What You Need to Know Before You Apply

What is the purpose of this trial?

This study will evaluate the efficacy of tiragolumab plus atezolizumab and carboplatin and etoposide (CE) compared with placebo plus atezolizumab and CE in participants with chemotherapy-naive extensive-stage small cell lung cancer (ES-SCLC). Eligible participants will be stratified by Eastern Cooperative Oncology Group (ECOG) Performance Status (0 vs. 1), LDH (\</= upper limit of normal \[ULN\] vs. \> ULN), and presence or history of brain metastasis (yes vs. no) and randomly assigned in a 1:1 ratio to receive one of the following treatment regimens during induction phase:* Arm A: Tiragolumab plus atezolizumab plus CE* Arm B: Placebo plus atezolizumab plus CEFollowing the induction phase, participants will continue maintenance therapy with either atezolizumab plus tiragolumab (Arm A) or atezolizumab plus placebo (Arm B).

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, you cannot have had any prior systemic treatment for small cell lung cancer or certain investigational or immunostimulatory agents recently. It's best to discuss your current medications with the trial team.

Is the combination of Atezolizumab, Carboplatin, and Etoposide safe for treating small cell lung cancer?

The combination of Atezolizumab, Carboplatin, and Etoposide for small cell lung cancer is generally well tolerated, with no new safety concerns beyond those known for each drug individually. Common side effects include blood-related issues, skin rash, and low thyroid function, but it does not negatively affect patients' quality of life.12345

What makes the drug combination of Atezolizumab, Carboplatin, Etoposide, and Tiragolumab unique for treating small cell lung cancer?

This treatment is unique because it combines atezolizumab, an immune checkpoint inhibitor that helps the immune system attack cancer cells, with traditional chemotherapy drugs carboplatin and etoposide, and adds tiragolumab, which may further enhance the immune response. This combination aims to improve survival outcomes in patients with extensive-stage small cell lung cancer.12567

What data supports the effectiveness of the drug combination Atezolizumab, Tecentriq, Carboplatin, Paraplatin, Carboplatinum, Etoposide, Eposin, VP-16, Vepesid, Tiragolumab for treating small cell lung cancer?

Research shows that adding atezolizumab to chemotherapy significantly improves survival in patients with extensive-stage small cell lung cancer compared to chemotherapy alone, making it a valuable first-line treatment option.15689

Are You a Good Fit for This Trial?

This trial is for adults with untreated extensive-stage small cell lung cancer (ES-SCLC). Participants should have no prior treatments, good organ function, and an ECOG Performance Status of 0 or 1. They can't join if they have autoimmune diseases, active CNS metastases, previous immune therapy use, recent immunostimulatory agents use, other cancers within the last 5 years (except those with low risk), HIV/Hepatitis B/C infections, severe infections at randomization time or a history of certain lung conditions.

Inclusion Criteria

What Are the Treatments Tested in This Trial?

Interventions

  • Atezolizumab
  • Carboplatin
  • Etoposide
  • Tiragolumab
Trial Overview The study tests whether adding Tiragolumab to Atezolizumab plus chemotherapy (Carboplatin and Etoposide) improves outcomes compared to using a placebo with Atezolizumab and the same chemo in ES-SCLC patients. After initial treatment phase ('induction'), participants continue maintenance therapy either with both drugs or one drug plus placebo.

Published Research Related to This Trial

In the phase III SKYSCRAPER-02 study involving 490 patients with untreated extensive-stage small-cell lung cancer, the addition of tiragolumab to atezolizumab and chemotherapy did not significantly improve progression-free survival (PFS) or overall survival (OS).
The combination treatment was well tolerated, with similar rates of immune-mediated adverse events between the tiragolumab and control groups, indicating no new safety concerns.
SKYSCRAPER-02: Tiragolumab in Combination With Atezolizumab Plus Chemotherapy in Untreated Extensive-Stage Small-Cell Lung Cancer.Rudin, CM., Liu, SV., Soo, RA., et al.[2023]
Atezolizumab, combined with carboplatin and etoposide, significantly improves overall survival and progression-free survival in patients with extensive-stage small cell lung cancer, based on data from the IMpower133 trial involving previously untreated patients.
The treatment regimen is generally well tolerated, with no new safety concerns identified, and it does not negatively impact patients' quality of life, making it a valuable first-line therapy option.
Atezolizumab: A Review in Extensive-Stage SCLC.Frampton, JE.[2021]
In a study of 99 previously untreated patients with extensive disease small cell lung cancer (ED-SCLC), adding atezolizumab to the standard carboplatin and etoposide regimen significantly improved overall survival, extending it to 20.8 months compared to 12.1 months for those receiving carboplatin and etoposide alone.
While there was no significant difference in progression-free survival between the two treatment groups, certain subgroups (such as older patients, males, and those with better health status) showed particularly enhanced survival benefits from the addition of atezolizumab, indicating its potential for personalized treatment approaches.
