This research design for center, increasing openness, dose and dose extension phase I clinical trials, research the main evaluation BAT6005 injection single drug in patients with advanced malignant solid tumors in the safety, tolerability and PK characteristics, to explore the maximum tolerated dose and preliminary antitumor efficacy, provide the basis for subsequent clinical trials recommended dose. Part I: single drug dose escalation study. Part TWO: dose extension study.


Clinical Trial Description

The study is divided into two parts: Part I: single drug dose escalation study. Accelerated titration and "3+3" dose escalation rule were used to explore the safety, tolerability and pharmacokinetic characteristics of BAT6005. Since the clinical benefit of a single agent may be limited, the study used accelerated titration and the "3+3" dose-escalation rule to explore the safe dose range from the ethical point of view of exposing fewer subjects to ineffective doses. Six dose groups were set up, including 10mg (initial dose) group, 30mg group, 100mg group, 300mg group, 600mg group and 900mg group, respectively. The whole is divided into two phases. The first stage: 10mg group, 30mg group, 100mg group using accelerated titration method to increase the dose. The second stage: 300mg group, 600mg group, 900mg group according to the standard "3+3" rule dose increase study. Group/Increasing Method Dose group (mg) Number of fixed dose cases (person) A/ Accelerated titration 10 1, or 3~6 B/ Accelerated titration 30 1, or 3~6 C/ accelerated titration 100 1, or 3~6 D/ Standard 3+3 300 3 to 6 E/ Standard 3+3 600 3 to 6 F/ Standard 3+3 900 3 to 6 Note: After the dose-increasing study is completed, it can be considered as appropriate after comprehensive evaluation of safety and other factors, or a new dose can be selected between the dose that stops climbing and the previous lower dose group according to the above rules to determine the more accurate maximum tolerated dose according to the specific situation and the discussion with the researcher. The dose escalation rules are as follows: For the first 3 dose groups A, B and C, accelerated titration was used in dose-increasing scheme, i.e. cohort size =1. First, 1 subject in group A was included. If no grade ≥2 toxicity was observed related to the study drug (except for simple laboratory abnormalities that the investigator judged to be asymptomatic and without intervention), the subject could be directly transferred to group B for dose escalation, which was accelerated to group C by the rule (" 1+1 "). The accelerated titration dose increase should be discontinued once a class 2 or greater toxicity associated with the drug under study is observed in one group (except for simple laboratory abnormalities that the investigator judged to be asymptomatic and without intervention). An additional 2 subjects in the dose group will be transferred to the standard "3+3" dose escalation (i.e. cohort size =3) mode until MTD or MAD is reached. Starting from group D, the dose increasing mode was adjusted to the standard "3+3" rule, as shown in the following table: DLT population/current dose group population dose increase or decrease decision appears 0/3 3 new subjects received the next high-dose group 1/3 of the current dose group followed by 3 new subjects 1/3 and 0/3 new subjects received the next high-dose group ≥2/3 or ≥2/6 indicates that the dose has exceeded MTD and should be stopped. If there are 6 people in the former dose group, the former lower dose group is used as MTD. If there are only 3 people in the previous dose group, add 3 people to the previous dose group. After the addition of 3 persons, MTD continued to be down-regulated if there were ≥2 DLT in the previous dose group If MTD is found, the sponsor may select a dose of MTD or lower as the recommended dose for phase II clinical studies after discussion with the investigator based on the specific situation. If MTD is not reached, the sponsor may select a dose of MAD or one of the following dose groups as the recommended dose for phase II clinical studies, depending on the specific situation and discussion with the investigator. As the study progresses, protocols may be allowed to revise the definition of DLT as appropriate in light of new clinical findings. Adverse events that meet DLT criteria occurring outside the DLT evaluation period or other adverse safety information that the investigator considers meaningful do not directly influence dose-escalation decisions, but should be taken into account in the final determination of THE RP2D. Prior to each dose increase, the sponsor and investigator will discuss and comprehensively evaluate the decision to increase or decrease the dose, using