There are about 2700 clinical studies being (or have been) conducted in Bulgaria. 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 trial was conducted as a prospective, randomized, multinational, multicenter, double-blind study in 4 parallel groups of patients.
A multinational, multicenter, randomized, Phase III, double blind, parallel group, placebo controlled study in subjects with Relapsing Forms of Multiple Sclerosis (RMS) to assess the efficacy, safety and tolerability of GA Depot, a long acting IM injection of glatiramer acetate, administered once every four weeks

The study consists of two parts, the Main Study and the Long Term Extension (LTE).
This is a clinical trial to determine the long-term safety and tolerability of an investigational drug in people with schizophrenia. Participants in the study will receive the drug being studied. This study is accepting male and female participants between 13 and 65 years old who have been diagnosed with schizophrenia and have completed Study SEP361-301 or SEP361-302. This study will be conducted in approximately 80 study centers worldwide. The treatment duration for this study is one (1) year.
The primary objective of the study is to assess the efficacy of aflibercept compared to laser in patients diagnosed with retinopathy of prematurity (ROP). The secondary objectives of the study are to assess the need for a second treatment modality, to assess the recurrence of ROP in the study and to assess the safety and tolerability of aflibercept.
Randomized, multi-center, double-blind, parallel-group, placebo-controlled study. Eligible subjects will be randomized to receive either 0.33 mg AD04 or placebo orally twice-daily for 24 weeks in conjunction with brief psychological counseling.

Extension study to provide ongoing long-term treatment with ASTX727 for participants who were benefitting from ASTX727 treatment in a previous Astex-sponsored clinical study of ASTX727 (including, but not limited to ASTX727-01 [NCT02103478], ASTX727-02 [NCT03306264], ASTX727-04 [NCT03813186]), and Food Effect Substudy to obtain survival information and long-term safety information. The purpose of the Food Effect Substudy is to evaluate the pharmacokinetics (PK) and safety of decitabine and cedazuridine when ASTX727 is given under fed (high-calorie/high-fat meal or low-calorie/low-fat meal) versus fasted conditions.

The purpose of this pilot study is to determine the safety, tolerability, and the maximum tolerated dose intranasal administration of temozolomide (TMZ) as a single agent in Treatment on the patients with GBM. Intranasal administration is a new method of treating brain tumours for the direct administration of drugs, inhibitors or viruses, with minimal involvement of the BBB. The investigators know the orally prescribed standard chemotherapy temozolomide (TMZ) is widely used to treat glioma tumours. Received evidence of safety and efficacy in a full cycle of preclinical trials (on GLP Standart) and tests of calculated doses of intranasal administration of TMZ in healthy volunteers. Intranasal administration of temozolomide is considered as GBM therapy, which provides direct access to a therapeutic dose of the drug into the brain (to the neoplastic process) with low toxicity
