Autonomic Phenotype Before and After Akt Inhibition

This study has been withdrawn prior to enrollment.

Some Akt inhibitors have produced functional cardiovascular effects such as marked hypotension that may limit their clinical benefit. There are no current data on whether this autonomic failure presents in humans at clinically used doses. We will test the hypothesis that Akt inhibition causes an acute decrease in sympathetic tone and lowers blood pressure.

Condition Intervention
Diagnosis of Melanoma Behavioral: Autonomic Function Tests Other: supine and standing catecholamines

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Autonomic Phenotype Before and After Akt Inhibition: Akt Therapy for Melanoma Sub-study

Primary Outcome Measures:
  • Drop in systolic blood pressure before and after Akt treatment [ Time Frame: 8 hours ]

Enrollment: 0
Study Start Date: May 2012
Estimated Study Completion Date: May 2016
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients with Melanoma
Patients with Melanoma that are enrolled in a clinical trial at the Vanderbilt Ingram Cancer Center (VICC) including an arm with an oral Akt inhibitor
Behavioral: Autonomic Function Tests
Patients will undergo Autonomic Function testing (AFT) before and 8 hours after Akt Inhibition therapy. AFT includes: Supine & standing heart rate & blood pressure, 10 minute head up tilt, cardiac output, sinus arrhythmia, hyperventilation, sustained handgrip, valsalva manuever, and cold pressor test.
Other: supine and standing catecholamines
patients will have blood drawn from supine and standing catecholamines.


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients will have a diagnosis of Melanoma and be participating in a clinical trial with an arm using oral Akt therapy. Patients will be recruited from the Vanderbilt Ingram Cancer Center.

Inclusion Criteria:

  • Diagnosed with melanoma with a BRAF mutation and relapse following therapy with a BRAF inhibitor
  • Enrolled in a clinical trial through the Vanderbilt Ingram Cancer Center (VICC) including an arm with an oral Akt inhibitor
  • Able and willing to provide informed consent

Exclusion Criteria:

  • Factors which in the investigator's opinion would prevent the participant from completing the protocol, including poor compliance during previous studies or an unpredictable schedule
  • Unable to give informed consent
