A Study to Test if TV-46000 is Safe for Maintenance Treatment of Schizophrenia

The primary objective of the study is to evaluate the long-term safety and tolerability of TV-46000. The primary safety and tolerability endpoint is the frequency of all adverse events, including serious adverse events. For new participants, the total duration of participant participation in the study is planned to be up to 80 weeks (including a screening period of up to 4 weeks, a 12-week oral conversion/stabilization stage [Stage 1], a 56-week double-blind maintenance stage [Stage 2], and a follow-up period [8 weeks]). For roll-over participants, the total duration of participant participation in the study is planned to be up to 64 weeks (including up to 56 weeks in the maintenance stage [Stage 2] and a follow-up period [8 weeks]). Participants who started Stage 2 who relapse or meet 1 or more of the withdrawal criteria should be invited to perform the Early Termination visit as soon as possible within 4 weeks of the last injection. Participants who withdraw from the study before completing the 56-week maintenance stage will have follow-up procedures and assessments performed at their follow-up visits. During the follow-up period, participants will be treated according to the investigator's judgment.

All participants will be treated with active drug.

Inclusion criteria

Participants Rolling Over from the Pivotal Efficacy Study TV46000-CNS-30072:

  • The participant must have participated in the pivotal efficacy study (Study TV46000-CNS-30072) without experiencing relapse events and without important protocol deviations.
  • If the participant was taking antidepressants or mood stabilizers in Study TV46000-CNS-30072, no dose changes or initiation of treatment with these medications will be permitted.
  • The participant, in the investigator's judgment, requires chronic treatment with an antipsychotic medication.
  • The participant is able to understand the nature of the study and follow protocol requirements, including the prescribed dosage regimens (oral and SC administration) and non-use of prohibited concomitant medications; can read and understand the written word in order to complete participant-reported outcomes measures; and can be reliably rated on assessment scales.
  • The participant has had a stable place of residence for the previous 3 months before the baseline visit in this study, and changes in residence are not anticipated over the course of study participation.
  • The participant has no significant life events (such as pending loss of housing, family status change, long travel abroad, surgery, etc) that could affect study outcomes expected throughout the period of study participation.
  • Women of childbearing potential and sexually active female adolescents must agree not to try to become pregnant, and, unless they have exclusively same-sex partners, must agree to use a highly effective method of contraception and agree to continue use of this method beginning 1 month before the first administration of study drug and for the duration of the study and for 120 days after the last injection of study drug.
  • The participant, if adult or adolescent male, is surgically sterile, or, if capable of producing offspring, has exclusively same-sex partners or is currently using an approved method of birth control and agrees to the continued use of this method for the duration of the study (and for 120 days after the last dose of study drug). Male participants with sex partners who are women of childbearing potential must use condoms even if surgically sterile. In addition, male participants may not donate sperm for the duration of the study and for 120 days after taking the study drug.

New Participants (Not Rolling Over from the Pivotal Efficacy Study TV46000-CNS-30072):

  • The participant has a diagnosis of schizophrenia
  • The participant has been responsive to an antipsychotic treatment (other than clozapine) in the past year based on investigator judgment (and discussions with family members, caregivers, or healthcare professionals as applicable).

  • The participant is able to understand the nature of the study and follow protocol requirements, including the prescribed dosage regimens (oral and sc administration) and non-use of prohibited concomitant medications; can read and understand the written word in order to complete participant-reported outcomes measures; and can be reliably rated on assessment scales.

  • The participant has no significant life events (such as pending loss of housing, family status change, long travel abroad, surgery, etc) that could affect study outcomes expected throughout the period of study participation.
  • The participant has a body mass index between 18.0 and 38.0 kilograms (kg)/square meter (m^2), inclusive.
  • Women of childbearing potential and sexually active female adolescents must agree not to try to become pregnant, and, unless they have exclusively same-sex partners, must agree to use a highly effective method of contraception and agree to continue use of this method beginning 1 month before the first administration of study drug and for the duration of the study and for 120 days after the last injection of study drug.
  • The participant, if adult or adolescent male, is surgically sterile, or, if capable of producing offspring, has exclusively same-sex partners or is currently using an approved method of birth control and agrees to the continued use of this method for the duration of the study (and for 120 days after the last dose of study drug). Male participants with sex partners who are women of childbearing potential must use condoms even if surgically sterile. In addition, male participants may not donate sperm for the duration of the study and for 120 days after taking the study drug.
