What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if adding durvalumab (an immunotherapy) to a combination of chemotherapy and radiation is safe and effective for people with esophageal cancer. The researchers seek to understand how this combination impacts the cancer and the patients, both positively and negatively. It targets individuals with esophageal or gastroesophageal junction adenocarcinoma who have not previously undergone chemotherapy. Participants should have cancer confined to the esophagus or nearby areas and must be eligible for surgical removal. As a Phase 1, Phase 2 trial, this research focuses on understanding how the treatment works in people and measuring its effectiveness in an initial, smaller group, offering participants the opportunity to contribute to groundbreaking cancer treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot use immunosuppressive medications within 28 days before starting the trial, except for certain types like low-dose corticosteroids or local steroid injections.

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

Research has shown that combining durvalumab and tremelimumab with chemotherapy is generally safe. In patients with advanced esophageal cancer, this treatment was mostly well-tolerated. Some studies found that patients experienced side effects, but these were usually manageable. Common side effects included tiredness and nausea, which are typical with cancer treatments.

Durvalumab is already approved for other cancers, indicating its safety in those cases. However, the combination with tremelimumab is still under study, so less safety information is available. As this trial is in the early stages, researchers are primarily focused on understanding the safety and potential side effects of this drug combination. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about combining immunotherapy with chemoradiation for esophageal cancer because it introduces a unique approach to treatment. Unlike the standard regimen of chemotherapy and radiation, this combination includes durvalumab and tremelimumab, which are monoclonal antibodies targeting specific proteins that help cancer cells evade the immune system. By blocking these proteins, the treatment aims to enhance the body's immune response against the cancer. This novel mechanism could potentially improve outcomes by making the cancer more susceptible to the effects of traditional chemoradiation, offering hope for better effectiveness compared to standard therapies.

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

This trial will evaluate the combination of durvalumab and tremelimumab with chemoradiation for treating esophageal and gastroesophageal junction adenocarcinoma. Research has shown that using durvalumab and tremelimumab with chemoradiation may be promising for this condition. Studies have found that this combination can address safety concerns and help shrink or control the cancer. These two drugs are a type of immunotherapy, which helps the immune system recognize and attack cancer cells. While these results are encouraging, more research is needed to confirm their effectiveness in this specific situation. ^{1 2 4 5 6}

Preoperative treatment with pembrolizumab combined with chemoradiotherapy was found to be safe for 20 patients with resectable esophageal squamous cell carcinoma, with a high pathologic complete response (pCR) rate of 55.6%.

Despite some patients experiencing significant adverse events, including grade III lymphopenia in 65% of cases, the treatment did not delay surgery, indicating its feasibility for clinical use.

In a safety run-in phase of the DURIGAST PRODIGE 59 study involving 11 patients with advanced gastric or gastro-oesophageal junction adenocarcinoma, 63.6% experienced significant adverse events, primarily neutropenia, indicating a notable safety concern with the treatment combination.

The combination of FOLFIRI with Durvalumab and/or Tremelimumab showed an expected safety profile, allowing progression to the randomized phase II study, although careful monitoring for serious adverse events is necessary.

Pre-operative chemotherapy with Paclitaxel-Carboplatin followed by adjuvant immunotherapy using Nivolumab has significantly improved the management of locally advanced esophageal cancer, which historically has a poor prognosis.

Current trials are exploring the effectiveness of immunotherapy for non-operable esophageal cancers, while strategies like dose escalation and combining pre-operative chemo-radiotherapy with trastuzumab have not shown benefits.

The ARION trial is investigating the efficacy of the anti-PD-L1 drug durvalumab combined with standard chemoradiotherapy (CRT) in patients with locally advanced unresectable esophageal cancer, aiming to improve progression-free survival from 50% to 68% at 12 months.

This multicenter phase II trial will also explore potential biomarkers, such as PD-L1 expression and gut microbiota, to better understand the immune response and treatment outcomes, highlighting the importance of combining immunotherapy with traditional treatments.

A patient with advanced esophageal squamous cell carcinoma (ESCC) showed a significant response to the combination of durvalumab and tremelimumab for over 6 months, despite the primary esophageal tumor being resistant.

The study found that the esophageal tumor had a unique immune profile with higher levels of regulatory T cells and neutrophils, suggesting that these immune characteristics may influence the varied responses to immune checkpoint inhibitors in different tumor sites.

In a study of 107 patients with stage III non-small cell lung cancer (NSCLC) treated with concurrent chemoradiotherapy (CCRT) and intensity-modulated radiotherapy (IMRT), the median progression-free survival (PFS) was 20.7 months, indicating effective treatment outcomes.

Factors associated with longer PFS included a favorable response to CCRT, a radiation dose of 62 Gy or more, and having stage IIIA NSCLC, while shorter durations of durvalumab treatment and lower radiation doses were linked to increased mortality risk.

In a phase II study involving 86 patients with esophageal squamous cell carcinoma, adjuvant durvalumab did not show a significant improvement in disease-free survival or overall survival compared to placebo after neoadjuvant chemoradiotherapy.

However, in patients with positive PD-L1 expression, durvalumab was associated with a higher overall survival rate, suggesting that PD-L1 status may help predict the effectiveness of durvalumab in this treatment context.

In the CASPIAN study involving 805 patients with extensive-stage small-cell lung cancer (ES-SCLC), the combination of durvalumab and platinum-etoposide significantly improved overall survival compared to platinum-etoposide alone, with a median survival of 12.9 months versus 10.5 months.

However, adding tremelimumab to durvalumab and platinum-etoposide did not provide a significant survival benefit, indicating that durvalumab plus platinum-etoposide should be considered the new standard of care for first-line treatment of ES-SCLC.

In a phase Ib study involving 136 patients, durvalumab (Du) combined with tremelimumab (Tr) and standard platinum-doublet chemotherapy was found to be safe, with most drug-related adverse events being mild (≤ grade 2) and primarily due to chemotherapy.

Among 73 patients with non-small cell lung cancer (NSCLC), the treatment achieved a 51% objective response rate, with a median progression-free survival of 6.5 months and overall survival of 19.8 months, indicating promising efficacy comparable to other immunotherapy and chemotherapy combinations.

In a study of 45 patients with esophageal squamous cell carcinoma, simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) demonstrated promising overall survival rates of 42.2% and progression-free survival rates of 40.7% at 3 years, indicating its efficacy as a treatment option.

The treatment was associated with a low toxicity profile, as no patients experienced severe (grade 4-5) side effects, and the most common side effect, radiation esophagitis, was manageable, affecting 64% of patients but only 13% at grade 3 severity.

The combination therapy demonstrated a higher objective response rate (ORR) of 10.8% in BTC and 20.3% in esophageal squamous cell carcinoma (ESCC), indicating potential clinical benefit for patients with advanced cancers who had disease progression after prior treatments.
