As a companion piece to our recent survey looking at initial use of Keytruda in first-line NSCLC patients (Physician Views Poll Results: Merck & Co.'s Keytruda gaining traction in first-line NSCLC say oncologists), our last Physician Views poll of 2016 assesses how approval of Merck & Co.'s PD-1 inhibitor in the front-line setting is impacting use of immunotherapy in second-line patients.
Since approval last year, Bristol-Myers Squibb's competing PD-1 inhibitor Opdivo has dominated the second-line NSCLC market, thanks largely to a broad label which does not require PD-L1 biomarker testing prior to use. However, with more patients now being tested for PD-L1 status when initially diagnosed with NSCLC (to assess eligibility for first-line treatment with Keytruda) this commercial dynamic is expected to change. Furthermore, Roche's Tecentriq – a PD-L1 inhibitor offering similar, if not slightly superior, efficacy based on available data – was approved in October for the treatment of second-line NSCLC patients irrespective of PD-L1 status (ViewPoints: Roche's Tecentriq could hit the ground running).
To ascertain whether approval of Keytruda in front-line NSCLC patients is having any impact on second-line treatment trends we are asking US-based oncologists the following questions…
Assuming a first-line NSCLC patient receiving Keytruda monotherapy experienced either progression or recurrence of their disease, would you prescribe another PD-1 or PD-L1 inhibitor as a second-line therapy?
Yes – Favour Opdivo
Yes – Favour Tecentriq
Yes – Either Opdivo or Tecentriq
For first-line NSCLC patients who have experienced either progression or recurrence of their disease following treatment with chemotherapy, would you favour a particular PD-(L)1 inhibitor for second-line therapy?
Yes – Keytruda
Yes – Opdivo
Yes – Tecentriq
For which reason primarily did you select that product?
Familiarity with use of product/biomarker assay in first-line patients
Familiarity with product in second-line patients
PD-L1 status of patient (i.e. either PD-L1 negative or PD-L1 >1%)
Perception of clinical profile for that product
Dosing regimen for that product
Perception of product manufacturer
Other (please state)
Do you stratify second-line NSCLC patients by PD-L1 status to determine treatment with a particular product?
Yes – 1% or above favour Keytruda / PD-L1 negative favour Opdivo
Yes – 1% or above favour Keytruda / PD-L1 negative favour Tecentriq
Yes – 1% or above favour Keytruda / PD-L1 negative use Opdivo or Tecentriq
In 12 months' time, which of the following PD-(L)1 inhibitor products would you expect to be used most frequently in second-line patients?
