Eligibility criteria

Inclusion

Participants who met original entry criteria in, and completed, the randomized 12-week study of NCT06221852.

Exclusion

No longer meeting original entry criteria from the randomized 12-week study of NCT06221852.
  • Change in brain redox nicotinamide adenine dinucleotide metabolites ratio (NAD+/NADH)24 weeks

    Change from baseline to week 24 in NAD+/NADH as measured by in vivo phosphorus magnetic resonance spectroscopy (31P-MRS).

  • Change in brain creatine kinase forward reaction rate (kf)24 weeks

    Change from baseline to week 24 in creatine kinase forward reaction rate (kf) as measured by 31P magnetization transfer (MT) MRS.

  • Change in insulin resistance24 weeks

    Change from baseline to week 24 of insulin resistance measured using the homeostatic model assessment of insulin resistance (HOMA-IR) using fasting blood glucose and insulin levels.

  • Change in psychotic symptoms24 weeks

    Change from baseline to week 24 in Positive and Negative Syndrome Scale (PANSS) total score. Scores range from 30-210; a higher score indicates a higher level of psychotic symptoms.

  • Change in depressive symptoms24 weeks

    Change from baseline to week 24 in Hamilton Rating Scale for Depression (HAM-D) total score. Scores range from 0-52; a higher score indicates a higher level of depression.

  • Change in mania symptoms24 weeks

    Change from baseline to week 24 in Young Mania Rating Scale (YMRS) total score. Scores range from 0-60. A higher score indicates a more severe illness.

  • Change in Clinical Global Impression (CGI) Scale24 weeks

    Change from baseline to week 24 in Clinical Global Impression (CGI) Scale. Scores range from 1-7; a higher score indicates higher severity of illness.
