A Multiple Tumor Species, Open and Multi-center Clinical Study of Alpaloritovorelli Antibodies (QL-1706) Combined with Pulsed Low Dose Rate External Irradiation (PLDR) for Disease Progression After Previous Anti-tumor Therapy

Plain-language summary
For the recurrent and metastatic tumors after first-line treatment (such as lung cancer, esophageal cancer and cervical cancer), the risk of conventional fractionated secondary radiotherapy is high because the tumor is close to the hollow organs (such as heart, lung and small intestine). According to previous studies, combined chemotherapy regimens are often used, but the disease control rate (DCR) is limited, and drug resistance and poor tolerance of patients are prone to occur. The immune checkpoint inhibitors (ICB) has been considered as a new strategy for maintenance treatment of patients with recurrent and metastatic tumors, but only some patients can respond for a long time. Therefore, how to improve the clinical response rate of ICB has become an urgent problem to be solved. Pulsed low dose rate radiotherapy (PLDR), a new radiotherapy technology emerging in recent years, is expected to become a new way to solve the above difficulties. Alpaloritovorelli antibodies (QL-1706) is a new type of combination antibody independently developed by Qilu Pharmaceutical Co., Ltd. It is composed of IgG4 antibody targeting PD-1 (ipalorimab), and IgG1 antibody targeting CTLA-4 (tuvonralimab) in a fixed proportion. It has the synergistic mechanism of blocking PD-1 and CTLA-4 at the same time. The combination of these two antibodies forms a powerful synergistic effect and forms positive feedback in the tumor immune cycle.
Pulsed low dose rate radiotherapy (PLDR) is a safe and feasible option for recurrent tumors with high risk of re-radiotherapy. It also has therapeutic advantages for refractory and massive tumors. The advantages of combined vascular targeting and chemotherapy have been initially demonstrated. As a new anti-tumor therapy, immunotherapy has shown clinical benefits in many types of cancer, but the overall effective rate is still limited, which may be due to the immune "desertification" of the tumor microenvironment. PLDR irradiation is expected to reverse the tumor inhibitory microenvironment by inducing the release of tumor associated antigen and increasing the killing function of T cells, activate tumor immunity and improve the response rate of immunotherapy. Based on this, this study plans to take the lead in carrying out this prospective clinical study through the combination of PLDR external irradiation and ICB treatment (QL-1706).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
