Relative Bioavailability of LY03010 Compared to Listed Drug

Overview

This is a randomized, multiple-dose, open-label, parallel-group study. Subjects will undergo screening evaluations to determine eligibility within 28 days prior to study drug administration. Approximately 280 eligible subjects will be randomized in a 1:1 ratio into 1 of 2 treatment groups. Subjects will be admitted to the clinical facilities the day before dosing (Day 0), and will be randomized and receive the first dosing on Day 1. Subjects will stay at site till Day 2 after PK collection. All subjects will return to the clinical sites at designated study days for dosing, PK sample collections and assigned clinical activities. All subjects randomized to LY03010 treatment group will receive the first dose of 351 mg LY03010 by IM injection on Day 1 in the deltoid muscle, followed by five (5) monthly dosing of 156 mg LY03010 in the gluteal muscle with the last dose on Day 141. All subjects randomized to SUSTENNA treatment group will receive the first dose of 234 mg SUSTENNA by IM injection on Day 1 in the deltoid muscle, and a second IM dose of 156 mg SUSTENNA on Day 8 in the deltoid muscle, followed by five (5) monthly IM dosing of 156 mg of SUSTENNA in the gluteal muscle with the last dose on Day 148. End of Study (EOS) visit for LY03010 treatment group will be on Day 169, 28 days after last dosing day; End of Study for SUSTENNA treatment group will be on Day 176, 28 days after last dosing. At EOS visit, subjects will complete the study after a series of assigned clinical assessments. A 30-day follow up call will be conducted by the clinical research staff to ensure participant's well-being.

This is a randomized, multiple-dose, open-label, parallel-group study. Subjects will undergo screening evaluations to determine eligibility within 28 days prior to study drug administration. Approximately 280 eligible subjects will be randomized in a 1:1 ratio into 1 of 2 treatment groups. Subjects will be admitted to the clinical facilities the day before dosing (Day 0), and will be randomized and receive the first dosing on Day 1. Subjects will stay at site till Day 2 after PK collection. All subjects will return to the clinical sites at designated study days for dosing, PK sample collections and assigned clinical activities. All subjects randomized to LY03010 treatment group will receive the first dose of 351 mg LY03010 by IM injection on Day 1 in the deltoid muscle, followed by five (5) monthly dosing of 156 mg LY03010 in the gluteal muscle with the last dose on Day 141. All subjects randomized to SUSTENNA treatment group will receive the first dose of 234 mg SUSTENNA by IM injection on Day 1 in the deltoid muscle, and a second IM dose of 156 mg SUSTENNA on Day 8 in the deltoid muscle, followed by five (5) monthly IM dosing of 156 mg of SUSTENNA in the gluteal muscle with the last dose on Day 148. On the day before the last dosing day visit (Day 140 for LY03010 treatment group and Day 147 for SUSTENNA treatment group), subjects will come to the clinical facility and stay at sites for 8 days for PK collection and other assigned activities. The schedules of assessments for each treatment group are listed in Table 2 and Table 3. End of Study (EOS) visit for LY03010 treatment group will be on Day 169, 28 days after last dosing day; End of Study for SUSTENNA treatment group will be on Day 176, 28 days after last dosing. At EOS visit, subjects will complete the study after a series of assigned clinical assessments. A 30-day follow up call will be conducted by the clinical research staff to ensure participant's well-being.

Be on a stable dose of oral antipsychotic medication(s) other than risperidone, paliperidone, clozapine, ziprasidone, or thioridazine for at least 4 weeks prior to screening. 6. Be clinically stable based on clinical assessments and a Positive and Negative Syndrome Scale (PANSS) total score ≤75 as well as a PANSS HATE (hostility, anxiety, tension and excitement) subtotal score <16 at screening. 7. Clinical Global Impression-Severity (CGI-S) score of 1 to 4, inclusive. 8. For patients with schizoaffective disorder only: Young Mania Rating Scale (YMRS) ≤12 and Hamilton Rating Scale for Depression, 21-item version (HAM-D-21) ≤12. 9. Body mass index (BMI) ≥17.0 and ≤ 37 kg/m2; body weight ≥ 50 kg. 10. All female patients (childbearing potential and non-childbearing potential) must have a negative pregnancy test result at both screening and baseline. Female patients must meet 1 of the following 3 conditions: (i) postmenopausal for at least 12 months without an alternative medical cause, (ii) surgically sterile (hysterectomy, bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal occlusion) based on patient report, or (iii) if of childbearing potential (WOCBP) and heterosexually active, practicing or agree to practice a highly effective contraception method of birth control. Highly effective methods of birth control include an intrauterine device (IUD), intrauterine hormone-releasing system (IUS), and contraceptives (oral, skin patches, or implanted or injectable products) using combined or progestogen-only hormonal contraception associated with inhibition of ovulation. A vasectomized male partner is an acceptable birth control method if the vasectomized partner is the sole sexual partner of the female patient and the vasectomized partner has received medical confirmation of surgical success. Highly effective methods of birth control must be used for at least 14 days prior to study drug dosing, throughout the study, and for at least 200 days after the end-of-study (EOS) visit to minimize the risk of pregnancy. 11. Sexually active fertile male patients must be willing to use acceptable contraception methods (such as double barrier methods of a combination of male condom with either cap, diaphragm or sponge with spermicide) from study drug dosing, throughout the study, and for at least 200 days after the EOS visit if their partners are women of childbearing potential.

If the results of clinical laboratory testing are outside normal reference ranges, the patient may be enrolled but only if these findings are determined not to be clinically significant by the Investigator. This determination must be recorded in the patient's source documents.
