Masking: None (Open label)

---

440 participants in 2 patient groups

BL-M07D1

Experimental group

Description:

Participants receive BL-M07D1 in the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Treatment:

Drug: BL-M07D1

Pembrolizumab-platinum chemotherapy

Active Comparator group

Description:

Participants receive Pembrolizumab+Pemetrexed+Carboplatin or Cisplatin in the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Treatment:

Drug: Pembrolizumab

Drug: Carboplatin

Drug: Pemetrexed

Drug: Cisplatin
