Key presentations include:

An oral abstract of the Phase 3 IMforte trial, which showed statistically significant and clinically meaningful survival benefit (progression-free survival (PFS) and overall survival (OS) for the combination of Zepzelca and atezolizumab (Tecentriq) for extensive-stage small cell lung cancer (ES-SCLC) patients receiving treatment in the first-line maintenance setting
A rapid oral abstract of four-year follow-up data, including new OS and translational biomarker data, from an ongoing Phase 2 trial of Ziihera in combination with chemotherapy for the first-line treatment of HER2-positive advanced or metastatic gastroesophageal adenocarcinoma (mGEA)
An oral abstract of efficacy and safety data from a Phase 2 trial of dordaviprone (ONC201), from the recently completed Chimerix acquisition, in prospective clinical trials of adult and pediatric recurrent H3 K27M-mutant diffuse glioma patients
"Along with our partner Roche, we look forward to presenting the potentially practice-changing Phase 3 IMforte trial data of Zepzelca in combination with atezolizumab in the first-line maintenance setting for extensive-stage small cell lung cancer. Data from the trial served as the basis for our recent supplemental New Drug Application submission to FDA, marking an important milestone in our efforts to bring Zepzelca to more patients earlier in their treatment journey," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development, and chief medical officer of Jazz Pharmaceuticals. "We are also eager to share updated long-term outcomes and the first report of median overall survival findings from the Phase 2 trial of Ziihera in combination with standard of care chemotherapy in HER2-positive metastatic gastroesophageal adenocarcinoma, ahead of expected Phase 3 findings later this year, which further reinforce Ziihera’s potential as a differentiated HER2-targeted therapy. Additionally, we are encouraged by new efficacy and safety findings for dordaviprone in adult and pediatric patients with recurrent H3 K27M-mutant diffuse glioma from studies ONC013 and ONC014. We believe strongly in the potential of dordaviprone, a medicine that addresses a significant unmet need with no other FDA-approved therapies for this patient population. These updates build on our commitment to advancing targeted treatment options that address pressing patient needs and may help shape future treatment approaches."

About Zepzelca (lurbinectedin)
Zepzelca is an alkylating drug that binds guanine residues within DNA. This triggers a cascade of events that can affect the activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in disruption of the cell cycle and potentially cell death.1

The FDA approved Zepzelca under accelerated approval in June 2020 for the treatment of adult patients with metastatic SCLC with disease progression on or after platinum-based chemotherapy. The approval is based on overall response rate (ORR) and duration of response demonstrated in an open-label, monotherapy clinical study. In December 2021, Jazz and PharmaMar announced the initiation of LAGOON, a confirmatory Phase 3 clinical trial of Zepzelca for the treatment of patients with relapsed small cell lung cancer. If positive, LAGOON could confirm the benefit of Zepzelca in the treatment of small cell lung cancer (SCLC) when patients progress following 1L treatment with a platinum-based regimen and support full approval in the U.S.

Zepzelca is a prescription medicine used to treat adults with SCLC that has spread to other parts of the body (metastatic) and who have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working. Zepzelca is approved based on response rate and how long the response lasted. Additional studies will further evaluate the benefit of Zepzelca for this use.

Important Safety Information

Myelosuppression

ZEPZELCA can cause myelosuppression. In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA, Grade 3 or 4 neutropenia occurred in 41% of patients, with a median time to onset of 15 days and a median duration of 7 days. Febrile neutropenia occurred in 7% of patients.

Sepsis occurred in 2% of patients and was fatal in 1% (all cases occurred in patients with solid tumors other than SCLC). Grade 3 or 4 thrombocytopenia occurred in 10%, with a median time to onset of 10 days and a median duration of 7 days. Grade 3 or 4 anemia occurred in 17% of patients.
Administer ZEPZELCA only to patients with baseline neutrophil count of at least 1,500 cells/mm3 and platelet count of at least 100,000/mm3.

Monitor blood counts including neutrophil count and platelet count prior to each administration. For neutrophil count less than 500 cells/mm3 or any value less than lower limit of normal, the use of G-CSF is recommended. Withhold, reduce the dose, or permanently discontinue ZEPZELCA based on severity.

