There are about 3709 clinical studies being (or have been) conducted in Thailand. 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.
The purpose of this study is to evaluate the efficacy, immunogenicity and safety of the 9-valent human papillomavirus (9vHPV) vaccine in men 20 to 45 years of age. The primary hypothesis tested after the primary database lock is that administration of a 3-dose regimen of 9vHPV vaccine will reduce the incidence of HPV 16/18/31/33/45/52/58-related oral persistent infection (6 months or longer) compared with placebo. There will also be an Extension Study to offer an opportunity to complete the 3 dose regimen of 9vHPV vaccine for participants who received placebo in the Base Study, or received less than 3 doses of 9vHPV vaccine in the Base Study.
The primary objective is to evaluate V114 in the prevention of vaccine-type acute otitis media (VT-AOM) and the safety of V114 with respect to the proportion of participants with serious adverse events (SAEs) through completion of the study. The primary hypothesis is that V114 is superior to no V114 in preventing VT-AOM as assessed by the incidence of VT-AOM.
The purpose of this study is to evaluate response to and safety of the HBV vaccine HEPLISAV-B in two study populations living with HIV: prior HBV vaccine recipients who are deemed non-responders and individuals who are naïve to HBV vaccination.
This study will evaluate the efficacy, safety, and pharmacokinetics of inavolisib in combination with palbociclib and fulvestrant compared with placebo plus palbociclib and fulvestrant in participants with PIK3CA-mutant, hormone receptor (HR)-positive, HER2-negative locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.
This study will assess the efficacy and safety of pembrolizumab plus enzalutamide plus Androgen Deprivation Therapy (ADT) versus placebo plus enzalutamide plus ADT in participants with mHSPC. The primary hypothesis is that in participants with mHSPC, the combination of pembrolizumab plus enzalutamide plus ADT is superior to placebo plus enzalutamide plus ADT with respect to 1) radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by blinded independent central review (BICR) and 2) overall survival (OS). As of 19-JAN-2023, the study was unblinded and all study participants stopped ongoing treatment with pembrolizumab/placebo and will continue to receive Standard of Care treatment until meeting protocol-specified discontinuation criteria if deriving clinical benefit. Safety analysis will be performed at the end of the study; there will be no further analyses for efficacy and electronic patient-reported outcome (ePRO) endpoints collected from participants beyond the IA1 cutoff date. All study participants will stop ongoing treatment with pembrolizumab/placebo. Exceptions may be requested for study participants who, in the assessment of their study physician, are benefitting from the combination of enzalutamide and pembrolizumab, after consulting with the Sponsor. All other study participants should be discontinued from study and be offered standard of care (SOC) treatment as deemed necessary by the Investigator. If enzalutamide as SOC is not accessible off study to the participant, central sourcing may continue. As of Amendment 04, disease progression will no longer be centrally verified, participants will only be assessed locally. As of Amendment 4, Second Course treatment is not an option for participants. There are currently no participants in the Second Course Phase.
The purpose of this study is to evaluate whether the addition of selexipag to standard of care treatment delays disease progression in children with Pulmonary Arterial Hypertension (PAH) in comparison to placebo.
The main aim of this study is to check for long-term side effects from ADYNOVI/ADYNOVATE prophylaxis in participants with haemophilia A when used under standard clinical practice in the real-world clinical setting.
This is a randomized, double-blind, placebo-controlled, parallel-group, international, multicenter, Phase 3 study to evaluate the efficacy and safety of repeat dosing of benralizumab 30 mg administered subcutaneously (SC) versus placebo in patients with severe nasal polyposis.
The primary objective of this study is to evaluate the antiviral activity of lenacapavir (formerly GS-6207) administered as an add-on to a failing regimen (functional monotherapy) in people living with HIV (PLWH) with multi-drug resistance (MDR).
The primary objective of this study is: To demonstrate the Purified Vero Rabies Vaccine - Serum Free (VRVg-2) is non-inferior to Verorab and Imovax Rabies vaccines in each age group (pediatric and adult populations) when administered as a 3-dose pre-exposure prophylaxis (PrEP) regimen, in terms of proportion of participants achieving a rabies virus neutralizing antibody (RVNA) titer greater than or equal to (>=) 0.5 IU/mL at Day (D) 42, i.e., 14 days after the 3rd injection (for Primary Series Cohort 1). The secondary objectives of this study are: First 1-5 with hypotheses testing will be evaluated sequentially - only if the previous objective is achieved, will the next objective be tested. To demonstrate that: - the observed proportion of participants in the VRVg-2 (VRVg) group at D42 is at least 99% with a lower limit of the 95% confidence interval (CI) of at least 97% - VRVg is non-inferior (NI) to Verorab and Imovax Rabies vaccines (Imovax) in each age group at D28 - 2-dose VRVg at D28 is NI to 3-dose Imovax at D42 in each age group - the observed proportion of participants in the VRVg group at D28 is at least 99% with a lower limit of the 95% CI of at least 97% - 2-dose Imovax at D28 is NI to 3-dose Imovax at D42 in overall participants (Cohort 1) To describe: - the immune response induced by VRVg versus Verorab and Imovax at D28 and at D42 in all age groups - the immune response induced by VRVg at D14 after a booster dose of VRVg administered at Month (M) 12 (Cohort 1) and between M24 up to M36 (Cohort 2) - the persistence of immune response at M6,12,18, and pre-booster between M24 up to M36 post-primary series vaccination (Cohort 2) - safety profile of VRVg versus Verorab and Imovax in primary series and after a booster dose of VRVg.
