NCT03987503
Direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) offers a cure to those with chronic HCV infection. For marginalized communities, linkage to care services often aren't enough to overcome barriers to accessing the medical system. For difficult to link populations, offering treatment at the same non-clinical community space may improve uptake and reduce loss-to-follow-up. The purpose of this 2 year study is to assess the feasibility, acceptability and effectiveness of accelerated initiation of commercially available DAA therapy targeting socially marginalized communities (e.g., medically underserved, homeless, people actively injecting drugs). The study will be carried out at two community sites that perform HCV testing: (a) fixed community site and (b) community mobile site via clinical research van. Participants (n=150) who test anti-HCV positive and HCV RNA positive (chronic infection) are invited to enroll into the no one waits (NOW) Study and begin HCV treatment at point of diagnosis. All evaluation, medication dissemination, and follow-up care will take place at the project site. The investigators will estimate the effect of on-site point-of-diagnosis (POD) treatment on (1) time from HCV testing to treatment initiation, (2) completing treatment, and (3) attaining (sustained virologic response) SVR-12; overall and by study site. A secondary product will be a lesson learned guide of recommendations for implementing a POD on-site test and treat program for dissemination beyond San Francisco.
NCT06055868
This is an exploratory qualitative study among People Living With HIV (PLWH) of diverse racial/ethnic and sexual and gender minority (SGM) identities to explore individual, interpersonal, and structural oral health equity factors that serve as barriers or facilitators of accessing oral health care, knowledge and perceptions of human papillomavirus (HPV) vaccination and Oral squamous cell carcinoma (OSCC) /Oropharyngeal squamous cell carcinoma (OPSCC), and to collect recommendations on how to increase access to oral health care and engage PLWH in OSCC/OPSCC prevention.
NCT06014905
This is a Pilot/Phase I clinical study of hyperpolarized 13C (HP 13C) pyruvate injection that includes the acquisition of magnetic resonance (MR) data performed on participants with meningioma to evaluate metabolism and aid in the non-invasive characterization of aggressive tumor behavior
NCT02713386
This phase I/II trial studies the side effects and the best dose of ruxolitinib phosphate when given together with paclitaxel and carboplatin and to see how well they work in treating patients with stage III-IV epithelial ovarian, fallopian tube, or primary peritoneal cancer. Ruxolitinib phosphate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ruxolitinib phosphate together with paclitaxel and carboplatin may be a better treatment for epithelial ovarian, fallopian tube, or primary peritoneal cancer compared to paclitaxel and carboplatin alone.
NCT04732221
This is a two-part (Phase 2/Phase 3) study of frespaciguat, an inhaled soluble guanylate cyclase stimulator, in participants with pulmonary arterial hypertension (PAH). The first part (Phase 2) will assess three different doses of frespaciguat compared to placebo in a base period of 12 weeks, followed by comparison of three different doses of frespaciguat during an optional 40 month extension period. The treatment dose with the best efficacy and safety profile in the phase 2 cohort base period will be selected for use in the second part (Phase 3) of the study. The primary hypothesis of Phase 2 is that at least one frespaciguat dose is superior to placebo in reducing pulmonary vascular resistance (PVR) from baseline at week 12. The purpose of the second part (Phase 3) of the study is to confirm the efficacy, safety, and tolerability of frespaciguat at the selected dose compared to placebo during a 12 week base period followed by an extension period of up to 5 years. The primary hypothesis of Phase 3 is that frespaciguat is superior to placebo in increasing 6-minute walk distance (6MWD) from baseline at week 12. Due to sponsor's decision this phase/part was not conducted.

NCT06185959
This study's overarching aim is to evaluate a new psychoeducation and process group for Asian and Asian American psychiatric outpatients. This is a 12 week mental health group which will focus on both educational content related to Asian mental health as well as increasing connection between group members. We hypothesize that participants in the group will experience a decrease in psychiatric symptoms at the conclusion of the group compared to their symptoms at the beginning of group. We also hypothesize that participants will feel more socially connected after the group.

NCT04398745
Belantamab mafodotin is an antibody-drug conjugate (ADC) containing humanized anti- B-cell maturation antigen (BCMA) monoclonal antibody (mAb). Renal impairment is a major complication of multiple myeloma (MM) and the majority of MM participants is either at risk or already has renal dysfunction at initial diagnosis. The purpose of this study is to assess the pharmacokinetics (PK), safety, and tolerability of belantamab mafodotin monotherapy in participants with RRMM, who have had at least 3 lines of prior treatment (or at least 2 lines of prior treatment if ineligible for autologous stem cell transplantation ) and have either normal or impaired renal functions. The study will consist of two parts: part 1 will include participants with normal/mildly impaired renal function and severe renal impairment and part 2 will include participants with end-stage renal disease (ESRD), where participants are either not undergoing or require hemodialysis. Participants will be administered belantamab mafodotin at a dose of 2.5 milligram per kilogram (mg/kg) intravenously once in three weeks (Q3W) dosing in Part 1. Based on the Part 1 Safety/Pharmacokinetic (PK) data, Part 2 participants will be administered the dose of either 2.5 mg/kg or 1.9 mg/kg (or other adjusted dose). Participants will be treated with belantamab mafodotin monotherapy until confirmed disease progression, death, unacceptable toxicity, withdrawal of consent, or end of study, whichever occurs first. This study will include a screening phase, treatment phase, follow-up phase and a post analysis continued treatment (PACT) phase . The total duration of the study is approximately up to 48 months.

Clinic visits will occur 4 weeks after the baseline visit, and then every 12 weeks until the end of the study. The safety of simufilam, and its efficacy in enhancing cognition and slowing cognitive and functional decline will be evaluated.
NCT04737421
This is a multicenter, prospective, non-interventional study in which a total of 1000 subjects in need of a single, multiple or full arch restoration in any region of the mouth (healed or extracted) will be treated in up to 30 study centers. The primary aim of this study is to demonstrate non-inferiority of all NobelBiocare TiUltra implants to historic data from NobelActive TiUnite coated implant in terms of marginal bone level change over 5 years after final prosthetic delivery. Eligible subjects who provide their informed consent for participation will be enrolled into one of four groups, each sized to 250 individuals. They will be treated with the corresponding implant system assigned to the group. The allocation into a certain group is only driven by the subject's clinical and restorative requirement and standard of care at the enrolling study clinic. Each subject will be followed for 5 years after definitive prosthetic placement

NCT05748483
A migraine is a moderate to severe headache on one side of the head that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. The main goal of the study is to evaluate the tolerability (how patients handle the study treatment) and safety of atogepant compared to topiramate in participants with migraine. Atogepant is a medicine currently approved for the preventive treatment of adult patients with episodic migraine (0 to 14 migraine days per month) and is being studied for the preventative treatment of migraine globally. Topiramate is an approved medication for migraine prevention. This study is conducted in 2 periods. In Period 1, participants will be randomly put into 1 of 2 groups at the start of the study to receive atogepant or topiramate. In Period 2, eligible participants will receive atogepant. Approximately 520 participants aged 18 and older will be enrolled in this study in approximately 85 sites across the world. Participants will receive atogepant (and placebo for topiramate) or topiramate (and placebo for atogepant) for 24 weeks in Period 1. Both atogepant and placebo for atogepant are given as a tablet to take by mouth while topiramate and placebo for topiramate are given as a capsule to take by mouth. After 24 weeks, all eligible participants will receive atogepant for 52 weeks in Period 2. Participants are monitored for safety for 4 weeks after their last study treatment. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The safety and tolerability of the treatment will be checked by medical assessments, blood tests, checking for adverse events and completing questionnaires.
