About this study
Official title: Phase II Study of Cadonilimab Combined With Bevacizumab and Chemotherapy for Advanced Nonsquamous Non-small Cell Lung Cancer Patients With Untreated Brain Metastases
The purpose of this study was to investigate the efficacy and safety of Cadonilimab combined with bevacizumab and chemotherapy for advanced non-squamous NSCLC with untreated brain metastases. Cadonilimab is a bispecific antibody (BsAb), which can bind PD-1 and CTLA-4 at the same time with high affinity. It is a new tumor immunotherapy drug with tetravalent structure and short half-life. It has shown less toxicity than anti-PD-1 and anti-CTLA-4 antibodies in monkey toxicity studies. These characteristics make the application of Cadonilimab in tumor subjects may have better efficacy and safety.
AK104-207 is an open, multicenter, phase Ib/II clinical study, which aims to evaluate the effectiveness and safety of Cadonilimab combined with chemotherapy as the first-line treatment for locally advanced or metastatic non-small cell lung cancer that cannot be operated and cannot receive radical concurrent/sequential radiotherapy and chemotherapy. As of August 1, 2022, 19 subjects who can evaluate non-squamous NSCLC (cohort B), ORR is 63.2%, DCR is 100%, median PFS is 13.34 months (7.36, NE), median OS is not reached, and 12-month OS rate is 76.0% (95% CI 48.0-90.3). In PD-L1 positive patients (n=9), ORR was 55.6% and DCR was 100%. In PD-L1 negative patients (n=7), ORR was 85.7% and DCR was 100%.
In view of the early curative effect of Cadonilimab in NSCLC single drug or combination therapy and the encouraging research results of PD-1 inhibitor combined with CTLA-4 double immune combination therapy, it is expected that Cadonilimab combined with bevacizumab and chemotherapy will achieve good curative effect in NSCLC patients with brain metastasis.

Study Name:
Phase II study of Cadonilimab combined with bevacizumab and chemotherapy for advanced nonsquamous non-small cell lung cancer patients with untreated brain metastases Purpose of research MAIN OBJECTIVE: Total response rate (ORR) Secondary purposes: progression-free survival (PFS), intracranial PFS (iPFS), overall survival (OS), Quality of Life (QoL) and safety Exploratory Objective: To explore the potential evolutionary mechanism of brain metastasis of lung cancer and the difference of immune microenvironment between primary focus and metastatic focus.
Design type: Intervention research Subjects: Non-squamous NSCLC in advanced stage of untreated brain metastasis Sample size: 36 cases Statistical analysis method: This cohort was a one-arm test, using Simon-Minimax two-stage design, assuming that the ORR rate was 20% under the ineffective hypothesis and 40% under the hypothesis that the drug was considered effective. The degree of assurance is 0.8, the test level α is set to 0.05, and the sample size estimation result is a total sample of 33 cases. Eighteen subjects who meet the admission criteria are planned to be enrolled first. If 4 patients have CR or PR, they will continue to be enrolled until 33 patients are reached. Only when more than 10 patients in the total sample reach CR or PR can the study reach the main endpoint. Considering the shedding rate of 10%, the sample size of this study is estimated to be 36 cases. Data were collected from the first day of treatment to the death of the patient or the last follow-up. All rate estimates were evaluated by Kaplan-Meier model (SPSS, version 25.0). Univariate analysis and multivariate analysis of Cox regression model were used to analyze the related factors of prognosis. long-rank test was used to compare the difference of observation endpoint. P < 0.05 was statistically significant.
Screening period: Subjects will complete screening evaluation within 28 days before the first medication to determine whether they meet the research conditions. During the screening period, the peripheral blood of the subjects should be collected.
Treatment period: The subjects who met the conditions of the study population were treated with Cadonilimab 10mg/kg + bevacizumab 7.5 mg/kg + carboplatin (AUC 5) + pemetrexed 500mg/m2. Every 3 weeks is a cycle, with a total of 4-6 cycles (the number of chemotherapy cycles is determined by the researchers). Cadonilimab 10mg/kg, bevacizumab 7.5 mg/kg and pemetrexed 500mg/m2 were then maintained until disease progression, intolerable toxicity or other causes specified in the regimen occurred. When the subject first has imaging disease progression, if the researcher judges that it is clinically beneficial and tolerant to the test drug, he will be allowed to continue treatment.
During the treatment, the researchers evaluated the curative effect according to RECIST 1.1 standard. ORR evaluated by researchers was used as the main curative effect index. Subjects were evaluated for tumor every 6 weeks (7 days) within 54 weeks after enrollment, and every 12 weeks (7 days) after enrollment. Subjects who stop taking drugs for non-disease progression reasons will continue to follow up their disease status until the subjects start other anti-tumor treatment, disease progression, withdrawal of consent, death or end of study, whichever occurs first.
During the treatment, researchers will collect a series of blood samples for pharmacokinetics, immunogenicity and exploratory research and analysis.
Adverse events (AE) of each subject will be collected until 30 days after the last administration or new anti-tumor treatment will be started, whichever occurs first. Serious adverse events (SAE) will be collected until 90 days after the last administration or new anti-tumor treatment will be started, whichever occurs first. Immune-related AE (irAE) will be collected until 90 days after the last administration or new anti-tumor therapy will be started, whichever occurs first. Survival assessment was performed every 3 months after the last dose to obtain survival information and collect information on subsequent anti-tumor treatment after termination of study treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Cadonilimab in people with Non Small Cell Lung Cancer and Brain Metastases, run by Second Affiliated Hospital of Nanchang University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Anwen Liu, PhD (+8613767120022, awliu666@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
overall response rate (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2023.
