Trial Summary

What is the purpose of this trial?

This trial tests a special vaccine made from the patient's own cells and a virus, combined with a drug that boosts the immune system, in patients with advanced lung cancer who have already tried other treatments. The vaccine helps the immune system recognize cancer, and the drug helps the immune system attack it.

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, but you cannot use systemic corticosteroids within 10 days of starting the treatment. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug pembrolizumab for lung cancer?

Pembrolizumab has been approved by the FDA for treating metastatic non-small cell lung cancer (mNSCLC) with high PD-L1 expression, showing significant improvements in survival compared to chemotherapy in clinical trials.12345

Is the combination of Dendritic Cell Vaccine and Pembrolizumab safe for humans?

Pembrolizumab (also known as Keytruda or MK-3475) has been studied in various cancers and is generally considered safe, but it can cause side effects like fatigue, cough, nausea, and immune-related issues such as inflammation of the lungs, liver, or thyroid. In nonhuman primate studies, pembrolizumab showed no significant toxic effects, supporting its safety profile in humans.12678

What makes the dendritic cell vaccine and pembrolizumab treatment unique for lung cancer?

This treatment combines a dendritic cell vaccine, which helps the immune system recognize and attack cancer cells, with pembrolizumab, a drug that blocks a protein called PD-1 to boost the immune response against cancer. This combination aims to enhance the body's ability to fight lung cancer more effectively than using pembrolizumab alone.12356

Treatment Details

Interventions

  • Autologous Dendritic Cell-Adenovirus CCL21 Vaccine
  • Pembrolizumab
Trial OverviewThe trial tests a combination of a CCL21-gene modified dendritic cell vaccine with pembrolizumab, an antibody treatment. The vaccine aims to help the immune system attack cancer cells while pembrolizumab may stop tumor growth by blocking certain proteins.

Experimental Treatment
Group I: Treatment (Ad-CCL21-DC vaccine, pembrolizumab)Experimental Treatment2 Interventions
Patients receive pembrolizumab IV over 30 minutes followed by autologous dendritic cell-adenovirus CCL21 vaccine by CT-guided or bronchoscopic IT injection on days 0, 21, and 42. Patients then receive pembrolizumab every 3 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity.

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 for the treatment of thoracic malignancies: current landscape and future directions.Karim, S., Leighl, N.[2017]
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.

In a Phase 2 study involving 35 patients with non-small cell lung cancer, neoadjuvant pembrolizumab was found to be safe and well tolerated, with only one surgery delay due to thyroiditis and no mortality within 90 days post-surgery.
The study showed a high rate of R0 resection (88%) and a major pathologic response in 28% of patients, indicating that pembrolizumab may be more effective than standard neoadjuvant chemotherapy in this setting.
