NCT ID: NCT04383119 Recruiting - Soft Tissue Sarcoma Clinical Trials

Trial in Patients With Metastatic or Locally Advanced Leiomyosarcoma

ISG-ARTICLE
Start date: October 29, 2021
Phase: Phase 2
Study type: Interventional

Study is aimed at evaluating the activity of Trabectedin (arm A) in advanced leiomyosarcomas, having Gemcitabine (arm B) as the comparator. In addition to the randomized cohort, the study has also an observational prospective cohort which include patients who will refuse the randomization or for whom the investigator will not judge the randomization as an appropriate option. In order to allow the participation of sites only to the prospective-observational (non randomized) cohort, it was introduced the possibility to participate to the study and receive the ethical approval only to the Observational Prospective Cohort In parallel an optional translational study will be performed, in both cohorts, to identify factors predictive of the activity of Trabectedin or Gemcitabine in this specific histotype.

NCT ID: NCT04214457 Recruiting - Leiomyoma Clinical Trials

Development of a Predictive Model for Early Differential Diagnosis of Uterine Leiomyomas and Leiomyosarcomas

MYOSARC
Start date: September 20, 2019
Phase:
Study type: Observational

The development of an accurate and non-invasive diagnostic method is a priority in areas such as gynecology and oncology, specifically to improve the health of those patients with surgical indication for diagnosis of myometrial tumors: leiomyomas and/or leiomyosarcomas. Recently, Next Generation Sequencing (NGS) technology has been successfully applied in different areas of knowledge, being effective not only for the detection of DNA mutations, but also providing through bioinformatic tools, new insights in the understanding of chromosomal instability. In addition, the detection of circulating tumor DNA (ctDNA) through this type of techniques could revolutionize the non-invasive detection and monitoring of this type of tumors. The proposed study aims to perform the differential molecular analysis of myometrial tumor tissue (uterine leiomyomas / leiomyosarcomas), as well as peripheral blood of a group of patients with surgical indication of hysterectomy, laparoscopic or laparotomic myomectomy by diagnosis of myometrial tumors. Thus, the obtained samples will be processed for the realization of techniques of massive parallel sequencing or NGS that, together with a specialized bioinformatic software, will facilitate the interpretation of the obtained data. Combination of both platforms, sequencing and bioinformatics, will offer a high potential for the discovery of genetic variants and genomic markers. Depending on the results of these analyses, differential diagnosis of leiomyoma and leiomyosarcoma could be determined, in addition to increasing knowledge of myometrial biology and associated pathologies in a clinical and therapeutic context. Moreover, the application of this technology could allow the development of biomarkers and targeted therapies effective in the treatment of uterine leiomyomas and/or leiomyosarcomas.

NCT ID: NCT04055220 Recruiting - Osteosarcoma Clinical Trials

Efficacy and Safety of Regorafenib as Maintenance Therapy After First-line Treatment in Patients With Bone Sarcomas

REGOSTA
Start date: March 3, 2020
Phase: N/A
Study type: Interventional

This is a randomized, double-blinded, 2 arms study concerning patients with bone sarcoma after the first line therapy. In the first arm, patients will be treated with regorafenib for a maximum of 12 months as maintenance therapy after first line therapy, whereas in the second arm, patients will be treated with placebo (standard of care). The comparison between this two arms will allow to determine whether or not regorafenib is efficient for disease control, in terms of Relapse-Free Survival improvement.

NCT ID: NCT04031677 Recruiting - Leiomyosarcoma Clinical Trials

Phase: Phase 3
Study type: Interventional

This is a multicenter, randomized, open label phase lll trial to assess whether preoperative chemotherapy, as an adjunct to curative-intent surgery, improves the prognosis of high risk DDLPS (dedifferentiated Liposarcoma) and LMS (Leiomyosarcoma) patients as measured by disease free survival. After confirmation of eligibility criteria, patients will be randomized to either the standard arm or experimental arm.

Treatment of Metastatic Soft Tissue Sarcoma (STS) Patients (FIBROSARC USA)

FIBROSARC US
Start date: December 27, 2018
Phase: Phase 2
Study type: Interventional

The present study is an open-label, randomized, controlled, two-arm multi-center study of the efficacy of L19TNF treatment in combination with doxorubicin versus doxorubicin alone in metastatic leiomyosarcoma patients.

NCT ID: NCT02983539 Recruiting - Leiomyosarcoma Clinical Trials

Detection of Circulating Tumor Cells in Patients With Sarcomas

CTCS
Start date: October 2015
Phase:
Study type: Observational

The sarcomas represent 1% of all cancers in adults, 8% in adolescents and young people, and 10% in children. Even though it is a rare cancer, it contributes to a significant loss of years of life in comparison with other types of cancer, due the fact that it affects children and young people. The diagnosis and treatment are difficult, considering the diversity and rarity of this disease. In addition, on average, more than 50% of patients with high-grade sarcoma present tumor relapse and distant recurrence is considered the main cause of death. The presence of Circulating Tumor Cells (CTCs) in the blood of patients with sarcoma may be an early marker of tumor invasion, because it is known that the CTCs circulate in the blood for months or years before the development of metastases. The CTCs can be used to monitor the response of the tumor to treatment, in order to match time, dose, and type of therapy. Objectives: collect blood from patients with different types of sarcoma (leiomyosarcoma, synovial sarcoma, pleomorphic sarcoma and liposarcoma) in order to isolate and quantify CTCs. The investigators also have an intention to identify genes of resistance to treatment in these cells.

NCT ID: NCT02587169 Recruiting - Chondrosarcoma Clinical Trials

Trial of Nilotinib and Adriamycin as Treatment in Liposarcomas and Leiomyosarcomas of Retroperitoneum

GEIS-27
Start date: January 2012
Phase: Phase 1/Phase 2
Study type: Interventional

Phase I/II multicenter and prospective trial of nilotinib and adriamycin as neoadjuvant treatment in liposarcomas and leiomyosarcomas of retroperitoneum. The main objective of this study is to improve relapse-free survival (RFS)and overall survival (OS) decreasing from 50% to 30% the relapse percentage at 5 years in patients with resected sarcoma of retroperitoneum. Secondary objectives include the analysis of antitumoral activity through response rate (RECIST and tissular changes), the assessment of positive correlation between biomarkers and clinical results, the study of long term overall survival, and the analysis of the safety profile of the nilotinib-adriamycin combination. The trial hypothesis is that the nilotinib-adriamycin combination is synergistic and therefore better response results are expected (from 20% as P0 to 40% as P1). The study seeks to find a positive correlation between biomarkers and clinical results in retroperitoneal liposarcoma and leiomyosarcoma treated with the mentioned combination. The study involves the participation of 20 hospitals of the Spanish Sarcoma Group (GEIS). The treatment consists of 4 neoadjuvant cycles of nilotinib-adriamycin on patients with resectable retroperitoneal sarcoma. The research comprises a robust translational study as well as histological and radiological reviews.
