About
BMD006 is an inhaled mRNA tumor-associated antigen dry powder vaccine targeting lung cancer and solid tumors with lung metastasis, classified as an off-the-shelf anti-tumor product. The product contains two clinically validated TAA antigen combinations: for patients with solid tumors that have lung metastasis, the mRNA vaccine consists of four mRNA sequences encoding melanoma-associated tumor antigens ; for patients with primary lung cancer, the mRNA vaccine consists of six mRNA sequences encoding tumor-associated antigens of primary lung cancer .
This study is a single-center, open-label, dose-escalation trial designed to evaluate the safety, tolerability, preliminary efficacy, PK, and PD of BMD006 in patients with advanced lung cancer or advanced solid tumors with lung metastasis who have failed standard treatments or have no standard treatment options. Additionally, the study will further explore the effect of BMD006 in combination with PD-1 treatment.
Full description
BMD006 is an inhaled mRNA tumor-associated antigen dry powder vaccine targeting lung cancer and solid tumors with lung metastasis, classified as an off-the-shelf anti-tumor product. The product contains two clinically validated TAA antigen combinations: for patients with solid tumors that have lung metastasis, the mRNA vaccine consists of four mRNA sequences encoding melanoma-associated tumor antigens ; for patients with primary lung cancer, the mRNA vaccine consists of six mRNA sequences encoding tumor-associated antigens of primary lung cancer .
This study is a single-center, open-label, dose-escalation trial designed to evaluate the safety, tolerability, preliminary efficacy, PK, and PD of BMD006 in patients with advanced lung cancer or advanced solid tumors with lung metastasis who have failed standard treatments or have no standard treatment options. Additionally, the study will further explore the effect of BMD006 in combination with PD-1 treatment.
In Part 1, the trial plans to enroll approximately 16-31 patients and perform dose escalation in 6 dose groups, including BMD006 50 μ g, 100 μ g, 200 μ g, 400 μ g, 800 μ g, and 1200 μ g.After receiving the first treatment with BMD006 on D1, the patient completed a single treatment DLT observation (14 days) and was evaluated by the researchers to be safe and tolerable.They will enter multiple treatment DLT observation (14 days) and receive BMD006 treatment on D15 and D22, respectively. On D28, the patient will continue to receive QW treatment at the current dose level for 6 times, and then switch to Q3W treatment from the 11th week until 52 weeks after the first treatment or until the termination criteria are met (defined as: disease progression, intolerable toxicity, withdrawal of informed consent, loss to follow-up, death, or end of the study, whichever occurs first). At the same time as the patient enters the treatment period, the next dose group of patients will be initiated for single treatment and observation.
Considering the high safety of starting dose selection (1/20 of the human safety dose inferred from preclinical research data), the 50 μ g group will adopt the method of accelerated titration, and one patient is planned to be enrolled.
During the process of accelerated titration, if there are ≥ 2 levels of adverse events (TRAE) related to investigational product after treatment during the observation period of DLT, two more patients will be added at the current dose level, and the "3+3" mode will be changed from then on.
During the dose escalation process, the investigator can decide whether to add additional dose levels based on the patient's safety evaluation results, as well as PK, PD, biomarker, and other test results (if available), to better explore the risks and benefits of the patient's exposure to the investigational product.
After treatment, safety follow-up and long-term follow-up will be carried out for each patient according to the time specified in the protocol. All patients will receive remote follow-up (by phone, etc.) to assess the overall survival until 2 years after the first treatment or the end point of long-term follow-up (defined as withdrawal of informed consent, withdrawal from the study, loss to follow-up, death or the end of the study, whichever occurs first).
During the study, sample collection and safety assessment of PK, PD and biomarkers will be conducted at the corresponding visit points. Tumor evaluation was performed by the investigator according to RECIST v1.1. Imaging examination was performed every 6 weeks 6 months after the first treatment, and every 9 weeks 6 months later until 2 years after the first treatment or the end point of long-term follow-up.
When the dose escalation of Part 1 is completed and the MTD level ( RP2D of this study) is determined, the dose escalation exploration of BMD006 combined with PD-1 antibody will be carried out.
The dose of BMD006 is explored starting from the previous dose of RP2D, and the next dose was explored to RP2D. According to the "3+3" model, 3-6 patients were enrolled in each dose. The patient will receive BMD006 combined with PD-1 antibody treatment on D1, and BMD006 treatment on D8 and D15. The DLT observation period is 21 days. D21 is safe and tolerable according to the investigator's assessment. The patient will continue to be treated according to QW regimen for 6 times at the current dose level, and then change to q3w treatment from the 10th week until 52 weeks after the first treatment or reaching the standard of termination. During the study, patients will receive fixed dose treatment with PD-1 antibody until 52 weeks after the first treatment or reaching the standard of termination of treatment. When the patient enters the treatment period, the treatment and observation of patients in the next dose group will be started.
