A Phase III Study of AZD0780 on Major Adverse CV Events in Patients With a History of ASCVD Events or at High Risk for a First Event
Recruiting
The purpose of this phase 3, randomized, placebo controlled, event-driven study is to assess the effect of AZD0780, an oral PCSK9 inhibitor, compared with placebo in reducing the risk of MACE-PLUS in patients with established ASCVD or at high risk for a first ASCVD event. The effect of AZD0780 vs placebo on the risk of MACE-PLUS will be evaluated from randomisation until the primary analysis censoring date (PACD). The Study Closure Visit will be scheduled to occur after the PACD and will be the... Read More

Ultra-hypofractionated Whole Breast Irradiation With Lumpectomy Cavity Boost for the Treatment of Stage I-III Breast Cancer
Recruiting
This clinical trial tests how well ultra-hypofractionated (UF) whole breast irradiation (WBI) with lumpectomy cavity boost (CB) works in treating patients with stage I-III breast cancer. Breast conservation therapy (BCT) is the recommended treatment for patients with early stage breast cancer. BCT involves a lumpectomy followed by breast radiation. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Traditionally, WBI has been given o... Read More

A Phase 2 Trial in Healthy Adult Participants of the Recombinant MVA-BN-WEV Vaccine
Recruiting
This phase 2 clinical trial will investigate an optimal dose, dosing regimen, and evaluate reactogenicity, safety and immunogenicity in healthy adult participants of the recombinant, multivalent MVA-BN-WEV vaccine. MVA-BN-WEV is intended for active immunization for prevention of disease induced by VEEV and EEEV, in persons aged 18 years and older at high risk of exposure.

Zanubrutinib in Combination With Sonrotoclax for the Treatment of Underrepresented Ethnic and Racial Minorities With Relapsed or Refractory B-cell Non-Hodgkin Lymphoma
Recruiting
This phase I trial tests zanubrutinib in combination with sonrotoclax for treating underrepresented ethnic and racial minorities with B-cell non-Hodgkin lymphoma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Many racial and ethnic minorities face additional treatment challenges which may lead to poorer outcomes, however, there are fewer racial and ethnic minorities participating in clinical trials. Zanubrutinib, a type o... Read More

Targeting Collagen VII Antibodies With IV IgG in Dystrophic Epidermolysis Bullosa
Recruiting
The study objective is to see if IV IgG treatment in Recessive Dystrophic Epidermolysis Bullosa (RDEB) skin in conjunction with VYJUVEK treatment improves wound healing and affects the levels of C7 and HSV-1 antibody levels in serum. Fewer wounds, more rapidly healing wounds, and decreased C7 and HSV-1 antibodies could improve quality of life.
