Interventions

  • Ommaya reservoir — DEVICE
    Intrathecal chemotherapy through Ommaya reservoir
  • Systematic chemotherapy — DRUG
    Systematic chemotherapy: including capecitabine(1000mg/m2 bid, d1-14, q3w, po), gemcitabine(1000mg/m2, d1,8, q3w, ivgtt), vinorelbine(60mg/m2, qw, po), docetaxel(75mg/m2, d1, q3w, ivgtt),Nab-paclitaxel(125mg/m2, d1,8, q3w, ivgtt), iribrin(1.4mg/m2, d1,8, q3w, ivgtt), DS8201(5.4mg/kg, d1, q3w, ivgtt), sacituzumab govitecan(10mg/kg, d1,8, q3w, ivgtt) or SKB264(5mg/kg, d1, q2w, ivgtt).
  • Intrathecal chemotherapy — DRUG
    Intrathecal chemotherapy through Ommaya reservoir: including MTX(10-12mg, q1-3w), thiotepa(10mg, q1-3w), cytarabine(30mg/m2, q1-3w), cytarabine liposome(50mg, q1-3w), pemetrexed(50mg, q1-3w), or DS8201(The frequency and cycle of drug administration are determined based on the results of the Phase I/II clinical trial of intrathecal injection of DS8201 in our center).

Study Details

This is a prospective, multicenter, randomized controlled, open-label investigator-initiated clinical study to evaluate the clinical efficacy and quality of life of intrathecal chemotherapy through Ommaya reservoir in combination with systematic chemotherapy versus systemic chemotherapy alone in patients with Her-2 negative breast cancer with leptomeningeal metastasis.
