Washington, DC Paid Clinical Trials

A Phase I trial to determine the safety of targeted immunotherapy with daratumumab (DARA) IV after total body irradiation (TBI)-based myeloablative conditioning and allogeneic hematopoietic cell transplantation (HCT) for children, adolescents, and young adults (CAYA) with high risk T-cell acute lymphoblastic leukemia (T-ALL) or T-cell lymphoblastic lymphoma (T-LLy). Pre- and post-HCT NGS-MRD studies will be correlated with outcomes in children, adolescents, and young adults with T-ALL undergoing allogeneic HCT and post-HCT DARA treatment. The study will also evaluate T-cell repertoire and immune reconstitution prior to and following DARA post-HCT treatment and correlate with patient outcomes. Read Less

Male adults with a confirmed diagnosis of prostate adenocarcinoma who meet criteria for localized high risk prostate cancer according to the NCCN guidelines and who are eligible for prostatectomy will be invited to participate. Criteria for high-risk prostate cancer include patients with preoperative prostate biopsy score of Gleason 8 (GS8) (Grade group 4 \[GG4\]) or higher. Patients also need to have a positive PSMA scan on 68-Ga-PSMA-11 PET/CT scan. Read Less

COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the disease (while patients are on low flow oxygen) with abatacept (active arm) combined with standard of care (SOC) improves recovery as compared with placebo + SOC (placebo arm). For both groups, intensification of immunomodulation will be provided as part of SOC in case of signs of disease progression (patient requires high flow nasal oxygen (HFNO) or more support) and/or if the patient has rapidly increasing oxygen requirement.

This randomized Type 1 hybrid effectiveness-implementation trial (N=186) will evaluate the effectiveness and implementation of a peer-delivered problem solving and behavioral activation intervention for adherence to LAI-PrEP/ART ("Peer Activate-LAI") compared to enhanced treatment as usual (ETAU) for a largely Black, substance-using population living with or at high risk for HIV. Specific aims are to: Aim 1: Evaluate the effectiveness of Peer Activate-LAI over 12-months on: a) LAI-PrEP/ART adherence (primary; receipt of all 6 maintenance injections within 7-day window); and b) substance use (secondary; WHOASSIST, urine toxicology); and c) Explore the moderating role of SRD-related factors (exploratory) Aim 2: To evaluate the implementation of Peer Activate-LAI including feasibility, acceptability, fidelity, and adoption guided by RE-AIM and Proctor's model,12,13 assessed using mixed methods, including a rapid ethnographic assessment of how SRD-related factors may affect implementation. Aim 3: To evaluate the economic viability of Peer Activate-LAI, including a) cost of implementation and sustainment, and b) cost-effectiveness from multiple stakeholder perspectives. This study will inform a potentially scalable, cost-effective model for facilitating effective adherence to LAI formulations of PrEP/ART within Black, substance-using populations with multiple minority identities who to date have had limited support for improving LAI adherence for HIV treatment and prevention.

This study will evaluate the safety and immunogenicity of the mRNA-1273.214 vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concerns (VOCs) in participants aged 6 months to \<6 years, when administered as a primary series in SARS-CoV-2 vaccine-naïve participants (Part 1) and a single booster dose (BD) given to participants who previously received 2 doses of the mRNA-1273 vaccine as a primary series (Part 2); and will evaluate the safety and immunogenicity of the mRNA-1273.815 vaccine, when administered as a BD in participants aged 6 months to \<6 years (Part 3) and when administered to SARS-CoV-2 vaccine-naïve participants aged 2 years to \<5 years of age (Part 4).

This is a Phase 3 extension, global, multicenter study to assess the long-term safety and tolerability of tolebrutinib in adult participants (aged ≥18 years) with RMS, PPMS, or NRSPMS who were previously enrolled in the Phase 2b LTS (LTS16004) or 1 of the 4 Phase 3 tolebrutinib pivotal trials (GEMINI 1 \[EFC16033\], GEMINI 2 \[EFC16034\], HERCULES \[EFC16645\], or PERSEUS \[EFC16035\]).

