Detaillierte Beschreibung

This is a phase II/III multi-center study with two stages:

  • Stage 1 is designed to select the dose(s) for the confirmatory phase (DSCP) for alpelisib in Stage 2 and will comprise a 24-week open-label core phase in adult (≥18 years of age) and pediatric participants (6-17 years of age) with PIK3CA-mutated LyM, followed by an extension. After eligibility has been confirmed at screening, participants will be randomized in a 1:1 ratio to the different alpelisib doses according to their age. Depending on the results at the end of Stage 1 core phase, the Stage 2 will be opened to adult and/or pediatric participants or the study may be stopped.
  • Stage 2 is designed to confirm the efficacy and assess safety of alpelisib at the DSCP in participants with PIK3CA-mutated LyM and will comprise a 24-week randomized, double blind, placebo-controlled confirmatory phase in adult (≥18 years of age) and pediatric participants 6-17 years of age followed by an open-label extension. After eligibility has been confirmed at screening participants will be randomized in a 2:1 ratio to alpelisib or placebo.

Additionally, in parallel, Stage 2 will include a 24-week open-label core phase in pediatric participants 0-5 years of age followed by an extension, if pediatric participants will be enrolling in Stage 2.

Based on the results of the 24-week open-label core phase of Stage 1, the dose(s) for Stage 2 will be selected by Novartis in consultation with the Steering Committee (SC). During the 24-week randomized, double blind, placebo-controlled core phase of Stage 2, an Independent Data Monitoring Committee (DMC) will conduct periodic safety and efficacy reviews to assess the risk benefit profile of the treatment.

Stage 2: Percentage of participants with at least a 1-point improvement compared to baseline based on patient global impression of severity (PGI-S) scale at Week 24 of Stage 2 (adult and pediatric (6 - 17 years of age) participants)
Zeitfenster: Baseline, Week 24

PGI-S is a single item measure to assess the overall severity of a patient's condition. This single item instrument uses a 5-point rating scale, which ranges from 1 (no symptoms) to 5 (very severe). Lower scores indicate better health status. The percentage of participants with at least a 1-point improvement compared to baseline at Week 24 of Stage 2 in adult and pediatric (6-17 years of age) groups will be assessed
Baseline, Week 24
Stage 2: Percentage of participants with a radiological response at Week 24 of Stage 2 (pediatric participants 0-5 years of age)
Zeitfenster: Baseline, Week 24

Radiological response defined by achieving at least 20% reduction in the sum of target lesion volumes (1 to 3 lesions), assessed by MRI by a BIRC at Week 24, provided that none of the individual target lesions has at least 20% increase from baseline and in absence of progression of non-target lesions and without new lesions. The percentage of participants with a radiological response at Week 24 of Stage 2 in pediatric participants 0-5 years of age will be assessed
Baseline, Week 24
Stage 2: Change from baseline in patient global impression of change (PGI-C) scale (adult and pediatric (6-17 years of age) participants)
Zeitfenster: Up to approximately 8 years

PGI-C is a single item measure to assess the change in overall symptoms severity since the start of study. This single item instrument uses a 7-point rating scale, which ranges from 1 (very much improved) to 7 (very much worse). Lower scores indicate better health status. The change from baseline in PGI-C score will be assessed in adult and pediatric (6-17 years of age) participants
Up to approximately 8 years
Stage 2: Change from baseline in patient-reported outcomes measurement information system (PROMIS) profile domains(adult and pediatric (6-17 years of age) participants)
Zeitfenster: Up to approximately 8 years

The PROMIS-29 plus 2 Profile v2.1 (completed by adult participant) includes 29 items across domains of depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, ability to participant in social roles and activities, cognitive function abilities and pain intensity.

The PROMIS Pediatric-25 Profile v2.0 (completed by children over 8 years of age) and PROMIS Parent-Proxy-25 Profile v2.0 (completed by parents for children under 8 years of age) include 25 items across the domains of depressive symptoms, anxiety, physical function-mobility, pain interference, fatigue, and peer relationships and pain intensity All items (except the pain intensity item) use a 5-point Likert scale, which ranges from 1 (not at all) to 5 (very much). The pain intensity item is scored on a 0-10 numeric rating scale, where 0 represents "no pain" and 10 represents "worst imaginable pain".

The change from baseline in PROMIS domains will be assessed
Up to approximately 8 years
Stage 2: Change from baseline in investigator global impression of change (IGIC) scale (adult and pediatric (6-17 years of age) participants)
Zeitfenster: Up to approximately 8 years

The IGIC involves a single question that asks the investigator to rate the change in the patient's condition since the start of treatment or intervention, using a 7-point scale ranging from 1 (Very much improved) to 7 (Very much worse). The change from baseline in IGIC score will be assessed in adult and pediatric (6-17 years of age) participants
Up to approximately 8 years

Stage 1 and 2: Duration of response (DOR) in adult and pediatric participants who receive alpelisib
Zeitfenster: Up to approximately 8 years

DOR is defined as the time from first documented response until progression of LyM lesions by BIRC or death. This analysis only applies to participants who are on treatment with alpelisib (Stage 1 and 2) and who achieve response.
Up to approximately 8 years
Stage 1: Radiological response rate of alpelisib in adult and pediatric (6-17 years of age) participants
Zeitfenster: Baseline, Week 24

Radiological response defined by achieving at least 20% reduction in the sum of target lesion volumes (1 to 3 lesions), assessed by MRI by a BIRC at Week 24, provided that none of the individual target lesions has at least 20% increase from baseline and in absence of progression of non-target lesions and without new lesions.

The percentage of participants (adult and pediatric 6-17 years of age) with radiological response at Week 24 of Stage 1 will be assessed.
