Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Part B: • Women of non-childbearing potential (surgically sterilized or post menopausal) or men, aged >=18 to = 18 to = 0.5 • Have confirmed granulin (GRN) mutation via genetic testing or historical records available for review by investigator • When engaging in sex with a woman of child bearing potential, both the male participant and his female partner must use highly effective contraception Part C • All participants who completed Part B of this trial are eligible for an 18-month OLE if the participant has no unresolved clinically significant TEAEs, where continued dosing may represent a risk to participant safety.

Exclusion criteria

Exclusion criteria: Part B • Have any history of clinically significant neurologic, psychiatric, endocrine, pulmonary, cardiovascular, gastrointestinal, hepatic, pancreatic, renal, metabolic, hematologic, immunologic, or allergic disease, or other major disorders • Have a history of malignancy, except fully resected basal cell carcinoma or other malignancies at low risk of recurrence • Have a clinically significant history of stroke, cognitive impairment due to causes other than FTD, seizure within 5 years of screening, or head trauma with loss of consciousness within 2 years of screening • Have a positive serum pregnancy test or are currently lactating or breastfeeding

Design outcomes

Primary

MeasureTime frame
Primary objective part B: - To investigate the safety and tolerability of multiple doses of DNL593 in participants with FTD-GRN Primary endpoint: - Incidence, severity, and seriousness of TEAEs during the 24-week double-blind period - Change from baseline in safety laboratory values, vital sign measurements, ECG results, Columbia-Suicide Severity Rating Scale (C-SSRS), and physical and neurological examination findings during the 24-week double-blind period Primary objective part C: - To investigate the safety and tolerability of multiple doses of DNL593 in participants with FTD-GRN up to 18 months Primary endpoint: - Incidence, severity, and seriousness of TEAEs during the OLE period - Change from baseline in safety laboratory values, vital sign measurements, ECG results, C-SSRS, and physical/neurological examination findings during the OLE period

Secondary

MeasureTime frame
Secondary objective part B: - To characterize the serum PK of DNL593 following multiple doses of DNL593 in participants with FTD-GRN - To characterize the concentration of DNL593 in CSF following multiple doses of DNL593 in participants with FTD-GRN Secondary endpoints: - DNL593 serum PK parameters (when feasible): o Cmax o tmax o Trough concentration (Ctrough) o AUClast o AUC from time 0 to the end of the dosing interval (AUC*) o t1/2 o Accumulation ratio - DNL593 CSF concentrations 24 hours postdose at Week 25 - DNL593 CSF:serum concentration ratio at Week 25 Secondary objective part C: - To characterize the serum PK of DNL593 following multiple doses of DNL593 in participants with FTD-GRN - To characterize the concentration of DNL593 in CSF following multiple doses of DNL593 in participants with FTD-GRN Secondary endpoints: - DNL593 serum PK parameters (when feasible): o Cmax o tmax o Ctrough o AUClast o AUC* o t1/2 o Accumulation ratio - DNL593 concentration 24 hours postdose at multiple time points - DNL593 CSF:serum concentration ratio at multiple time points
