A Single-Center Study to Characterize the Safety and Efficacy of Ublituximab in Older Adults With Relapsing Forms of Multiple Sclerosis (RMS)

This study is being done to see how safe and effective ublituximab is when given to older adult patients for their RMS. Since RMS patients over age 55 were excluded from previous clinical studies that studied the safety and efficacy of ublituximab, this study is designed to better understand how well this drug is tolerated in RMS patients between the ages of 55-80 years. Primary endpoints include: - Incidence of infection rate from Baseline to Month 24/EOS (including UTI and other active acute, opportunistic and/or chronic infection) - Incidence of TEAS/SAEs from Baseline to Month 24 with consideration to nature, severity, and occurrence rate of AEs Approximately 20 participants are expected to be enrolled. Participation in this study will last approximately 24 months and will include approximately 6 study visits to the study center.

A Study of Telitacicept for the Treatment of Generalized Myasthenia Gravis (RemeMG)

Myasthenia gravis (MG) is an autoimmune disease that affects the neuromuscular junction on the postsynaptic membrane. The predominant manifestation is muscle weakness, which typically worsens with repeated muscle exertion, such that function is usually the best in the morning with more pronounced weakness at the end of the day. A major challenge in MG is the lack of therapies that cure the disease. Telitacicept is a fully human TACI-Fc fusion protein that targets B-lymphocyte stimulator (BLyS) and A proliferating-inducing ligand (APRIL), neutralizing their interactions with receptors on B cells. The blockage of BLyS and APRIL interaction with their respective cell membrane receptors (transmembrane activator and CAML interactor [TACI], B-cell maturation antigen, and BLyS receptors) by telitacicept would inhibit B-cell proliferation and maturation. This suppression at the proximal portion of the immune response could alleviate autoimmune symptoms. This study is a randomized, double-blind, placebo-controlled Phase 3 study with an open-label extension to evaluate the efficacy and safety of telitacicept in a global patient population with gMG.

The CDK4/6 Inhibitor Dosing Knowledge (CDK) Study

The CDK4/6 Inhibitor Dosing Knowledge Study (CDK Study) will study CDK4/6 inhibitor dosing regimens in patients 65 or older with Metastatic Breast Cancer (MBC). The overarching goal of this pragmatic, randomized trial is to compare an "indicated" dosing approach, as listed on the FDA-approved drug label, that starts at the full dose of a CDK4/6 inhibitor (palbociclib or ribociclib) with dose reduction based on tolerability versus a "titrated" dosing approach that starts at a lower dose of a CDK4/6 inhibitor and then titrates up to full dose as tolerated. CDK4/6 inhibitors will be given in combination with endocrine therapy (either an aromatase inhibitor (AI) or fulvestrant) based on the choice of the treating clinician. The primary endpoint will be time to treatment discontinuation (TTD), defined as the time from randomization to last dose of the CDK4/6 inhibitor. The hypothesis is that starting low and escalating as tolerated will help older patients (> 65 years) stay on therapy longer. Eligibility criteria are broad to allow patients who are not typically included in clinical trials to participate, allowing for a more representative sample of participants. The investigators will conduct sub-group analyses based on age (65-74 years vs. ≥75 years) and baseline frailty scores. This study builds upon the lessons learned from prior studies with CDK4/6 inhibitors. The investigators will augment the standard assessment of treatment toxicities assessed by the health care team with prospectively collected patient-reported outcomes data to better reflect how participants tolerate the different dosing approaches.

ALPINE: Maintenance Letrozole/Abemaciclib Vs Pembrolizumab

This is a randomized, phase 2 trial of maintenance letrozole + abemaciclib vs. pembrolizumab after carboplatin + paclitaxel + pembrolizumab chemotherapy in participants with advanced or recurrent estrogen receptor (ER) positive (ER+), mismatch repair proficient (MMRP), TP53 wild-type endometrial cancer. Participants will be randomized in one of two study groups: Abemaciclib + Letrozole vs. Pembrolizumab. Randomization means that a participant is placed into a study group by chance. The U.S. Food and Drug Administration (FDA) has not approved abemaciclib, letrozole or pembrolizumab for endometrial cancer but they have been approved for other uses. The research study procedures include screening for eligibility, study treatment visits, X-rays, Computerized Tomography (CT) scans, Magnetic Resonance Imaging (MRI) scans, Positron Emission Tomography (PET) scans, blood tests, and electrocardiograms (EKGs). Participants will be administered study drugs for up to 2 years and will be followed for 3 years after completing study treatment. It is expected that about 76 people will take part in this research study. Eli Lilly is supporting this research study by providing funding and the study drug abemaciclib.

Efficacy and Safety Studies of Frexalimab (SAR441344) in Adults With Relapsing Forms of Multiple Sclerosis

STOP-HER2: Stopping Trastuzumab in HER2+ MBC

This is a single arm, phase II study of cessation of anti-HER2 systemic therapy in exceptional responders with HER2-positive metastatic breast cancer (MBC), defined as individuals free of disease progression after at least 3 years of first-line treatment. This research study will include two different groups (cohorts) of patients. Those not wanting to stop anti-HER2 maintenance treatment will be included in a non-randomized, observational cohort (cohort 1). Those willing to stop maintenance anti-HER2 treatment you will be included in cohort 2. This study is trying to understand whether blood samples that may contain traces of DNA from cancer, known as "circulating tumor DNA" or "ctDNA" are able to help identify which patients can successfully stop treatment without a change in their cancer. The research study procedures include: an initial screening phase followed by periodic visits with blood work, questionnaires, and body scans. It is expected that about 82 people will take part in this research study (52 in cohort 2 (stopping treatment), 30 in cohort 1 (continuing treatment). This study is expected to last 1 year with 10 years of follow up. The Susan G. Komen Foundation, the Gateway for Cancer Research - both nonprofit foundations supporting cancer research - and the National Institutes of Health are supporting this research study by providing funds. This study is also being supported by Johns Hopkins University on behalf of the Translational Breast Cancer Research Consortium (TBCRC). The TBCRC is a group of academic medical centers across the United States that work together to conduct breast cancer research.

RecoverPC: Relugolix vs GnRH Agonist in Quality of Life

This is a phase 2 clinical trial comparing patient-reported Quality of Life (QOL) among men with localized or biochemically recurrent prostate cancer treated with relugolix versus leuprolide depot therapy. Participants will be randomized into one of the study groups leuprolide versus relugolix. Randomization means that a participant is put into a study group by chance. The U.S. Food and Drug Administration (FDA) has approved leuprolide and relugolix as treatment options for prostate cancer. The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits, ECGs, and blood tests. Participation in this research study is expected to last 12 months. It is expected about 110 people will take part in this research study. The Prostate Cancer Foundation and Pfizer are supporting this research study by providing funding. Myovant is supporting this study by providing the drug, Relugolix.
