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.

Cytokine-induced killer (CIK) cells exhibit high proliferation rate and cytotoxic activity in vitro. The major effector cells are the CD3+CD56+ subset. The cytolytic activity of CIK cells being independent of MHC restriction implies feasibility in using CIK cells allogeneic to the tumors. Experiments to block the MHC class-I and -II pathways on tumors-RNA transfected DCs showed that only MHC class-I blocking led to a significant reduction of heterogeneous CIK cells cytotoxicity after the co-culture. The safety of CIK cells was demonstrated by the lack of cytotoxicity toward autologous as well as allogeneic normal cells. Co-culture of CIK cells with dendritic cells (DCs) has been reported by us and others in a myriad of cancer (e.g., cholangiocarcinoma, osteosarcoma, glioblastoma multiforme, multiple myeloma, hepatocellular carcinoma, pancreatic carcinoma, renal & colon carcinoma, murine leukemia & lymphoma showing enhancement of anti-tumor cytotoxicity of CIK cell in all. The co-culture of CIK cells with DCs were reported to decrease the number of professional regulatory/ suppressor T cells (Treg, CD4+CD25+ cells) and decrease the secretion of IL-10, an immune suppressor cytokine, whereas the cytotoxic activity against target cells increased. We have recently brought CIK cells through the preclinical phase (animal study) of human cholangiocarcinoma treatment. Cholangiocarcinoma (CCA), is a bile duct epithelial cancer endemic in the Northeast of Thailand, with an increasing incidence discernible in Europe and North America. Conventional treatments including surgery, chemotherapy, and radiation do not bring satisfactory survival due to anatomic location, presence of metastases, and high recurrent rates. These unsatisfactory outcomes urge to search innovative treatments such as immunotherapy. We reported the safety and efficacy of CIK cells in SCID mice model for cholangiocarcinoma. Several conditions of human CIK cells were examined using ex vivo cytotoxic assay and SCID mice pre-inoculated with human cholangiocarcinoma cells. We monitored the ex vivo cytotoxicity, tumor sizes and immunohistochemistry. Optimal tumor suppression was observed when CIK cells were pre-exposed to dendritic cells (DCs). Tumor-infiltrating human CD3+ cells were observed from day 2 - 14, but not in normal tissues elsewhere. These altogether indicated the specific homing of CIK cells to tumor mass. All animals did not exhibit any noticeable adverse reaction from the CIK treatments. The CD3+CD56+ cells are logical candidates for clinical trial while the DC-co-cultured CIK cells produced similar efficacy and more feasible for clinical application. With a complete array of in vitro and in vivo study, the next rational step is moving forward to phase I/II clinical trials for a number of specified solid tumors (i.e., cholangiocarcinoma, osteosarcoma, and glioblastoma multiforme, nueroblastoma) using the optimized autologous CIK cells. Subjects without prior exposure to or weaned for at least 3 months from chemotherapy can be recruited to maintain the integrity of their immunological system, a critical factor for a successful immunotherapy.
Demonstrate non-inferiority of the post-vaccination (Day 22) Hemagglutination inhibition (HI) Geometric Mean Titers (GMTs) of trivalent, inactivated, subunit influenza vaccine (TIV) over the corresponding GMTs of the comparator vaccine for all three strains, in healthy adults aged 50 years and above. Demonstrate non-inferiority of the percentages of subjects achieving seroconversion in antibody titers at Day 22 in the TIV group over the corresponding percentages of subjects in the comparator group for all three strains, in healthy adults aged 50 years and above.
This is a multicenter, double-blind, randomized, placebo-controlled dose response study, with an 8-week prospective baseline and an 18 week double-blind treatment period (including a 6-week titration phase and 12 week maintenance phase), followed by a 3-week blinded study drug taper period (for subjects leaving the study) or a 2-week blinded conversion period (for subjects who will participate in the open-label extension). The primary objective of this study is to determine the effective dose range of YKP3089 as adjunctive therapy for the treatment of partial seizures. The trial will also evaluate the safety and tolerability of YKP3089 in the partial epilepsy population.
Proliferative lupus nephritis (LN)is the predominant cause of morbidity and mortality in juvenile Systemic Lupus Erythematosus (SLE). Induction therapy with high-dose intravenous cyclophosphamide can improve renal outcomes, but considerably associated with infection. Although severe infection is the significant complication related to poorer prognosis for juvenile SLE patients in Asia, cyclophosphamide is still commonly used as the drug of choice for severe lupus nephritis. Euro-Lupus Nephritis Trial demonstrated low-dose intravenous cyclophosphamide regimen followed by azathioprine achieved good clinical results comparable with obtained high-dose regimen. There was lower number of severe infection episodes, but no significant difference. Recent studies applied low dose of cyclophosphamide (500 mg/m2/dose or 500 mg/dose)in young patients and showed good renal response. Low-dose intravenous cyclophosphamide regimen might promote non-inferior renal remission whereas decrease risk of serious infection and improve overall patient outcomes.
This study is an open label, non-randomized phase I single-armed study in women with metastatic breast cancer (MBC) who have previously undergone all available standard chemotherapy regimens. The purpose of the study is to estimate the pharmacokinetics (PK) after single dose and multiple dose of BP-C1, investigate interleukin levels during BP-C1 treatment and assess treatment response according to RECIST criteria.
This study will assess efficacy, safety , tolerability and PK in uncomplicated adult malaria patients with acute P. falciparum infection after single dose with KAE609 at 75 mg, 150mg, 225mg and 300mg/day
The purpose of this study is to evaluate the efficacy of Parecoxib and Ketorolac as a preemptive analgesia in patients undergoing lumbar spinal fusion.
Evaluate safety and tolerability of TIVa or TIVb vaccine in healthy children and adolescents 4 to 17 years of age.
This randomized, open-label, phase III study will be performed in patients with recurrent and/or metastatic head and neck cancer which has progressed after platinum-based therapy. The objectives of this trial are to compare the efficacy and safety of afatinib versus methotrexate.
