NCT ID: NCT04895358 Active, not recruiting - Breast Neoplasms Clinical Trials

Study of Pembrolizumab (MK-3475) Plus Chemotherapy Versus Placebo Plus Chemotherapy for HR+/HER2- Locally Recurrent Inoperable or Metastatic Breast Cancer (MK-3475-B49/KEYNOTE-B49)

Start date: June 18, 2021
Phase: Phase 3
Study type: Interventional

The safety and efficacy of pembrolizumab plus the investigator's choice of chemotherapy will be assessed compared to placebo plus the investigator's choice of chemotherapy in the treatment of chemotherapy-candidate hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) locally recurrent inoperable or metastatic breast cancer. The primary hypotheses are that the combination of pembrolizumab and chemotherapy is superior to placebo and chemotherapy in regards to Progression-Free Survival (PFS) or overall survival (OS) in participants with programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 and ≥10.

Seamless Controlled Trial To Evaluate Safety And Immunogenicity of Chikungunya Vaccine in LatinAmerica and Asia

IVICHIK001
Start date: August 1, 2021
Phase: Phase 2/Phase 3
Study type: Interventional

This study has a Phase II with part A and part B and a Phase III with part C.

Part C will be randomized for immunogenicity subset and will be open label for safety cohort. The participants assigned to the control group from all parts (i.e, Part A, B and C) will be continuously followed up from the enrollment until the end of the study.

Start date: July 30, 2020
Phase: Phase 2
Study type: Interventional

The main purpose of this study is to evaluate the antitumor activity and safety of Lenvatinib (MK-7902/E7080) in children, adolescents, and young adults with relapsed or refractory solid malignancies after administration.

NCT ID: NCT04316221 Active, not recruiting - Growth Clinical Trials

Effects of Complementary Feeding of Eggs on Infant Development and Growth in Guatemala: The Saqmolo Study

Saqmolo
Start date: April 1, 2021
Phase: N/A
Study type: Interventional

The specific aims of this study are: In a randomized controlled trial, the investigators will evaluate the impact of daily egg consumption during the complementary feeding period in addition to the local standard of nutrition care (i.e., intervention group), compared to the local standard of nutrition care alone (i.e., control group) on the following outcomes, in infants that are ~6-month old at baseline: 1. Child development, as measured by global development scores (primary outcome) 2. Growth, as measured by anthropometrics (secondary outcome) 3. Diet quality, as measured by the World Health Organization infant and young child feeding indicators (secondary outcome) Hypothesis: The investigators hypothesize that daily consumption of eggs during the complementary feeding period, in addition to the local standard of nutrition care, will improve child development, growth, and diet quality compared to the local standard of care alone.

NCT ID: NCT04277325 Active, not recruiting - Clinical trials for Partner Relational Problems

Efficacy of Emotionally Focused Therapy Among Spanish Speaking Couples

E(f)FECTS
Start date: September 1, 2021
Phase: N/A
Study type: Interventional

70 couples (married or cohabiting) will be recruited across 5 countries (12-18 in each country: Argentina, Costa Rica, Guatemala, México, and Spain). After their entry into the study is confirmed, couples will be randomly allocated into one of two groups: intervention or control (no intervention). In each country, both groups will have equal number of couples. Couples in the intervention group will receive 20 sessions of Emotionally Focused couple Therapy (EFT). Couples in the control group will receive no intervention during the study period (they will receive a shorter intervention after the trial is over). Participants of both groups will fill questionnaires before allocation, during the intervention period and after the intervention period. The main outcomes will be couple attachment, couple satisfaction and dyadic adjustment. The original timeline for the study was to start in Argentina and Guatemala in February 2020, and the remaining countries in September 2020. The study started in February 2020 for Argentina and Guatemala, but in April 2020 the process was postponed due to mobility constrains during covid-19 crisis. During these two months, the process remained in the recruitment phase. Therefore, couples were not randomly assigned. Due to an improvement in the pandemic situation, the study started in Spain in September 2021.We expect the remaining countries will start during 2022. The study period for each couple will be around 6 months.

NCT ID: NCT04221945 Active, not recruiting - Clinical trials for Uterine Cervical Neoplasms

Study of Chemoradiotherapy With or Without Pembrolizumab (MK-3475) For The Treatment of Locally Advanced Cervical Cancer (MK-3475-A18/KEYNOTE-A18/ENGOT-cx11/GOG-3047)

Start date: May 12, 2020
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus concurrent chemoradiotherapy compared to placebo plus concurrent chemoradiotherapy in participants with locally advanced cervical cancer. The primary hypotheses are that pembrolizumab plus concurrent chemoradiotherapy is superior to placebo plus concurrent chemoradiotherapy with respect to progression-free survival and overall survival. Once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
