Immutep: Positive Overall Response in Phase II Trial in 1st line NSCLC for PD-L1 All-Comers

 

  • TACTI-002 has met its primary objective for 1st line non-small cell lung cancer (NSCLC) patients in a PD-L1 all-comer Phase II clinical trial conducted in collaboration with MSD (N=114)

  • Combination of efti plus pembrolizumab shows favourable anti-tumour activity:

    • Improved Overall Response Rate (ORR) by local read of 38.6% (intent to treat, 44/114 patients) and 42.7% (evaluable patients, 44/103) compared with data reported at ASCO 2021 (N=36)

  • Encouraging responses observed in all PD-L1 status groups, including those patients with PD-L1 negative (TPS < 1%) and PD-L1 low (TPS 1-49%) expressing tumours who are less likely to respond to anti-PD-1 monotherapy

  • Other secondary endpoints including Disease Control Rate (DCR) and interim median Progression Free Survival (PFS) continue to demonstrate improvement across all PD-L1 expression levels

  • Safe and well tolerated, with a safety profile that is consistent with that observed in previously reported studies for pembrolizumab monotherapy

  • Results support continued late stage clinical development of efti
