What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it does exclude participants who are on systemic immunosuppressive medication, so you may need to discuss your specific medications with the trial team.

What safety data exists for Atezolizumab and Durvalumab in cancer treatment?

Atezolizumab and Durvalumab, both used in cancer treatments, have shown favorable safety profiles in clinical trials. However, Durvalumab has been associated with an increased risk of pneumonitis (lung inflammation), a serious side effect. It's important to discuss potential risks with your healthcare provider. ^{1 2 3 4 5}

What makes the drug combination of Atezolizumab and Tiragolumab unique for lung cancer treatment?

The combination of Atezolizumab and Tiragolumab is unique because it targets two immune checkpoints, PD-L1 and TIGIT, potentially enhancing the immune system's ability to fight non-small-cell lung cancer (NSCLC) more effectively than targeting PD-L1 alone. ^{1 2 6 7 8}

What data supports the effectiveness of the drug combination Atezolizumab and Tiragolumab for lung cancer?

Research shows that Atezolizumab, when combined with chemotherapy, has been effective in treating advanced non-small-cell lung cancer (NSCLC). Additionally, the CITYSCAPE trial suggests that combining Tiragolumab with Atezolizumab may enhance the treatment's effectiveness for NSCLC. ^{2 6 7 9 10}

• Durvalumab
• Tiragolumab

Trial Overview The study tests the effectiveness and safety of combining two drugs: Atezolizumab and Tiragolumab versus Durvalumab alone. All participants previously received platinum-based chemoradiotherapy without their cancer getting worse. The goal is to see which combination works better after this initial treatment.

How Is the Trial Designed?

Group I: Atezolizumab + Tiragolumab Experimental Treatment 2 Interventions

Participants will receive atezolizumab administered intravenously (IV) on Day 1 of each 28-day cycle followed by tiragolumab administered IV on Day 1 of each 28-day cycle for a maximum of 13 cycles.

Group II: Durvalumab Active Control 1 Intervention

Participants will receive durvalumab administered IV during each 28-day cycle for a maximum of 13 cycles.

Published Research Related to This Trial

Atezolizumab combined with chemotherapy showed promising efficacy in treating advanced, treatment-naïve non-small-cell lung cancer (NSCLC), with overall response rates of 36% to 68% across different chemotherapy regimens in a study of 76 patients.

The treatment was generally well tolerated, although common severe side effects included neutropenia and anemia, indicating a manageable safety profile for this combination therapy.

Atezolizumab is an FDA-approved treatment for advanced bladder cancer that works by blocking the PD-L1/PD-1 immune checkpoint, enhancing T-cell immunity against tumors.

In clinical trials, atezolizumab showed a 15% objective response rate in patients whose cancer progressed after chemotherapy, and a 24% response rate in chemotherapy-naïve patients, with a favorable safety profile compared to other second-line treatments.

Durvalumab, an immunotherapy drug for non-small cell lung cancer (NSCLC), has shown significant activity and acceptable tolerability, especially in patients with at least 25% PD-L1 tumor expression, and has been established as a standard treatment following chemoradiation based on the PACIFIC study results.

While durvalumab is effective in wild-type EGFR and ALK patients, its efficacy is lower in those with EGFR mutations or ALK-positive status, highlighting the need for ongoing research into combination therapies and the management of treatment-related toxicity.

In the CITYSCAPE trial involving 275 patients with chemotherapy-naive, PD-L1-positive non-small-cell lung cancer, the combination of tiragolumab and atezolizumab resulted in a significantly higher objective response rate (31.3% vs. 16.2%) and improved median progression-free survival (5.4 months vs. 3.6 months) compared to placebo plus atezolizumab.

The safety profile of tiragolumab plus atezolizumab was generally similar to that of atezolizumab alone, with serious treatment-related adverse events occurring in 21% of patients in the combination group, indicating that this combination therapy is well tolerated.

Durvalumab, a PD-L1 inhibitor, has been shown to be safe for patients with various solid tumors, with common side effects including pruritus and fatigue, based on a meta-analysis of 17 studies involving 1,529 patients.

Higher levels of PD-L1 expression in tumors are linked to better treatment responses to durvalumab, indicating that PD-L1 could serve as a useful biomarker for predicting the drug's efficacy.

Immunotherapy is becoming a key part of first-line treatment for non-small cell lung cancer (NSCLC), with various phase 3 studies showing the effectiveness of drugs targeting PD-1, PD-L1, and CTLA-4, often in combination with chemotherapy.

Patients with high PD-L1 expression (≥ 50%) can be treated with single-agent Pembrolizumab or Atezolizumab, while those with lower expression have multiple treatment options, including combinations of immunotherapy and chemotherapy, highlighting the tailored approach based on tumor characteristics.
