What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how Camu Camu, a type of berry, might enhance the effectiveness of immune checkpoint inhibitors (ICI), which treat advanced cancers such as non-small cell lung cancer (NSCLC) and melanoma. The researchers aim to determine if adding Camu Camu can safely boost the body's immune response to these cancers. Participants should have advanced NSCLC or melanoma and be receiving or about to receive ICI treatment. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative approach.

Do I have to stop taking my current medications for the trial?

The trial requires you to stop taking probiotics and prebiotics at least 2 weeks before starting, and you cannot take them during the trial. Antibiotics should also be stopped 2 weeks before, but if needed during the trial, you can continue. Other medications are not specifically mentioned, so check with the trial team.

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

Research has shown that Camu Camu, when combined with immune checkpoint inhibitors, is safe for patients with melanoma and non-small cell lung cancer (NSCLC). Patients generally tolerate it well, with few side effects reported. Studies involving many patients, including those with NSCLC and melanoma, have confirmed its safety.

Immune checkpoint inhibitors are known to improve survival rates in NSCLC and typically cause fewer side effects than traditional chemotherapy. While some side effects can occur, they are usually less severe. Current research indicates that both treatments are well-tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about using Camu Camu in combination with immune checkpoint inhibitors (ICIs) for treating non-small cell lung cancer (NSCLC) because it introduces a natural, plant-derived component into the treatment mix. Camu Camu is packed with antioxidants which might enhance the immune system's ability to fight cancer, potentially boosting the effectiveness of existing ICIs like pembrolizumab and nivolumab. Unlike current standard treatments that rely solely on drugs, this approach leverages a nutritional supplement, offering a novel way to potentially improve patient outcomes.

What evidence suggests that Camu Camu Capsules might be an effective treatment for non-small cell lung cancer?

Research has shown that Camu Camu (CC), a type of berry, might enhance the effectiveness of immune checkpoint inhibitors (ICIs) in treating non-small cell lung cancer (NSCLC). Early findings suggest that CC can increase levels of a beneficial gut bacterium called Akkermansia muciniphila, which is linked to improved ICI performance. In initial studies, adding CC to the treatment plan reduced tumor size more effectively. In this trial, participants will receive a combination of CC with ICIs such as nivolumab and pembrolizumab, which have already helped NSCLC patients live longer. Combining CC with ICIs might further improve these outcomes. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Camu Camu Capsules
• Immune Checkpoint Inhibitors

Trial Overview The study tests the safety and tolerability of Camu Camu (CC) prebiotic capsules in combination with standard ICIs in treating NSCLC and melanoma. CC may enrich beneficial gut bacteria linked to better ICI response. Patients are grouped based on their disease stage and treatment regimen.

How Is the Trial Designed?

Group I: Camu-camu (intervention) in addition to standard-of-care ICI Experimental Treatment 1 Intervention

Camu-camu (intervention) will be added to standard-of-care ICI in: Cohort 1. For patients with advanced NSCLC, treatment will consist of single-agent pembrolizumab in combination with physician's choice platinum-doublet chemotherapy in combination with CC. Cohort 2. For patients with advanced cutaneous melanoma, treatment will consist of single-agent anti-PD-1 either nivolumab or pembrolizumab at the discretion of the treating physician. Cohort 3. For patients with advanced melanoma receiving standard-of-care ICI (either single-agent anti-PD-1 or combination anti-CTLA-4 plus anti-PD-1) who experience progressive disease (PD), their current regimen will continue unchanged and they will receive CC at 1500 mg for 3 months or until confirmed progression if progression occurs earlier.

Published Research Related to This Trial

Immunotherapy targeting PD-1/PD-L1 and CTLA-4 has shown increased survival benefits in treating metastatic non-small cell lung cancer (NSCLC), but it is also associated with significant cardiotoxicity, particularly high-grade conduction disorders like 3rd degree heart block.

A case study highlighted a patient who developed 3rd degree heart block 16 days after starting combination therapy with ipilimumab and nivolumab, emphasizing that over 75% of immunotherapy-related cardiotoxicity cases occur within the first 6 weeks, which underscores the need for early identification and monitoring of high-risk patients.
