BAVENCIO® (avelumab) is the first and only FDA-approved anti-PD-L1 immunotherapy for metastatic Merkel cell carcinoma (mMCC)1

BAVENCIO has been prescribed for more than 1750 US mMCC patients2*

*Estimate is based on IQVIA US sales and prescription data from April 2017 to May 2019.

JAVELIN Merkel 200 is the largest trial of immunotherapy in metastatic MCC with the longest patient follow-up to date3-5

A Phase 2, open-label, single-arm, multicenter trial

According to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as measured by blinded independent central review committee. 

Assessed by independent central review committee.

  • BAVENCIO was administered at 10 mg/kg IV infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity
  • Patients were premedicated with an antihistamine and acetaminophen prior to each infusion
  • Patients with radiological disease progression not associated with significant clinical deterioration§ could continue treatment
  • Tumor response assessments were performed every 6 weeks
  • The efficacy analysis was conducted when the last patient enrolled had completed 12 months of follow-up

§Absence of significant clinical deterioration was defined as no new or worsening symptoms, no change in performance status for  ≥ 2 weeks, and no need for salvage therapy.


Patient characteristics in the 2nd-line+ cohort

  • Median age of 73 years
  • Progression after receiving 1 or more lines of chemotherapy for distant mMCC
    • 35% of patients had 2 or more lines of previous therapy
    • 65% of patients had 1 line of previous therapy
  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0-1
  • The JAVELIN Merkel 200 trial included patients regardless of PD-L1 tumor expression or presence of Merkel cell polyomavirus (MCPyV)
  • Exclusion criteria included autoimmune disease; medical conditions requiring systemic immunosuppression; prior organ or allogeneic stem cell transplantation; prior treatment with anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibodies; central nervous system (CNS) metastases; infection with HIV, hepatitis B, or hepatitis C; or ECOG performance score ≥ 2

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

One-third of patients had an overall response


Complete responses were also observed

  • 11% (n=10/88) complete response (95% CI, 6.6-19.9)3
  • 22% (n=19/88) partial response (95% CI, 13.5-31.7)3

||Response criteria were defined according to RECIST v1.1.

  Cl=confidence interval.

35% (n=31/88) of study patients had received 2 or more lines of previous therapy

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


Durable responses extended beyond 1 year

The median duration of response had not yet been reached at the time of analysis, with a minimum follow-up of 12 months.


45% (n=13/29) of responses to BAVENCIO lasted for at least 1 year

29 of 88 patients had a complete or partial response2






In the JAVELIN Merkel 200 study2:

  • Tumor response assessments were performed every 6 weeks
  • 76% (n=22/29) of responses were seen by the first observation
  • 72% (n=21/29) of responses were ongoing at the time of data cutoff

Responses after at least 2 years of follow-up

In a subsequent analysis of the JAVELIN Merkel 200 study, with a minimum follow-up of 2 years (data cutoff on September 26, 2017), which did not account for censoring

Responses lasted beyond 2 years

  • 90% of responses lasted for at least 6 months (n=26/29; range: 2.8 to 31.8 months)
  • 66% of responses lasted for at least 1 year (n=19/29; range: 2.8 to 31.8 months)
  • 37% of responses lasted for at least 2 years (n=9/29; range: 2.8 to 31.8 months)

These data on duration 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. 

In this follow-up analysis, the minimum follow-up was 24 months.

Adverse reactions (≥ 10%) from JAVELIN Merkel 200 trial

aFatigue is a composite term that includes fatigue and asthenia.

bInfusion-related reaction is a composite term that includes drug hypersensitivity, hypersensitivity, chills, pyrexia, back pain, and hypotension.

cPeripheral edema is a composite term that includes peripheral edema and peripheral swelling.

dMusculoskeletal pain is a composite term that includes back pain, myalgia, neck pain, and pain in extremity.

eAbdominal pain is a composite term that includes abdominal pain and abdominal pain upper.

fRash is a composite term that includes rash maculopapular, erythema, and dermatitis bullous.

gPruritus is a composite term that includes pruritis and pruritis generalized.

hDyspnea is a composite term that includes dyspnea and dyspnea exertional.

  • Serious adverse reactions that occurred in more than one patient were acute kidney injury, anemia, abdominal pain, ileus, asthenia, and cellulitis
  • The most common adverse reactions (≥ 20%) were fatigue (50%), musculoskeletal pain (32%), diarrhea (23%), nausea (22%), infusion-related reaction (22%), rash (22%), decreased appetite (20%), and peripheral edema (20%)
  • 7% (6/88) of patients permanently discontinued treatment due to adverse reactions
    • Adverse reactions resulting in permanent discontinuation were ileus, Grade 3 transaminitis, Grade 3 creatine kinase elevation, tubulointerstitial nephritis, and Grade 3 pericardial effusion
  • 24% (21/88) of patients temporarily discontinued treatment due to adverse events*
    • The most common adverse event requiring dose interruption was anemia

*Excluding temporary dose interruption for infusion-related reactions where infusion was restarted the same day.

The median duration of exposure to BAVENCIO was 4 months (range: 2 weeks to 21 months). 40% of patients received BAVENCIO for more than 6 months and 14% were treated for more than one year

No new safety signals were observed in a 2-year follow-up3

Metastatic Merkel cell carcinoma (mMCC) is an aggressive disease with poor survival after distant metastasis7,8

Poor historical survival in metastatic MCC8


MCC is rare, but the incidence is growing


  • Patients with early-stage disease often experience recurrence and develop metastasis10,11
