Changwony was banned after testing positive for prohibited substances during the 2022 Volkswagen Prague Marathon.
Changwony, 34, was found to have 19-Norandrosterone, an anabolic steroid, and Triamcinolone Acetonide, a corticosteroid, in her system following an in-competition test conducted on May 8, 2022.
The AIU confirmed she did not have a valid Therapeutic Use Exemption (TUE) for either substance.
Her ban took effect on July 28, 2022,the date of her provisional suspension and expired on October 27, 2024.
All her results from May 8, 2022, have been disqualified.
"The AIU has banned Purity Changwony (Kenya) for 2 years and 3 months from 28 July 2022 for presence/use of prohibited substances (19-Norandrosterone, Triamcinolone Acetonide). DQ results from 8 May 2022,” read the AIU’s official statement.
Though the initial sanction could have extended to four years, Changwony received two reductions in her period of ineligibility.
One came from her prompt admission of the violation, and the other from her cooperation with the AIU under its case resolution framework, which involved a year-long engagement with authorities.
According to World Athletics’ anti-doping regulations, 19-Norandrosterone is classified as a non-specified substance banned at all times, while Triamcinolone Acetonide is a specified substance prohibited during competition.
The use of either substance without a valid TUE constitutes a violation of Anti-Doping Rules 2.1 and 2.2.
The AIU noted that no procedural irregularities were found in the sample collection or testing process.
While the AIU considers the decision final under Rule 8.5.6 of the Athletics Anti-Doping Rules, the ruling remains open to appeal.
The World Anti-Doping Agency (WADA) and the Anti-Doping Agency of Kenya (ADAK) have 15 days to contest the outcome before the Court of Arbitration for Sport (CAS) in Lausanne.
If appealed, Changwony would also retain the right to file a cross-appeal.
