IFx-Hu2.0 + Pembrolizumab for Skin Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new treatment for individuals with advanced or metastatic Merkel Cell Carcinoma, a type of skin cancer. Researchers aim to determine if adding IFx-Hu2.0, an experimental treatment, to pembrolizumab can enhance the cancer's response to treatment. Participants will receive either the new combination treatment or a placebo (a harmless, inactive substance) alongside pembrolizumab to compare results. This trial may suit those with unresectable or metastatic Merkel Cell Carcinoma who have not previously received certain immune therapies. As a Phase 2, Phase 3 trial, it evaluates the treatment's effectiveness in a smaller group and represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking cancer therapy.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on systemic corticosteroids or other immunosuppressive medications, you may need to stop them at least 14 days before starting the trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that IFx-Hu2.0 is generally safe for humans. In earlier studies, patients tolerated this treatment well, meaning it didn't cause major problems. For example, one study found that weekly doses of IFx-Hu2.0 for three weeks were manageable without major issues. Some patients experienced minor side effects, but serious problems were rare. This suggests that IFx-Hu2.0 can be safely combined with other treatments.
The FDA has already approved pembrolizumab for treating some cancers, indicating its safety has been thoroughly tested. However, like many treatments, pembrolizumab can cause side effects, such as tiredness and skin reactions.
Overall, past studies have shown that both IFx-Hu2.0 and pembrolizumab are generally well-tolerated.12345Why do researchers think this study treatment might be promising for skin cancer?
Researchers are excited about IFx-Hu2.0 for skin cancer because it introduces a novel approach by combining a targeted intralesional injection with existing immunotherapy. Unlike standard treatments like surgery, radiation, or topical medications, IFx-Hu2.0 is directly injected into the tumor, which might enhance its effectiveness by concentrating the treatment right where it's needed. This method is paired with pembrolizumab, an established immunotherapy, to potentially boost the immune response against the cancer. The unique delivery method and combination with immunotherapy offer hope for improved outcomes in skin cancer treatment.
What evidence suggests that IFx-Hu2.0 might be an effective treatment for skin cancer?
Studies have shown promising results for IFx-Hu2.0 in treating Merkel Cell Carcinoma (MCC), a type of skin cancer. One study found that 56% of MCC patients responded well to IFx-Hu2.0 before receiving additional immune system treatments. Another study reported a 71% response rate when a PD-L1 inhibitor, a specific immune therapy, followed IFx-Hu2.0 treatment. This trial will evaluate IFx-Hu2.0 in combination with Pembrolizumab, a PD-1 inhibitor, to determine if it enhances the effectiveness of immune therapies for people with advanced skin cancer like MCC. These findings offer hope that IFx-Hu2.0 may help the body's immune system fight cancer more effectively.12367

Are You a Good Fit for This Trial?
Adults with advanced or metastatic Merkel Cell Carcinoma who haven't been treated with checkpoint inhibitors like Pembrolizumab. They should have a life expectancy of at least six months, an ECOG status ≤2, measurable disease by RECIST v1.1 criteria, and proper organ function.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- IFx-Hu2.0
Trial Overview
The trial is testing IFx-Hu2.0 as an add-on to Pembrolizumab versus a placebo followed by Pembrolizumab in treating Merkel Cell Carcinoma. Participants are randomly assigned to receive either the real drug or placebo through injection into one tumor lesion.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Placebo Group
Participants randomized to the treatment arm will receive IFx-Hu2.0 (0.1 mg) via intralesional injection in a single lesion once per week for 3 consecutive weeks. Pembrolizumab (200 mg) will be administered intravenously (IV) on Day 1, followed by administration every 3 weeks during the first year of treatment. In the second year, the pembrolizumab dose will be 400 mg every 6 weeks. Pembrolizumab treatment will continue until progressive disease (PD), unacceptable immune-related toxicities, or for a maximum duration of 2 years.
Participants randomized to the control arm will receive placebo (0.9% Sodium Chloride Injection, USP) via intralesional injection in a single lesion once per week for 3 consecutive weeks. Pembrolizumab (200 mg) will be administered IV on Day 1, followed by administration every 3 weeks during the first year of treatment. In the second year, the dose will be 400 mg every 6 weeks. Pembrolizumab treatment will continue until PD, unacceptable immune-related toxicities, or for a maximum duration of 2 years.
