IFx-Hu2.0 + Pembrolizumab for Merkel Cell Carcinoma
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new combination of treatments for Merkel Cell Carcinoma, a rare and aggressive skin cancer. It aims to determine if adding IFx-Hu2.0, an experimental treatment, to pembrolizumab, a type of immunotherapy, is safe and feasible for patients with advanced stages of this cancer. Participants will receive injections directly into a tumor, followed by pembrolizumab infusions. This trial may suit individuals with advanced Merkel Cell Carcinoma that cannot be surgically removed and who have not previously received checkpoint inhibitors like pembrolizumab. 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.
Do I have to stop taking my current medications for the trial?
The trial does not specify if you need to stop taking your current medications. However, if you are on systemic corticosteroids or other immunosuppressive medications, you must stop them at least 14 days before starting the trial treatment.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study found IFx-Hu2.0 to be safe for patients, with no serious side effects reported. About 33% of patients experienced mild side effects, such as redness or swelling, suggesting that IFx-Hu2.0 is generally well-tolerated when used alone.
Pembrolizumab has also proven safe for most people. Another study reported rare cases of immune-related lung issues, but most patients did not experience severe side effects. Pembrolizumab is already approved for treating Merkel cell carcinoma (a type of skin cancer) and has been used safely by many patients.
Overall, past research indicates that both treatments are safe for patients.12345Why do researchers think this study treatment might be promising?
Most treatments for Merkel Cell Carcinoma focus on using immune checkpoint inhibitors like pembrolizumab to help the immune system attack cancer cells. But the new treatment, IFx-Hu2.0, works differently by being directly injected into the tumor, which may enhance the immune response precisely where it's needed. This localized approach could potentially improve effectiveness while minimizing systemic side effects. Researchers are excited about the possibility that combining IFx-Hu2.0 with pembrolizumab could lead to more robust and targeted immune responses, offering new hope for patients with this aggressive skin cancer.
What evidence suggests that IFx-Hu2.0 and pembrolizumab could be effective for Merkel Cell Carcinoma?
Research has shown that pembrolizumab effectively treats various cancers, including Merkel cell carcinoma, by helping the immune system target and combat cancer cells more effectively. In this trial, participants will receive a combination of IFx-Hu2.0 and pembrolizumab. Early studies of IFx-Hu2.0 with pembrolizumab have shown promise in enhancing the immune response to cancer cells. This combination aims to overcome resistance to standard treatments and improve patient outcomes. Initial findings suggest that adding IFx-Hu2.0 may enhance pembrolizumab's effectiveness by promoting a stronger attack on tumors.23567

Are You a Good Fit for This Trial?
Adults with advanced or metastatic Merkel Cell Carcinoma (MCC) who haven't been treated with CPI drugs like Pembrolizumab before. They should have a life expectancy of at least six months, be able to perform daily activities (ECOG ≤ 2), and have measurable disease by scans. Their cancer must be stage III/IV and they need at least one lesion suitable for injection.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- IFx-Hu2.0
- Pembrolizumab
Trial Overview
The trial is testing IFx-Hu2.0 as an additional treatment alongside Pembrolizumab in patients with MCC. Nine participants will receive an injection of IFx-Hu2.0 directly into a tumor lesion followed by standard treatment with Pembrolizumab.

Experimental Treatment
Subjects will receive IFx-Hu2.0 (0.1 mg) as a visceral lesion injection in a single lesion once per week for three consecutive weeks. KEYTRUDA® (pembrolizumab) (200 mg) will be administered intravenously (IV) on Visit 1 (within 48 hours from the first IFx-Hu2.0 injection) then every three weeks for approximately six months, until disease progression or unacceptable immune related toxicity.
