Summary

Overall Design: This is a phase I, open-label, multicenter clinical study to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-cancer efficacy of ABM-1310 in patients with BRAF V600-mutant relapsed and drug resistant primary malignant brain tumors. The study including four periods of screening (28 days), treatment (no more than 2 years), safety follow-up and survival follow-up. This study consists of two stages: dose escalation and dose expansion. During the dose escalation stage, a classic "3+3" design will be used to guide dose escalation to determine MTD and RP2D. Three to six subjects are expected to be enrolled in each dose group and at least 6 subjects are enrolled in the MTD/highest dose group. The total number of subjects enrolled during the dose escalation stage will depend on the amount of DLT and the total number of dose levels explored. If DLT is not observed in the first 3 subjects enrolled for each dose level, the Safety Monitoring Committee (SMC, including investigators, pharmacologists, and the sponsor's medical specialists, and other experienced members specially invited as necessary) will review the cumulative safety data of subjects at each dose level and decide whether to proceed with dose escalation upon the completion of study treatment at least for the DLT evaluation period (28 days of Cycle 1). The dose expansion stage in this study will be initiated at the MTD or the optimal dose determined by the SMC as a fixed dose level (MTD or the optimal dose needs to be reviewed by the SMC and subjects are safe and tolerable at that dose level). The dose expansion stage is expected to include the following two cohorts of relapsed and drug resistant primary malignant brain tumors with BRAF V600 mutations:Cohort 1: GBM, N = up to 25 patients; Cohort 2: In addition to GBM, other primary malignant brain tumors, N = up to 15 patients. In this study, the corresponding sample size for each cohort/tumor type may be determined according to the actual efficacy and safety data obtained. After each cohort included the first 10 patients, the available safety, efficacy, and PK data were analyzed. Based on the analysis results, the sponsor decided whether to continue recruiting patients for the study.

Inclusion Criteria

•1. Subjects who are able to understand and voluntarily sign informed consent forms (ICFs).
•2. Male and female subjects at the age of ≥18 at the time of screening.
•3. Patients with histologically or cytologically-confirmed, primary malignant brain tumor with (a) failure of prior standard therapy, (b) no standard therapy available, or (c) for whom standard therapy is not applicable considered by the patient or treating physician, or (d) intolerance to standard treatment. Subjects who were previously treated with BRAF and/or MEK inhibitors are allowed to be enrolled in this study.
•4. Documentation of positive BRAF V600 mutation is required for enrollment. It is recommended to provide sufficient fresh/archived tumor tissue samples (formalin-fixed paraffin-embedded tumor specimens \[preferred\]) or 5-10 available unstained sections of good quality for verification of BRAF V600 mutation status at the central laboratory. For any subject who is unable to provide suitable and adequate tumor specimens, re-biopsy (with controllable safety) can be performed in a non-mandatory manner if it is feasible as assessed by the investigator and the subject gives informed consent; if re-biopsy is impossible or refused by the subject, his/her eligibility for enrollment shall be confirmed by both the investigator and the sponsor.
•5. Patients with primary malignant brain tumors that are asymptomatic, or that are symptomatic but on a stable or decreasing dose of steroids for at least 2 weeks are eligible for enrollment. The specific criteria are as follows:Subjects with inactive and asymptomatic primary malignant brain tumors;Subjects who have active, mild neurological signs and symptoms currently requiring no therapy with steroids, and have no history of epileptic seizure within 2 weeks prior to initiation of treatment;Subjects who have active, neurological signs and symptoms and were on a stable or gradually reducing dose up to 5 mg of dexamethasone (or equivalent) per day within 2 weeks prior to initiation of treatment;
•6. Antitumor efficacy was evaluated using the RANO criteria, which required the presence of at least one measurable lesion (the diameters that are perpendicular to each other are not less than 10 mm). Lesions previously treated with radiotherapy shall not be deemed as target lesions unless significant progression as shown on imaging.
•7. Karnofsky PS score of ≥ 60.
•8. Survival expectancy ≥ 3 months.
•9. Adequate organ function (no blood transfusion and no use of granulocyte colony-stimulating factor, or other hematopoietic stimulator support within 2 weeks before the first administration of the study drug) confirmed as evidenced by:Absolute Neutrophil Count (ANC) ≥ 1.5×10\^9/L;Hemoglobin (Hgb) ≥ 90 g/dl;Platelets (Plt) ≥ 75×10\^9/L;AST/ALT ≤ 2.5 x ULN or ≤ 5.0 x ULN if liver metastases are present;Bilirubin total ≤ 1.5 x ULN, or bilirubin direct \< ULN for patients with bilirubin total levels \>1.5 ULN;Serum creatinine \< 1.5 x ULN or creatinine clearance \> 50 mL/min (as calculated via Cockcroft-Gault formula based on the actual body weight of the subject;International normalized ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5 x ULN for subjects not receiving anticoagulant therapy, and INR is maintained within the standard range of treatment prior to starting study drug for subjects receiving anticoagulant therapy.
•10. Hepatitis B virus surface antigen (HBsAg) is negative, or HBsAg is positive but HBV DNA titer is below the lower limit of positive detection of the participating site at screening.HBsAg-positive or HBV-DNA positive subjects shall be managed according to institutional guidelines (anti-HBV therapy, where appropriate, and close monitoring of liver function and HBV-DNA replication shall be performed).

Exclusion Criteria

•1. Women who are pregnant or breast-feeding.
•2. Subjects with history of neoplasm malignant (except for primary malignant brain tumors) within 5 years prior to screening, excluding cured carcinoma in situ of cervix, non-melanoma skin cancer, localized prostate cancer and other tumors/cancers that have undergone radical treatment and shown no signs of disease for at least 3 years (This exclusion criterion is only applicable for dose expansion stage). For the dose escalation stage, any patient with double primary malignant solid tumors who can indeed benefit from this study as confirmed by the investigator is eligible for the screening.
•3. Subjects with intracranial hypertension or associated risks (e.g., intracranial infection, intracranial hemorrhage) to be controlled.
