Study Details

Study Description

Brief Summary

The goal of this Phase I/II clinical trial is to assess the safety and maximum tolerated training time of a self-administered computerized cognitive training (CCT) in individuals with cognitive dysfunction as a consequence of COVID-19 infection.

Post-Acute COVID-19 Post Acute COVID-19 Syndrome Cognitive Dysfunction Cognitive Impairment	Behavioral: CCT Long COVID	Phase 1/Phase 2

Detailed Description

A Phase I/II protocol is designed to determine the safety of a Computerized Cognitive Training (CCT) aimed at ameliorating the cognitive dysfunction often observed in persons with post-acute sequelae of COVID-19 (PASC). The Phase I/II trial also aims at establishing the maximum tolerated training time per session of the CCT and to explore the feasibility of such intervention. In Phase I, through a 3+3 design, a dose-escalation trial will be set. Participants will be tested across subsequent training blocks of 15 minutes each, reporting on the experienced fatigue or adverse effects after every block. The safe training dose will be set to a block before extreme fatigue or a notable adverse effect has been reported by two or more participants. Once a safety training time has been established, a group of participants will engage in a 15-day training effectiveness assessment. After an initial thorough pre-test assessment, the intervention protocol will start. An evaluation day and a training day will be interspersed so that participants will complete a total of 8 training sessions (days 1, 3, 5, 7, 9, 11, 13 and 15). After the final day of intervention, a post-test assessment session will be carried out.

Phase I: An open-label prospective Phase I dose-escalation study following a standard 3+3 rule-based up-and-down design without dose de-escalation will be followed. Phase II: An open-label prospective clinical trial to validate the minimum dosage and appropriate safety using the training time obtained in Phase I for the CCT along a 15-day training period with a 24-hour rest between sessions.Phase I: An open-label prospective Phase I dose-escalation study following a standard 3+3 rule-based up-and-down design without dose de-escalation will be followed.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Computerized Cognitive Training Individuals enrolled in Phase I and II will complete a Computerized Cognitive Training (CCT) based on an intervention with 15 different cognitive tasks in the form of games aimed at enhancing memory, attention, reasoning, perception and coordination skills. The CCT will be implemented in an app designed by CogniFit (CogniFit Inc., San Francisco, USA) to be used in tablets or mobile phones.	Behavioral: CCT Long COVID A 15-day training protocol in which every 48 hours participants' complete a series of different cognitive tasks in the form of games selected among a pool of 12 games from CogniFit (CogniFit Inc., San Francisco, USA) whose difficulty level is tailored to each individual by the a patented Individualized Training System™ (ITS) software that automatically chooses the activities and difficulty levels for each person in every session.
