Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Patients received HX301/+Temozolomide treatment at assigned dose level on a 4 weeks basis
Drug: HX301+/Temozolomide
Part I: It is planned to firstly explore a dose of 160 mg and enroll approximately 3-6 subjects to receive HX301 monotherapy until disease progression, intolerable toxicity, or other reasons for stopping treatment for up to 24 cycles of 28 days each. Safety evaluation was performed using the traditional "3 + 3" rule, and the DLT observation period was 28 days (C1D1 ~ C1D28). If 160 mg was not tolerated, it was reduced to 120 mg for exploration. Part II: Combination therapy phase: HX301 will be administered in combination with temozolomide approximately 4-6 weeks after completion of chemoradiotherapy. The TMZ dose will follow the first cycle: 150 mg/m 2 qd D1-D5, starting with the second cycle, and if the criteria for TMZ dose increase are met, TMZ will be administered as 200 mg/m 2 qd D1-D5 every 2 8 days for up to 12 cycles. Monotherapy maintain period: Following the end of temozolomide treatment, HX301 monotherapy will be continued for a maximum of 12 cycles of 28 days each.
