Risk Nodules in High-Risk Patients with Noninvasive CyPath Lung Testing," will take place Tuesday, June 16, at 7 p.m. ET. Clinicians, pulmonologists, oncologists, thoracic surgeons, healthcare professionals and the public are invited to register here (https://bit.ly/3PaFPSR) for the complimentary education event.

"We are seeing a significant increase in patients with indeterminate lung nodules as a result of expanded lung cancer screening and imaging for other conditions. When we consider not only prior smoking history but also an aging population, environmental and occupational exposures, and a better understanding of genetic predispositions, we recognize the real clinical challenges of managing this condition, of distinguishing between malignant and benign nodules," said Gordon Downie, MD, PhD, Chief Medical Officer of bioAffinity Technologies.

"Advanced navigational bronchoscopy serves as an accurate tool to diagnose lung cancer without major surgery, particularly in nodules greater than a centimeter. For smaller nodules, CyPath Lung complements bronchoscopy by helping to risk stratify and identify patients who should move forward with more invasive follow-up," Dr. Downie said.

Moderated by pulmonologist Robert Sussman, MD, former Medical Director of the Atlantic Health System Pulmonary Clinical Research Center, the webinar will feature:

● Vijay K. Gunuganti, MD – Medical oncologist and hematologist at Texas Oncology
● Reginald Carl Baptiste, MD – Thoracic and cardiovascular surgeon at Christus St. Michael Health System
● Sai Karan Vamsi Guda, DO – Director of Interventional Pulmonary at Texas Pulmonary and Critical Care Consultants, P.A.

The panel will discuss how CyPath Lung, a noninvasive test that uses automated flow cytometry and artificial intelligence to analyze the lung microenvironment, is being incorporated into their practice to help:

● aid in the detection of lung cancer at its earliest and most treatable stages
● support surgical and treatment decision-making
● lower overall healthcare costs by reducing unnecessary invasive procedures
● support surveillance of cancer patients after they complete treatment.

"We are honored to collaborate with the Society for Advanced Bronchoscopy to provide clinicians with an opportunity to discuss innovative tools like CyPath Lung that support earlier intervention leading to better patient outcomes," said Maria Zannes, President and CEO of bioAffinity Technologies.

About the Society for Advanced Bronchoscopy

The Society for Advanced Bronchoscopy (SAB) is a national organization dedicated to advancing the field of bronchoscopy through innovation, collaboration and education. Founded to improve patient outcomes, SAB fosters excellence in interpretive skills, technical knowledge, research, and training for advanced bronchoscopic techniques. The society unites a multidisciplinary community – including physicians, advanced practice providers, respiratory therapists, and technologists – to push the boundaries of minimally invasive lung diagnostics and interventions, ultimately transforming the standard of care and enhancing the diagnosis and treatment of respiratory diseases worldwide.

About CyPath Lung

CyPath Lung by bioAffinity Technologies is a noninvasive test designed to improve the early detection of lung cancer in patients at high risk for the disease. CyPath Lung uses advanced flow cytometry and proprietary artificial intelligence (AI) to identify cell populations in patient sputum that indicate malignancy. CyPath Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. In a published clinical trial of high-risk patients, CyPath Lung demonstrated 92% sensitivity, 87% specificity, 88% accuracy and 99% negative predictive value (NPV) in detecting lung cancer in patients at high risk for the disease who had small indeterminate lung nodules less than 20 millimeters. The high NPV gives physicians greater confidence that a negative result is truly negative, potentially sparing patients from unnecessary invasive and costly procedures. CyPath Lung is marketed as a Laboratory Developed Test (LDT) and is not intended for use as a sole diagnostic tool and should be considered alongside other clinical findings.
