Intravesical BCG vs GEMDOCE in NMIBC
NCT05538663
Recruiting
The study hypothesis is that BCG naïve non-muscle invasive bladder cancer (NMIBC) patients treated with intravesical Gemcitabine + Docetaxel (GEMDOCE) will result in a non-inferior event-free survival (EFS) compared to standard treatment with intravesical BCG. The purpose of this study is to test whether Gemcitabine + Docetaxel is a better or worse treatment than the usual BCG therapy approach. The primary objective of this study is to determine the event free survival (EFS) of BCG-naïve high gr... Read More

Testing the Combination of Two Anticancer Drugs M1774 (Tuvusertib) and Avelumab to Evaluate Their Safety and Effectiveness in Treating Merkel Cell Skin Cancer, MATRiX Trial
NCT05947500
Recruiting
This phase II trial compares tuvusertib in combination with avelumab to tuvusertib alone to determine whether the combination therapy will lengthen the time before the cancer starts getting worse in patients with Merkel cell cancer that has not responded to previous treatment (refractory). Tuvusertib is a drug that inhibits an enzyme called ataxia telangiectasia and Rad3 related (ATR) kinase, which is an enzyme that plays a role in repair of damaged deoxyribonucleic acid (DNA) as well as tumor c...

A Study Comparing Anitocabtagene Autoleucel to Standard of Care Therapy in Participants With Relapsed/ Refractory Multiple Myeloma
NCT06413498
Recruiting
The goal of this study (iMMagine-3) is to compare the study drug, anitocabtagene autoleucel to standard of care therapy (SOCT) in participants with relapsed/refractory multiple myeloma who have received 1 to 3 prior lines of therapy, including an anti-CD38 monoclonal antibody and an immunomodulatory drug. The primary objective of this study is to compare the efficacy of anitocabtagene autoleucel versus SOCT in participants with RRMM.

A Multicenter Study of Continued Current Therapy vs Transition to Ofatumumab After Neurofilament (NfL) Elevation
NCT05090371
Recruiting
This study will evaluate if relapsing-remitting MS patients that have not had a relapse in the past year would benefit from a switch to ofatumumab versus staying on their continued current therapy. This study will also look at whether an elevated serum neurofilament light (NfL) level predicts enhanced benefit from a switch to ofatumumab.

A Study of Pembrolizumab (MK-3475) With or Without Intismeran Autogene (V940) in Participants With Non-small Cell Lung Cancer (V940-009/INTerpath-009)
NCT06623422
Recruiting
The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).
