Phase I Dose Escalation Study of AB-16B5 in Subjects With an Advanced Solid Malignancy

June 27, 2017 updated by: Alethia Biotherapeutics

A Phase I Dose-Escalation Study to Evaluate the Safety, Tolerability and Pharmacokinetics of AB-16B5 in Subjects With an Advanced Solid Malignancy

This is a Phase 1 clinical study to investigate the safety, pharmacokinetics and pharmacodynamics of AB-16B5 in patients with an advanced solid malignancy. AB-16B5 is a humanized monoclonal antibody that inhibits the activity of the secreted form of clusterin (sCLU), a potent inducer of the epithelial-to-mesenchymal transition (EMT). Eligible subjects will have a disease that has been refractory to prior therapy and is unlikely to benefit from known therapies.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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)

  • Subjects must understand and be able and willing and likely to fully comply with the study procedures, including scheduled follow-up, and restrictions.
  • Subjects must have given written personally signed and dated informed consent to participate in the study, in accordance with the International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines, before completing any study related procedures.

Exclusion Criteria:

  • Subjects with medical, social, or psychosocial factors that, in the opinion of the Investigator, could impact safety or compliance with study procedures.

  • Uncontrolled brain metastases.
  • Uncontrolled infection.
  • Clinically significant ECG abnormalities.
  • Known hypersensitivity of Grade > 2 to previous monoclonal antibody therapy.
  • History of alcohol or other substance abuse within the last year.

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.
Outcome Measure
Time Frame
Number of participants with an adverse event as a measure of safety and tolerability
Time Frame: Up to treatment discontinuation + 30 days with an estimated treatment duration of 6 to 24 weeks
Up to treatment discontinuation + 30 days with an estimated treatment duration of 6 to 24 weeks

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
Time Frame
Determination of plasma concentrations of AB-16B5
Time Frame: Several time-points during Cycle 1 and Cycle 2 for a total of 6 weeks
Several time-points during Cycle 1 and Cycle 2 for a total of 6 weeks
