Eligibility Criteria
You may not qualify if:
- have an authorized parent/legal guardian who understands the nature of the study and who provides written informed consent if the study subject is younger than 18 years of age. Additionally, each subject must provide assent to the study;
- be fluent in English;
- be 12 to 21 years of age, inclusive;
- be using a medically accepted means of contraception (i.e., oral contraceptives and barrier methods (diaphragm or condom), medroxyprogesterone acetate injectable suspension, abstinence) if female and of menarche. Oral contraceptives alone are not acceptable means of contraception because concomitant use of topiramate and low estrogen oral contraceptive pills may lead to oral contraceptive failure;
- have a diagnosis of bipolar I disorder in a current manic or mixed episode, in addition to a cannabis use disorder (which includes abuse or dependence) within 28 days prior to screening, as determined by the WASH-U-KSADS;
- have an initial YMRS total score of \>16 at screening and baselines;
- use cannabis a minimum of twice per week on average during the 28 days prior to screening.
- have a known history of mental retardation;
- are acutely intoxicated, and thus impaired;
- have manic or depressive symptoms resulting entirely from acute medical illness or acute intoxication or withdrawal from drugs or alcohol, as determined by medical evaluation and rapid symptom resolution;
- have clinically significant alcohol or other drug withdrawal symptoms, as determined by vital signs, The Clinical Institute Withdrawal Assessment for Alcohol Scale - Revised (CIWA-Ar)24, and physician interview;
- have any unstable medical or neurological illness as determined by a study physician;
- have laboratory abnormalities \>3 times upper limits of established normal values;
- as females, have a positive serum (screening and week 16) or urine pregnancy test (at baseline and weeks 1-16), are lactating, or are not practicing a reliable form of birth control;
- have a history of nephrolithiasis, since topiramate has been associated with an elevated risk of kidney stones;
- +9 more criteria
