    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Part A:
    The primary study objective in Part A was to select the dose of VTS-270
    to be used in Part B and Part C. Dose selection criteria included safety
    and tolerability including a thorough audiologic evaluation. Preliminary
    efficacy data was provided to the Dose Selection Committee (DSC) to
    assist, if necessary, in dose selection.

    Part B:
    The primary study objective in Part B is to evaluate, in a double-blind
    sham-controlled design, the progression of the neurologic
    manifestations of NPC1 disease following 52 weeks of treatment for
    subjects treated with VTS-270 compared to sham control, using the
    following assessments:
    •The NPC-SS composite which consists of the sum of 4 components of
    the Neimann Pick Type C Severity Scale (NPC-SS): ambulation, fine
    motor, cognition, and swallowing.
    •The blinded Clinician-Global Impression of Change (CGIC)

    Part C:
    The primary study objective in Part C is to evaluate the long-term safety,
    tolerability, and efficacy of VTS 270.
    Parte A:
    L'obiettivo primario dello studio nella parte A era selezionare la dose di VTS-270
    da utilizzare nella parte B e nella parte C. I criteri di selezione della dose includevano la sicurezza
    e tollerabilità, inclusa una valutazione audiologica approfondita. Preliminari dati di efficacia sono stati forniti al comitato di selezione delle dosi (DSC)
    per assistere, se necessario, nella selezione della dose.

    Parte B:
    L'obiettivo di studio primario nella parte B è di valutare, in doppio cieco
    la progressione delle manifestazioni neurologiche della malattia di NPC1 dopo 52 settimane di trattamento per soggetti trattati con VTS-270 rispetto al placebo.

    Parte C:
    L'obiettivo principale dello studio nella parte C è valutare la sicurezza a lungo termine, la tollerabilità ed efficacia di VTS 270.
    E.2.2Secondary objectives of the trial
    Part A:
    There are no secondary objectives for Part A.

    Part B
    The secondary objectives for Part B are divided into 2 categories: Key
    Secondary Objectives and Other Secondary Objectives.
    The key secondary objective for Part B is to evaluate the progression of
    the neurologic manifestations of NPC1 disease using the total NPC-SS
    score, excluding the hearing domain and auditory brainstem response
    (ABR) modifier results, following 52 weeks of treatment for subjects
    treated with VTS-270 compared to sham controls and the Caregiver
    CGIC.

    Part C:
    The secondary study objectives in Part C are to:
    1. Assess the safety and tolerability of the B. Braun Celsite Spinal Access
    Port utilized to administer VTS-270 (device safety and tolerability
    substudy).
    2. Assess the plasma and CSF PK of VTS-270 and trough HP-ß-CD
    concentration in subjects receiving the 900 mg dose of VTS-270 via the
    B. Braun Celsite Spinal Access Port (device PK substudy).
    Parte A:Non ci sono obiettivi secondari per la parte A.
    Parte B: L'obiettivo secondario principale per la parte B è valutare la progressione di
    le manifestazioni neurologiche della malattia di NPC1 dopo 52 settimane di trattamento per tutti i soggetti.
    Parte C:
    1. Valutare la sicurezza e la tollerabilità dell'accesso spinale B. Braun Celsite(sottostudio).
    2. Valutare la PK plasmatica e CSF di VTS-270 e tramite HP-ß-CD
    concentrazione in soggetti che ricevono la dose di 900 mg di VTS-270 tramite
    B. Porta di accesso spinale Braun Celsite (sottostudio PK del dispositivo).

