A Phase I, Open-label, Ascending Dose Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of the Endothelin B Agonist, SPI-1620, in Patients With Recurrent or Progressive Carcinoma

October 17, 2013 updated by: Spectrum Pharmaceuticals, Inc
This is a 2-part, open-label, single-arm, dose escalation study. Part I will define the Maximum Tolerated Dose (MTD) and optimal dose of SPI-1620 and evaluate its PK and PD properties. Once the MTD for SPI-1620 is identified, a second phase of the study will focus on dose escalation of docetaxel studied in groups of 3-6 patients. This part of the study will assess the safety and tolerability of increasing doses of docetaxel administered with the optimal dose of SPI 1620 defined in Part I.

Detailed Description

This is a 2-part, open-label, single-arm, dose escalation study. Part I will define the Maximum Tolerated Dose (MTD) and optimal dose of SPI-1620 and evaluate its PK and PD properties. Eligible patients will receive SPI-1620 delivered intravenously over one minute on Days 1, 8 and 15. On Day 8 patients will undergo a series of four H215O PET Blood Flow (BF) scans which will be used to assess alterations in BF induced by SPI-1620 in tumor and non-tumor ROIs (Region of Interest). Fifteen minutes after receiving SPI-1620 on Day 15, patients will receive docetaxel, 60 mg/m2, administered by infusion over 1 hour. Accelerated dose escalation of SPI-1620 will be employed: one patient will be treated at each dose level with 100% increases between dose levels. If any grade 2 or higher, related AE occurs, the trial will revert to 3-patient cohorts with 40% dose escalation between groups. There will be no intrapatient dose escalation. Dose escalation will continue until there is either no further increase in tumor blood flow as assessed by H215O PET scan, or until significant toxicity is observed. Once the MTD for SPI-1620 is identified, a second phase of the study will focus on dose escalation of docetaxel studied in groups of 3-6 patients. This part of the study will assess the safety and tolerability of increasing doses of docetaxel administered with the optimal dose of SPI 1620 defined in Part I. If 60 mg/m 2 was tolerated in Part I then up to six patients in Part II will receive docetaxel at a dose of 80 mg/m2 once every 3 weeks. If this is tolerated the next group of patients will receive docetaxel 100 mg/m2 once every 3 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
