Type of Application: Clinical trial of new indication. Experimental drug: The study dose of temsirolimus will be 25 mg administered intravenously, infused over a 30- to 60-minute period once weekly for 28 days (Total doses: 4 doses). Temsirolimus is a selective inhibitor of mTOR (mammalian target of rapamycin). Pharmacotherapeutic group: Protein Kinase Inhibitors; ATC code: L01X E09. Primary Objective: To identify in tumor samples future biomarkers associated with a short term exposure to temsirolimus. This is an exploratory clinical study. No efficacy objectives are included in this clinical trial. Secondary Objectives: To estimate the tolerability for all temsirolimus-treated patients throughout the study and up to 28 days after the last dose of temsirolimus. To correlate observed changes with the different type of endometrial carcinoma (type I and type II), with regard to proteins related to mTOR (p4EBP1, pS6K1, c-MYC, cyclin D, p27, BAD, p53, Bcl-2 PTEN, pAKT, mTOR), To estimate the potential predictive value of some biomarkers (immunostaining for PTEN, pAKT, mTOR), relevant mutations in PTEN, PI3KCA, k-RAS, CTNNB1, and microsatellite instability status. To estimate the prognostic value of Ki67 expression after short-term presurgical therapy exposure To collect data about the differences in expression profile, assessed by RNA microarrays

This is a prospective, open-label, randomized controlled clinical intervention study to evaluate the efficacy and safety of all-trans retinoic acid (ATRA) in treating patients with recurrent metastatic adenoid cystic carcinoma of the head and neck.

A one-arm exploratory clinical research program Study of Apatinib in Advanced Metastatic Renal Cell Carcinoma （mRCC） Patients.It's arm to evaluate the treatment of advanced metastatic renal cell carcinoma in patients with objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), quality of life score (QoL) and safety.

Hepatocellular carcinoma (HCC) is one of the lethal human cancers worldwide and its incidence matches mortality, reflecting the poor prognosis of this disease. The surgical resection rate of HCC is low, and the prognosis is poor. Although transarterial chemoembolization (TACE) is the main treatment for HCC patients who are not candidates for surgical resection, it is not considered a curative procedure. For HCC, poor TACE efficacy or TACE failure may be related to tumor angiogenesis of the residual disease. Among the many regulatory factors in tumor angiogenesis, hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) play vital roles in this process. Sorafenib is the first systemic treatment drug, which has been approved by the FDA for advanced HCC. In order to find an new VEGFR-inhibitor with better effect and lower toxicity, Jiangsu Hengrui Medicine Co., Ltd. developed Apatinib, a high-performance VEGFR-2 tyrosine kinase inhibitor. Apatinib plays anti angiogenic effect in the treatment of malignant tumor mainly through inhibition of VEGFR-2, in vivo and in vitro experiments showed good tumor growth inhibitory activity on glioma, this study aims to further verify the efficacy and safety of Apatinib for first-line treatment failure hepatocellular carcinoma patients, the primary endpoint is time to progression(TTP).

Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world. For patients with intermediate HCC (BCLC stage B), transarterial chemoembolization (TACE) has been recommended as the standard therapy in many clinical practice guidelines. The combination of TACE and radiofrequency ablation (RFA) has also been reported as an effective treatment. However, more and more retrospective studies have reported better therapeutic efficacy of hepatic resection than TACE for intermediate HCC. The purpose of this study was to compare the efficacy of hepatic resection versus TACE+RFA for the treatment of intermediate HCC through prospective randomized clinical trial.

Currently, concurrent chemoradiotherapy with/without sequential chemotherapy is the standard treatment modality for intermediate risk NPC (stage II and T3N0M0) according to the National Comprehensive Cancer Network guideline. However these recommendations were based on the evidence in the two-dimensional conventional radiotherapy (2DCRT) era. The introduction of intensity-modulated radiotherapy (IMRT) in NPC treatment has brought substantial better treatment outcomes than 2DCRT. It has been questioned whether additional concurrent chemotherapy is still necessary for intermediate risk NPC within the excellent framework of IMRT. Thus, the investigators jointly conduct the first non-inferior randomized trial to determine the value of concurrent chemotherapy with cisplatin for intermediate risk NPC patients treated with IMRT. Given the results of clinical studies mentioned above,the investigators decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43

Cisplatin Combined With S-1 or Paclitaxel as First-line Treatment for Metastatic Esophageal Squamous Cell Carcinoma

ABACUS is an open-label, international, multi-centre, window of opportunity phase II trial for patients with histologically confirmed (T2-T4a) transitional cell carcinoma of the bladder. The trial aims to test the efficacy of preoperative MPDL3280A and will include extensive biomarker work on samples from these patients. Eligible patients will receive two 3-weekly cycles of MPDL3280A pre-cystectomy. Following cystectomy, patients will be followed up for safety, survival, and disease data.

Verify the effect and the incidence of oral mucositis of concurrent chemoradiotherapy in locally advanced squamous cell carcinoma of the head and neck versus concomitant cetuximab with radiotherapy after neoadjuvant chemotherapy. The predictive effect of Apurinic/apyrimidinic endonuclease 1(APE1)/ Ref-1 protein and Apurinic/apyrimidinic endonuclease 1(APE1)/Ref-1 antibody on oral mucositis.

Several prospective randomized trials have demonstrated that concurrent chemoradiotherapy was superior to radiotherapy alone in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). Based on these evidences, concurrent chemoradiotherapy (CCRT) with/without sequential chemotherapy has become the standard care for locoregionally advanced NPC. However, most of these evidences of standard treatment for locoregionally advanced NPC were based on the two-dimensional conventional radiotherapy (2DCRT). As the intensity-modulated radiation therapy (IMRT) technique has been widely used in the last decades, IMRT improved the treatment outcomes of patients with NPC, especially the local control rate. Currently, more retrospective studies compared the IMRT alone vs. IMRT plus concurrent chemotherapy, and reported that concurrent chemotherapy failed to improve survival rates for patients with locoregionally advanced disease, but increased the severity of acute toxicities. People started to reconsider the role of CCRT. Therefore, we propose this randomized phase III non-inferiority study to reassess the efficacy and contribution of concurrent chemotherapy in locoregionally advanced NPC during IMRT era.
