Phase Ⅲ Study of lvonescimab plus chemotherapy versus Tislelizumab plus chemotherapy as Firstline Treatment for advanced squamous non-small cell lung cancer (HARMONi-6)

Speakers: Professor Shun Lu (Shanghai, China)
Session: Presidential Symposium 2 Proffered Paper session
Presentation Time: 16:30 -16:42 (CEST) Sun. 19.10.2025
Room: Berlin Auditorium – Hub 27
The upcoming detailed results from the HARMONi-6 study, to be presented at ESMO (Free ESMO Whitepaper) 2025, will provide a comprehensive overview of the exceptional efficacy and favorable safety profile of ivonescimab in combination with chemotherapy for the treatment of first line advanced squamous NSCLC. These findings will further underscore ivonescimab’s role in advancing treatment strategies beyond first-generation immuno-oncology therapies.

The HARMONi-6 study represents the third Phase III trial of ivonescimab in NSCLC, showing significant positive outcomes. This trial is particularly important as it introduces an antiangiogenic mechanism-based therapy for sq-NSCLC, a subtype previously lacking such therapeutic options. Notably, it is the second Phase III head-to-head trial where ivonescimab has outperformed a PD-1 inhibitor-based regimen, reinforcing its breakthrough clinical value.

The promising results thus far affirm that ivonescimab provides significant advancements in clinical treatment for NSCLC, whether compared to PD-1 monotherapy, PD-1 plus chemotherapy, or VEGF-targeted therapies. The consistent superiority observed in these comparisons highlights ivonescimab’s potential to redefine treatment paradigms in oncology.

In April 2025, Akeso announced that the topline results from the registrational Phase III study, HARMONi-6, met its primary endpoint of progression-free survival (PFS), as confirmed by the Independent Data Monitoring Committee (IDMC). The results showed statistically significant and clinically meaningful improvements in PFS for ivonescimab plus chemotherapy compared to tislelizumab plus chemotherapy. In the intent-to-treat (ITT) population, patients receiving ivonescimab plus chemotherapy showed significantly superior PFS benefits compared to the control group. This PFS improvement was consistently observed across all subgroups, regardless of PD-L1 expression status.

On July 28, 2025, the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) accepted the supplemental New Drug Application (sNDA) for ivonescimab in combination with chemotherapy as a first-line treatment for advanced sq-NSCLC.

Cadonilimab (Cado) plus chemotherapy (chemo) versus chemotherapy as first-line (1L) treatment for advanced gastric or gastroesophageal junction (G/GEJ) adenocarcinoma: final results of the Phase Ⅲ COMPASSION-15 trial
Speaker: Professor Shen Lin, Peking University Cancer Hospital
Presentation Format: Mini Oral Session
Abstract Number: 2098MO
Presentation Time: 10:45–10:50 AM (CEST) , Saturday, 18 October 2025
The final results of the COMPASSION-15 study, to be presented at ESMO (Free ESMO Whitepaper) 2025, will further validate the groundbreaking clinical value of the cadonilimab-based regimen, reinforcing its potential as a transformative therapeutic option for advanced gastric cancer.

Preliminary findings from the COMPASSION-15 study were first presented by Professor Ji Jiafu of Peking University Cancer Hospital at the 2024 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. These results garnered international recognition and were subsequently published in the esteemed Nature Medicine journal. Due to the positive clinical results, cadonilimab received approval from the NMPA in September 2024 for the first-line treatment of advanced gastric cancer. Furthermore, the regimen was included as the only immunotherapy strategy with a Category I Recommendation (Level IA Evidence) in the 2025 CSCO Gastric Cancer Guidelines, facilitating its widespread adoption in clinical practice.

On September 22, 2025 Astrazeneca reported that Koselugo (selumetinib), an oral, selective MEK inhibitor, has been recommended for approval in the European Union (EU) for the treatment of symptomatic, inoperable plexiform neurofibromas (PN) in adult patients with neurofibromatosis type 1 (NF1) (Press release, AstraZeneca, SEP 22, 2025, View Source [SID1234656140]).

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from KOMET, the largest and only placebo-controlled global Phase III trial in this patient population, which were presented at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and published in The Lancet.1

In the primary analysis of the trial, Koselugo showed a statistically significant objective response rate (ORR) of 20% (n=14/71, 95% CI: 11.2, 30.9) compared to 5% with placebo (n=4/74, 95% CI: 1.5, 13.3; p=0.01) by cycle 16.1

NF1 is a rare, progressive, genetic condition usually diagnosed in early childhood, but often progressing into adulthood, that can impact every organ system.2,3 Up to 50% of people living with NF1 may develop a type of non-malignant tumour called PN that may affect the brain, spinal cord and nerves.3,4 PN may appear later in a person’s life and can grow and become large, leading to pain, disfigurement and muscle weakness, among other debilitating symptoms.3,4

Prof. Pierre Wolkenstein, MD, PhD, Head of the Department of Dermatology at Henri Mondor Hospital, APHP, Paris East University (UPEC), and National Coordinating Investigator of the KOMET trial in Europe, said: "For adults with NF1, tumour growth doesn’t stop at childhood and can rapidly progress or develop into adulthood, impacting physical, emotional and social well-being. The positive recommendation by the CHMP for Koselugo in adults underscores the urgent need for additional targeted treatments for this patient population. When approved, Koselugo could offer a treatment option for adult patients and continuity of care across age groups, supported by established clinical experience and practice among doctors managing this lifelong condition."

