Phase: Phase 1
Study type: Interventional

Summary:

      The primary objective of this study is to characterize the metabolic disposition,
      pharmacokinetics (PK), and routes of elimination of [14C]-labeled BVD-523 after
      administration of a single, oral dose to healthy male subjects.

      The secondary objective of this study is to evaluate the safety and tolerability of a single
      oral dose of [14C]-labeled BVD-523 in healthy male subjects.

             antibody) and negative human immunodeficiency virus (HIV) antibody screens at
             Screening

          -  Males will be surgically sterile for at least 90 days (confirmed by documented
             azoospermia) or, when sexually-active with female partners of child-bearing potential,
             will agree to use contraception as detailed in Section 6.3.3 from Check-in until 90
             days following Discharge

          -  Males must be willing to refrain from sperm donation from Check-in to 90 days from day
             of dosing

             dermatological, hepatic, renal, hematological, pulmonary, cardiovascular,
             gastrointestinal, neurological, or psychiatric disorder (as determined by the
             Investigator [or designee]) prior to Check-in

          -  History of significant hypersensitivity, intolerance, or allergy to any drug compound,
             food, or other substance, unless approved by the Investigator (or designee) prior to
