Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Participants randomized to receive a single treatment with Ulthera system to lower face, submentum and neck on Day 1.
Device: Ulthera System
Participants will remain untreated until Day 90 and then receive a single treatment with Ulthera system to lower face, submentum and neck.
Device: Ulthera System
Participants will receive treatment with the Ulthera system which consists of three primary components: the control unit, handpiece and interchangeable transducers.
Proportion of Participants With at Least "Improved" in Lower Face, Submental and Neck Skin Laxity on Global Aesthetic Improvement Scale as Determined by the Blinded Live Evaluator (eGAIS) at Day 90 Compared to Baseline Photographs
Blinded live evaluator will use eGAIS to evaluate global aesthetic improvement in the facial appearance of participants. The GAIS is a 5-point scale (1-5), where: 1(very much improved); 2 (much improved); 3 (improved); 4 (no change); 5 (worse). Higher scores indicate a worse outcome.
Time frame: Day 90
Three Independent, Blinded Raters GAIS (rGAIS) Score in Lower Face, Submental and Neck Skin Laxity at Day 90 Compared to Baseline Photographs
Three independent, blinded raters will use rGAIS to evaluate global aesthetic improvement in the facial appearance of participants. The GAIS is a 5-point scale (1-5), where: 1(very much improved); 2 (much improved); 3 (improved); 4 (no change); 5 (worse). Higher scores indicate a worse outcome.
Time frame: Day 90
Treating Investigator's GAIS (iGAIS) Score in Lower Face, Submental and Neck Skin Laxity at Day 90 Compared to Baseline Photographs
Treating investigators will use the iGAIS to assess overall aesthetic improvement of the lower face, submentum, and neck. The GAIS is a 5-point scale (1-5), where: 1(very much improved); 2 (much improved); 3 (improved); 4 (no change); 5 (worse). Higher scores indicate a worse outcome. This outcome measure is prespecified for the Treatment Group only.
Time frame: Day 90
Participant's GAIS (pGAIS) Scores in Lower Face, Submental Skin and Neck Laxity at Day 90 Compared to Baseline Photographs
Participants will self-report using the pGAIS to assess overall aesthetic improvement of the lower face, submentum, and neck. The pGAIS is a 5-point scale (1-5), where: 1(very much improved); 2 (much improved); 3 (improved); 4 (no change); 5 (worse). Higher scores indicate a worse outcome. This outcome measure is prespecified for the Treatment Group only.
Time frame: Day 90
