Active clinical trials for "Recurrence"

The main objective of this project is to establish a shared comprehensive and systematic protocol for a multicenter prospective registry of patients undergoing salvage cryoablation of the prostate (SCAP). Our study hypothesis is that SCAP constitutes an effective and safe approach to treat local prostate cancer recurrence after brachytherapy or external beam radiation therapy (EBRT).

This is a phase 1b/2 open-label, multicenter, basket study to determine the safety, anti-tumor activity, tolerability, and pharmacokinetics /pharmacodynamics of AsiDNA in combination with olaparib in participants with recurrent epithelial ovarian cancer, breast cancer and metastatic castration-resistant prostate cancer who have progressed on previous Poly (ADP-ribose) polymerase (PARP) inhibitor therapy. The study will be conducted in two phases. The Phase 1b dose escalation study designed to establish the safety, tolerability, pharmacologically active doses/ maximum tolerated dose and/or recommended phase 2 dose of AsiDNA in combination with olaparib.

The goal of this clinical trial is to learn about treatment for a type of brain cancer called glioma. This clinical trial is for people with glioma who have been cancer-free for a period of time but their cancer has come back. The primary goals of this clinical trial are the following: To determine the recommended dose of PCI-24781 with metronomic temozolomide To evaluate side effects associated with using PCI-24781 with metronomic temozolomide

Patients with recurrent Glioblastoma (GBM) are commonly presented to surgeons, along with the question of whether or not to re-resect the recurrence. There is no Level 1 evidence to support a role for repeat surgery in this context, but a multitude of observational research suggests that repeat surgery may improve quality survival. Unfortunately, these studies all suffer from selection bias. The goal of this study is to provide a care trial context to help neurosurgeons manage patients presenting with recurrent GBM, with no additional risks, tests, or interventions than what they would normally encounter in routine care. Secondary goals include a test of the hypothesis that repeat resection can improve median overall survival, and that it can increase the number of days of survival outside of a hospital/nursing/palliative care facility.

The purpose of this study is to see how well pioglitazone, when used with cognitive behavioral therapy, works at helping people who have recently stopped using cocaine to continue to not use cocaine.

Significant advances in molecular nuclear medicine imaging in prostate cancer have been achieved in recent years. In particular, the introduction of prostate-specific membrane antigen (PSMA) -based tracers has significantly influenced diagnostic imaging of prostate. If cancer recurs after surgical removal of the prostate, targeted PSMA PET (positron emission tomography) can detect metastases even at very low PSA (prostate-specific Antigen) values. This increasingly allows individualized specific therapy of patients with prostate cancer recurrence. PSMA PET has now been included in national and international guidelines for the diagnosis of patients with biochemical recurrence of prostate cancer. Especially in patients in good general condition, with potentially longer life expectancy and early localized PSA recurrence, advances in molecular imaging are increasingly turning local therapy concepts into focus. Here both, radiotherapeutic (salvage radiotherapy of the lymphatic drainage) and surgical interventions (salvage lymph node dissection = removal of the pelvic lymph nodes) are offered on an individual basis. These regional therapies mainly aim to achieve a delay of further progression of the prostate cancer disease, and thus delay the initiation of palliative, sustained drug therapy. Previous standard or common practice at salvage lymph node dissection is the removal on both sides of the pelvic lymph nodes even if only one-sided suspicious lymph nodes are detected on imaging. Although the complications of salvage lymph node dissection are usually minor and manageable, they can still lead to impaired lymphatic drainage, leg edema, lymphocele formation or other surgical complications. The aim of the present study is to investigate whether a unilateral pelvic lymph node dissection on the side of conspicuous PSMA PET is sufficient and a dissection on the contralateral side can be dispensed without negatively impacting oncological outcomes and thereby sparing the patient the potential additional complications of a bilateral pelvic lymph node dissection.

Almost all gliomas relapse. After temozolomide rechallenge or combination with irinotecan, the progression-free survival rate at 6 months (PFS-6%) of recurrent glioblastoma was about 21%. After treatment with irinotecan-based chemotherapy regimen, the PFS-6% of recurrent lower-grade gliomas was 40%. The optimal chemotherapeutics of recurrent gliomas has yet to be determined. Anti-angiogenesis is a promising therapeutic strategy. Vascular endothelial growth factor-A (VEGF) is the primary driver of angiogenesis in tumors. Bevacizumab, a humanized monoclonal antibody directed against VEGF, is the prototypical anti-angiogenic drug and received accelerated approval of the United States Food and Drug Administration (FDA) for the treatment of recurrent glioblastoma. Bevacizumab inproved the PFS-6% (36%), but had no effect on the overall survival (OS) (9.2 months). Moreover, the effects of bevacizumab are transient and most patients' tumors progress just after a median time of 3-5 months. Recombinant human endostatin (rh-ES) is an endogenous broad-spectrum angiogenesis inhibitor that has been shown to significantly improve therapeutic efficacy when combining with conventional chemotherapy agents in non-small-cell lung cancer, breast cancer and melanoma. In our previous study, we retrospectively analyzed the effect and toxicity of rh-ES when combined with temozolomide and irinotecan on adult recurrent disseminated glioblastoma. After combined treatment, PFS-6% was 23.3%; the median PFS and OS were 3.2 and 6.9 months, respectively, which were promising compared with that in other studies. Once patients get radiographic remission in a short time (4 months), they may get a long PFS.The combined regimen did not reduce the sensitivity of tumor to bevacizumab. After tumor progression from the combined chemotherapy, bevacizumab usage could help to prolong the survival time (5.1 months versus 2.4 months). Moreover, the toxicities of the combination therapy in this study were manageable. On the basis of prior clinical experience, we carry out this prospective trial to confirm the efficacy and safety of the combination of rh-ES, temozolomide and irinotecan in patients with recurrent gliomas.

This prospective phase II study is to assess the efficacy and safety of thoracic re-irradiation for locoregionally recurrent non-small cell lung cancer using hypofractionated technique.

This phase II trial investigates the effect of NBTXR3, radiation therapy, and pembrolizumab in treating patients with head and neck squamous cancer that has come back (recurrent) or has spread to other places in the body (metastatic). NBTXR3 may help make tumor cells more sensitive to the radiation therapy. Radiation therapy, such as stereotactic body radiation therapy, uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. And hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving NBTXR3, radiation therapy, and pembrolizumab may kill more tumor cells.

This is a phase 2, non-randomized, interventional, open-label, multicenter trial evaluating the efficacy of VEN-AZA as a bridge-to-transplant therapy in chemotherapy-treated adult NPM1mut AML patients who experience molecular relapse or progression during treatment or follow-up. Subjects will receive cycles of venetoclax plus azacitidine. After each cycle, MRD will be evaluated and at any time of MRD-negativity, AlloSCT will be performed.
