Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Percentage of subjects with >=35% reduction in spleen volume from baseline
. Splenomegaly: Palpation of the splenic margin reaching or exceeding 5cm below the rib (distance from the intersection of the left clavicle midline and left rib margin to the farthest point of the spleen); Or due to physical reasons (such as obesity), it may not be palpable, but MRI/CT spleen evaluation during screening confirms a volume of \>= 450 cm\^3;
. Peripheral blood and bone marrow blasts \<=10%;
Exclusion criteria
. The toxic reactions of previous anti-cancer treatments have not recovered to grade 1 or below (excluding hair loss), or have not fully recovered from previous surgeries(such as undergoing major surgery within 4 weeks);
. Allergy to experimental drugs and their excipients;
. For any significant clinical and laboratory abnormalities, the researchers believe that they affect the safety evaluators, such as: a. uncontrollable diabetes - fasting blood glucose\>250 mg/dL (13.9 mmol/L), b. hypertension and cannot be reduced to the following range after treatment with two or more antihypertensive drugs (systolic blood pressure\<160 mmHg, diastolic blood pressure\<100 mmHg), c. peripheral neuropathy;
. Patients with a history of congestive heart failure (NYHA grade III or above), unstable angina or myocardial infarction, cerebrovascular accidents or thromboembolism within the first 6 months of screening;
. Individuals with impaired cardiac function (those with ejection fraction\<45% detected by echocardiography, congenital ventricular arrhythmia, QTcF\>450 ms on electrocardiogram (males), QTcF\>470 ms on electrocardiogram (females), or those with arrhythmia requiring treatment at the time of screening);
. Patients with congenital or acquired bleeding disorders or unstable thrombotic diseases requiring anticoagulant therapy;
. Any active infections requiring systemic treatment (oral, intravenous, subcutaneous, intramuscular, etc.) within 14 days prior to enrollment;
. Individuals who have experienced active tuberculosis infection within the 48 weeks prior to screening or those who have been diagnosed with latent tuberculosis infection during the screening period (those diagnosed with latent tuberculosis infection must complete preventive anti tuberculosis treatment for at least 3 months before they can be enrolled);
