For patients with mCSCC or laCSCC who received LIBTAYO 3 mg/kg Q2W in Study 1540 (n=137)1†:

LIBTAYO objective response rates
  • 79% of responders (50 out of 63) reached a DOR ≥6 months1,5‡
  • 54% of responders (34 out of 63) reached a DOR ≥12 months1,5‡
  • Median TTR was 1.9 months (range, 1.7-9.1 months)1

In an additional cohort in Study 1540 of 56 patients with mCSCC who received LIBTAYO 350 mg Q3W1†:

  • ORR was 41% (23 out of 56 patients [95% CI, 28%-55%])1‡
  • 65% of responders (15 out of 23) reached a DOR ≥6 months1

In this trial, median DOR was not reached (range, 1.9-24.2+ months).1‡

The recommended dosage of LIBTAYO is 350 mg administered as an intravenous infusion over 30 minutes every 3 weeks until disease progression or unacceptable toxicity.1

  • Data cutoff was September/October 2018.5
  • Median duration of follow-up was 11.1 months and 8.0 months in patients who received LIBTAYO 3 mg/kg Q2W and LIBTAYO 350 mg Q3W in Study 1540, respectively.1
  • See additional study design details inside.1
  • §PR is defined as a decrease of ≥30% in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters, per RECIST 1.1. PR of externally visible disease is defined as a decrease of ≥50% in the sum of products of perpendicular longest dimensions of target lesions, per WHO Criteria. Nontarget lesions could not have progressive disease and there could be no new lesions. Responses had to be maintained for at least 4 weeks.1,5
  • ||CR is defined as disappearance of all target lesions for at least 4 weeks. Nontarget lesions also had to show a CR and there could be no new lesions. Any pathological lymph nodes (whether target or nontarget) must have shown a reduction in short axis to <10 mm (<1 cm). Only includes patients with complete healing of prior cutaneous involvement; patients with laCSCC in Study 1540 required biopsy to confirm a CR.1,5
  • Plus sign (+) denotes ongoing at last assessment.1
