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.

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

  2. Patients demonstrating disease progression after treatment with available therapies that are known to confer clinical benefit, or who are intolerant to treatment,
  3. Agreement to provide mandatory archival tissue or fresh biopsy.
  4. At least 18 years of age.

Exclusion Criteria:

  1. Active or chronic corneal disorder, history of corneal transplantation, active herpetic keratitis, and active ocular conditions requiring ongoing treatment/monitoring

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
Measure Description
Time Frame
The Number of Subjects Experiencing a Dose Limiting Toxicity at Various Dose Levels When Given CX-2009 as a Monotherapy
Time Frame: 21 days for the Q3W schedule, 28 days for the Q2W schedule
All AEs will be captured according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.03 and considered for assessment of DLTs as outlined by the criteria in Protocol Table 5.
21 days for the Q3W schedule, 28 days for the Q2W schedule

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
Measure Description
Time Frame
Subjects Experiencing Anti-cancer Activity (ORR) at Various Dose Levels When Given CX-2009 as a Monotherapy
Time Frame: Median total on-study follow-up of 18.4 weeks.

Efficacy will be assessed via objective response rate (ORR) by RECIST version 1.1. ORR is defined as the percentage of patients with complete response (CR) or partial response (PR) on two consecutive tumor assessments with scan dates at least 4 weeks apart according to RECIST (version 1.1, refer to SAP section 13.1.1). Complete criteria for RECIST 1.1 are provided as an appendix to the protocol.

> For as long as a subject continues follow-up for response in the study, CT/MRI/Tumor assessment are to be conducted every 8 (+/- 1) weeks from the first dose of CX 2009 with assessment for response per

> RECIST Version 1.1
Median total on-study follow-up of 18.4 weeks.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2017

Primary Completion (Actual)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
