An Exploratory Study to Evaluate Attention Biases in Adults With Multiple Sclerosis, Breast Cancer, and Lung Cancer

CT-100 is a platform that provides interactive, software based therapeutic components that may be used as part of a treatment in future software-based prescription digital therapeutics. One class of CT-100 components are Digital Neuro-activation and Modulation (DiNaMo) components. DiNaMo components target key neural systems (including but not limited to systems related to sensory-, perceptual-, affective-, pain-, attention-, cognitive control, social- and self-processing) to optimally improve a participant's health.

Targeted cognitive training is used to reduce symptoms relevant to multiple sclerosis (MS) and cancer. Biases to direct attention towards or away from certain stimuli can exacerbate a variety of symptoms in many different indications. For example, in chronic pain conditions, patients are more attentive to pain-related stimuli, which can lead to hypersensitization. Similarly, hypersensitivity to threat-related stimuli can exacerbate anxiety.

In this treatment, users are trained to re-orient attention away from negative stimuli, such as pain- or threat-related stimuli.
