This randomized phase III trial examines whether lengthening the dosage interval in an adaptive manner for the prostate cancer drug lutetium 177 Lu PSMA RLT improves quality of life without decreasing lifespan when compared to the standard way this medication is given. This study is for patients with hormone resistant prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body. Hormone resistant prostate cancer often has many cells containing a protein called prostate-specific membrane antigen (PSMA) on their surface. The normal cells in the prostate do not normally express as much PSMA protein on their surface as cancer cells. Lutetium 177 Lu PSMA RLT binds to the PSMA protein on the tumor cells. It builds up in these cells and gives off radiation that may kill them. Typically, this medication is given at the same dose every 6 weeks for up to 6 doses. In this trial, researchers want to see if treatment following the first two doses of lutetium 177 Lu PSMA RLT can be delayed until there is evidence of disease activity. This may be an effective way to improve quality of life without decreasing lifespan in patients with advanced prostate cancer. Type: Interventional Start Date: Mar 2026 |

This phase III trial compares the effect of adding gemcitabine to intravesical Bacillus Calmette Guerin (BCG) versus intravesical BCG alone in patients with non-muscle invasive bladder cancer that has come back after a period of improvement (recurrent). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. Intravesical BCG is a solution containing the live BCG bacteria that is placed in the bladder via a catheter (intravesical). When the solution comes into direct contact with the bladder wall, it stimulates the body's immune system which kills tumor cells. Giving gemcitabine with intravesical BCG may kill more tumor cells in patients with recurrent non-muscle invasive bladder cancer. Type: Interventional Start Date: Jul 2025 |

This phase III trial compares the effect of adding docetaxel to hormonal therapy and apalutamide versus hormonal therapy and apalutamide alone in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Hormone therapy for prostate cancer, also called androgen deprivation therapy (ADT), uses surgery or drugs to lower the levels of male sex hormones in a man's body. This helps slow the growth of prostate cancer. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Giving docetaxel in addition to the usual treatment of hormonal therapy and apalutamide may work better in treating patients with metastatic prostate cancer than the usual treatment alone.

This project will evaluate the ability of Mirtazapine (MZP), a pharmacologically unique medication with a growing body of evidence to support its efficacy and safety for the treatment of methamphetamine (MA) use among medication for opioid use disorder (MOUD) patients, to significantly decrease MA use and related health-impairing behaviors. MZP has already successfully been used in the treatment of methamphetamine (detailed further below and in the Appendices). The investigators hypothesize that those assigned to the MZP plus treatment as usual (TAU) MZP+TAU arm will demonstrate significantly increased rates of biochemically verified abstinence from MA and other substances of abuse and experience improvements in health impairing behaviors relative to the placebo (PLO)+TAU arm across the 10-week treatment and follow-up periods.

This phase III trial compares total ablative therapy and usual systemic therapy to usual systemic therapy alone in treating patients with colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (IV) (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. Ablative means that the intention of the local treatment is to eliminate the cancer at that metastatic site. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. SABR, surgical resection, and microwave ablation have been tested for safety, but it is not scientifically proven that the addition of these treatments are beneficial for your stage of cancer. The addition of ablative local therapy to all known metastatic sites to the usual approach of systemic therapy could shrink or remove the tumor(s) or prevent the tumor(s) from returning.

- Leiomyosarcoma (LMS) is one of the more common soft tissue sarcomas (STS). - Patients presenting with large, high-grade, localized LMS are at significant risk of developing metastasis following curative surgery. - Clinical trials of neoadjuvant or adjuvant anthracycline and ifosfamide have suggested that patients with localized STS who are at high-risk of metastasis may benefit from chemotherapy, but the magnitude of benefit in unselected patient population is relatively small. - Currently, patient age, and tumor size and grade are used to assess risk of metastases and survival - Studies evaluating tumor response by imaging and histopathology have not established correlation between tumor characteristics as biomarkers for risk of metastasis or sarcoma recurrence. - Circulating tumor DNA (ctDNA) is present in blood of patients with advanced/metastatic LMS and may serve as biomarker of tumor response to chemotherapy. Blood samples will be collected prior to, during and after chemotherapy and analyzed for ctDNA and for mutations in genes that are associated with increased risk of developing sarcoma. Tumor tissue will be collected and analyzed for changes in genes. Digital images of the sarcoma from CT or MRI scans obtained during treatment will be obtained for advanced radiomic analysis. Patients will be followed for 2 years after study entry for signs of sarcoma recurrence. - A biomarker of tumor response and patient survival benefit from chemotherapy early in the course of chemotherapy would be of significant impact in treatment planning.