available information on safety, PK (if any), and efficacy. Prior to inclusion in the next dose team, all subjects in the previous dose group must complete 21 days of DLT observation before toleration is explored according to the standard "3+3" dose escalation rule. In dose-escalation studies, the first subject in the same dose group may be included in the next subject 1 week after the first dose observation. Within each dose group, a minimum of 24 hours should be allowed between the administration of the prior subject and the administration of subsequent subjects. Dose reduction adjustments are not allowed; The dose of BAT6005 should be upregulated as appropriate, but with extreme caution, at least simultaneously: ① Subjects have received at least 4 cycles of study medication; ② After discussion between the sponsor and the study, it was concluded that the subjects receiving the higher primary dose group might bring more clinical benefits than the current dose group; ③ The higher dose group has been shown to fail to reach MTD by subsequent dose escalation studies. Part TWO: dose extension study. According to the preliminary safety and efficacy results of the dose-escalation study, the investigator discussed with the sponsor to select the appropriate dose and tumor species for the extended study, so as to further study the safety and clinical efficacy of BAT6005 single drug, providing a basis for subsequent clinical studies. 1~2 dose cohort studies were planned, with no less than 6 patients in each dose cohort, and PK study was carried out. The overall study period can be roughly divided into screening period, treatment period and follow-up period: Screening period: -28d~0d, that is, after the informed consent is signed, the screening evaluation can be completed within 28 days. Treatment period: Every 3 weeks is one administration cycle, the study drug is given on the first day of each cycle, starting from the second cycle, the time window of administration can be ±3 days, but in addition to imaging examination, subjects must complete vital signs, laboratory examination, physical status score and other tests within 3 days before each administration. Subjects will also be required to complete clinical tumor radiographic evaluations (consistent, CT or MRI) every 6 weeks (±7 days) during the first 24 weeks after initial dosing, and every 9 weeks (±7 days) thereafter. Study drug therapy should continue until the onset of disease progression, withdrawal due to unacceptable toxicity, acceptance of new antitumor therapy due to lack of therapeutic benefit, withdrawal of informed consent and voluntary withdrawal for other reasons, or a maximum of 17 cycles (approximately 1 year), whichever comes first. The DLT evaluation period was defined as the first treatment cycle, from initial dosing to 21 days after dosing. Follow-up Period: If subjects discontinue study drug Therapy, EOT will be considered as the End of Therapy. All subjects, including those who have discontinued treatment for any reason (except loss of follow-up, death, withdrawal of informed consent), will be scheduled for an EOT visit within 21+7 days of receiving their last study drug or prior to receiving subsequent new antitumor therapy. EOT visits should include vital signs, physical examination, laboratory examination, and clinical tumor imaging evaluation (CT or MRI). Safety follow-up: After receiving the last dose of the study drug, subjects were required to be followed up for safety, including immune-related adverse events (irAE), at 21+7, 60 (±7) days, and 90 (±7) days until 90 (±7) days or after receiving new antitumor therapy. Safety visits should be conducted at the study center, where vital signs, physical examination, laboratory examination and other examinations should be performed to evaluate AE, concomitant medication and concomitant treatment until the adverse reactions related to the study drug disappear (or reduce to ≤1). If adverse reactions persist after discontinuation of treatment, the investigator has the discretion to determine the frequency of follow-up based on clinical practice until the investigator believes that the adverse reactions will return to normal, stabilize at an acceptable level, or show no further improvement. Follow-up for survival: After the safe follow-up, the subjects were followed up once every 12 weeks (±14 days) by telephone until death, loss of follow-up, withdrawal of informed consent or termination of the study. The longest treatment time of the drugs studied in this project is about 1 year. If there is no disease progression or intolerance of toxicity after 1 year of initial study use, subjects may return to the study facility for continued use by the investigator. ;