Hepatotoxicity

ZEPZELCA can cause hepatotoxicity. In clinical studies of 554 patients with advanced solid tumors receiving ZEPZELCA, Grade 3 elevations of ALT and AST were observed in 6% and 3% of patients, respectively, and Grade 4 elevations of ALT and AST were observed in 0.4% and 0.5% of patients, respectively. The median time to onset of Grade ≥3 elevation in transaminases was 8 days (range: 3 to 49), with a median duration of 7 days.
Monitor liver function tests prior to initiating ZEPZELCA, periodically during treatment, and as clinically indicated. Withhold, reduce the dose, or permanently discontinue ZEPZELCA based on severity.

Extravasation Resulting in Tissue Necrosis

Extravasation of ZEPZELCA resulting in skin and soft tissue injury, including necrosis requiring debridement, can occur. Consider use of a central venous catheter to reduce the risk of extravasation, particularly in patients with limited venous access. Monitor patients for signs and symptoms of extravasation during the ZEPZELCA infusion.

If extravasation occurs, immediately discontinue the infusion, remove the infusion catheter, and monitor for signs and symptoms of tissue necrosis. The time to onset of necrosis after extravasation may vary.

Administer supportive care and consult with an appropriate medical specialist as needed for signs and symptoms of extravasation. Administer subsequent infusions at a site that was not affected by extravasation.

Rhabdomyolysis

Rhabdomyolysis has been reported in patients treated with ZEPZELCA.
Monitor creatine phosphokinase (CPK) prior to initiating ZEPZELCA and periodically during treatment as clinically indicated. Withhold or reduce the dose based on severity.

Embryo-Fetal Toxicity

ZEPZELCA can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise female patients of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 6 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ZEPZELCA and for 4 months after the last dose.
Lactation
There are no data on the presence of ZEPZELCA in human milk, however, because of the potential for serious adverse reactions from ZEPZELCA in breastfed children, advise women not to breastfeed during treatment with ZEPZELCA and for 2 weeks after the last dose.

MOST COMMON ADVERSE REACTIONS

The most common adverse reactions, including laboratory abnormalities, (≥20%) are leukopenia (79%), lymphopenia (79%), fatigue (77%), anemia (74%), neutropenia (71%), increased creatinine (69%), increased alanine aminotransferase (66%), increased glucose (52%), thrombocytopenia (37%), nausea (37%), decreased appetite (33%), musculoskeletal pain (33%), decreased albumin (32%), constipation (31%), dyspnea (31%), decreased sodium (31%), increased aspartate aminotransferase (26%), vomiting (22%), decreased magnesium (22%), cough (20%), and diarrhea (20%).

DRUG INTERACTIONS

Effect of CYP3A Inhibitors and Inducers
Avoid coadministration with a strong or a moderate CYP3A inhibitor (including grapefruit and Seville oranges) as this increases lurbinectedin systemic exposure which may increase the incidence and severity of adverse reactions to ZEPZELCA. If coadministration cannot be avoided, reduce the ZEPZELCA dose as appropriate.
Avoid coadministration with a strong CYP3A inducer as it may decrease systemic exposure to lurbinectedin, which may decrease the efficacy of ZEPZELCA.

GERIATRIC USE
Of the 105 patients with SCLC administered ZEPZELCA in clinical studies, 37 (35%) patients were 65 years of age and older, while 9 (9%) patients were 75 years of age and older. No overall difference in effectiveness was observed between patients aged 65 and older and younger patients.
There was a higher incidence of serious adverse reactions in patients ≥65 years of age than in patients <65 years of age (49% vs 26%, respectively). The serious adverse reactions most frequently reported in patients ≥65 years of age were related to myelosuppression and consisted of febrile neutropenia (11%), neutropenia (11%), thrombocytopenia (8%), and anemia (8%).

About Ziihera (zanidatamab-hrii)
Ziihera (zanidatamab-hrii) is a bispecific HER2-directed antibody that binds to two extracellular sites on HER2. Binding of zanidatamab-hrii with HER2 results in internalization leading to a reduction in HER2 expression of the receptor on the tumor cell surface. Zanidatamab-hrii induces complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). These mechanisms result in tumor growth inhibition and cell death in vitro and in vivo.2 In the United States, Ziihera is indicated for the treatment of adults with previously treated, unresectable or metastatic HER2-positive (IHC 3+) biliary tract cancer (BTC), as detected by an FDA-approved test.2 The U.S. Food and Drug Administration (FDA) granted accelerated approval for this indication based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).2

Zanidatamab is not yet approved outside of the United States.

Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is being developed by Jazz and BeiGene, Ltd. (BeiGene) under license agreements from Zymeworks, which first developed the molecule.

The FDA granted Breakthrough Therapy designation for zanidatamab development in patients with previously treated HER2 gene-amplified BTC, and two Fast Track designations for zanidatamab: one as a single agent for refractory BTC and one in combination with standard-of-care chemotherapy for 1L gastroesophageal adenocarcinoma (GEA). Additionally, zanidatamab has received Orphan Drug designations from FDA for the treatment of BTC and GEA, as well as Orphan Drug designation from the European Medicines Agency for the treatment of BTC and gastric cancer.

Important Safety Information for ZIIHERA

WARNING: EMBRYO-FETAL TOXICITY
Exposure to ZIIHERA during pregnancy can cause embryo-fetal harm. Advise patients
of the risk and need for effective contraception.

WARNINGS AND PRECAUTIONS

Embryo-Fetal Toxicity
ZIIHERA can cause fetal harm when administered to a pregnant woman. In literature reports, use of a HER2-directed antibody during pregnancy resulted in cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death.

Verify the pregnancy status of females of reproductive potential prior to the initiation of ZIIHERA. Advise pregnant women and females of reproductive potential that exposure to ZIIHERA during pregnancy or within 4 months prior to conception can result in fetal harm. Advise females of reproductive potential to use effective contraception during treatment with ZIIHERA and for 4 months following the last dose of ZIIHERA.

Left Ventricular Dysfunction

ZIIHERA can cause decreases in left ventricular ejection fraction (LVEF). LVEF declined by >10% and decreased to <50% in 4.3% of 233 patients. Left ventricular dysfunction (LVD) leading to permanent discontinuation of ZIIHERA was reported in 0.9% of patients. The median time to first occurrence of LVD was 5.6 months (range: 1.6 to 18.7). LVD resolved in 70% of patients.

Assess LVEF prior to initiation of ZIIHERA and at regular intervals during treatment. Withhold dose or permanently discontinue ZIIHERA based on severity of adverse reactions.
The safety of ZIIHERA has not been established in patients with a baseline ejection fraction that is below 50%.

Infusion-Related Reactions

ZIIHERA can cause infusion-related reactions (IRRs). An IRR was reported in 31% of 233 patients treated with ZIIHERA as a single agent in clinical studies, including Grade 3 (0.4%), and Grade 2 (25%). IRRs leading to permanent discontinuation of ZIIHERA were reported in 0.4% of patients. IRRs occurred on the first day of dosing in 28% of patients; 97% of IRRs resolved within one day.

Prior to each dose of ZIIHERA, administer premedications to prevent potential IRRs. Monitor patients for signs and symptoms of IRR during ZIIHERA administration and as clinically indicated after completion of infusion. Have medications and emergency equipment to treat IRRs available for immediate use.

If an IRR occurs, slow, or stop the infusion, and administer appropriate medical management. Monitor patients until complete resolution of signs and symptoms before resuming. Permanently discontinue ZIIHERA in patients with recurrent severe or life-threatening IRRs.

Diarrhea

ZIIHERA can cause severe diarrhea.
Diarrhea was reported in 48% of 233 patients treated in clinical studies, including Grade 3 (6%) and Grade 2 (17%). If diarrhea occurs, administer antidiarrheal treatment as clinically indicated. Perform diagnostic tests as clinically indicated to exclude other causes of diarrhea. Withhold or permanently discontinue ZIIHERA based on severity.

ADVERSE REACTIONS

Serious adverse reactions occurred in 53% of 80 patients with unresectable or metastatic HER2-positive BTC who received ZIIHERA. Serious adverse reactions in >2% of patients included biliary obstruction (15%), biliary tract infection (8%), sepsis (8%), pneumonia (5%), diarrhea (3.8%), gastric obstruction (3.8%), and fatigue (2.5%). A fatal adverse reaction of hepatic failure occurred in one patient who received ZIIHERA.
The most common adverse reactions in 80 patients with unresectable or metastatic HER2-positive BTC who received ZIIHERA (≥20%) were diarrhea (50%), infusion-related reaction (35%), abdominal pain (29%), and fatigue (24%).

