Trial Summary

What is the purpose of this trial?

This trial tests NTX-1088, alone or with pembrolizumab, in patients with advanced solid cancers. NTX-1088 helps the immune system find and attack cancer cells, while pembrolizumab boosts the immune system's ability to fight cancer.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot be on certain cancer treatments or immunosuppressive therapies when starting the trial.

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

Pembrolizumab has been shown to improve survival in patients with non-small cell lung cancer and is approved for use in esophageal cancer, demonstrating its effectiveness in treating certain types of cancer. ^{1 2 3 4 5}

Is the combination of NTX-1088 and Pembrolizumab safe for humans?

Pembrolizumab (also known as KEYTRUDA) has been used in various clinical trials for different cancers, showing common side effects like fatigue, cough, nausea, and rash. More serious immune-related side effects can include lung inflammation, liver inflammation, and thyroid issues. While these studies provide safety data for Pembrolizumab, specific safety data for the combination with NTX-1088 is not available. ^{1 3 4 6 7}

What makes the drug NTX-1088 + Pembrolizumab unique for cancer treatment?

The combination of NTX-1088 with Pembrolizumab is unique because it pairs a novel treatment (NTX-1088) with Pembrolizumab, a well-established immune checkpoint inhibitor that blocks the PD-1 pathway, enhancing the immune system's ability to fight cancer. This combination may offer a new approach to treating cancers that are resistant to standard therapies. ^{1 3 4 8 9}

Trial Overview The trial studies NTX-1088 alone and combined with Pembrolizumab in patients with advanced solid malignancies. It's a two-part study: first testing different doses of NTX-1088 (dose escalation) and then expanding the trial to more patients at the chosen dose.

Participant Groups

Group I: Part 2 - Dose Expansion (Monotherapy) Experimental Treatment 1 Intervention

NTX-1088 administered at the RP2D as a 60-minute IV infusion as a monotherapy.

Group II: Part 2 - Dose Expansion (Combination Therapy) Experimental Treatment 2 Interventions

NTX-1088 administered at the RP2D as a 60-minute IV infusion in combination with pembrolizumab at the standard labeled dose.

Group III: Part 1 - Dose Escalation Phase (Monotherapy) Experimental Treatment 1 Intervention

NTX-1088 administered as a 60-minute IV infusion at escalating doses as a monotherapy. NTX-1088 will be administered on Day 1 of a 21-day cycle.

Group IV: Part 1 - Dose Escalation Phase (Combination Therapy) Experimental Treatment 2 Interventions

NTX-1088 administered as a 60-minute IV infusion in escalating doses in combination with pembrolizumab. NTX-1088 will be administered on Day 1 of a 21-day cycle. Pembrolizumab will be administered as a 30-minute IV infusion, within 2 hours prior to NTX-1088 administration, at a dose of 200 mg on Day 1 of every 21-day cycle.

Findings from Research

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 (Keytruda) is an approved treatment for metastatic or locally advanced esophageal and gastroesophageal junction cancer, indicating its efficacy in targeting these specific cancer types.

It is used in combination with platinum- and fluoropyrimidine-based chemotherapy, suggesting a synergistic approach to enhance treatment effectiveness.

Pembrolizumab Approved for Esophageal or Gastroesophageal Cancer. Aschenbrenner, DS.[2023]

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.

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.
