What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study follows about 40 people with intermediate or high-risk myelofibrosis who are already taking gecacitinib. Researchers will collect bone marrow and blood samples each year to see how the disease and gene mutations change over time. No new drugs are given—this is an observation-only study to understand long-term effects.

Who is studied

This study was an observational study, and about 40 patients with intermediate and high risk myelofibrosis who had participated in any previous clinical study of Gecacitinib hydrochloride and were still receiving Gecacitinib treatment in our center were expected to be enrolled. There was no additional drug intervention, only the myelofibrosis grade and gene mutation level of the patients were collected. Subjects who met all inclusion criteria and none of the exclusion criteria were eligible for inclusion in this study.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Inclusion Criteria: * They had been enrolled in previous clinical trials of gefitinib for myelofibrosis (ZGJAK002, ZGJAK006, ZGJAK016 and ZGJAK017) and were still receiving gefitinib treatment. * Comply with the requirements of the ethics committee, voluntarily sign the informed consent. * Able to adhere to study and follow-up procedures. Exclusion Criteria: * Patients with other serious diseases that the researcher believes may affect patient compliance and outcome observation.
