Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Tolerability of Loxapine in patients with chemotherapy-induced neuropathic pain;Secondary Objective: Analgesic efficacy of Loxapine in patients with chemotherapy-induced neuropathic pain;Primary end point(s): This pilot study is a safety study primarily evaluating the tolerability of Loxapine in non-psychiatric patients. The primary endpoint is defined as the first occurrence of a (serious) adverse event leading to dose reduction or withdrawal of Loxapine ("event"). The Loxapine dosage with the lowest incidence of events will be identified.;Timepoint(s) of evaluation of this end point: The primary endpoints will be analyzed after all planned patients have finished the study (no planned interim analyses). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Regarding tolerability, the following secondary safety variables will be analyzed: - Number, type, and severity of (serious) adverse events ((S)AEs) - Cumulative incidence rates for (S)AE pattern of study participants - Individual (study participant-related) incidence of individual (S)AEs Regarding efficacy, the following secondary variables will be analyzed: - Individual (study participant-related) changes in pain severity (measured by using a 11-point numeric pain rating scale) in relation to treatment phase and Loxapine dosage - Assessment of the association between the pattern of events (primary endpoint) related to the individual pain level (Clinically relevant pain reduction is defined by an at least 30% decrease or an absolute decrease of two scale units (measured by using 11-point numeric pain rating scale) - Individual (study participant-related) changes in pain severity / characteristics (measured by painDETECT questionnaire) in relation to treatment phase and Loxapine dosage - Assessment of the association between the pattern of events (primary endpoint) related to individual changes in pain severity / charcteristics (measured by painDETECT questionnaire) - Individual (study participant-related) changes in the quality of life (12-item Short Form Health Survey (SF-12v2)) in relation to treatment phase and Loxapine dosage - Assessment of the association between the pattern of events (primary endpoint) related to the individual quality of life changes ((12-item Short Form Health Survey (SF-12v2)) - Individual (study participant-related) changes in anxiety and depression (HADS-D scale)) in relation to treatment phase and Loxapine dosage - Assessment of the association between the pattern of events (primary endpoint) related to the individual changes in anxiety and depression (HADS-D scale) - Assessment of the association between the pattern of events (primary endpoint) related to the individual changes analgesic co-me | — |