The main objective of the study is to assess efficacy and safety of dupilumab given up to 24 weeks in adults with CPUO. This is a master protocol which includes 2 parallel-treatment, double-blind, 2- arm Phase 3 staggered studies of similar design (Study A and Study B) in male and female participants aged 18 to 90 years with CPUO. Study B design may be adapted based on the results of Study A. For both Study A and B, after an up-to-4-week screening period, participants with severe pruritus (worst-itch numerical rating scale \[WI-NRS ≥7) will enter a 4-week run-in period during with a non-sedative antihistamine and an emollient (moisturizer). Participants with severe pruritus (WI-NRS ≥7) at baseline will be randomized (1:1) to be treated for 24 weeks (Study A) or 12 weeks (Study B) with either dupilumab or matching placebo in addition to their antihistamine and emollient regimen. The treatment period for both study A and B will be followed by a 12-week follow-up period. Read Less

The investigators will conduct a fully powered randomized controlled trial (RCT) to test the effect of a patient navigation intervention for Black/African American (B/AA) men who have sex with men (MSM) on PrEP initiation, adherence and retention in care. B/AA men who have sex with men (MSM) are disproportionately impacted by the HIV/AIDS epidemic in the United States. Pre-exposure prophylaxis (PrEP), a once daily medication, can dramatically reduce HIV acquisition risk. However, social and structural barriers have contributed to suboptimal PrEP initiation, adherence, and retention in care among B/AA MSM. Our prior NIH-funded pilot study (R34MH109371; MPI: Nunn, Chan, Mena) developed and evaluated an Intervention to Retain and Adhere MSM in PrEP (RAMP-IT-UP), a brief strengths-based patient navigation program to enhance PrEP care outcomes among young B/AA MSM. The intervention was found to be highly acceptable among B/AA MSM and demonstrated preliminary effectiveness. Compared to control participants, RAMP-IT-UP participants were statistically more likely to initiate PrEP and adhere to PrEP based on pharmacy fill data and PrEP blood levels. Additionally, RAMP-IT-UP participants were more likely to be retained in PrEP care at the 3-month and 6-month clinical visits. Specific Aim #1 of this study will conduct a fully powered randomized controlled trial (RCT to estimate the effectiveness of RAMP-IT-UP in improving PrEP adherence and care outcomes among B/AA MSM in real-world community health center settings (CHCs). Specific Aim #2 will estimate the cost-effectiveness of RAMP-IT-UP among B/AA MSM attending CHCs compared to standard of care. The investigators will also determine the cost-effectiveness of differing levels of intensity of navigation services to prevent HIV based on data collected in Specific Aim #1. Our goal is to develop a cost-effective intervention that enhances PrEP care outcomes and reduces HIV incidence for B/AA MSM which will be relevant for CHCs across the US. The long-term goal of this work is to decrease HIV incidence among B/AA MSM, which aligns with federal Ending the HIV Epidemic and National HIV/AIDS Strategy goals. This application is led by an experienced team of investigators with a proven track record conducting HIV, PrEP and disparities research in real-world clinical settings. Read Less

Phase 1/2, dose escalation and expansion study designed to evaluate the safety and tolerability of NVL-520, determine the recommended phase 2 dose (RP2D), and evaluate the antitumor activity in patients with advanced ROS1-positive (ROS1+) NSCLC and other advanced ROS1-positive solid tumors. Phase 1 will determine the RP2D and, if applicable, the maximum tolerated dose (MTD) of NVL-520 in patients with advanced ROS1-positive solid tumors. Phase 2 will determine the objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) of NVL-520 at the RP2D. Secondary objectives will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS), and clinical benefit rate (CBR) of NVL-520 in patients with advanced ROS1-positive NSCLC and other solid tumors.
