Inclusion criteria
. Male or female subjects aged ≥18 years old;
. Phase I dose escalation period: Histologically or cytologically confirmed diagnosis of locally advanced, or metastatic solid tumor, assessed by investigator that no standard therapy exists, or the tumor has relapsed, progressed or was nonresponsive to available therapies, or intolerance, or not suitable to standard therapy at current stage. Priority will be given to patients who have previously documented NTRK or ROS1 gene fusion confirmed by the central laboratory; Phase I dose expansion and Phase II: Histologically or cytologically confirmed diagnosis of locally advanced, or metastatic solid tumor, patients can provide a written report of pathological diagnosis of NTRK or ROS1 positive tested by qualified laboratory;
. Phase I dose expansion cohort 1 and Phase II cohort 1: locally advanced, or metastatic solid tumor with NTRK gene fusion Phase I dose expansion cohort 2 and Phase II cohort 2： locally advanced, or metastatic NSCLC with ROS1 gene fusion that has progressed to crizotinib and other therapies or was intolerance to crizotinib Phase I dose expansion cohort 3: locally advanced, or metastatic NSCLC with ROS1 gene fusion who have not previously received crizotinib or other therapy.
. phase I dose escalation: at least 1 measurable target lesion according to RECIST version 1.1 Phase I dose expansion and Phase II: at least 1 measurable target lesion according to RECIST version 1.1 (Tumor lesions treated with prior radiation or other local treatment are considered measurable if they show definite progression)
. ECOG PS 0-1
. Life expectancy ≥ 3 months.
. Adequate organ function:
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
Maximum tolerated dose (MTD) (Phase I dose escalation)
Timeframe: 24days following first dose of XZP-5955
2
Number of patients with adverse events (Phase I dose escalation)
Timeframe: within 30 days from last dose
3
Overall Response Rate (ORR) by Blinded Independent Central Review (BICR) (Phase I dose expansion and phase II)
Timeframe: 2 to 3 years after first dose of XZP-5955
. Eligible patients (male and female) who are fertile must agree to at least use a reliable contraceptive method with partner during the trial and within 90 days from the last dose; Women of childbearing age must have a negative serum pregnancy test within 7 days before the first dose of the trial.
Exclusion criteria
. Received anti-tumor therapy such as chemotherapy, radiotherapy, biotherapy, endocrine therapy, immunotherapy or other therapy within 4 weeks prior to the first dose of the investigational drug except the following:
. Received other unmarketed investigational drugs or treatments within 4 weeks prior to the first dose of the investigational drug;
. Major organ surgery (except biopsy) or significant trauma within 4 weeks prior to first dose of the investigational drug or required elective surgery during the trial;
. Adverse reactions to previous antitumor therapy have not recovered to NCI CTCAE 5.0 ≤ grade 1 (except for alopecia, grade 2 peripheral neurotoxicity, stable hypothyroidism after hormone replacement therapy, etc.);
. Inability to swallow drug, or a condition that the investigator judged to severely affect gastrointestinal absorption (eg:Chronic Diarrhea, intestinal obstruction, etc.);
. Cerebral or meningeal metastases with clinical symptoms. The below patients were allowed to be included: those who were asymptomatic, stable, and did not require steroid treatment for more than 4 weeks prior to the start of study treatment (if the cerebral metastases had undergone radiotherapy or/and surgery, radiotherapy and surgery should be at least 1 month prior to the first dose) ;
. Known active infections and currently need intravenous anti-infective therapy;
. History of immune deficiencies, including positive HIV antibody tests;
