What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether a combination of two drugs, atezolizumab (Tecentriq) and tiragolumab, can effectively treat squamous cell carcinoma, a type of head and neck cancer. The focus is on cancers that have returned or spread and show a protein marker called PD-L1. Participants will receive either both drugs or one drug with a placebo (a substance with no active treatment). Suitable candidates have this specific cancer type and have not received prior treatment for cancer that has spread or returned. As a Phase 2 trial, the research measures how well the treatment works in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it excludes those on systemic immunostimulatory or immunosuppressive medications. It's best to discuss your specific medications with the trial team.

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

Research has shown that the combination of atezolizumab and tiragolumab is generally well-tolerated. Studies found no unexpected safety issues when patients used these two drugs together. Earlier research described the combination as tolerable, with most side effects being manageable. There were no major differences in drug metabolism, indicating that tiragolumab does not compromise the safety of atezolizumab. Overall, these findings suggest the treatment is relatively safe, though patients should remain aware of possible side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about atezolizumab combined with tiragolumab for head and neck cancer because it introduces a novel approach to immune system activation. Unlike traditional treatments like chemotherapy and radiation, which attack cancer cells directly, this combination works by enhancing the body's immune response. Atezolizumab blocks a protein that prevents the immune system from attacking cancer cells, while tiragolumab targets another checkpoint to further boost immune activity. This dual action has the potential to more effectively identify and destroy cancer cells, offering hope for improved outcomes in patients.

What evidence suggests that this trial's treatments could be effective for head and neck cancer?

Research shows that combining atezolizumab and tiragolumab holds promise for treating squamous cell carcinoma of the head and neck (SCCHN). In this trial, one group of participants will receive this combination. Previous studies demonstrated that this combination improved the cancer's response to treatment, achieving a response rate of 37% compared to 21% with atezolizumab alone. Additionally, patients experienced a longer period without cancer progression, lasting 5.6 months compared to 3.9 months with only atezolizumab. These findings suggest that adding tiragolumab to atezolizumab may enhance treatment effectiveness for this type of cancer. ^{3 6 7 8 9}

• Placebo
• Tiragolumab

Trial Overview

The study tests how well Atezolizumab combined with Tiragolumab works compared to Atezolizumab with a placebo in treating this type of cancer as a first-line treatment. It measures the rate at which tumors respond to these treatments and also looks into safety and how the body processes these drugs.

How Is the Trial Designed?

Group I: Atezolizumab + Tiragolumab Experimental Treatment 2 Interventions

Participants will receive atezolizumab followed by tiragolumab every three weeks (Q3W) on Day 1 of each 21-day cycle.

Group II: Atezolizumab + Placebo Placebo Group 2 Interventions

Participants will receive atezolizumab followed by placebo Q3W on Day 1 of each 21-day cycle.

Published Research Related to This Trial

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.

Atezolizumab, an anti-PD-L1 antibody used for treating advanced cancers like metastatic non-small cell lung cancer, has a low incidence of cutaneous side effects, with only 20% of patients experiencing mild rashes that did not require treatment.

There have been no reported cases of severe skin reactions such as Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) associated with atezolizumab, suggesting a favorable safety profile for dermatological side effects.

In a study involving 133 patients with locally advanced squamous cell carcinoma of the head and neck, pembrolizumab combined with radiotherapy did not show a significant improvement in locoregional control or survival compared to the standard treatment of cetuximab with radiotherapy.

However, patients receiving pembrolizumab experienced significantly lower toxicity, with only 74% reporting severe adverse events compared to 92% in the cetuximab group, suggesting it may be a safer option for patients unfit for high-dose cisplatin.
