What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores the effects of a new antibody treatment, GEN1055, on certain cancers. Researchers aim to understand how GEN1055 works alone and in combination with another cancer drug, pembrolizumab (KEYTRUDA), and possibly chemotherapy. The trial seeks to determine the best doses and assess how well these combinations combat cancer. It is recruiting participants with advanced or metastatic solid tumors who have not responded to standard treatments. Participants will receive active treatment for up to 24 months, with regular site visits to monitor safety and effectiveness. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot have had certain cancer treatments within 4 weeks or certain systemic therapies within 5 half-lives of the drug before starting the trial. It's best to discuss your current medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Previous studies have found GEN1055 to be safe when used alone. About 33% of patients experienced moderate side effects, and no treatment-related deaths occurred, suggesting the treatment is generally well-tolerated.

When combined with pembrolizumab, the safety outlook remains positive. Pembrolizumab, already approved for treating certain cancers, is known for not causing severe side effects that could affect surgery outcomes. So far, combining these two treatments has not revealed any unexpected safety issues.

The trial is in its early stages, focusing primarily on safety and determining the right doses. While some safety information is still being collected, current data suggests the treatment's side effects are manageable. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about GEN1055 in combination with pembrolizumab for cancer because it represents a novel approach to treatment. While most cancer therapies focus on directly attacking cancer cells, GEN1055 is designed to boost the body's immune response, potentially enhancing the effectiveness of pembrolizumab, an established immunotherapy. By combining GEN1055 with pembrolizumab, there is hope to improve patient outcomes by making cancer cells more visible to the immune system. Additionally, this combination might offer a new option for patients who have not responded well to existing treatments like chemotherapy and other standard immunotherapies.

What evidence suggests that this trial's treatments could be effective for cancer?

Research shows that pembrolizumab, an antibody used in this trial, effectively treats various cancers. It is approved for conditions such as non-small cell lung cancer and melanoma. Studies indicate that pembrolizumab, particularly when combined with chemotherapy, can significantly improve survival rates. In this trial, some participants will receive pembrolizumab with GEN1055, while others may receive GEN1055 alone or with both pembrolizumab and standard chemotherapy. GEN1055 is newer and has less data available, but it is being tested for safety and effectiveness as a promising cancer-fighting antibody. Researchers are studying the combination of GEN1055 and pembrolizumab to determine if they work better together. Early results are promising, but more research is needed to fully understand their benefits. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults with certain advanced solid tumors that have worsened after standard treatments or when no other treatment is likely to help. They should be relatively healthy otherwise, able to perform daily activities with ease (ECOG PS score of 0-1), and have measurable disease according to specific criteria.

Inclusion Criteria

I can provide scans showing my cancer's progress after the last treatment failed.

I am fully active or restricted in physically strenuous activity but can do light work.

My cancer can be measured by scans.

What Are the Treatments Tested in This Trial?

Interventions

• GEN1055
• Pembrolizumab
• Standard Chemotherapy

Trial Overview

The study tests the antibody GEN1055 alone and in combination with pembrolizumab, with or without standard chemotherapy. The first part determines safe doses; the second part evaluates how well these doses work against cancer. Treatment can last up to 24 months unless stopped earlier due to progression or side effects.

How Is the Trial Designed?

Group I: Expansion Experimental Treatment 3 Interventions

GEN1055 will be administered as monotherapy or in combination with pembrolizumab or in combination with pembrolizumab and standard chemotherapy in separate expansion cohorts, at a dose level selected from the Dose Escalation part.

Group II: Dose Escalation Experimental Treatment 2 Interventions

GEN1055 will be administered as monotherapy and in combination with a fixed dose of pembrolizumab.

Published Research Related to This Trial

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.
