E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary goal is to investigate whether acute intranasal administration of oxytocin improves social cognition performances in bvFTD patients, as detected using experimental tasks. 1. Change from placebo condition in emotion recognition ability [ Time Frame: within two hours after IMP-1/IMP-2 administration, single-measurement/treatment (total of observations: 2)] 2. Change from placebo condition in empathy ability [ Time Frame: within two hours after IMP-1/IMP-2 administration, single-measurement/treatment (total of observations: 2)] 3. Change from placebo condition in time perception [ Time Frame: within two hours after IMP-1/IMP-2 administration, each testing day (total of observations: 4)] |
Testare l’effetto dell’ossitocina in confronto a placebo sul: i) riconoscimento delle emozioni ii) riconoscimento delle intenzioni altrui iii) percezione del tempo durante interazioni sociali nel paziente con diagnosi di variante comportamentale di demenza frontotemporale. |
|
E.2.2 | Secondary objectives of the trial |
The secondary goals are detecting whether oxytocin administration induces side effects and mood changes, as detected by participant’s and caregiver’s reports, and whether oxytocin’s effects depend on gender and/or number of administrations. In addition, we aim to monitor the changes of peripheral oxytocin levels following intranasal oxytocin administration. 1. Change from placebo condition in self-reported side effects associated with repeated acute administration of oxytocin 2. Change from placebo condition in Caregiver’s rating of patient’s side effects and mood change associated with repeated acute administration of oxytocin 3. Change from placebo condition in variation of oxytocin peripheral levels associated with acute administration of oxytocin 4. Change from placebo condition in variation of gender-related behavioral differences associated with acute administration of oxytocin |

Nello specifico si andrà a misurare l’eventuale presenza di: i) effetti collaterali associati al trattamento (ossitocina/placebo) riportati dal partecipante. ii) cambiamenti delle condizioni fisiche e/o dell’umore osservati dal caregiver successivamente al trattamento. iii) testare la sicurezza e la tollerabilità della somministrazione ripetuta in acuto di ossitocina/placebo iv) misurare variazioni del livello di ossitocina endogena a livello periferico v) misurare possibili differenze di genere nelle risposte alla somministrazione di ossitocina |

E.3 | Principal inclusion criteria |
- diagnosis of possible and probable behavioral variant FTD (bvFTD) based on clinical assessment, standard neuropsychological, functional, and neurobehavioral tests; - early and mild bvFTD (MMSE score=20); - stable (i.e., more than 2 months) medical treatment related to cognition or behaviour traditionally used for bvFTD, such as acetylcholinesterase inhibitors, memantine, anti-depressants, antipsychotic agents, other mood stabilizers, benzodiazepines. - ages 40-80; - both genders (women in menopausal status: females with amenorrhea for 12 months without an alternative medical cause. A high follicle stimulating hormone, FSH, level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy) - Males participants with female premenopausal partners must agree to use a double barrier method of contraception i.e., condom + diaphragm, condom or diaphragm + spermicidal gel or foam, and agree to maintain this throughout the study. Oxytocin nasal sprays has not been studied in pregnant or lactating women. - normal or correct-to normal vision - to be able to read and understand Italian language (the language used for the study instructions and Consent Form); - to be able to sign the consent form (MMSE=20, the semantic fluency, TMT A-B, and Digit Span scores should not be below 2SD from the mean scores); - availability of a caregiver who consents to participate into all study sessions and complete specific tests. (We consider a caregiver the person who spends at least 8 hours a day with the patient). |
• diagnosi di possible e probabile bvFTD (grado lieve/moderata - MMSE score=20); • trattamento farmacologico stabile (> 2 mesi) per bvFTD • età compresa tra 40-80 anni; • sia uomini che donne (donne in stato postmenopausa e non in età fertile) • capace di leggere e comprendere la lingua Italiana • essere in grado di firmare il modulo di consenso (MMSE=20, fluenza semantica, TMT A-B, e Digit Span non inferiori a 2SD dai punteggi medi) • availability of a caregiver who consents to participate into all study sessions and complete specific tests. |

E.4 | Principal exclusion criteria |
- Severe bvFTD (MMSE < 20) - Speech difficulties that in the opinion of the investigator would be incompatible with neuropsychology and safety assessments - Inability to sign the consent form - Medical or neurological disorders of the central nervous system apart from FTD - Any clinically significant hematological, endocrine, cardiovascular, renal, hepatic, gastrointestinal or neurological disease. If the condition has been stable for at least the past year and is judged by the investigator not to interfere with the patient's participation in the study, the patient may be included. - History of a myocardial infarction within the last two years or congestive heart failure. - Current uncontrolled hypertension - Current bradycardia (rate < 50 beats per minute/bpm) or tachycardia (rate > 100 bpm) - Current hyponatremia (Na <135 mEq/L) - Psychiatric disorders (depression, bipolar disorder or schizophrenia) - Hormonal therapy - Premenopausal women - Males refusing to use a double barrier method of contraception throughout the study. - Abuse of alcohol and drugs during the last 6 months - Severe hepatic or renal impairment - Ischemic cardiomyopathy - Diagnosis of cancer not in remission since at least 10 years - Known allergy to food additive and preservatives used for nasal sprays (E 216, E 218 and chlorobutanol hemihydrate) - Use of any investigational or experimental drug or device within the last 60 days prior to screening or within 5 half-lives of the experimental drug, whichever is longer. |

E.5 End points |
E.5.1 | Primary end point(s) |
On each testing day, in the 2 hr following substance administration, oxytocin induces a 20% improvement of social cognition performances in the context of a placebo-controlled trial: • Increased accuracy (number of corrected responses) and decreased latency (speed in ms to provide responses) to recognize emotions on the emotion recognition task compared to placebo • Increased accuracy (number of corrected responses) and reduced latency (speed in ms to provide responses) to recognize intentions during the empathy assessment task • Compared to placebo, a compression of subjective time perception during social interactions and a dilation of subjective time perception when alone, which would be indicative of patient’s increased sensitivity to social stimuli. |
In confronto alla somministrazione di placebo, la somministrazione di ossitocina porta a: i) Migliore accuratezza e maggiore velocità nel riconoscimento delle emozioni altrui; ii) Numero di risposte corrette maggiori nel test di empatia (capacità di riconoscere l’intenzionalità, la cognizione e lo stato affettivo altrui); iii) Maggiore variazione nella percezione soggettiva del tempo quando in presenza e in assenza di interlocutori. |

E.5.2 | Secondary end point(s) |
With respect to the secondary measures, we anticipate the following endpoints: • No difference between oxytocin and placebo with respect to frequency of sides effects indicated by the participant on a checklist on each testing day • Increase of positive affect as reported by the caregiver. • Increase of peripheral oxytocin concentration after oxytocin treatment • Stronger effect of oxytocin in males than females (because the levels are lower in baseline) Regarding the measurement of oxytocin concentrations, before and after the IMP administration, patients’ 9 ml blood samples will be collected and analyzed using the high-performance liquid chromatography method. The blood collection is a moderate-painful and relatively low-intrusive procedure. The blood sample will be collected by expert nurses 10 minutes before the IMP administration and at the end of the first experimental da |
In confronto alla somministrazione di placebo, la somministrazione di ossitocina porta a: i) assenza di differenze significative nella tipologia e nella frequenza di effetti collaterali ii) aumento dello stato affettivo positivo, come riportato dal caregiver iii) aumento dei livelli endogeni di ossitocina a seguito della somministrazione del farmaco con principio attivo iv) Nei tasks sperimentali, gli effetti dell’ossitocina saranno più forti nei maschi che nelle femmine. |
