Safety Study of rhuMAb 2C4 to Treat Advanced Solid Tumors

The purpose of this Phase I study is to test the safety of rhuMAb 2C4 to see what effects (good and bad) it has on patients with certain types of cancer, and also to find the highest dose of rhuMAb that can be given without causing severe side effects. All study participants will be assigned to specific group to evaluate different dosages of rhuMAb 2C4. The study is scheduled to run for up to one year depending on how patients respond to the study treatment.

  • Serum creatinine less than or equal to ULN or creatinine clearance of >=60 mL/min
  • International normalized ratio (INR) of <1.3 and activated partial thromboplastin time (aPTT) of <1.5x ULN

Exclusion criteria

  • Pleural effusions, ascites, or bone lesions as the only manifestation of the current cancer
  • Symptomatic or untreated brain metastases

  • Uncontrolled hypercalcemia (>11.5 mg/dL)
  • Clinically important history of liver disease, including viral or other hepatitis, current alcohol abuse, or cirrhosis
  • Known human immunodeficiency virus (HIV) infection
  • Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the subject at high risk from treatment complications
  • Major surgery or significant traumatic injury within 3 weeks of Day 1
  • Pregnancy or lactation
  • Inability to comply with study and follow-up procedures

Primary outcomes

  1. Number of Participants With an Adverse Event (AE), Serious Adverse Event (SAE), or Death

    Time frame: Days 1, 2, 5, 8, and 15 of Cycle 1; Days 1, 8, and Week 3, of Cycles 2 and beyond up to 1 year and at the follow-up visit (4 weeks after last infusion)

    For this protocol, an AE is defined any untoward medical occurrence (e.g., sign, symptom, disease, syndrome, intercurrent illness, abnormal laboratory finding) that emerges or worsens relative to pretreatment baseline during the treatment or post-treatment periods, regardless of the suspected cause.

    For this protocol an SAE was defined as any AE that occurred at any dose if:

    • It resulted in death (i.e., the AE caused or led to death),
    • It was life threatening,
    • It required or prolonged inpatient hospitalization,
    • It was disabling,
    • It resulted in a congenital anomaly/birth defect,
    • It may have jeopardized the participant or may have required medical or surgical intervention to prevent one of the outcomes listed above.

    The primary cause of death for all reported cases was disease progression, and all of the deaths occurred following study discontinuation, with one death occurring within 4 weeks of the last treatment day.

  2. Number of Participants With Dose-Limiting Toxicities (DLTs)

    Time frame: Day 1 of Cycles 1 and 2, and 24 hours after Cycle 2 infusion

    Incidence of DLTs defined as any Grade 3 or 4 major organ toxicity according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC) Version 2 or any subjectively intolerable toxicity felt by the investigator to be related to rhuMAb 2C4.

    One participant in the 15.0 mg/kg dose group experienced a gastrointestinal hemorrhage on Day 16. This event was judged by the investigator to be related to study drug. The participant recovered in 3 days and continued to receive rhuMAb 2C4 beyond Cycle 2.This was the only DLT reported during the first two treatment cycles.

Secondary outcomes

  1. Pharmacokinetic Measurement of Area Under the Curve (AUC)

    Time frame: Days 1 (predose, 89 minutes following start of infusion and at 1.5, 4, and 8 hours postdose) 2, 5, 8 and 15 of Cycle 1; Days 1 (predose and 29 minutes following start of infusion) and 8 of Cycle 2

    Mean rhuMAb 2C4 serum concentrations versus nominal time profiles for the first two treatment cycles are presented for AUC micrograms per milliliters (ug/mL) by day. A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.

  2. Pharmacokinetic Measurement of Systemic Clearance (CL)

    Time frame: Days 1 (predose, 89 minutes from infusion start, at 1.5, 4, and 8 hours postdose), 2, 5, 8 and 15 of Cycle 1; Days 1 (predose, 29 minutes from infusion start) and 8 of Cycles 2 and beyond until the follow-up visit (4 weeks after the last infusion)

    A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.

  3. Pharmacokinetic Measurement of Volume of Central Compartment (Vc)

    Time frame: Days 1 (predose, 89 minutes from infusion start, at 1.5, 4, and 8 hours postdose), 2, 5, 8 and 15 of Cycle 1; Days 1 (predose, 29 minutes from infusion start) and 8 of Cycles 2 and beyond until the follow-up visit (4 weeks after the last infusion)

    A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.

  4. Pharmacokinetic Measurement of Steady-State Volume of Distribution (Vss)

    Time frame: Days 1 (predose, 89 minutes from infusion start, at 1.5, 4, and 8 hours postdose), 2, 5, 8 and 15 of Cycle 1; Days 1 (predose, 29 minutes from infusion start) and 8 of Cycles 2 and beyond until the follow-up visit (4 weeks after the last infusion)

    A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.

  5. Pharmacokinetic Measurement of Initial Distribution Half-Life (t1/2 Initial)

    Time frame: Days 1 (predose, 89 minutes from infusion start, at 1.5, 4, and 8 hours postdose), 2, 5, 8 and 15 of Cycle 1; Days 1 (predose, 29 minutes from infusion start) and 8 of Cycles 2 and beyond until the follow-up visit (4 weeks after the last infusion)

    A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.

  6. Pharmacokinetic Measurement of Terminal Half-Life (t1/2 Terminal) in Days

    Time frame: Days 1 (predose, 89 minutes from infusion start, at 1.5, 4, and 8 hours postdose), 2, 5, 8 and 15 of Cycle 1; Days 1 (predose, 29 minutes from infusion start) and 8 of Cycles 2 and beyond until the follow-up visit (4 weeks after the last infusion)

    A one-compartment model was used for the 0.5 mg/kg dose group, and a two-compartment model was used for the 2-15 mg/kg dose groups.