    E.5 End points
    E.5.1Primary end point(s)
    Part A
    After all subjects in Part A have received 4 IT infusions at the randomized dose levels or sham LP, including 2 weeks of observation following the 4th dosing, all safety and efficacy data were provided to the DSC. The DSC included 2 neurologists with expertise in NPC1
    disease who were also allowed to participate, in an unblinded role, in the conduct of the study. The DSC also included a physician who was not allowed to be otherwise involved in the conduct of the study.
    The single dose selected for Parts B and C of the study was based on identification of the highest dose with acceptable safety and tolerability, including results of audiologic testing, as determined by the DSC. All data available through the 8- week time point was evaluated by the DSC in an unblinded fashion. These data included information on all AEs and SAEs through 8 weeks. Results of efficacy assessments were also provided to the committee.
    On the basis of these data, the DSC recommended a dose of 900 mg to be administered every 2 weeks for the remainder of the trial for subjects randomized to receive the active treatment. This dose was selected for its appropriate balance of safety, tolerability, and potential for efficacy. If at any time following the second dose of study drug during Part A of the study, a subject was reported to have clinically significant hearing loss [CTCAE grade 3 or higher], this was reviewed in an unblinded manner by the DSC, which could have made recommendations in light of other available ototoxicity data from the study. Such individuals were to have repeat pure tone audiometry (PTA) and distortion product otoacoustic emission DPOAE) testing as part of the hearing loss AE evaluation. Such recommendations could have included, for example, continuing on the current dose scheme, decreasing that subject's dose by 300 to 600 mg, decreasing all subjects in a specific dose cohort by 300 to 600 mg, discontinuing that subject from the study, or discontinuing that dose cohort.

    Primary Efficacy Endpoint for Part B:
    The co-primary efficacy analysis will be based on:
    • Change from baseline in NPC-SS composite score at Week 52 in the
    group treated with VTS-270 vs. the sham control group.
    • Blinded Clinician CGIC at Week 52 in the group treated with VTS-270
    vs the sham control group.

    Primary Endpoints in Part C:
    • The change from baseline to each assessment in a composite outcome
    that is the sum of the ambulation, cognition, fine motor, and swallowing
    components of the NPC-SS
    • The change from baseline to each assessment in total NPC-SS with the
    hearing domain and ABR modifiers removed
    • Proportion of responders (defined as no change or improvement on
    NPC-SS total score with hearing domain and ABR modifiers removed) at
    each assessment
    • Proportion of Blinded Clinician-CGIC (defined as a score of no change,
    minimally improved, moderately improved, or markedly improved) at
    each assessment compared to baseline
    • Summary of AEs, concomitant medications, physical examinations,
    audiologic examination, and clinical laboratories
    • Change from baseline in the EQ-5D-3L questionnaire at each
    assessment
    • Change from baseline to each assessment in each of the 9 clinical
    domains of the NPC-SS
    • Change from baseline to each assessment in the total NPC-SS with

    • The composite NPC-SS mean annualized rate of change (slope) from
    baseline to each assessment
    Parte A.
    Dopo che tutti i soggetti nella parte A hanno ricevuto 4 infusioni IT ai livelli di dose randomizzati o sham LP, incluse 2 settimane di osservazione dopo la 4a dose, tutti i dati di sicurezza ed efficacia sono stati forniti al DSC. Il DSC includeva 2 neurologi con esperienza nella malattia NPC1 ed anche un medico non coinvolto nella conduzione dello studio.
    La dose singola selezionata per le parti B e C dello studio era basata sull'identificazione della dose più alta con sicurezza e tollerabilità accettabili, inclusi i risultati dei test audiologici, come determinato dal DSC. Tutti i dati disponibili attraverso il punto temporale di 8 settimane sono stati valutati dal DSC in modo illimitato. Questi dati includevano informazioni su tutti gli eventi avversi per 8 settimane e le valutazioni di efficacia.
    Sulla base di questi dati, il DSC ha raccomandato di somministrare una dose di 900 mg ogni 2 settimane per il resto della sperimentazione per i soggetti randomizzati a ricevere il trattamento attivo. Questa dose è stata selezionata per il giusto equilibrio tra sicurezza, tollerabilità e potenziale efficacia.
    Il DSC ha raccomandato di ripetere i test di audiometria a tono puro (PTA) e di distorsione otoacustica del prodotto DPOAE come parte della valutazione della perdita uditiva. Tali raccomandazioni avrebbero potuto includere, ad esempio, il proseguimento del regime di dose attuale, la riduzione della dose di quel soggetto da 300 a 600 mg, la riduzione di tutti i soggetti in una coorte di dose specifica da 300 a 600 mg, l'interruzione di tale soggetto dallo studio o l'interruzione del trattamento dose di coorte.

    Endpoint di efficacia primario per la parte B:
    L'analisi di efficacia co-primaria si baserà su:
    • Modifica rispetto al basale del punteggio NPC-SS alla settimana 52 in gruppo trattato con VTS-270 rispetto al gruppo in placebo.
    • Valutazione in cieco del CGIC alla settimana 52 nel gruppo trattato con VTS-270 vs il gruppo in placebo.

