Trial Summary

What is the purpose of this trial?

The goal of this trial is to learn about the antibody GEN1055 when it is used alone and when it is used together with another antibody cancer drug, pembrolizumab (with or without chemotherapy), for treatment of participants with certain types of cancer. Participants will receive either GEN1055 alone, GEN1055 with pembrolizumab, or GEN1055 with pembrolizumab and chemotherapy. All participants will receive active drug; no one will receive placebo. This trial has 2 parts. The purpose of the first part is to find out if GEN1055 is safe and to find out the doses of GEN1055 to use alone and to use with pembrolizumab. The purpose of the second part is to give GEN1055 to more participants to see how well the doses of GEN1055 that were selected in the first part work against cancer alone and how well they work with pembrolizumab (with or without other chemotherapy). A participant will receive trial treatment up to a maximum of 24 months for pembrolizumab-containing regimens, or until: * the cancer progresses. * there are side effects requiring that treatment be stopped. * the participant decides to not participate further in this trial. * the doctor believes it is in the participant's best interest to stop treatment. Participation in the trial will require visits to the site. For the first 12 weeks there will be weekly visits and after that, visits will be every 3 weeks. At site visits, there will be various tests (such as blood draws) and procedures (such as recording of heart activity, computed tomography (CT) scans) to monitor whether the treatment is safe and effective. The trial duration (including screening, treatment, and follow-up) for each participant will be about 39 months.

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.

What data supports the effectiveness of the drug pembrolizumab in treating cancer?

Pembrolizumab has shown effectiveness in treating various cancers, including non-small cell lung cancer and melanoma. It has been approved by the FDA for improving survival rates in patients with these cancers, demonstrating significant benefits over standard chemotherapy. ^{1 2 3 4 5}

What safety data exists for Pembrolizumab (Keytruda) in cancer treatment?

Pembrolizumab (Keytruda) has been associated with some side effects, including fatigue, cough, nausea, skin rash, and diarrhea. More serious immune-related side effects can occur, such as lung inflammation (pneumonitis), inflammation of the colon (colitis), liver inflammation (hepatitis), and thyroid problems. Rarely, it can cause type 1 diabetes. ^{1 2 5 6 7}

What makes the drug combination GEN1055 and Pembrolizumab unique for cancer treatment?

The combination of GEN1055 and Pembrolizumab is unique because it involves using Pembrolizumab, a PD-1 inhibitor that helps the immune system attack cancer cells, alongside GEN1055, which may offer a novel mechanism or enhance the immune response, although specific details about GEN1055 are not provided in the available research. ^{1 2 3 5 8}

Treatment Details

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.

Participant Groups

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.

Findings from Research

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.

Pembrolizumab, a PD-1 inhibitor, has demonstrated clinical effectiveness in treating various solid tumors, particularly in patients with PD-L1-positive non-small-cell lung cancer and unresectable/metastatic melanoma.

Early-phase trials and ongoing studies are focused on further confirming the clinical benefits of pembrolizumab in thoracic malignancies, highlighting its potential as a significant treatment option in cancer therapy.

Pembrolizumab is a monoclonal antibody that effectively blocks the PD-1 receptor on T cells, enhancing their ability to attack cancer cells, particularly in melanoma patients.

In a Phase I study involving 411 patients, pembrolizumab demonstrated high durable response rates with minimal toxicity, indicating its potential as a safe and effective treatment option for melanoma.

Pembrolizumab (Keytruda) was approved by the FDA for treating metastatic non-small cell lung cancer (mNSCLC) in patients with tumors expressing PD-L1, showing significant improvements in overall survival (OS) and progression-free survival (PFS) in two major clinical trials with thousands of participants.

In the KEYNOTE-024 trial, pembrolizumab demonstrated a 40% reduction in the risk of death compared to chemotherapy, while in the KEYNOTE-010 trial, it also showed a significant survival advantage over chemotherapy in patients who had previously progressed on treatment.

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.

Pembrolizumab, an immune checkpoint inhibitor, can cause pneumonitis in 1%-5% of patients, and this case report highlights an atypical presentation of this side effect in a patient with metastatic squamous cell carcinoma.

The patient was successfully treated with steroid therapy after ruling out other potential causes, leading to complete resolution of the pneumonitis, emphasizing the importance of recognizing and managing atypical cases of checkpoint inhibitor-pneumonitis.

Pembrolizumab, a PD-1 inhibitor used in cancer treatment, can lead to rare but serious immune-related adverse events, including type 1 diabetes mellitus, occurring in about 0.2% of cases.

A review of 42 cases revealed that patients may develop diabetic ketoacidosis during treatment, highlighting the need for blood glucose monitoring and awareness of this potential side effect among clinicians.
