A Phase 1 Study of IXAZOMIB in Adult Patients With Advanced Nonhematologic Malignancies
- Registration Number
- NCT00830869
- Lead Sponsor
- Millennium Pharmaceuticals, Inc.
- Brief Summary
This is an open-label, multicenter, phase 1, dose escalation study of IXAZOMIB. The primary purpose of this study is to determine the safety profile, establish the maximum tolerated dose, and inform the phase 2 dose of IXAZOMIB administered intravenously in participants with nonhematologic malignancies.

Each participant must meet all of the following inclusion criteria to be enrolled in the study:
-
Male or female participants 18 years or older.
-
Eastern Cooperative Oncology Group performance status 0-2.
-
A diagnosis of a nonhematologic malignancy for which standard treatment is no longer effective. In the expanded cohort, enrollment will be limited to participants with a diagnosis of NSCLC, H&N cancer (squamous cell cancer), STS, or PC.
-
Suitable venous access for pharmacokinetic (PK) and pharmacodynamic evaluations.
-
Female participants who are post menopausal, surgically sterile, or agree to practice 2 effective methods of contraception or abstain from heterosexual intercourse.
Male participants who agree to practice 2 effective methods of contraception or abstain from heterosexual intercourse.
-
Voluntary written consent must be obtained.
-
Adequate clinical laboratory values during the screening period.
-
In the escalation portion of the study, radiographically or clinically evaluable tumor was required, but measurable disease as defined by response evaluation criteria in solid tumors (RECIST) criteria was not required. In the MTD disease expansion cohorts and the TPEC, clinically measurable disease as defined by RECIST criteria was required for evaluation of NSCLC, H&N cancer, and STS. Prostate specific antigen (PSA) alone was acceptable for evaluation of PC.
-
For participants in the TPEC, tumor tissue that, in the opinion of the investigator, could have been safely biopsied using a core needle.

Number of Participants With Best Overall Response Day 18 up to Day 21 of each cycle (Part 1: up to Cycle 10; Part 2: up to Cycle 12) Best overall response for a participant is best observed post-baseline disease response as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.0 criteria. Complete Response (CR): disappearance of all target lesions, non-target lesions and normalization of tumor marker level. Partial Response (PR): at least 30% decrease in sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the baseline smallest sum of longest diameter; persistence of 1 or more non-target lesion(s) or maintenance of tumor marker level above normal limits. Progressive disease: at least 20% increase in the sum of the longest diameter of target lesions, taking as reference the baseline smallest sum of longest diameter or appearance of 1 or more new lesions or unequivocal progression of existing non-target lesions.
