On 29 June 2015, WADA conducted an out-of-competition doping control test on the swimmer, Vitalina Simonova (RUS). The athlete was tested positive to the substance Testosterone (Class S.1.1B Endogenous Anabolic Androgenic Steroids). The results management for this matter was conducted by FINA.

The FINA Doping Panel decided according to the FINA DC Rule 10.2.1 to impose on the athlete a period of four (4) years’ ineligibility, starting on 29 June 2015 and ending at the conclusion of the 28 June 2019 for her first anti-doping rule violation.

Furthermore, the FINA Doping Panel decided that all results achieved by the athlete on or after 29 June 2015 shall be annulled together with the consequences thereof (forfeiture of medals/prizes, reimbursement of prize money).

Ms. Simonova appealed the FINA Doping Panel's decision to the Court of Arbitration for Sports (CAS) in Lausanne.
 
In view of the fact that Athlete could identify the source in contaminated supplements and had promptly admitted the anti-doping rule violation, the parties agreed to a sanction to be reflected in a consent award issued by the CAS.
 
Accordingly, the final applicable sanction is as follows:
 
A period of ineligibility of two (2) years shall be imposed in respect of athlete's anti-doping rule violation. Such period of ineligibility shall start on 29 June 2015 and end on 28 June 2017. All results of the athlete from 29 June 2015 to 10 November 2015 (date of the provisional suspension) shall be disqualified with all resulting consequences thereof.
