Lundbeck updates on clinical phase III study for Lu AF35700 in Treatment-Resistant Schizophrenia
- Lu AF35700 did not show statistical superiority versus conventional therapy on the primary endpoint (change in Total PANSS) in patients with treatment-resistant schizophrenia (TRS)
- Lu AF35700 showed good anti-psychotic effects, was well-tolerated and safe at 10 mg and 20 mg dosages in the study
- Further analysis of the data is ongoing
Valby, Denmark, 25 October 2018 - H. Lundbeck A/S (Lundbeck) today announced that DAYBREAKi, the first phase III study for Lu AF35700, an investigational, novel, once-daily, oral antipsychotic drug candidate for the potential treatment of treatment-resistant schizophrenia (TRS), did not meet the primary endpoint of statistical superiority vs conventional therapy.
Lu AF35700 was safe and generally well-tolerated in the study with no unexpected adverse events reported.
“TRS constitutes the highest burden of disease within schizophrenia for patients, their families and society and we had with Lu AF35700 hoped to show superiority against conventional therapy”, says Anders Gersel Pedersen, Executive Vice President, Research and Development at Lundbeck; “this is a setback for patients with schizophrenia, but we will continue to advance our pipeline of innovative therapies to meet the needs of patients suffering from psychiatric and neurological diseases.”
DAYBREAK was a multinational, double-blind, randomized, active-controlled phase III study that evaluated the antipsychotic efficacy, safety and tolerability of Lu AF35700 compared to an active-controlled arm over ten weeks in 964 patients with TRS.
About DAYBREAK I
The safety and efficacy of Lu AF35700 in patients with TRS was assessed in a 10-week, double-blind, randomised, active-controlled trial. The target TRS population for randomization was patients who met the DSM-5 criteria for schizophrenia who experienced ongoing psychotic symptomatology and demonstrated a lack of satisfactory clinical improvement to at least two different antipsychotics given at an adequate dose and duration.
The study included a single-blinded prospective treatment period of patients with persistent psychotic symptomatology who had at least one adequate and well-documented antipsychotic treatment trial without a satisfactory clinical improvement were treated for 6 weeks with either risperidone (4mg to 6mg/day) or olanzapine (15mg to 20mg/day) to confirm their resistance to antipsychotic treatment.
Patients who did not fulfil the pre-specified response criteria in the prospective treatment period were considered treatment-resistant and were eligible to enter the double-blind treatment period were patients were randomly assigned to 10 weeks of daily treatment with either Lu AF35700 10mg (n=235), Lu AF35700 20 mg (n=232) or to continued treatment with risperidone or olanzapine (n=230).
The primary efficacy endpoint was change from randomisation to Week 10 of the double-blind treatment period in PANSS total score.
About Lu AF35700
Lu AF35700 is an antagonist at dopaminergic, serotonergic, and α adrenergic receptors. Unlike all currently available antipsychotics, Lu AF35700 has higher affinity for the human dopamine D1 receptor than it has for the human dopamine D2 receptor. In TRS, the higher ratio of dopamine D1 vs. D2 receptor activity is hypothesized to result in a beneficial efficacy profile and a tolerability profile without the troublesome side effects associated with extensive dopamine D2 receptor blockade, such as extrapyramidal symptoms.
In November 2015, FDA granted Fast Track designation for Lu AF35700 — a first important step to ensure a potential expedited approval of the compound.
About treatment-resistant schizophrenia (TRS)
Treatment-resistant schizophrenia (TRS) is broadly defined in clinical guidelines as no or minimal clinical improvement in target schizophrenia symptoms following treatment with ≥2 anti-psychotic treatments of adequate dose and durationii, [iii], [iv], [v], [vi]. About one-third of patients with schizophrenia have TRS with persistent core positive symptoms of at least moderate severity despite treatment with antipsychoticsvii, [viii], [ix]. TRS is among the most highly disabling psychiatric disorders for both patients and caregivers, and imposes the greatest impairment in the patients’ community functioning and psychosocial adjustmentx, [xi]. TRS is associated with poor prognosis and functional outcomes, and individuals with TRS are at increased risk of hospitalization, unemployment, homelessness, aggression, imprisonment, substance abuse, violent victimization, and suicidexii, [xiii], [xiv].
