The most common way to address this issue is by requiring volunteers to use contraceptives before, during, and a few weeks after the clinical trial. This work presents all the strategies used to promote contraception use and prevent pregnancy during the Alzheimer\u2019s Prevention Initiative Autosomal-Dominant Alzheimer\u2019s Disease (API ADAD) Colombia clinical trial. Two characteristics of this trial make it of special interest for closely monitoring contraception use. One is that the trial lasted more than 7\u2009years, and the other is that participants could be carriers of the E280A PSEN1 mutation, leading to a mild cognitive impairment as early as their late 30s.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>An individual medical evaluation to select the contraception method that best fits the volunteer was carried out during the screening visit, remitting to the gynecologist when necessary. All non-surgical contraception methods were supplied by the sponsor. Staff were trained on contraception counseling, correctly dispensing contraceptive drugs to volunteers, and identifying, reporting, and following up on pregnancies. Two comprehensive educational campaigns on contraception use were performed, and the intervention included all volunteers. In addition, volunteers were asked on an annual survey to evaluate the dispensing procedure. Finally, the effectiveness of these strategies was retrospectively evaluated, comparing by extrapolation the number of pregnancies presented throughout the trial with the General Fertility Rate in Colombia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 159 female volunteers were recruited. All strategies were implemented as planned, even during the COVID-19 contingency. Ten pregnancies occurred during the evaluation period (2015\u20132021). Two were planned; the rest were associated with a potential therapeutic failure or incorrect use of contraceptive methods for a contraceptive failure of 0.49% per year. Sixty percent of pregnancies led to an abortion, either miscarriage or therapeutic abortion. However, there was not enough data to associate the pregnancy outcome with the administration of the investigational product. Finally, we observed a lower fertility rate in women participating in the trial compared to the Colombian population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The lower rates of contraceptive failure and the decrease in the incidence of pregnancies in women participating in the trial compared to the Colombian population across the 7\u2009years of evaluation suggest that the strategies used in API ADAD Colombia were adequate and effective in addressing contraception use.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17407745241264217","type":"journal-article","created":{"date-parts":[[2024,8,15]],"date-time":"2024-08-15T00:28:15Z","timestamp":1723681695000},"page":"116-125","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Strategies to promote contraception use by female volunteers in Alzheimer\u2019s Prevention Initiative Autosomal-Dominant Alzheimer\u2019s Disease (API ADAD) Colombia trial"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2275-4263","authenticated-orcid":false,"given":"Christian","family":"Bustamante","sequence":"first","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan F","family":"Martinez","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Navarro","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margarita","family":"Lopera","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo","family":"Villegas","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sindy","family":"Duque","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Acosta-Baena","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia","family":"R\u00edos-Romenets","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3986-1484","authenticated-orcid":false,"given":"Francisco","family":"Lopera","sequence":"additional","affiliation":[{"name":"Neurosciences Group of Antioquia, University of Antioquia, Medellin, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"bibr1-17407745241264217","unstructured":"CIOMS.
