一项随机II期研究:评估无症状活动性脑转移NSCLC患者中先行对所有脑转移灶进行立体定向放疗后接续伊沃西单抗联合化疗与先行伊沃西单抗联合化疗的疗效对比
一项评估无症状活动性脑转移非小细胞肺癌患者全脑转移灶先行立体定向放疗后接续伊沃塞单抗联合化疗对比先行伊沃塞单抗联合化疗的随机II期研究
这是一项随机、双臂、对照的II期临床试验,旨在评估两种治疗策略之间颅内无进展生存期(iPFS)的差异,由当地进行评估。
约158名患者将按1:1比例随机分组。纳入标准为经病理证实的转移性非小细胞肺癌患者,其无可操作的基因组改变且存在一线靶向治疗可用,并伴有活动性无症状脑转移(新诊断或进展性)。
主要目的是比较两组间的iPFS。

Main inclusion criteria
- Age 18 years or older
- ECOG PS < 2
- Patients with pathology proven metastatic NSCLC without an actionable genomic alteration for which there is first line targeted treatment approved by EMA and recommended by the ESMO guidelines.
- Asymptomatic or minimally symptomatic brain metastases defined as requiring a dose of steroids of maximum 4 mg equivalent dexamethasone per day for the last 7 days to control neurological symptoms. With the clinically oligosymptomatic further defined as having no indication for immediate localized brain therapy, including neurosurgery or radiotherapy. Patients with controlled seizures can be enrolled.
- Newly diagnosed brain metastasis with the following characteristics:
- 1-10 newly diagnosed and untreated (except resected) brain metastases. Note: if the neuronavigation MRI in the upfront SRS/FSRT arms shows > 10 metastases and if the total volume is deemed safe to be treated, but the MRI used for enrolment showed 1-10 metastases the patient will be still considered eligible.
- At least one metastasis should be at least 5x5 mm. In case of doubt on the diagnosis of brain metastasis, the lesion should not be irradiated but followed up.
- The largest metastasis must be estimated <10 mL in volume and <30 mm in longest diameter (resected lesions would not count).
- The maximum cumulative volume of brain metastases must be estimated <30 mL (resected lesions would not count).
- Candidate for stereotactic radiosurgery/therapy (SRS/FSRT) of BM and systemic treatment (preferably discussed in an MDT)

- Before patient 's enrolment, written informed consent must be given according to ICH/GCP, and national/local regulations.
Main exclusion criteria
- Patients with oligometastatic NSCLC who are scheduled to receive radical local treatment to extra-cranial sites.
- Active auto-immune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

实验性的:测序组
患者将在随机分组后≤14天内接受所有脑转移灶的立体定向放射治疗/分次立体定向放射治疗,随后接受4个周期铂类化疗联合ivonescimab(20 mg/kg,每3周一次)治疗。全身治疗后将继续使用ivonescimab(20 mg/kg)联合培美曲塞(仅适用于非鳞状非小细胞肺癌患者)进行维持治疗,每3周一次,最长持续2年。

ivonescimab iv at 20 mg/kg every 3 weeks
For adenocarcinoma : Carboplatin area under the curve of 5 mg/mL/min (AUC 5) IV with pemetrexed 500 mg/m2 IV on day 1 every 21 days (Q3W) for 4 cycles
For adenocarcinoma : Carboplatin area under the curve of 5 mg/mL/min (AUC 5) IV with pemetrexed 500 mg/m2 IV on day 1 every 21 days (Q3W) for 4 cycles
For squamous cell carcinoma: Carboplatin AUC 6 mg/mL/min IV/ paclitaxel IV 200 mg/m2 on day 1 every 21 days (Q3W) for 4 cycles (or 175 mg/m2 on D1 for Asian participant) Q3W for 4 cycles
For squamous cell carcinoma: Carboplatin AUC 6 mg/mL/min IV/ albumin-bound paclitaxel 100 mg/m2 on D1, 8 and 15 Q3W for 4 cycles
Patients will receive SRS/FSRT for all BM within ≤14 days from randomization, followed by 4 cycles of platinum-based chemotherapy combined with ivonescimab at 20 mg/kg every 3 weeks (Q3W).
The systemic therapy should be initiated within 7 to 10 days after the end of SRS/FSRT but no earlier than 3 days after its completion.
This will be followed by maintenance therapy with ivonescimab at 20 mg/kg plus pemetrexed (for patients with non-squamous NSCLC only) Q3W, for up to 2 years.
