Active Ingredient: Sugemalimab
Sugemalimab as monotherapy is indicated for the treatment of unresectable stage III NSCLC with no sensitising EGFR mutations, or ALK, ROS1 genomic tumour aberrations in adults whose tumours express PD-L1 on ≥1% of tumour cells and whose disease has not progressed following platinum-based chemoradiotherapy.
For this indication, competent medicine agencies globally authorize below treatments:
For:
Regimen A, in case that patient weight is ≤ 115 kg
Intravenous, 1,200 milligrams sugemalimab, once every 3 weeks.
Regimen B, in case that patient weight is > 115 kg
Intravenous, 1,500 milligrams sugemalimab, once every 3 weeks.
The use of systemic corticosteroids or immunosuppressants before starting sugemalimab should be avoided.
Table 1. Recommended dose for sugemalimab by intravenous administration:
| Indication | Recommended dose and schedule | Duration of Treatment |
|---|---|---|
| Sugemalimab monotherapy | ||
| Unresectable Stage III NSCLC consolidation treatment | • 1200 mg (for individuals weighing 115 kg or less) every 3 weeks or • 1500 mg (for individuals weighing more than 115 kg) every 3 weeks | Treatment should be continued until disease progression, or unacceptable toxicity. |
The dose of sugemalimab should not be increased or reduced. Treatment withholding or discontinuation may be required based on individual safety and tolerability. Recommended treatment modifications are provided in Table 2.
