Receives: Drug: TQ05105 Tablets; Drug: TQB3617 Capsules

What is being measured

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

  1. Maximal tolerance dose (MTD)

    If dose limiting toxicity (DLT) occurs in 2 or more subjects in a given dose group, the dose level in the previous dose group is considered MTD.

    Measured: Up to 2 years.

  2. Recommended phase II dose (RP2D)

    The RP2D is defined as the lower dose level to MTD based on the safety profile.

    Measured: Up to 2 years

  3. ≥35% reduction in spleen volume (SVR35)

    The proportion of subjects with a ≥35% reduction in spleen volume from baseline at the end of treatment at week 24.

    Measured: Up to 24 weeks

Secondary outcomes (14)
  1. SVR35

    The proportion of subjects with a ≥35% reduction in spleen volume compared to baseline after treatment.

    Measured: Up to 120 weeks

  2. Optimum effective rate

    The proportion of subjects with at least once spleen volume reduction ≥ 35% from baseline.

    Measured: Up to 120 weeks

  3. Onset time of splenic response

    The time interval from the first administration to the date when the spleen volume was reduced by ≥ 35 % from baseline.

    Measured: Up to 120 weeks

  4. Duration of maintenance of at least 35% Reduction in Spleen Volume (DoMSR)

    The time between the date when the spleen volume reduction ≥ 35% from baseline occurs for the first time and the date when the spleen volume reduction is < 35% from baseline.

    Measured: Up to 120 weeks

  5. Myeloproliferative neoplasm - Symptom Assessment Form - Total Symptom Score (MPN-SAF TSS)

    The proportion of subjects whose total symptom score of MPN-SAF TSS decreased by more than 50% from baseline. MPN-SAF-TSS is an effective tool for evaluating the disease burden of patients with myeloproliferative neoplasms. Each symptom is scored according to the severity, from asymptomatic (0 points) to the most serious (10 points), a total of 10 levels, the sum of 10 symptom scores is MPN-SAF-TSS score. The higher the score, the more severe the symptoms are.

    Measured: Up to 60 weeks

  6. MPN-SAF TSS change

    The total score of MPN-SAF TSS decreased compared with baseline. MPN-SAF-TSS is an effective tool for evaluating the disease burden of patients with myeloproliferative neoplasms. Each symptom is scored according to the severity, from asymptomatic (0 points) to the most serious (10 points), a total of 10 levels, the sum of 10 symptom scores is MPN-SAF-TSS score. The higher the score, the more severe the symptoms are.

    Measured: Up to 120 weeks

  7. Variant allele frequency (VAF)

    The proportion of subjects whose VAF decreased compared with baseline.

    Measured: Up to 48 weeks

  8. The proportion of subjects with gene mutation achieving SVR35

    The proportion of subjects with gene mutation achieving SVR35

    Measured: Up to 48 weeks

  9. The proportion of subjects with gene mutation whose MPN-SAF TSS scale decreased by ≥ 50%

    The proportion of subjects with gene mutation whose MPN-SAF TSS scale decreased by ≥ 50% compared with baseline.

    Measured: Up to 48 weeks.

  10. Progression-free survival (PFS)

    The time interval from the first dose to the date of the occurrence of any of the following events, whichever occurs first:(1) Spleen volume increased by ≥25% compared with the screening period ; (2) Death caused by any cause.

    Measured: Up to 120 weeks

  11. Leukemia free survival (LFS)

    The time interval from the date of the first dose to the date of any of the following events, whichever occurs first: (1) the date of the first bone marrow smear showing the original cell ≥20% ;(2) The first peripheral blood smear showed that the original cells ≥ 20% and the absolute value of the original cells ≥1×10^9/L and lasted for at least 2 weeks; (3) Death caused by any reason.

    Measured: Up to 120 weeks

  12. Overall Survival (OS)

    OS is defined as the time from the first time the subject received treatment to death due to any cause.

    Measured: Up to 120 weeks

  13. Incidence of adverse events (AEs)

    Incidence rate of all adverse medical events that occur after the subject receives the investigational drug, evaluated according to the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0)

    Measured: Baseline up to 120 weeks

  14. Severity of adverse events (AEs)

    Severity of all adverse medical events that occur after the subject receives the investigational drug, evaluated according to the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0)

    Measured: Baseline up to 120 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TQ05105 Tablets and TQB3617 Capsules in people with Myelofibrosis, run by Chia Tai Tianqing Pharmaceutical Group Co., Ltd. at 22 sites 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 12 inclusion and 25 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: looking for participants now, as of the sponsor's last update on 8 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Chunkang Chang, Doctor (13764643870, changchunkang7010@aliyun.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximal tolerance dose (MTD) (time frame: Up to 2 years.). The study lists 3 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 8 Dec 2025.