USE IN SPECIFIC POPULATIONS

Pediatric Use

Safety and efficacy of ZIIHERA have not been established in pediatric patients.

Geriatric Use

Of the 80 patients who received ZIIHERA for unresectable or metastatic HER2-positive BTC, there were 39 (49%) patients 65 years of age and older. Thirty-seven (46%) were aged 65-74 years old and 2 (3%) were aged 75 years or older.
No overall differences in safety or efficacy were observed between these patients and younger adult patients.

About Vyxeos (daunorubicin and cytarabine)
Vyxeos is a liposomal combination of daunorubicin, an anthracycline topoisomerase inhibitor, and cytarabine, a nucleoside metabolic inhibitor, that is indicated for the treatment of newly-diagnosed therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC) in adults and pediatric patients 1 year and older. For more information about Vyxeos in the United States, please visit View Source

Important Safety Information

WARNING: DO NOT INTERCHANGE WITH OTHER DAUNORUBICIN AND/OR CYTARABINE-
CONTAINING PRODUCTS

VYXEOS has different dosage recommendations than daunorubicin hydrochloride
injection, cytarabine injection, daunorubicin citrate liposome injection, and cytarabine
liposome injection. Verify drug name and dose prior to preparation and administration to
avoid dosing errors.

Contraindications

VYXEOS is contraindicated in patients with a history of serious hypersensitivity reactions to cytarabine, daunorubicin, or any component of the formulation.

Warnings and Precautions

Hemorrhage

Serious or fatal hemorrhage events, including fatal CNS hemorrhages, associated with prolonged thrombocytopenia, have occurred with VYXEOS. The overall incidence (grade 1-5) of hemorrhagic events was 74% in the VYXEOS arm and 56% in the control arm. The most frequently reported hemorrhagic event was epistaxis (36% in VYXEOS arm and 18% in control arm). Grade 3 or greater events occurred in 12% of VYXEOS-treated patients and in 8% of patients in the control arm. Fatal treatment-emergent CNS hemorrhage not in the setting of progressive disease occurred in 2% of patients in the VYXEOS arm and in 0.7% of patients in the control arm. Monitor blood counts regularly and administer platelet transfusion support as required.

Cardiotoxicity

VYXEOS contains daunorubicin, which has a known risk of cardiotoxicity. This risk may be increased in patients with prior anthracycline therapy, preexisting cardiac disease, previous radiotherapy to the mediastinum, or concomitant use of cardiotoxic drugs. Assess cardiac function prior to VYXEOS treatment and repeat prior to consolidation and as clinically required. Discontinue VYXEOS in patients with impaired cardiac function unless the benefit of initiating or continuing treatment outweighs the risk. VYXEOS is not recommended in patients with cardiac function that is less than normal.

Total cumulative doses of non-liposomal daunorubicin greater than 550 mg/m2 have been associated with an increased incidence of drug-induced congestive heart failure. The tolerable limit appears lower (400 mg/m2) in patients who received radiation therapy to the mediastinum. Calculate the lifetime cumulative anthracycline exposure prior to each cycle of VYXEOS. VYXEOS is not recommended in patients whose lifetime anthracycline exposure has reached the maximum cumulative limit.

Hypersensitivity Reactions

Serious or fatal hypersensitivity reactions, including anaphylactic reactions, have been reported with daunorubicin and cytarabine. Monitor patients for hypersensitivity reactions. If a mild or moderate hypersensitivity reaction occurs, interrupt or slow the rate of infusion with VYXEOS and manage symptoms. If a severe or life-threatening hypersensitivity reaction occurs, discontinue VYXEOS permanently, treat the symptoms, and monitor until symptoms resolve.

Copper Overload

VYXEOS contains copper. Consult with a hepatologist and nephrologist with expertise in managing acute copper toxicity in patients with Wilson’s disease treated with VYXEOS. Monitor total serum copper, serum non-ceruloplasmin-bound copper, 24-hour urine copper levels, and serial neuropsychological examinations during VYXEOS treatment in patients with Wilson’s disease or other copper-related metabolic disorders. Use only if the benefits outweigh the risks. Discontinue in patients with signs or symptoms of acute copper toxicity.

Tissue Necrosis

Daunorubicin has been associated with severe local tissue necrosis at the site of drug extravasation. Administer VYXEOS by the intravenous route only. Confirm patency of intravenous access before administration. Do not administer by intramuscular or subcutaneous route.

