OVERALL RESPONSE RATE (ORR)

Accelerated approval based on data from JAVELIN Merkel 200–the largest trial of immunotherapy in metastatic MCC (N=88)2

In the Phase 2, open-label, single arm, multicenter study of 88 patients with mMCC whose disease progressed on or after chemotherapy for distant metastatic disease2:

ONE-THIRD OF PATIENTS HAD AN OVERALL RESPONSE

33% ORR*

(95% CI: 23.3, 43.8) (n=29/88)

  • Complete response – 11% (n=10/88) (95% CI: 6.6, 19.9)
  • Partial response – 22% (n=19/88) (95% CI: 3.5, 31.7)

35% (n=31/88)

of patients had received ≥2 lines of previous therapy

Responses were observed regardless of PD-L1 tumor expression or presence of Merkell cell polyomavirus (MCPyV)

*Response criteria were defined according to RECIST v1.1.
CI=confidence interval.

DURATION OF RESPONSE

Durable responses extended beyone one year

29 patients experienced a confirmed response, with almost half lasting at least 1 year (range: 2.8 to 23.3+ months)

Responses lasting ≥6 months

86%

(n=25/29)

Responses lasting ≥1 year

45%

(n=13/29)

  • 76% (n=22/29) of responses were seen by the first observation3
  • 72% (n=21/29) of responses were ongoing at the time of data cutoff3
  • The median duration of response had not yet been reached at the time of analysis, with a minimum follow-up of 12 months3

2-YEAR FOLLOW-UP*

In a subsequent, uncensored analysis of the JAVELIN Merkel 200 Trial, responses lasted beyond 2 years (range: 2.8-31.8 months)3*

  • Responses lasting ≥6 months

    90%

    (n=26/29)

  • Responses lasting ≥1 year

    66%

    (n=19/29)

  • Responses lasting ≥2 years

    31%

    (n=9/29)

*These data on durations of response are based on different data with a minimum of 2 years of follow-up in all patients (EMR 100070-003) Part A; cutoff date September 26, 2017). The relative frequencies presented do not account for censoring.
