This is a Phase I clinical study to evaluate the safety and tolerability, pharmacokinetic characteristics and preliminary efficacy of oral WJ01024 administered as monotherapy and in combination with ruxolitinib in patients with myelofibrosis（MF）. The study will be conducted in two phases: Phase IA and Phase IB.
Phase IA is a dose-escalation and dose-expansion study of WJ01024 monotherapy in patients with MF after failure of JAK inhibitor (JAKi) therapy (relapsed/refractory/intolerant). Phase IB is a dose-escalation and dose-expansion study of WJ01024 in combination with ruxolitinib in JAKi-naïve patients with intermediate- or high-risk MF.
Phase IA is a dose-escalation and dose-expansion study of WJ01024 monotherapy in patients with MF after failure of JAK inhibitor (JAKi) therapy (relapsed/refractory/intolerant).Dose escalation is carried out by combining accelerated titration and the traditional 3+3 design. During the accelerated titration phase, if no dose-limiting toxicity (DLT) and no ≥2 episodes of grade ≥2 treatment-related adverse events (TRAEs) occur within the first cycle (DLT observation period), no further subjects are enrolled at that dose level, and the study proceeds to the traditional 3+3 phase starting with the 60 mg group. At present, it is expected that the dose will be increased in four groups . If the researchers elects to explore intermediate doses or higher doses during the trial, adjustments will be made based on the actual situation. It is planned to expand the dosage by two groups. The final expanded dosage will be determined based on emerging safety and efficacy data. Dose escalation is stratified by background therapy (with vs. without background medication). Phase IB involves dose escalation and dose expansion studies of WJ01024 combined with ruxolitinib. Phase IB is planned to be conducted in JAKi-naïve patients with intermediate- or high-risk MF. Initiation of Phase IB requires that the group in Phase IA has completed the DLT observation period. Two combination dose groups are planned. Intermediate or higher doses may be explored at the investigator's discretion.Two combination dose levels are planned for expansion ;final expansion dose(s) will be determined based on emerging safety and efficacy data.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
