This study assesses the tolerability, safety, efficacy and pharmacokinetics of Bardoxolone methyl (RTA 402) in advanced solid tumors and lymphoid malignancies.

Condition Intervention Phase
Advanced Solid Tumors
Lymphoid Malignancies
Drug: Bardoxolone methyl
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase I Dose-finding and Pharmacokinetic Study of RTA 402 (CDDOMe) Administered Orally for 21 Days of a 28-day Cycle in Patients With Advanced Solid Tumors or Lymphoid Malignancies

Further study details as provided by Reata Pharmaceuticals, Inc.:

Primary Outcome Measures:
  • To determine the dose-limiting toxicity, maximum tolerated dose, and recommended phase II dose of Bardoxolone methyl Capsules [ Time Frame: 28 day cycles, with a maximum of 18 cycles (18 months) ]
  • To characterize the pharmacokinetics of Bardoxolone methyl in this patient population. [ Time Frame: 28 day cycles, with a maximum of 18 cycles (18 months) ]

Secondary Outcome Measures:
  • To document any preliminary antitumor activity. [ Time Frame: 28 day cycles, with a maximum of 18 cycles (18 months) ]
  • To determine the in vivo molecular and biological effects. [ Time Frame: 28 day cycles, with a maximum of 18 cycles (18 months) ]
  • To correlate the biological activity of RTA 402 with drug concentration in plasma and blood cellular elements. [ Time Frame: 28 day cycles, with a maximum of 18 cycles (18 months) ]

Enrollment: 47
Study Start Date: April 2006
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bardoxolone methyl capsules

Bardoxolone methyl to be taken orally for 21 consecutive days, once a day, in the morning prior to food intake.

Patients to continue to receive treatment for the first 21 days of each 28-day cycle until they experience intolerable toxicity, show evidence of disease progression, or receive a maximum of 18 cycles (18 months).

Drug: Bardoxolone methyl
Other Name: RTA 402

Detailed Description:
Bardoxolone methyl (RTA 402) is a synthetic triterpenoid that has demonstrated significant in vivo single agent anti-cancer activity. This is an open-label phase I dose-escalation study of Bardoxolone methyl (RTA 402) administered orally for the first 21 days of a 28-day cycle.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histopathological documentation of solid tumor or lymphoid malignancy.
  • Advanced or metastatic cancer that is either refractory to or have relapsed after standard-of-care curative or survival-prolonging therapy, or for whom no such therapies exist.
  • ECOG performance status of less than or equal to 2
  • Adequate liver and renal function as documented by the following laboratory test results within 14 days of starting therapy: total bilirubin ≤ 1.5 mg/dL; AST (SGOT) and ALT(SGPT) ≤ 2.5 ULN or ≤ 5 ULN if liver is involved by tumor; serum creatinine ≤2.0 mg/dL OR creatinine clearance >60 mL/min.
  • Adequate bone marrow function as documented by the following laboratory test results within 14 days of starting therapy: platelets greater than 100,000/mm3, absolute granulocyte count greater than 1,500/mm3, hemoglobin greater than or equal to 8.0 g/dl.
  • Completion of prior chemotherapy, hormonal therapy, radiation therapy, biological therapy, or other investigational cancer therapy, for at least 4 weeks prior to study entry and must have recovered from all acute side effects (to CTC grade 1 or less) prior to initiation of RTA 402. Patients who were receiving mitomycin C or nitrosoureas must be 6 weeks from the last administration of chemotherapy.
  • Agree to practice effective contraception during the entire study period.
  • Life expectancy of more than 3 months
  • Able and willing to sign the informed consent form.
  • Willing and able to self-administer orally and document all doses of RTA 402 ingested.

Exclusion Criteria:

  • Active brain metastases or primary CNS malignancies.
  • Pregnant or breast feeding
  • Clinically significant illnesses including, but not limited to: Uncontrolled diabetes; Active or uncontrolled infection; Acute or chronic liver disease; Confirmed diagnosis of HIV infection; Uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, or uncontrolled cardiac arrhythmia.
  • Psychiatric illness that would limit compliance with study requirements.
