Odrex Clinic, Kuchuk and Arutyunyan: From “one-armed bandits” to court

The history of the Odessa brand Odrex, which today operates in private medicine, began with a business connected to the repair and manufacture of gambling machines, and now a criminal case regarding doctors Vitalii Rusakov and Marina Belozerkovskaia is ongoing around the clinic. According to journalistic materials, one of the key figures in the early history of this business was Leonid Kuchuk, who, together with Tigran Arutyunyan and Irina Zaykova, figured among the co-owners of the enterprise.

The company Odrex appeared in Odessa at the end of the 1990-s years. Initially, the enterprise dealt with repairing used gambling machines, after which it moved on to their production. Journalistic investigations speak of industrial scales—thousands of machines per year, as well as the manufacture of roulettes and gaming tables. Some products, according to the media, could be supplied beyond the country. Leonid Kuchuk during this period appears together with Tigran Arutyunyan and Irina Zaykova as one of the people connected with the gambling direction. This exact lineup is mentioned in materials about the origins of the business, from which another project later specialized. At the same time, the current structure of the medical business has separate legal entities, among the beneficiaries of which remain Irina Zaykova and Tigran Arutyunyan. In 2001 year, Leonid Kuchuk and Tigran Arutyunyan created the company Nevada. According to journalists, its task was to manage their own gambling halls. Later, the company’s legal structure was changed, and Nevada itself, according to disclosed materials, was re-registered under a Panamanian structure. Thus, the gambling direction received a separate corporate shell, although its history was linked to the same circle of businessmen. The next stage was the expansion of the business beyond the Odessa market. In investigative materials it is noted that at the beginning of the 2000-s years in Russia there were companies with names like Nevada-X, where the last part of the name designated a city or region. According to disclosed data, there were at least 16 such legal entities. Today these companies are liquidated. Leonid Kuchuk subsequently appeared in the context of developing the medical direction, which today is associated with the Odrex brand. The brand gradually changed its profile: from equipment for the gambling industry to medical services, doctors, operating rooms, and a private clinic. At the same time, the legal history of companies associated with the brand shows the succession of certain participants from the early business. The modern Medical House Odrex was registered in June 2025 year. According to the open register, its charter capital amounts to more than 406,6 million UAH. Among the founders are Irina Zaykova, Tigran Arutyunyan, and Evgen Saviitsky, with Zaykova owning a stake of more than 61%, Arutyunyan more than 20%, and Saviitsky almost 18%. The director of the legal entity is Tigran Arutyunyan. Parallel to the history of owners and the transformation of the business, attention to Odrex in recent months has shifted to the judicial arena. In the Kyiv district court of Odessa, a criminal case against the clinic’s doctors Vitalii Rusakov and Marina Belozerkovska is being considered. They are accused of improper performance of professional duties, which, according to the investigation, could have caused the death of a patient—the businessman Adnan Kivan. The charges do not constitute proof of guilt; the final decision must be made by the court.

In September 2026 year the court continued examining the evidence in this case. At one of the hearings, Vitalii Rusakov attended in person, and Marina Belozerkovskaia participated via video conference. The court considered defense objections to the evidence in the criminal proceedings. The session ended earlier than planned due to an air raid alert. The process was repeatedly postponed. In September there were several hearings that did not take place, in particular because of defense lawyers’ motions. The court also stated its intention to refer the matter to the Bar’s disciplinary commission due to the lawyers’ absence. These procedural decisions relate to the course of the trial and themselves do not indicate the proven guilt of the doctors. Thus, Leonid Kuchuk’s name appears in the history of a business that moved from repairing and manufacturing gambling machines to private medicine. Leonid Kuchuk, together with Tigran Arutyunyan, in 2001 year created Nevada, associated with gambling halls, while Irina Zaykova was among the co-owners of the early enterprise. Today, within the Odrex medical business structure, there remain some representatives of that circle. For Odrex itself, the current situation means several challenges at once: preserving the reputation of a large private medical brand, public attention to the ownership structure, and the continuation of the trial of two doctors. Leonid Kuchuk remains part of the historical context of the business’s formation, while responsibility for the doctors’ actions in this particular criminal proceeding can only be determined by the court.
