This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
The US is currently going through an opioid crisis, and while Medication Assisted Treatments such as buprenorphine (BUP) have proved highly effective at stabilizing the neurobiology underlying acute withdrawal, they have been less effective at preventing longer-term relapse and adherence. This may be due to the fact that they do not fully engage the neural processes sub-serving the emotional control of sensitized negative mood and reward sensitivity during stress- and opioid-cue provocation, respectively. In contrast while the alpha2 agonist, guanfacine, may attenuate stress-provoked opioid craving by mediating top-down prefrontal control over sensitized dysphoria, the behavioral intervention, Mindfulness Oriented Recovery Enhancement (MORE) may reduce opioid cue-provoked craving by mediating top-down prefrontal control over hedonic dysregulation. Furthermore, while both interventions separately may prove effective as longer-term adjunctive therapies, they may offer greater efficacy together, providing a unique medication/behavioral combination able to target both stress and reward provocation mechanisms. To optimally test this hypothesis, a staged approach is proposed to first confirm the efficacy of both GXR and MORE, independently and combined (R61), prior to elucidating underlying neural mechanisms (R33). Using a 2 X 2 design, N=80 OUD individuals on BUP will be randomized to either 6-weeks of Guanfacine extended release (GXR; 3mgs, n=40) or placebo (PBO; n=40). Half of all participants in each group will then receive either weekly MORE, or a Support Group (SG) control, creating four intervention groups (Control Grp: PBO+SG, n=20); (GXR Grp: GXR+SG, n=20); (MORE Grp: PBO+ MORE, n=20); (Combined Grp: GXR+MORE, n=20). A pre- and post-laboratory study will be conducted before and after six weeks of intervention where participants will be randomly exposed to 3 personalized guided imageries (stress, opioid cue, neutral). Subjective measures of opioid craving, anxiety, mood, stress, emotional reappraisal, and heart rate will be collected before and after imagery exposure. Following milestone completion, an identical design is proposed in N=144 individuals, where participants will be exposed to imageries in the MRI scanner (R33). On the basis of prior research, it is hypothesized in that GXR will attenuate opioid craving and improve emotion regulation during stress, while MORE will demonstrate the same effects during opioid cue exposure. Combined GXR and MORE will also demonstrate additive or synergistic improvements compared with each intervention alone (R61). The effects of GXR on opioid cue- and MORE on stress-provoked opioid seeking will be explored. In the R33 component, it is hypothesized that GXR will improve regulatory and affective brain function during stress, and MORE will improve regulatory and reward function during opioid cue exposure. Combined GXR and MORE may improve regulatory function in an additive or synergistic manner (R33). Findings will help elucidate the efficacy and neural mechanisms underpinning a novel integrated pharmaco-behavioral therapy for OUD individuals maintained on BUP.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