Embryo-Fetal Toxicity

VYXEOS can cause embryo-fetal harm when administered to a pregnant woman. Patients should avoid becoming pregnant while taking VYXEOS. If VYXEOS is used during pregnancy or if the patient becomes pregnant while taking VYXEOS, apprise the patient of the potential risk to a fetus. Advise females and males of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of VYXEOS.

MOST COMMON ADVERSE REACTIONS

The most common adverse reactions (incidence ≥25%) are hemorrhagic events (74%), febrile neutropenia (70%), rash (56%), edema (55%), nausea (49%), mucositis (48%), diarrhea (48%), constipation (42%), musculoskeletal pain (43%), fatigue (39%), abdominal pain (36%), dyspnea (36%), headache (35%), cough (35%), decreased appetite (33%), arrhythmia (31%), pneumonia (31%), bacteremia (29%), chills (27%), sleep disorders (26%), and vomiting (25%).

About ABD-147

ABD-147 is a targeted radiopharmaceutical biologic therapy designed to deliver Actinium-225 (225Ac), a highly potent alpha-emitting radioisotope, to solid tumors expressing delta-like ligand 3 (DLL3) with high affinity. DLL3 is a protein in the Notch pathway that is critical for the development and regulation of neuroendocrine versus epithelial cell differentiation in the lungs. In certain high grade neuroendocrine carcinomas including small cell lung cancer (SCLC), DLL3 is upregulated and specifically expressed on the cell surface in more than 80% of cases. In contrast, DLL3 is absent or very rarely expressed on the surface of nonmalignant cells. Given the high specificity of DLL3 expression on cancer cells and the distinct mechanism of action, DLL3 represents a compelling target for treating SCLC and other DLL3+ solid tumors with targeted radiotherapy.

The U.S. Food and Drug Administration (FDA) has granted Fast Track designation to ABD-147 for the treatment of patients with extensive stage small cell lung cancer (ES-SCLC) who have progressed on or after platinum-based chemotherapy and Orphan Drug Designation to ABD-147 for the treatment of neuroendocrine carcinoma. ABD-147 is currently being evaluated in a first-in-human Phase 1 clinical trial in patients with SCLC or large cell neuroendocrine carcinoma of the lung who have previously received platinum-based therapy.

About Small Cell Lung Cancer and Large Cell Neuroendocrine Carcinoma

The global incidence for SCLC and LCNEC has been reported to represent approximately 325,000 patients and is expected to increase 4% annually through 2029. In the U.S., the incidence has been reported to be approximately 35,000 new cases annually. Fifteen percent of all lung cancer cases are high-grade neuroendocrine cancers. These cancers have the most aggressive clinical course of any type of pulmonary tumor and often metastasize to other parts of the body, including the brain, liver and bone. Without treatment, the median survival from diagnosis has been reported to be only two to four months. With treatment, the overall survival at five years is 5% to 10% for SCLC, and 15% to 25% for LCNEC. SCLC and LCNEC generally carry a poor prognosis and new treatment options are urgently needed.

About ABD-320

ABD-320 is a targeted radiopharmaceutical biologic therapy engineered to deliver Actinium-225 (225Ac) to solid tumors expressing 5T4. This oncofetal protein is rarely expressed in normal adult tissues but has been shown to be up-regulated in multiple cancer types, including colorectal, head and neck, non-small cell lung, pancreatic, gastric, mesothelioma, bladder, renal, cervical, ovarian, and breast cancers. By driving tumor cell migration and survival, 5T4 plays a key role in cancer progression and is associated with advanced disease, increased invasiveness, and poor clinical outcomes in solid tumors. ABD-320 was developed leveraging Abdera’s ROVEr platform and is custom-engineered to achieve an ideal balance of tumor uptake and retention while avoiding systemic radiotoxicities. Preclinical data with ABD-320 demonstrates potent anticancer activity. ABD-320 represents the first radiopharmaceutical therapy in development to address 5T4.

Cytovation Raises US$6m to Advance Phase 2 Development of CY-101 in Adrenocortical Carcinoma to First Clinical Readouts

On April 23, 2025 Cytovation ASA, a clinical stage oncology company focused on the development of its first-in-class bifunctional peptide CY-101, reported that it has raised NOK62 million (US$6m) largely from existing investors, led by Sandwater (Press release, Cytovation, APR 23, 2025, View Source;utm_medium=rss&utm_campaign=cytovation-raises-us6m-to-advance-phase-2-development-of-cy-101-in-adrenocortical-carcinoma-to-first-clinical-readouts [SID1234652053]).

