CBT-1® in Combination With Doxorubicin in Patients With Metastatic, Unresectable Sarcomas Who Previously Progressed on Doxorubicin

August 16, 2019 updated by: CBA Research

A Phase I Trial of CBT-1® in Combination With Doxorubicin in Patients With Locally Advanced or Metastatic, Unresectable Sarcomas Previously to Have Progressed on 150 mg/m2 or Less of Doxorubicin

This study evaluates the combination of CBT-1® and doxorubicin for the treatment of metastatic, unresectable sarcoma in patients who have progressed after treatment with 150mg/m2 or less of doxorubicin. Participants will receive CBT-1® on days 1-7 of each 21-day cycle, as well as doxorubicin on days 5 and 6.

Intervention / Treatment

Intervention / Treatment

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: 3 years
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Recommended phase 2 dose (RP2D) of CBT-1® when combined with doxorubicin
Time Frame: 3 years
3 years

week 12
Overall Response Rate
Time Frame: 3 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
Correlation of DCR, ORR and PFS to disease subtype
Time Frame: 3 years

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
