BeiGene receives European Commission Approval for Tislelizumab as treatment for Non-Small Cell Lung Cancer (NSCLC)
The European Commission (EC) has approved tislelizumab as a treatment for non-small cell lung cancer (NSCLC) across three indications, including first- and second-line use.
Tislelizumab is foundational for BeiGene’s solid tumor portfolio.
The approved indications for tislelizumab are:
- In combination with carboplatin and either paclitaxel or nab-paclitaxel for the first-line treatment of adult patients with squamous NSCLC who have locally advanced NSCLC and are not candidates for surgical resection or platinum-based chemoradiation, or metastatic NSCLC.
- In combination with pemetrexed and platinum-containing chemotherapy for the first-line treatment of adult patients with non-squamous NSCLC whose tumors have PD-L1 expression on ≥50% of tumor cells with no EGFR or ALK positive mutations and who have locally advanced NSCLC and are not candidates for surgical resection or platinum-based chemoradiation, or metastatic NSCLC.
- As monotherapy for the treatment of adult patients with locally advanced or metastatic NSCLC after prior platinum-based therapy. Patients with EGFR mutant or ALK positive NSCLC should also have received targeted therapies before receiving tislelizumab.
Tislelizumab was approved for these NSCLC indications under the brand name TIZVENI®. BeiGene plans to combine the NSCLC indications with the second-line ESCC indication under the brand name TEVIMBRA®, which will launch in the first EU countries later in 2024. TEVIMBRA is approved in the U.S. and EU for advanced or metastatic ESCC after prior chemotherapy and is under review by the European Medicines Agency and the U.S. Food and Drug Administration as a first-line treatment for patients with unresectable, recurrent, locally advanced or metastatic ESCC and for first-line gastric or gastroesophageal junction cancers.
The EC approval is based on the results from three Phase 3 studies in the RATIONALE program that enrolled 1,499 patients:
- RATIONALE 307 (NCT03594747) is an open-label, randomized Phase 3 trial that enrolled 360 patients with advanced squamous NSCLC. The study met its primary endpoint, with first-line tislelizumab in combination with chemotherapy resulting in statistically significant improvement in progression free survival (PFS), as well as higher objective response rates and a manageable safety/tolerability profile, regardless of PD-L1 expression. The most common grade ≥3 treatment emergent adverse events (TEAEs) were decreased neutrophil levels, neutropenia and leukopenia. See full study results published in JAMA Oncology.
- RATIONALE 304 (NCT03663205) is an open-label, randomized Phase 3 trial that enrolled 334 patients with locally advanced or metastatic non-squamous NSCLC. The study met its primary endpoint, with first-line tislelizumab in combination with chemotherapy resulting in statistically significant improvement in PFS compared to chemotherapy (HR: 0.65 [95% CI: 0.47-0.91]; P=0.0054) along with higher response rates and longer response duration. The most common grade ≥3 TEAEs were associated with chemotherapy and included neutropenia and leukopenia. See full study results published in the Journal of Thoracic Oncology.
- RATIONALE 303 (NCT03358875) is an open-label, randomized Phase 3 trial with tislelizumab versus docetaxel that enrolled 805 patients with advanced NSCLC who progressed on prior platinum-based chemotherapy. The study met its primary endpoint, with second- or third-line tislelizumab resulting in statistically significant and clinically meaningful improvement in overall survival compared with docetaxel in the intent-to-treat population (HR: 0.66 [95% CI: 0.56-0.79]; P<0.0001), regardless of PD-L1 expression. The most commonly reported grade ≥3 TEAEs were pneumonia, anemia and dyspnea. See full study results published in the Journal of Thoracic Oncology.
BeiGene has launched more than 17 potentially registration-enabling trials with tislelizumab, of which 11 Phase 3 randomized trials and four Phase 2 trials have already had positive readouts. Through these trials, tislelizumab has demonstrated its potential to deliver clinically meaningful improvements in survival benefits and quality of life for hundreds of thousands of cancer patients across a range of tumor types – in many cases, regardless of PD-(L)1 status – both as monotherapy and in combination with other regimens. More than 900,000 patients have been prescribed tislelizumab globally to date.