These funds will be used to advance CY-101 into a multi-national Phase 2 clinical trial in patients with adrenocortical carcinoma due to start in late 2025 and with first clinical readouts expected in 2026. The trial will be conducted through a partnership between Cytovation, Cancer Research UK and the Norwegian Cancer Society under an agreement announced in January 2025 (click here for press release).

CY-101, a membranolytic inhibitor of the Wnt/β-catenin pathway, has demonstrated early signs of antitumor activity in the Phase 1 CICILIA trial – particularly in tumors with dysregulated Wnt/β-catenin signaling.

New preclinical data being presented at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting (Chicago, IL; April 25-30, 2025) by Cytovation and its collaborators at the Luxembourg Institute of Health, provide further insights into the mechanistic basis of CY-101’s activity.

The studies, conducted in in vivo immune-refractory models of ACC, colorectal carcinoma (CRC) and melanoma, demonstrated that CY-101 eliminates ACC and CRC tumors, enhances the efficacy of anti-PD-1 activity and triggers a systemic antitumor immune response.

These findings support the potential of CY-101 as a novel therapeutic for difficult-to-treat cancers such as ACC, and more broadly for tumors with dysregulated Wnt/β-catenin signaling, like CRC and hepatocellular carcinoma (HCC), among others.

"As we continue to explore the novel mechanism of action of CY-101 and its translation into meaningful clinical activity, our conviction in its potential to address tumors driven by the Wnt/β-catenin pathway only grows stronger," said Lars Prestegarden, CEO of Cytovation. "We are grateful for the continued support of our investors, whose confidence – alongside the strength of our outstanding partners – positions us well to advance CY-101 into Phase 2 trials and generate impactful clinical data."

Ivonescimab in Combination with Chemotherapy Achieves Statistically Significant Superiority in PFS vs. Tislelizumab (PD-1 Inhibitor) Plus Chemotherapy in 1L Treatment of Patients with Squamous NSCLC in HARMONi-6 Study Conducted by Akeso in China

On April 23, 2025 Summit Therapeutics Inc. (NASDAQ: SMMT) ("Summit," "we," or the "Company") today noted that Akeso, Inc. (Akeso, HKEX Code: 9926.HK) reported that the Phase III clinical trial, HARMONi-6 or AK112-306, met its primary endpoint of progression-free survival (PFS) (Press release, Summit Therapeutics, APR 23, 2025, View Source [SID1234652085]). HARMONi-6 is evaluating ivonescimab in combination with platinum-based chemotherapy compared with tislelizumab, a PD-1 inhibitor, in combination with platinum-based chemotherapy in patients with locally advanced or metastatic squamous non-small cell lung cancer (NSCLC) irrespective of PD-L1 expression. HARMONi-6 is a single region, multi-center, Phase III study conducted in China sponsored by Akeso with all relevant data exclusively generated, managed, and analyzed by Akeso.

At a prespecified interim analysis conducted by an Independent Data Monitoring Committee, ivonescimab plus chemotherapy demonstrated a statistically significant and clinically meaningful improvement in PFS by blinded independent central radiology review committee (BICR) compared to tislelizumab plus chemotherapy. The PFS benefit was demonstrated in patients with either PD-L1-positive or PD-L1-negative tumors. Akeso noted that no new safety signals were identified in this Phase III study. The full data set for HARMONi-6 is planned to be presented at an upcoming major medical conference later this year.

Prior to HARMONi-6, there were no known Phase III clinical trials in NSCLC which have shown a statistically significant improvement compared to PD-(L)1 inhibitor therapy in combination with chemotherapy in a head-to-head setting. Following the success of Akeso’s HARMONi-2 study in China where the PFS benefit was observed in a monotherapy setting for patients whose squamous or non-squamous tumors were positive for PD-L1 expression, this is the second time in which ivonescimab-based regimens have become the first known investigational therapy to demonstrate a statistically significant benefit compared to standard-of-care PD-(L)1 inhibitor-based regimens.