    Endpoint primari nella parte C:
    • comparazione dei risultati rispetto al basale per la deambulazione, della cognizione, movimento e deglutizione - NPC-SS
    • comparazione dei risultati rispetto al basale - NPC-SS con dominio uditivo e modificatori ABR rimossi) ad ogni valutazione
    • Percentuale di responder (definita come nessun cambiamento o miglioramento su Punteggio totale NPC-SS con dominio uditivo e modificatori ABR rimossi) ad ogni valutazione
    • Percentuale per valutazioni in cieco-CGIC (definita come :nessuna modifica,minimamente migliorato, moderatamente migliorato o notevolmente migliorato) ad ogni visita rispetto al basale
    • Riepilogo di eventi avversi, farmaci concomitanti, esami fisici,
    esame audiologico e laboratori clinici
    • comparazione tra il basale con questionario EQ-5D-3L per ciascuna visita
    • comparazione tra il basale-NPC-SS per ciascuna visita.
    • comparazione tra il basale-NPC-SS con modificatore ABR
    • Tempo di peggioramento-NPC-SS
    • comparazione tra il basale ed ogni visita della media-NPC-SS

    hearing domain and ABR modifiers removed in the group treated with
    VTS-270 vs. the sham control group.
    • Proportion of Caregiver CGIC responders (defined as a score of no
    change, minimally improved, moderately improved or markedly
    improved) at Week 52 in the group treated with VTS-270 vs. the sham
    control group

    Other (non-key) secondary endpoints:
    • Summary of AEs, concomitant medications, physical examinations,
    audiologic examination, and clinical laboratories
    • Change from baseline in the EQ-5D-3L questionnaire at Week 52
    • Proportion of subjects in each group, treated for at least 6 months who
    qualified for the rescue option.
    • Change from baseline to Week 52 in each of the 9 clinical domains of
    the NPC-SS
    • Change from baseline to Week 52 in the total NPC-SS with hearing
    domain and ABR modifier included

    Parte B:
    Gli obiettivi secondari per la parte B sono divisi in 2 categorie: obiettivi secondari chiave e altri obiettivi secondari.
    L'obiettivo secondario chiave della Parte B è di valutare la progressione delle manifestazioni neurologiche della malattia NPC1 usando lo score totale NPC-SS, escludendo l'ambito uditivo e i risultati modificatori della risposta uditiva del tronco encefalico (ABR), dopo 52 settimane di trattamento per soggetti trattati con VTS-270 rispetto ai controlli con placebo e al CGIC del caregiver.

    Altri obiettivi secondari sono:
    1. Valutare la sicurezza e tollerabilità del VTS-270 somministrato IT via PL ogni 2 settimane rispetto al controllo con placebo
    2. Stimare la qualità di vita mediante EQ-5D-3L dopo 52 settimane di trattamento per soggetti trattati per 52 settimane con VTS-270 rispetto ai controlli con placebo
    3. Stimare inoltre l'efficacia del VTS-270 nel trattamento dei sintomi neurologici della sclerosi laterale amiotrofica confrontando soggetti trattati per 52 settimane con VTS-270 rispetto a controllo con placebo su:
    • Soggetti che hanno richiesto salvataggio dopo almeno 6 mesi di trattamento
    • I 9 ambiti principali dello score NPC-SS
    • Lo score totale NPC-SS (inclusi ambito uditivo e modificatore ABR)
    • Tempo trascorso fino a un incremento di un punto (peggioramento) dello score composito NPC-SS
    • Il tasso annualizzato di cambiamento (curva) dello score composito NPC-SS
    • Test timed up and go (TUG)
    • Test dei 9 pioli
    Parte C:
    Gli obiettivi secondari dello studio nella Parte C sono:
    1. Valutare la sicurezza e tollerabilità del port di accesso spinale B. Braun Celsite utilizzato per la somministrazione di VTS-270 (sottostudio di sicurezza e tollerabilità del dispositivo).
    2. Valutare la FC nel plasma e nel LCS di VTS-270 e attraverso la concentrazione di HP-ß-CD in soggetti che ricevevano la dose da 900 mg di VTS-270 tramite il port di accesso spinale B. Braun Celsite (sottostudio della FC del dispositivo).
