About this study

Official title: A Multicenter, Open-Label Phase I/IIa Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics/ Pharmacodynamics and Efficacy of BR1733 Monotherapy in Subjects With Advanced Cancers

This study is a Phase I/IIa, multi-center, open-label study of BR1733 with a dose escalation part followed by a dose expansion part in adult subjects with advanced cancers.

This treatment to characterize the safety, tolerability, PK, PD and preliminary antitumor activity.

The study treatment will be administered until the subject experiences unacceptable toxicity, progressive disease, and/or has treatment discontinued at the discretion of the Investigator or the subject, or due to withdrawal of consent.

Read the detailed description

This is a multi-center, nonrandomized, open-label study to evaluate the safety, tolerability, pharmacokinetics/ pharmacodynamics, and efficacy of BR1733 in patients with advance cancer, such as recurrent/refractory follicular lymphoma, peripheral T cell lymphoma(PTCL), diffuse large B cell lymphoma(DLBCL) and advance solid tumors.

Phase Ⅰ (Dose Escalation Phase): According to the incidence of DLT in BR1733 tablets in the treatment of advanced cancers, MTD and the Phase 2 clinical trial dose (RP2D) combining PK, PD, efficacy and safety data were determined.

Phase IIa (Dose expansion stage): Evaluate the efficacy and safety of BR1733 monotherapy (Cohorts 1-5) in five separate cohorts.

What is being measured

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

  1. Dose Limiting Toxicity (DLT, Phase Ⅰ only)

    To assess adverse events as dose limiting toxicities as defined by the protocol.

    Measured: 28 day cycle of therapy

  2. Objective Response Rate (ORR, Phase Ⅱa)

    The proportion of patients with a best response of at least partial remission (including partial remission and complete remission) using disease appropriate standardized response criteria.

    Measured: 24 months

Secondary outcomes (10)
  1. Halflife (T1/2) of BR1733 monotherapy

    Pharmacokinetics profile of BR1733 (plasma): Halflife (T1/2)

    Measured: 28 day cycle of therapy

  2. Area under curve (AUC) of BR1733 monotherapy

    Pharmacokinetics profile of BR1733 (plasma): Area under curve (AUC)

    Measured: 28 day cycle of therapy

  3. Maximum plasma concentration (Cmax) of BR1733 monotherapy

    Pharmacokinetics profile of BR1733 (plasma): Maximum plasma concentration (Cmax)

    Measured: 28 day cycle of therapy

  4. Area under curve, steady state (AUCss) of BR1733 monotherapy

    Pharmacokinetics profile of continuous medication of BR1733 (plasma): Area under curve, steady state (AUCss)

    Measured: 28 day cycle of therapy

  5. Maximum plasma concentration, steady state (Cmax,ss) of BR1733 monotherapy

    Pharmacokinetics profile of continuous medication of BR1733 (plasma):

    Maximum plasma concentration, steady state (Cmax,ss)

    Measured: 28 day cycle of therapy

  6. Clearance/ bioavailability (CL/F) of BR1733 monotherapy

    Pharmacokinetics profile of BR1733 (plasma): Clearance/bioavailability (CL/F)

    Measured: 28 day cycle of therapy

  7. Incidence and Severity of Adverse Events as a Measure of Safety and Tolerability

    Adverse events assessed according to NCI-CTCAE v5.0 criteria.

    Measured: Up to 2 years

  8. Duration of Response (DoR)

    DoR is defined as the duration (days) from initial response to disease relapse, progression, or death due to any course.

    Measured: Up to 2 years

  9. Overall Survival (OS)

    OS is defined as the interval of time between the date of first treatment until death, loss to follow up or termination of the study by the sponsor

    Measured: Up to 2 years

  10. Progression-free survival (PFS)

    PFS is defined as the interval of time between the date of first treatment to the earliest date of disease progression or death which occurs first

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BR1733 in people with Advanced Cancer and Follicular Lymphoma, run by Shanghai Blueray Biopharma Co., Ltd. at 1 site in China.

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 5 inclusion and 10 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 7 Aug 2024. 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 China. 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?

Dose Limiting Toxicity (DLT, Phase Ⅰ only) (time frame: 28 day cycle of therapy). 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?
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 7 Aug 2024.
