About

Phase IIa study of HX009+ IN10018 in combination with or without standard chemotherapy in patients with advanced solid tumours including biliary tract malignancies and malignant melanoma

Full description

The Part1 safety run-in stage:

About 6~24 patients are expected to be enrolled in the safety run-in stage, 3~6 cases will be enrolled first in the 7.5mg/kg dose group, and if the 7.5mg/kg dose level is tolerable, then 3~6 cases will continue to be enrolled up to the 10mg/kg dose group; if the 7.5mg/kg dose group can not be tolerated, it will be decided whether to add a new lower dose level after discussion between the sponsor and the investigators, based on the '3+3' rule, which determines the actual number of cases enrolled, the number of replacement subjects, and the number of dose groups to be explored for each cohort based on observed safety data.

Part I Phase IIa stage:

Based on data from safety run-in stage , a target ORR of 20% for HX009 in combination with IN10018 in patients with treated advanced biliary cancers was pre-set, and a total of 20-30 subjects were planned to be enrolled at the appropriate recommended dose level, and HX009 in combination with IN10018 for the treatment of patients with advanced biliary malignancies was considered to be a treatment option for HX009 in combination with IN10018 if the best efficacy was observed as a CR or a PR in at least 5 subjects. patients with advanced biliary malignancies, supporting further exploratory studies.

Exclusion criteria

Patients with melanoma with known BRAF v600E mutation and NRAS mutation; patients with cholangiocarcinoma and gallbladder cancer with known BRAF v600E mutation, NTRK gene fusion, RET gene fusion mutation, FGFR2 gene fusion, IDH1 gene mutation, and KRAS mutation
Subjects with symptomatic brain metastases, meningeal metastases, or spinal cord compression, except for the following: asymptomatic brain metastases (i.e., no progressive central nervous system symptoms caused by brain metastases, no need for corticosteroid or antiepileptic drugs, and the lesion has been stable for ≥4 weeks as confirmed by imaging tests);
have had a malignancy other than the study disease (biliary malignancy, malignant melanoma) within 5 years prior to signing the ICF, except for malignancies with negligible risk of metastasis or death and/or those that have received curative treatment (e.g. adequately treated cervical carcinoma in situ, basal or squamous cell skin carcinoma, confined prostate cancer, ductal carcinoma in situ, or stage I uterine cancer);

However, subjects with the following diseases were allowed to enrol:
- Type 1 diabetes mellitus that has stabilised with the use of fixed doses of insulin;
- Autoimmune hypothyroidism and adrenal insufficiency requiring only hormone replacement therapy;
- Skin diseases that do not require systemic therapy: e.g. eczema, rashes that cover less than 10 per cent of the body surface, psoriasis without ocular symptoms.
have severe cardiovascular disease such as symptomatic congestive heart failure (New York Heart Association Class III or IV), unstable angina, uncontrolled hypertension (systolic blood pressure ≥160 and/or diastolic blood pressure ≥100 mmHg under pharmacological control), cardiac arrhythmia, history of myocardial infarction within 6 months, or history of arterial thromboembolism or pulmonary embolism within 3 months prior to the first administration of the drug
suffering from a serious lung disease requiring treatment or previous serious lung disease, interstitial lung disease, interstitial pneumonitis, pulmonary fibrosis, radiation pneumonitis requiring hormonal therapy, etc;
uncontrolled concomitant medical conditions including, but not limited to, severe diabetes mellitus (fasting blood glucose > 250 mg/dl or 13.9 mmol/L), active infectious diseases, psychiatric disorders (e.g., epilepsy) that may interfere with adherence, or other serious conditions requiring systemic therapy
patient with uncontrolled pleural effusions, abdominal effusions or pericardial effusions that require repeated drainage. Individuals with indwelling drains are permitted to be enrolled;