"Ivonescimab has the opportunity to make a significant, positive difference, potentially providing patients with the next generation of treatment options against insidious solid tumors beginning with non-small cell lung cancer," stated Dr. Maky Zanganeh, President and Co-Chief Executive Officer of Summit.

Summit is currently enrolling patients in the HARMONi-3 study. HARMONi-3 is a multiregional Phase III clinical trial sponsored by Summit which is intended to evaluate ivonescimab combined with chemotherapy compared to pembrolizumab, an anti-PD-1 antibody, combined with chemotherapy in patients with first-line metastatic, squamous and non-squamous NSCLC. HARMONi-3 is currently enrolling patients globally and is conducted with registrational intent for the United States and other regions within Summit’s license territories.

"Our aligned mission with Akeso seeks to bring ivonescimab to as many patients around the world who can potentially benefit as quickly as possible," added Robert W. Duggan, Chairman and Co-Chief Executive Officer of Summit. "We are incredibly proud of Akeso’s accomplishment with the HARMONi-6 trial."

About Ivonescimab

Ivonescimab, known as SMT112 in Summit’s license territories, North America, South America, Europe, the Middle East, Africa, and Japan, and as AK112 in China and Australia, is a novel, potential first-in-class investigational bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule. Ivonescimab displays unique cooperative binding to each of its intended targets with multifold higher affinity to PD-1 when in the presence of VEGF.

This could differentiate ivonescimab as there is potentially higher expression (presence) of both PD-1 and VEGF in tumor tissue and the tumor microenvironment (TME) as compared to normal tissue in the body. Ivonescimab’s tetravalent structure (four binding sites) enables higher avidity (accumulated strength of multiple binding interactions) in the TME (Zhong, et al, SITC (Free SITC Whitepaper), 2023). This tetravalent structure, the intentional novel design of the molecule, and bringing these two targets into a single bispecific antibody with cooperative binding qualities have the potential to direct ivonescimab to the tumor tissue versus healthy tissue. The intent of this design, together with a half-life of 6 to 7 days after the first dose (Zhong, et al, SITC (Free SITC Whitepaper), 2023), is to improve upon previously established efficacy thresholds, in addition to side effects and safety profiles associated with these targets.

Ivonescimab was engineered by Akeso Inc. (HKEX Code: 9926.HK) and is currently engaged in multiple Phase III clinical trials. Over 2,300 patients have been treated with ivonescimab in clinical studies globally.

Summit has begun its clinical development of ivonescimab in non-small cell lung cancer (NSCLC), commencing enrollment in 2023 in two multi-regional Phase III clinical trials, HARMONi and HARMONi-3, and the Company has begun to activate clinical trial sites in the United States for HARMONi-7.

HARMONi is a Phase III clinical trial which intends to evaluate ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with a 3rd generation EGFR TKI (e.g., osimertinib). Enrollment in HARMONi was completed in the second half of 2024, and top-line results are expected to be announced in the middle of this year.

HARMONi-3 is a Phase III clinical trial which is intended to evaluate ivonescimab combined with chemotherapy compared to pembrolizumab combined with chemotherapy in patients with first-line metastatic, squamous and non-squamous NSCLC.

HARMONi-7 is a Phase III clinical trial which is intended to evaluate ivonescimab monotherapy compared to pembrolizumab monotherapy in patients with first-line metastatic NSCLC whose tumors have high PD-L1 expression.

In addition, Akeso has recently had positive read-outs in three single-region (China), randomized Phase III clinical trials for ivonescimab in NSCLC: HARMONi-A, HARMONi-2, and HARMONi-6.

HARMONi-A was a Phase III clinical trial which evaluated ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with an EGFR TKI.

HARMONi-2 is a Phase III clinical trial evaluating monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression.

HARMONi-6 is a Phase III clinical trial evaluating ivonescimab in combination with platinum-based chemotherapy compared with tislelizumab, an anti-PD-1 antibody, in combination with platinum-based chemotherapy in patients with locally advanced or metastatic squamous non-small cell lung cancer (NSCLC), irrespective of PD-L1 expression.

Ivonescimab is an investigational therapy that is not approved by any regulatory authority in Summit’s license territories, including the United States and Europe. Ivonescimab was approved for marketing authorization in China in May 2024. Ivonescimab was granted Fast Track designation by the US Food & Drug Administration (FDA) for the HARMONi clinical trial setting.
