Cetuximab for the Treatment of Advanced Unresectable or Metastatic Chordoma

Inclusion Criteria: * Age ≥ 18 years * Histologically confirmed diagnosis of chordoma which is advanced (unresectable) and/or metastatic * ECOG Performance Status of ≤ 2 * At least one site of measurable disease on x-ray/CT/MRI and/or PET/CT scan as defined by RECIST 1.1 criteria. Baseline imaging must be performed within 30 days of Day 1 of study. * Adequate organ function within 28 days of Day 1 of study defined as: * The patient has adequate hematologic function, as evidenced by an absolute neutrophil count (ANC) ≥ 1000/µL, hemoglobin ≥ 9 g/dL (5.58 mmol/L), and platelets ≥ 100,000/µL * The patient has adequate hepatic function as defined by a total bilirubin ≤1.5 mg/dL (25.65 μmol/L) (NOTE: Patients with elevated bilirubin secondary to Gilbert's disease are eligible to participate in the study), and aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3.0 times the upper Page 26 limit of normal (ULN; or 5.0 times the ULN in the setting of liver metastases). * The patient has adequate renal function as defined by a serum creatinine ≤1.5 times the ULN, or creatinine clearance (measured via 24-hour urine collection) ≥40 mL/minute (that is, if serum creatinine is \>1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed). 3.1.6 Patients may have any prior line of therapy, but there should a washout period of at least 3 weeks from any systemic therapy (small molecule/targeted agents, immunotherapies) and/or radiation therapy.…
