Spots Global Cancer Trial Database for Elemene Plus Stupp Protocol Versus Stupp Protocol Alone for Newly-diagnosed Glioblastoma

Study Description

Brief Summary: The goal of this phase II randomized clinical trial is to compare the safety and efficacy of Elemene plus Stupp Protocol (the new protocol) and Stupp Protocol alone (the standard protocol) in patients with newly-diagnosed glioblastomas (ndGBMs). The main questions to answer are: * Whether the new treatment protocol (Elemene plus Stupp Protocol) is clinically safe for ndGBM patients. * Whether the new treatment protocol (Elemene plus Stupp Protocol) brings better survival benefits for ndGBM patients compared to the standard-of-care Stupp Protocol. Study participants will be enrolled in 5 hospitals in China and randomly assigned to receive either the new protocol or the standard protocol. The overall survival (OS) rate in the 12th month, the progression-free survival (PFS) rate in the 6th month, OS, PFS, and adverse events assessed by the CTCAE (Common Terminology Criteria for Adverse Events) will be evaluated for all patients.

Detailed Description: Glioblastoma (GBM) is a WHO grade 4 adult-type diffuse glioma and the most common malignant, primary brain tumor with a 5-year overall survival (OS) of only \~5% in real-world studies. The Stupp Protocol, consisting of fractionated focal irradiation in daily fractions of 2 Gy given 5 days/week for 6 weeks (a total of 60 Gy), plus concomitant daily temozolomide (TMZ, 75 mg/m2/day, 7 days/week from the first to the last day of radiotherapy) after maximal safe tumor resection, followed by six cycles of adjuvant TMZ (150-200 mg/m2/day for 5 days during each 28-day cycle), has been adopted as the standard of care for patients with newly-diagnosed GBMs (ndGBMs) since 2005. However, there have been no other treatment modalities except for tumor treating fields (TTFields) that have brought survival benefits for ndGBM patients during the past two decades. Since TTFields therapy is super expensive (about 1 million yuan/0.15 million dollars per year) and fewer than 10% of ndGBM patients can afford it around the globe, the Stupp Protocol is still being used as the first-line and the most widely-adopted treatment option for ndGBM patients around the world. Elemene, a Chinese anti-tumor medicine extracted from the plant Curcuma Wenyujin, has been isolated as a monomeric drug and has a broad-spectrum anti-tumor effect in various cancers, such as lung cancer, breast carcinoma, leukemia, and ovarian cancer. In recent years, its application in GBMs as revealed in the preliminary retrospective studies published in Chinese Journals and a few English Journals have shown survival benefits with acceptable toxicity. Elemene can pass through the blood-brain barrier because of its small molecular weight and lipid solubility and has synergistic anti-tumor effects with TMZ and radiotherapy for GBM patients. Several in vitro studies also have shown that Elemene could inhibit GBM cell proliferation, promote cell differentiation, and induce cancer cell apoptosis. All these findings from the above studies have indicated the potential survival benefits of Elemene in treating ndGBMs. However, so far, no clinical trials have tested the efficacy and safety of the new treatment protocol (Elemene added to the Stupp Protocol) for ndGBMs compared with the conventional Stupp protocol. In this study, the investigators aimed to launch a multi-center, phase II, randomized, controlled clinical trial to test the safety and efficacy of Elemene plus Stupp Protocol compared with Stupp Protocol alone for ndGBM patients.
