About this study

Official title: Phase I Clinical Trial of SyB C-1101 in Patients With Myelodysplastic Syndrome

The purpose of this study is to investigate tolerability when SyB C-1101 is orally administered twice daily for 14 consecutive days to the patients with recurrent/relapsed or refractory myelodysplastic syndrome, to determine the dose-limiting toxicity and maximum tolerated dose, and to estimate the recommended dose for phase II studies. Pharmacokinetics and antitumor effects will also be investigated.

Read the detailed description

In Cohort 1, SyB C-1101 280 mg/dose group, Participants will be administered 280 mg/dose of SyB C-1101 twice daily orally for 14 consecutive days, followed by 7-day observation period.

In Cohort 2, SyB C-1101 560 mg/dose group, Participants will be administered 560 mg/dose of SyB C-1101 twice daily orally for 14 consecutive days, followed by 7-day observation period.

In both Cohorts, the treatment period of 21 days constitutes 1 cycle, and the treatment was allowed for up to cycles. The participants received SyB C-1101 only once daily on Day 1 and Day 14 of Cycle 1 for the investigation of the pharmacokinetics.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SyB C-1101Drug

    SyB C-1101（rigosertib sodium） will be administered to two cohorts at either 280 mg/day or 560 mg/day.

    The dose will be administered orally twice daily for 14 consecutive days, followed by 7-day observation period. The treatment period of 21 days (14 days of administration + 7 days of observation) constitutes 1 cycle.

    The study will involve treatment through the second cycle, but treatment can be continued for 3 or more cycles if conditions for continued administration are satisfied. However, treatment will be limited to a maximum of 6 cycles including the first cycle.

What is being measured

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

  1. Adverse Events

    Total Number Affected by Any Adverse Event (Details are presented in Adverse Event section)

    Measured: Up to 18 weeks

  2. Number of Participants Who Experienced Dose-limiting Toxicities (DLTs)

    A DLT was defined as adverse events for which a causal relationship with the investigational drug could not be ruled out and which met the following criteria that occurred by the final observation in Cycle 1. DLTs were also assessed in the Efficacy and Safety Assessment Committee.

    Criteria

    1. Grade 3 or higher non-hematologic toxicity. However, nausea, vomiting, diarrhoea, pyrexia, stomatitis, and esophagitis/dysphagia are excluded (Grade 3 nausea, vomiting, diarrhoea, and pyrexia that cannot be controlled with antiemetic, antidiarrheal, or antifebrile agents are regarded as DLTs)
    2. Grade 3 or higher stomatitis, esophagitis, and dysphagia that persist for >= 4 days

    Measured: Up to 21 days

Secondary outcomes (2)

    Any of the following:

    At least 50% decrement from maximum remission/response in granulocytes or platelets Reduction in Hgb by >= 2 g/dL Transfusion dependence

    Measured: Up to 60 weeks

  2. Hematologic Improvement Effect (IWG 2006 Criteria, Responses Must Last at Least 8 Weeks)

    Definition

    Hematologic Improvement Erythrocyte (HI-E):

    Hgb increase by >= 1.5 g/dL Relevant reduction of units of red blood cell (RBC) transfusions by an absolute number of at least 4 RBC transfusions/8 week compared with the pretreatment transfusion number in the previous 8 week. Only RBC transfusions given for a Hgb of <= 9.0 g/dL pretreatment will count in the RBC transfusion response evaluation

    Hematologic Improvement Platelet (HI-P):

    Absolute increase of >= 30×10^9/L for patients starting with > 20×10^9/L platelets Increase from < 20×10^9/L to > 20×10^9/L and by at least 100%

    Hematologic Improvement Neutrophil (HI-N):

    At least 100% increase and an absolute increase > 0.5×10^9/L

    Progressive disease / Relapse:

    At least 1 of the following:

    At least 50% decrement from maximum response levels in granulocytes or platelets Reduction in Hgb by >= 1.5 g/dL Transfusion dependence

    Measured: Up to 18 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SyB C-1101 in people with Myelodysplastic Syndrome, run by SymBio Pharmaceuticals at 4 sites in Japan.

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 28 inclusion and 21 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: finished, as of the sponsor's last update on 21 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Japan. 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 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.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Sep 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Adverse Events (time frame: Up to 18 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02014051.

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 21 Nov 2022.
