What is the purpose of this trial?

This trial tests a new treatment, IPH4502, for individuals with advanced solid tumors containing the protein Nectin-4. This first-time study in humans aims to assess the drug's safety and potential effectiveness. The trial seeks participants whose cancer cannot be surgically removed and who have no other known effective treatment options. Participants should have previously received some form of cancer treatment but still have measurable disease. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, such as systemic corticosteroids, immunosuppressive agents, and specific CYP 3A4 inhibitors or inducers, at least 14 days before starting the study drug. If you are on these medications, you may need to stop or adjust them before participating.

Is there any evidence suggesting that IPH4502 is likely to be safe for humans?

Research shows that IPH4502 is undergoing its first human trials, so detailed safety information is not yet available. However, early lab studies demonstrated its effectiveness against various cancer types. These studies guide scientists in assessing whether a treatment might be safe for human trials.

As a Phase 1 trial, the primary goal is to evaluate the safety of IPH4502 and observe participants' reactions. Phase 1 trials typically involve close monitoring for any side effects, with doctors and researchers carefully observing to ensure participant safety. Although detailed safety results from human trials are not yet available, the initiation of a Phase 1 trial indicates that early tests were promising enough to proceed with human testing. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

IPH4502 is unique because it represents a potential new approach to cancer treatment. Unlike traditional chemotherapy or targeted therapies, which often attack cancer cells directly or interfere with specific proteins involved in cancer growth, IPH4502 is designed to enhance the body's immune response against cancer cells. This novel mechanism of action could offer a more precise attack on cancer, potentially reducing side effects associated with conventional treatments. Researchers are excited about IPH4502 because it may provide a new avenue for treating cancer, especially for patients who have limited responses to existing therapies.

What evidence suggests that IPH4502 might be an effective treatment for cancer?

Research has shown that IPH4502 is very effective in lab studies against several types of cancer, including triple-negative breast cancer, head and neck cancer, and esophageal cancer. It targets a protein called Nectin-4, often found in large amounts in certain tumors. By focusing on this protein, the drug may attack cancer cells more effectively. Although research in humans remains in the early stages, these initial lab results are promising for treating cancers with high levels of Nectin-4. ^{1 2 3 6 7}

Are You a Good Fit for This Trial?

This trial is for patients with advanced solid tumors that express a protein called Nectin-4. Specific eligibility details are not provided, but typically participants must be adults with measurable disease who have tried standard treatments without success.

Wild-type isocitrate dehydrogenase 2 (IDH2) is crucial for protecting colorectal cancer (CRC) cells from oxidative damage, and its suppression leads to increased DNA damage and cell senescence.

Inhibiting IDH2 not only reduces CRC cell growth but also makes these cells more sensitive to DNA-damaging drugs like oxaliplatin, suggesting a potential new strategy for cancer treatment by targeting metabolic pathways.

In a phase 3 trial involving 1150 patients with advanced non-small-cell lung cancer (NSCLC), the combination of nivolumab and ipilimumab with two cycles of chemotherapy significantly improved overall survival compared to chemotherapy alone, with a median survival of 15.6 months versus 10.9 months.

The treatment regimen showed a favorable safety profile, with serious treatment-related adverse events occurring in 30% of the experimental group compared to 18% in the control group, indicating that the benefits of the combination therapy outweigh the risks.

The combination of activated Notch signaling, loss of p53, and the IDH1R132C mutation in mice led to the development of intrahepatic cholangiocarcinoma (ICC), demonstrating a clear oncogenic potential of the IDH1R132C mutation.

In contrast, other combinations of these factors did not result in tumor formation, indicating that the specific interaction of NICD, shP53, and IDH1R132C is crucial for ICC development, which was confirmed by the presence of histological features similar to human ICCs.

Wild-type IDH2 is up-regulated in lung cancer and is associated with poor survival outcomes, indicating its potential role as a biomarker for cancer prognosis.

Targeting IDH2 with specific inhibitors or shRNA reduces HIF1α expression, leading to decreased lung cancer cell proliferation and tumor growth, suggesting that IDH2 could be a promising therapeutic target in lung cancer treatment.

In a study involving 3697 patients with advanced hepatocellular carcinoma (HCC), immune checkpoint inhibitors (ICIs) demonstrated a median overall survival of 12.0 months and a median progression-free survival of 4.9 months, indicating their efficacy in treating this cancer.

Combining ICIs with anti-vascular endothelial growth factor (VEGF) agents resulted in improved survival outcomes, with a median overall survival of 16.4 months, while maintaining a manageable safety profile, as only 28% experienced grade 3 or higher adverse events.

The study identified the IDH2 rs11540478 genetic variant as a new risk factor for lung cancer, showing that carriers of the TT and CT genotypes have a 44% higher risk compared to CC carriers, based on an analysis of 262 lung cancer patients and 602 healthy controls.

Functional analysis revealed that the T allele of rs11540478 is associated with increased IDH2 expression and higher lung cancer cell viability, suggesting that this genetic variant may play a significant role in the development of lung cancer.

Immune checkpoint inhibitors (ICPI) significantly improve overall survival across various solid cancers, with a hazard ratio of 0.74, indicating a 26% reduction in the risk of death compared to standard treatments.

While ICPIs are generally well tolerated and show better side effect profiles than traditional chemotherapy, the use of PD-L1 expression as a biomarker for directing ICPI therapy is questionable, suggesting the need for further research into alternative biomarkers.
