Brief Summary

This is a open-label, multi-center prospective observation study for the efficacy and safety of intraventricle pemetrexed disodium via ommaya reservoir in the treatment of leptomeningeal metastasis with lung cancer who have failed at least one targeted therapy. In detail: At least the treatment failure was after third-generation EGFR-TKIs in EGFR-mutated lung cancer; or at least the treatment failure was after second-generation ALK-TKIs in ALK-mutated lung cancer; or at least the treatment failure was after one-line of targeted-TKIs in ROS1-mutated non-squamous non-small lung cancer.

Detailed Description

Participants were randomizedly assigned in cohort 1 who will be given pemetrexed 20mg every 24 hours for 72 hours every 2 weeks,or in cohort 2 will be given pemetrexed 30mg once a week.

It was designed for two stages on treatment course. Induction therapy: Efficacy evaluation every 2 cycles, and confirm the efficacy at the next cycle. If at the next cycle, the efficacy result changed (such as SD or PR after initial PD; or PD after initial SD or PR; the second time of efficacy assess was required）. If the CSF cytology at the time of the efficacy evaluation was negative, one more cycle was required to confirm the CSF cytology.

Consolidation: If the efficacy is remission(including complete remission, obvious remission, or partial remission) or stable disease for initial timepoint and the timepoint of the confirmed evaluation; then the patient will be advanced to the stage of consolidation treatment. Participants in cohort 1 who will be given pemetrexed 20mg every 24 hours for 72 hours every 3 weeks. Participants in cohort 2 will be given pemetrexed 30mg every 3 weeks. Until the toxicity is intolerable, or disease progression.

Cross over： Compared the first 4 enrolled cases in each group; the comprehensive evaluation(including efficacy, cytology negative, toxicity) in better group(50% higher efficacy or 50% less toxicity) will be the following cohort, to which the other one will crossover.

Eligibility Criteria

Inclusion Criteria

1. confirmed pathologic diagnosis (histologic type of non-squamous non-small cell lung cancer in the primary lesion or metastatic lesion) with definitely genetic testing results (EGFR/ALK/ROS1);

2. In accordance with the CSCO Guidelines for the Diagnosis and Management of Central Nervous System Tumors, and the EANO-ESMO diagnostic criteria: a diagnosis of type I meningeal metastatic carcinoma is made when cerebrospinal fluid cytology testing reveals anisocytosis (3 consecutive tests are required if the cerebrospinal fluid cytology testing is initially negative for the patient) (one study showed that the specificity of anisocytosis in diagnosing meningeal metastases in patients with solid tumors was 100%) or meningeal lesions Biopsy confirms the diagnosis. (Type IIA-C meningeal metastases: negative or atypical cerebrospinal fluid cytology, MRI showing linear or/and nodular meningeal enhancement^ with typical clinical symptoms*).

• MRI: at least 1.5T; demonstrates sulcal, smear, or linear ventricular enhancement, cranial nerve root enhancement or nodular meningeal enhancement, or cauda equina spinal enhancement; control enhancement T1-weighted sequences and Flair sequences; nodularity is defined as foci of ≥ 5x10mm enhancement; sequences of choice: cranial planar enhancement + T2Flair (enhancement) or and total spinal planar enhancement (when suspicion of spinal involvement); 3D T1 enhancement (involved cranial nerves - optional); cerebrospinal fluid flow imaging (functional or anatomic).

• Typical clinical manifestations: headache, nausea, vomiting; epilepsy; mental changes, gait difficulties; cranial nerve damage (diplopia, visual abnormalities, hearing abnormalities, facial nerve palsy, difficulty chewing, difficulty swallowing, choking, etc.); neurogenic signs (cauda equina symptoms, mainly perineal numbness, tingling, defecation and urination disturbances, weakness or incomplete paralysis of both lower limbs); sensorimotor defects of the limbs; cervical back Radicular pain; be careful to differentiate from signs and symptoms of brain parenchymal metastases, extracranial disease, treatment-related adverse effects, and non-tumor comorbidities.

3. Based on the guideline-driven first-line choice of TKI agents for gene-positive patients, enrolment would therefore require: failure of at least three generations of EGFR-TKIs for patients with EGFR mutations; failure of at least second-generation ALK inhibitors for ALK mutations; and failure of at least one ROS1 inhibitor for ROS1 mutations.

4. No contraindication to Ommaya capsule implantation. 5. Female subjects who are capable of becoming pregnant must agree to use reliable contraception throughout the trial; male subjects whose female partner is capable of becoming pregnant must agree to use reliable contraception throughout the trial.

6. patients must sign an informed consent form and must be willing and able to comply with visits, treatment regimens, laboratory tests and other requirements as specified in the study protocol

Exclusion Criteria

1. HBsAg-positive patients may be enrolled, but patients with higher than normal viral copy number or HBcAb-positive patients should receive effective anti-HBV treatment until 6 months after the end of the trial. HCV RNA carriers may be enrolled, but need to receive effective anti-HCV treatment throughout the trial, and continue to receive effective anti-HCV treatment until 6 months after the end of the trial.

2. human immunodeficiency virus (HIV) infection.

3. significant extracranial lesion progression or extensive extracranial lesions causing severe symptoms that cannot be effectively treated.

4. patients with extreme emaciation or cachexia.

5. Extensive parenchymal brain lesions with severe symptoms that cannot be effectively treated.

6. patients with other malignant tumors that are currently undergoing treatment.

7. have received or will receive a live vaccine within 30 days prior to signing the informed consent form.

8. other conditions that, in the judgment of the investigator, may affect subject safety or trial compliance, including symptomatic heart failure, unstable angina, myocardial infarction, active infections (including tuberculosis infections) requiring systemic therapy; or severe organ dysfunction, with creatinine clearance <45 ml/min calculated from glomerular filtration rate by the Cockcroft-Gault formula or by the Tc99m-DPTA serum clearance method; an absolute neutrophil count <0.5 x 109/L; a platelet count <25 x 109/L, or in patients with severe active visceral bleeding; or severe Abnormal liver function (bilirubin greater than 3.0 times upper limit of normal; AST and ALT greater than 5.0 times upper limit of normal).

9. patients with known hypersensitivity to pemetrexed with a history of serious adverse reactions, and patients with potentially life-threatening conditions for reuse.

10. pregnant or lactating women.