Marc Dunoyer, Chief Executive Officer, Alexion, said: "The CHMP positive opinion of Koselugo in adults with NF1 PN builds on more than a decade of global clinical and real-world experience, reflecting the unmatched body of evidence supporting the safety profile and efficacy of Koselugo. As demonstrated by the results from KOMET, the largest and only placebo-controlled, double-blind global Phase III trial in an adult population, we continue to advance the pioneering legacy of Koselugo, which set the treatment standard in NF1 PN, to reach even more people worldwide."

The safety profile of Koselugo in the KOMET Phase III trial was consistent with its known profile and established use in paediatric patients.1

Koselugo has been recently approved in Japan and other countries for the treatment of adult patients with NF1 who have symptomatic, inoperable PN based on data from the KOMET Phase III trial, and additional regulatory reviews are ongoing.

Notes

NF1
NF1 is a rare, progressive, genetic condition that is caused by a spontaneous or inherited mutation in the NF1 gene.2,3 NF1 is associated with a variety of symptoms, including soft lumps on and under the skin (cutaneous neurofibromas) and, in up to 50% of patients, tumours called plexiform neurofibromas (PN) may develop on the nerve sheaths.3,4 These PN can cause clinical issues such as disfigurement, motor dysfunction, pain, airway dysfunction, visual impairment and bladder or bowel dysfunction.3,4

KOMET
KOMET is a global Phase III randomised, double-blind, placebo-controlled, multicentre trial designed to evaluate the efficacy and safety of Koselugo in adults with NF1 who have symptomatic, inoperable PN. The trial enrolled 145 adults from 13 countries across North America, South America, Europe, Asia and Australia, with participants’ baseline characteristics, including gender and distribution of PN, reflective of the global adult NF1 patient population. Patients were enrolled and randomised to receive Koselugo or placebo (1:1) for 12 28-day cycles. Participants were required to have diagnosis of NF1, at least one symptomatic, inoperable PN measurable by volumetric MRI analysis, chronic PN pain score documented during screening, adequate organ and marrow function and stable chronic PN pain medication use at enrolment.1,5

The primary endpoint is confirmed objective response rate (ORR) by cycle 16 as assessed by ICR. ORR is defined as the percentage of patients with confirmed complete response (disappearance of PNs) or partial response (at least 20% reduction in tumour volume). Secondary endpoints include improved PN-related pain and health-related quality of life (HRQoL) at cycle 12.1,5

After 12 cycles, patients on placebo were switched to Koselugo and patients on Koselugo remained on treatment for an additional 12 cycles. Patients who had the opportunity to complete 24 cycles of treatment have the option to participate in a long-term extension period and continue to receive Koselugo.1,5

Koselugo
Koselugo (selumetinib) is a kinase inhibitor that blocks specific enzymes (MEK1 and MEK2), which are involved in stimulating cells to grow. In NF1, these enzymes are overactive, causing tumour cells to grow in an unregulated way creating so-called plexiform neurofibromas (PN). By blocking these enzymes, Koselugo slows down the growth of tumour cells and, therefore, the PN growth. 
 
Koselugo is approved in the US, EU, Japan, China and other countries for the treatment of certain paediatric patients with NF1 who have symptomatic, inoperable PN.

Koselugo is approved in Japan and other countries for the treatment of adult patients with NF1 who have symptomatic, inoperable PN, and additional regulatory reviews are ongoing

Koselugo has been granted Orphan Drug Designation in the US, EU, Japan and other countries for the treatment of NF1.

About RET-fusion positive NSCLC

RET gene fusions represent one of the rare yet significant driver mutation types in NSCLC. In Chinese NSCLC patients, the incidence of RET gene fusions ranges from 1.4% to 2.5%[1]. Patients with RET fusions derive limited benefit from conventional treatments. In recent years, the emergence of novel highly selective inhibitors has led to breakthroughs in the clinical management of advanced RET-fusion positive NSCLC patients. However, their therapeutic benefits are limited, in part, by acquired RET drug-resistant mutations and safety issues such as hypertension and hematological toxicity, underscoring the need for novel selective RET inhibitors with improved safety and better efficacy against drug-resistant mutations.

About A400/EP0031

A400/EP0031 is a novel next-generation selective RET inhibitor for NSCLC, medullary thyroid cancer (MTC) and other solid tumors with a high prevalence of RET alterations. The Company is currently conducting a phase 1b/2 clinical study for RET+ MTC and solid tumor in China. The results from the Phase 1 study of A400/EP0031 in patients with advanced RET-mutant MTC were presented at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting.

In March 2021, the Company granted Ellipses Pharma Limited, a U.K.-based international oncology drug development company, an exclusive license to develop, manufacture and commercialize this agent outside Greater China and certain Asian countries under the code EP0031.

In March 2024, it was announced that EP0031/A400 was granted Fast Track designation by the Food and Drug Administration (FDA) for the treatment of RET-fusion positive NSCLC. In April 2024, EP0031/A400 was cleared by the FDA to progress into Phase 2 clinical development and is now open in the United States, United Kingdom, Europe and United Arab Emirates.
