Dose Escalation Study to Assess the Safety and Tolerability of Genz-644282 in Patients With Solid Tumors

NCT00942799 | Completed Phase 1

• 1 other identifier: GZ28200108
• Study Type: interventional

Brief Summary

This is a Phase I, open-label, multicenter, dose-escalation study designed to assess the safety and tolerability of Genz-644282, administered as an intravenous (IV) infusion, to patients with advanced malignant solid tumors. Each 28 day cycle of treatment will consist of 3 consecutive weeks of treatment every 28 days(i.e., treatment will be administered on Days 1, 8, and 15 every 28 days). Each 21 day cycle of treatment will consist of 2 consecutive weeks of treatment every 21 days(i.e., treatment will be administered on Days 1 and 8 every 21 days). Treatment with Genz-644282 will continue until disease progression or unacceptable toxicity is observed. Approximately 110 patients will be enrolled in this study. Patients will be enrolled in escalating dose cohorts until the Maximum Tolerated Doses (MTDs) for the 2 dosing schedules are established. To further evaluate safety, approximately 40 additional patients with advanced malignant solid tumors will be enrolled and treated at the MTDs (20 for each dosing schedule) during an expansion phase.

Study Drug: Genz-644282 (28-day dosing schedule)

EXPERIMENTAL

Genz-644282 (Each cohort will be based on dose-escalation)

Drug: Genz-644282 (28-day dosing schedule)

Study Drug: Genz-644282 (21-day dosing schedule)

EXPERIMENTAL

Genz-644282 (Each cohort will be based on dose-escalation)

Drug: Genz-644282 (21-day dosing schedule)

Interventions

Genz-644282 (28-day dosing schedule) DRUG

Genz-644282 will be administered as a 60-minute IV infusion. The initial dose of Genz-644282 will be 0.5 mg/m2 and will be administered once weekly for 3 consecutive weeks on Day 1, Day 8, and Day 15 of the 28 day cycle. Each 28-day period will represent one treatment cycle. Study drug will continue to be given until disease progression or unacceptable toxicity is observed.

Study Drug: Genz-644282 (28-day dosing schedule)

Genz-644282 (21-day dosing schedule) DRUG

The starting dose of Genz-644282 for the 21-day schedule will be prescriptive and will be based on review of available safety data from the 28-day dosing schedule by the Investigator and Sponsor. Patients will receive Genz-644282 once-weekly for 2 consecutive weeks on Day 1 and Day 8 of a 21 day cycle. Each 21-day period will represent 1 treatment cycle. Patients enrolled in subsequent cohorts will receive higher doses until the MTD is established.

Study Drug: Genz-644282 (21-day dosing schedule)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Signed written informed consent
• Patients enrolled in dose-escalation phase: Histologically or cytologically confirmed advanced malignant solid tumor for which no standard therapeutic option exists.
• For the disease indications evaluated in the expansion phase, the following criteria must be met:
• Have one of the following histologically or cytologically confirmed advanced malignant solid tumors for which no standard therapeutic option exists:
• Colorectal cancer (prior systemic regimen must have included ≥1 of the following: fluoropyrimidine or oxaliplatin);
• Squamous Non-small cell lung cancer or small cell lung cancer (prior systemic regimen must have included ≥1 of the following: cis-platinum or carbo platinum);
• Pancreatic cancer (prior systemic regimen must have included gemcitabine);
• Breast cancer (prior systemic regimen must have included ≥1 of the following: taxane, anthracycline, or fluoropyrimidine)
• Received no more than 4 prior systemic therapy regimens for their malignancy
• Experienced progression or intolerance to their immediate prior systemic therapy regimen.
• Evaluable or measurable disease.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Life expectancy of at least 12 weeks.
• Adequate organ and hematologic function.
• Prior chemotherapy, major surgery, or irradiation must have been completed at least 3 weeks prior to starting treatment with study drug, with the exception of mitomycin-C or nitrosoureas, which should be completed at least 6 weeks prior. Additionally, patients must have recovered to ≤ Grade 1 toxicities incurred as a result of the previous therapy, with the exception of nail dystrophy, alopecia, or local radiation therapy induced adverse events (e.g., impotence or incontinence). A patient who has received radiation to \< 5% of their total bone marrow volume and who has had 2 weeks of rest may be considered for study entry after discussion with the Sponsor

You may not qualify if:

• Received previous treatment with or have a known hypersensitivity to Genz-644282 or to any of its components.
• Received radiotherapy to the only site of measurable disease, unless the tumor at this site continues to increase in size after the patient has completed radiotherapy treatment.
• Used any investigational agent, other than anti-cancer chemotherapy, during the 4 weeks prior to the first dose of Genz-644282.
• Have psychiatric disorder(s) that would interfere with consent, study participation, or follow up (with the possible exception of incompetence as defined by New Jersey for the purposes of participation in clinical trials in the state of New Jersey).
• Have uncontrolled congestive heart failure or angina, a history of myocardial infarction within 6 months prior to study enrollment, or a cardiac functional capacity Class III or IV, as defined by the New York Heart Association Classification.
• Have a resting QT with Bazett's correction (QTcB) interval of \> 460 msec, calculated as the average of at least 2 of the longest QT intervals measured on 12-lead recordings made prior to dosing with Genz-644282.
• Have a systemic fungal, bacterial, viral, or other infection that is not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement) despite appropriate antibiotics or other treatment.
• Have any other severe concurrent disease or a history of serious organ dysfunction or disease involving the heart, kidney, liver, or other organ system that may place the patient at undue risk to undergo chemotherapy.
• A known diagnosis of human immunodeficiency virus (HIV) infection or acquired immune deficiency syndrome (AIDS) or viral hepatitis B or C.
• Presence of ≥ Grade 2 peripheral neuropathy.
• Pregnant or lactating women, due to the unknown effects of Genz-644282 on the developing fetus or newborn infant.
