ECOG 0–1(Restricted strenuous activity)

Prior therapy

Cannot have received: tubulin-inhibitor-based drug conjugate (Emrelis, Elahere)

Exception: prior treatment with standard taxane-based chemotherapy (e.g., paclitaxel) is permitted

Prior treatment with tubulin-inhibitor-based drug conjugates, including antibody-drug conjugates (ADCs) with tubulin inhibitor payloads, ie, Emrelis (MMAE payload) for c-Met-high NSCLC or Elahere (DM4 payload) for FRα-high ovarian cancer. For clarity, prior treatment with standard taxane-based chemotherapy (eg, paclitaxel) is permitted.

Lab requirements

Blood counts

ANC ≥1.5×10^9/L; Platelets ≥100×10^9/L without transfusion support within 14 days prior to study treatment; Hemoglobin ≥9.0 g/dL without transfusion support within 14 days prior to study treatment; Coagulation tests ≤1.5×ULN unless subject is receiving anticoagulant therapy, as long as PT, INR, or aPTT is within the therapeutic range of intended use of anticoagulants

Kidney function

Calculated creatinine clearance ≥60 mL/min by Cockcroft-Gault formula or CKD-EPI

Liver function

AST and ALT ≤2.5×ULN or ≤5×ULN for subjects with liver metastases; total serum bilirubin ≤1.5×ULN except in the presence of Gilbert's Syndrome where direct bilirubin should be ≤ULN
