| Popis: | e14014 Background: Nearly all patients (pts) with glioblastoma (GBM) will suffered relapse or disease progression after resection and adjuvant radiotherapy and temozolomide (TMZ). Anlotinib is a new multikinase inhibitors (MKI) blocking angiogenesis and tumor cell proliferation simultaneously and a prospective phase II study was performed to explore the potency of the combination anlotinib and TMZ for pts with relapse or progression GBM. Here, we reports the preliminary results of this study. Methods: This is a prospective, single-arm, open label, phase II study (NCT04547855). Eligible pts were diagnosed with histologically confirmed glioblastoma and experienced relapse or progression for the first time from surgery (including biopsy, partial resection and total resection) and radiotherapy-TMZ therapy (STUPP regimen). Other criteria included 18 to 75 years age, Karnofsky performance status (KPS) ≥ 60% and adequate organ function. The primary endpoint was progression free survival at 6 months (6m-PFS). All pts received orally TMZ (150 mg/m2) from D1-D7 every 2 weeks and anlotinib (12mg, QD) from D1-D14 every 3 weeks until disease progression or unacceptable toxicities. Results: From July 2020 to November 2021, 25 pts were enrolled. The median age was 49 (rang: 23, 62) and the median KPS was 80 (range: 60, 100). Most pts had poor prognostic factors that 17 pts (70.8%) had unmethylated MGMT promoter and 22 pts (91.6%) were IDH wild-type, which 24 pts detected IDH and MGMT status. At the data cutoff date on January 2022, the 6m-PFS was 25.2% and the median PFS was 4.2 months (95% CI, 3.4-5.0m). The median OS reached 9.1 months (95% CI, 8.1-10.2). Tumor response was assessed for all pts. 7 pts achieved partial response and the objective response rate was 28%. 10 pts had stable disease and the disease control rate was 68%. The most common grade 3 or worse adverse events (AEs) was lympyhopenia (48.0%), which may be caused by TMZ. No death was attributed to AEs. Conclusions: Combination of anlotinib and dose-intense temozolomide was tolerable in the treatment of recurrent or progressive glioblastoma. Preliminary results indicated that the efficacy was promising for those miserable pts with worse prognosis factors. Further investigation was ongoing. Clinical trial information: NCT04547855. |
