There are about 371 clinical studies being (or have been) conducted in Guatemala. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study has a Phase II with part A and part B and a Phase III with part C. This Adaptive seamless design will prospectively include planned modifications and incorporate both dose selection (parts A and B) and confirmation of the selected dose (part C) based on the accumulation of subjects' data within the entire study period as shown below. 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.
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. Participants will be enrolled into initial tumor-specific cohorts which will be expanded based on observed response.
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.
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.
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.
The purpose of this study is to assess the efficacy and safety of treatment with definitive chemoradiotherapy (dCRT) + pembrolizumab (MK-3475) compared to treatment with dCRT + placebo with respect to Event-free Survival (EFS) and Overall Survival (OS) in: - participants whose tumors express Programmed Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10 - participants whose tumors express PD-L1 CPS ≥1 - all participants The primary study hypotheses are that dCRT+ pembrolizumab is better than dCRT + placebo with respect to: - EFS in participants whose tumors express PD-L1 CPS ≥10 - EFS in participants whose tumors express PD-L1 CPS ≥1 - EFS in all participants - OS in participants whose tumors express PD-L1 CPS ≥10 - OS in participants whose tumors express PD-L1 CPS ≥1 - OS in all participants
The purpose of this extension study is to evaluate maintenance of HiSCR response in either continuous or interrupted therapy (using a randomized withdrawal period) of two dose regimens and to assess long-term efficacy, safety and tolerability of secukinumab in subjects with moderate to severe hidradenitis suppurativa completing either of the 2 Phase III studies. This is an expanded access trial for the core trials AIN457M2301 (NCT03713619) and AIN457M2302 (NCT03713619).
A Prospective, Multicenter, Non-Interventional Study of Primary Data Collection, Designed to Describe the Diagnosis, Anti-Cancer Treatment and Clinical Outcomes in Patients with Breast Cancer in Latin America.
The purpose of this study is to assess the efficacy and safety of treatment with olaparib (MK-7339) in combination with pembrolizumab (MK-3475) in adults with previously treated, advanced (metastatic and/or unresectable) Homologous Recombination Repair Mutation (HRRm) and/or Homologous Recombination Deficiency (HRD)-positive solid tumors.
This study will evaluate the safety and efficacy of ertugliflozin (MK-8835) in pediatric participants with T2DM on metformin with/without insulin. The primary hypothesis of the study is that the addition of ertugliflozin reduces hemoglobin A1C (HbA1C) more than the addition of placebo after 24 weeks of treatment.
