IPH4502 is a novel and differentiated topoisomerase I inhibitor ADC designed to precisely target Nectin-4, a cell adhesion molecule that is overexpressed in several types of solid tumors, including urothelial carcinoma (UC), breast cancer, non-small cell lung cancer or gastro-intestinal cancer. IPH4502 targets tumors with a wide range of Nectin-4 expression, supporting its development beyond UC. IPH4502 differentiated topoisomerase I inhibitor payload supports its potential in patients with tumors resistant to MMAE-ADC.

The Phase 1, open-label, multi-center study, includes a Part 1 Dose Escalation and a Part 2 Dose Optimization, and will assess the safety, tolerability, and preliminary efficacy of IPH4502 as a single agent in advanced solid tumors known to express Nectin-4, including but not limited to urothelial carcinoma, non-small cell lung, breast, ovarian, gastric, esophageal, and colorectal cancers. The study plans to enroll approximately 105 patients.

"We are thrilled to initiate the Phase 1 study with IPH4502, a promising therapy for patients with advanced solid tumors known to express Nectin-4," said Dr Shiraj Sen, Medical Oncologist and Phase 1 Investigator, Director of Clinical Research, NEXT Oncology-Dallas. "IPH4502 is uniquely designed to target tumors with both high and low expression of Nectin-4, offering hope for improved outcomes in a population where effective treatment options are limited, and relapses occur frequently. This study represents an important step forward in advancing innovative care for these patients."

"The initiation of this Phase 1 trial represents a significant milestone for Innate Pharma as our clinical stage pipeline now includes targeted ADCs. We are optimistic about the potential of IPH4502 to address unmet needs in the treatment of advanced solid tumors, with a well differentiated Nectin-4 targeting and the promise of ADC technology to provide a new therapeutic option for patients," added Dr Sonia Quaratino, Chief Medical Officer at Innate Pharma.

More information about the trial can be found on clinicaltrials.gov.

"We are encouraged by the speed in which the EMA accepted our marketing authorization application and determined it would begin its assessment of our innovative treatment for this serious condition, just nine months after it was first approved by the FDA for use in the United States," said Dr. Patrick Soon-Shiong, Founder, Executive Chairman and Global Chief Scientific and Medical Officer of ImmunityBio. "Along with our submission to the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA), this action by the EMA is strong evidence of the momentum for putting ANKTIVA+BCG into the hands of physicians who are treating patients with NMIBC."

The EMA submission is based on the ongoing QUILT 3.032 study in which the complete response rate for the 100 evaluable patients in Cohort A as of the July 15, 2024 cut-off was 71%. In these responders, the range of duration of response is 0.03 to 54 months and is ongoing. These prolonged duration of complete response results beyond four years with ANKTIVA and BCG exceed the benchmark of 18 months for the magnitude of meaningful clinical results suggested by a panel of experts at the International Bladder Cancer Group.

About ANKTIVA

The cytokine interleukin-15 (IL-15) plays a crucial role in the immune system by affecting the development, maintenance, and function of key immune cells—NK and CD8+ killer T cells—that are involved in killing cancer cells. By activating NK cells, ANKTIVA overcomes the tumor escape phase of clones resistant to T cells and restores memory T cell activity with resultant prolonged duration of complete response.

ANKTIVA is a first-in-class IL-15 agonist IgG1 fusion complex, consisting of an IL-15 mutant (IL-15N72D) fused with an IL-15 receptor alpha, which binds with high affinity to IL-15 receptors on NK, CD4+, and CD8+ T cells. This fusion complex of ANKTIVA mimics the natural biological properties of the membrane-bound IL-15 receptor alpha, delivering IL-15 by dendritic cells and drives the activation and proliferation of NK cells with the generation of memory killer T cells that have retained immune memory against these tumor clones. The proliferation of the trifecta of these immune killing cells and the activation of trained immune memory results in immunogenic cell death, inducing a state of equilibrium with durable complete responses. ANKTIVA has improved pharmacokinetic properties, longer persistence in lymphoid tissues, and enhanced anti-tumor activity compared to native, non-complexed IL-15 in-vivo.

ANKTIVA was approved by the FDA in 2024 for BCG-unresponsive non-muscle invasive bladder cancer CIS with or without papillary tumors. For more information, visit Anktiva.com.

According to the latest data collected by the European Cancer Information System (click here), a total of 24,599 new cases of breast cancer were diagnosed in Poland in 2022, which is the most common cancer diagnosed in women, representing approximately 25% of all cancers in women. Breast cancer is the second leading cause of death from cancer in women in Poland with 8,723 deaths in 2022.

The Company is collaborating with Dr. Piotr Wysocki, who is leading one of the largest academic and private breast cancer research networks in Poland, where 9 to 11 sites have agreed to participate in FLAMINGO-01. These sites were approved by Polish authorities, which has led to site initiation visits and the treatment of the first patient in Poland in 2024.

Dr. Wysocki is Professor of Medicine and Head of Department of Oncology at Jagiellonian University Hospital in Krakow Poland. He has research interests in the development of novel apheresis-based cancer therapies, clinical application of metronomic chemotherapy, metronomic chemo-endocrine and chemo-targeted therapies for the treatment of breast, prostate, and ovarian cancers.

CEO Snehal Patel commented, "Poland has a reputation for large treatment centers with high enrollment and standard of care. We look forward to working with Dr. Wysocki who is serving as the national principal investigator for Poland in FLAMINGO-01. We have been impressed with the sites that we have visited to date. In addition, we may have an opportunity to offer our study to Ukrainians who may have been displaced and now reside in Poland."

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US clinical sites from university-based hospitals and cooperative networks with plans to expand into Europe and to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients will be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types will be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.
