Reason
Safety related (clinical or pre-clinical results)
Explanation
While there are confounding factors in these cases, in keeping with the highest level of commitment to patient safety, Incyte is conducting an expedited comprehensive review of safety of INCB161734 to assess the overall risk of pneumonitis/interstitial lung disease. Enrollment into the INCB161734-101 study is paused (including those participants in screening) until further notice pending completion of formal safety review.
Follow-up measures
Currently enrolled participants may continue study treatment at their current dose of INCB161734 after discussion with the treating physician. Ongoing participants should be notified of these events, appropriately counseled on symptoms of pneumonitis such as cough and shortness of breath, and instructed to report development of any such symptoms immediately. Protocol required safety monitoring of ongoing participants should continue as currently specified. If an ongoing participant develops symptoms concerning for pneumonitis or radiologic evidence of potential pneumonitis of any grade, INCB161734 should be immediately held as per current protocol guidance (Section 6.6.3, Table 13), and the Sponsor should be immediately notified. The Sponsor will communicate findings of the comprehensive safety review and update the ICF and IB as soon as the review is complete.
