About this study

Official title: A Phase I/II Study of CG200745 PPA to Determine the Maximum Tolerated Dose and Evaluate the Safety and Efficacy in Patients With Myelodysplastic Syndrome (MDS) Who Failed to Respond to Prior Hypomethylating Therapy

<Part I - Phase I trial> The phase I clinical trial is to identify the MTD (Maximum Tolerated Dose) and DLT (Dose Limiting Toxicity) of CG200745 PPA. Initial dose of CG200745 PPA is 150 mg/m^2, and it will be extended to 225 mg/m^2, 300 mg/m^2 or it will be reduced to 75 mg/m^2 based on the results of the cohort of 3 to 6 subjects per dose level.

Based on the 3+3 dose escalation study design, CG200745 PPA is to be administered according to the dose level. Each cohort consists of 3 or 6 subjects.

<Part II - Phase II trial> In the phase II clinical trial, the subjects will be administered with the dose which is to be identified as a recommended dose based on the results of Phase I study. Each cycle consisted of 28 days, same as the phase I. The entire treatment period is 6 cycles and tumor assessment is to be evaluated at the end of every 2 cycles.

<Part I - Phase I trial> The phase I clinical trial is to identify the MTD and DLT of CG200745 PPA. Initial dose of CG200745 PPA is 150 mg/m^2, and it will be extended to 225 mg/m^2, 300 mg/m^2 or it will be reduced to 75 mg/m^2 based on the results of the cohort of 3 - 6 subjects per dose level.

Based on the 3+3 dose escalation study design, CG200745 PPA is to be administered as in four different cohorts according to the dose level. Each cohort consists of 3 or 6 subjects.

  • Dose Level -1: CG200745 PPA 75 mg/m^2 x 5 (375 mg/m^2/cycle) / -50%
  • Dose Level 1: CG200745 PPA 150 mg/m^2 x 5 (750 mg/m^2/cycle) / initial base dose
  • Dose Level 2: CG200745 PPA 225 mg/m^2 x 5 (1,125 mg/m^2/cycle) / 50%
  • Dose Level 3: CG200745 PPA 300 mg/m^2 x 5 (1,500 mg/m^2/cycle) / 33%

<Part II - Phase II trial> In the phase II clinical trial, the subjects will be administered with the dose which is to be identified as a recommended dose based on the results of Phase I study. Each cycle consisted of 28 days, same as the phase I. The entire treatment period is 6 cycles and tumor assessment is to be evaluated at the end of every 2 cycles.

What is being measured

The primary outcome is the main question the study is designed to answer.

    Measured: up to 6 cycles (each cycle is 28 days)

Secondary outcomes (4)
  1. Area Under the Curve [AUC]

    Pharmacokinetics (PK) parameter

    Measured: Part I, Cycle 1, Day 1, up to 6 days

  2. Maximum Plasma Concentration [Cmax]

    Pharmacokinetics (PK) parameter

    Measured: Part I, Cycle 1, Day 1, up to 6 days

  3. Adverse Event

    Safety parameter

    Measured: up to 6 cycles

  4. Clinical laboratory tests

    Safety parameter

    Measured: up to 6 cycles

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CG200745 PPA in people with Myelodysplastic Syndrome, run by CrystalGenomics, Inc. at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate (ORR) (time frame: up to 6 cycles (each cycle is 28 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Sep 2023.
