Male or female participants of the following ages:\n\n 1. Cohort 1: Adults (≥ 18 years of age)\n 2. Cohort 2: Adolescents (12 to 17 years of age)\n 3. Cohort 3: Children 5 to 11 years of age\n 4. Cohort 4: Children 1 to \\< 5 years of age and \\>= 10 kg in weight\n2. Molecular diagnosis of AGS due to biallelic mutations in 1 of the following 5 genes: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, or SAMHD1, or due to a recognized dominant mutation in TREX1\n3. IFN score in peripheral blood \\> 2 standard deviations above the mean score of healthy controls measured on 3 occasions, approximately 2 weeks apart, during the 6-week Screening Period.\n4. Clinical syndrome consistent with AGS diagnosis based on clinical, CSF, and radiological findings. The following are examples of such findings (none of these are required for inclusion):\n\n 1. Early onset encephalopathy with psychomotor delay, spasticity, extrapyramidal signs, and microcephaly, the latter appearing in the first year of life\n 2. Calcifications particularly visible at basal ganglia level (putamen, pallidus, and thalamus), but also extending to the periventricular white matter\n 3. Cerebral white matter abnormalities\n 4. Cerebral atrophy\n 5. Important systemic symptoms in the early stages of the disease including irritability, feeding and sleeping difficulties, unexplained fevers, and the appearance of chilblain-like skin lesions on the fingers, toes, and ears\n5. Has a reliable caregiver to accompany the patient to all study visits. Caregiver must have frequent contact with patient and be willing to monitor the patient's health and concomitant medications throughout the study\n\nExclusion Criteria:\n\n1. Mutation in IFIH1, ADAR1, LSM11, or RNU7-1.\n2. Pre-/perinatal infections, in particular the TORCH complex (toxoplasmosis, rubella, cytomegalovirus, herpes simplex virus)\n3. Presence of other significant neurological disorders; brain tumor or other space-occupying lesion; history of severe head injury\n4. Clinically significant intercurrent illness, medical condition, physical or laboratory abnormality\n5. Autoimmune disease requiring treatment or management (quiescent rheumatoid arthritis, psoriasis, treated autoimmune thyroiditis, or controlled Type 1 diabetes are acceptable)\n6. History of human immunodeficiency virus (HIV), hepatitis B, or any active infection during Screening\n7. History of cancer within 5 years of Screening, with the exception of fully treated non-melanoma skin cancers\n8. Receipt of an experimental agent within 30 days or 5 half-lives prior to Screening, whichever is longer\n9. Prior treatment with an immunomodulator other than a JAK inhibitor within 6 months of Screening; patients taking JAK inhibitors for AGS must have been on a stable dose for one month prior to Screening\n10. Current treatment with a nucleoside reverse transcriptase inhibitor (NRTI) or other antiviral drug\n11. Receipt of systemic corticosteroids within 30 days prior to Screening\n12. Any vaccination within 30 days prior to Screening"}, 'identificationModule': {'nctId': 'NCT05613868', 'briefTitle': 'TPN-101 in Aicardi-Goutières Syndrome (AGS)', 'organization': {'class': 'INDUSTRY', 'fullName': 'Transposon Therapeutics, Inc.'}, 'officialTitle': 'A Phase 2a Study of TPN-101 in Patients With Aicardi-Goutières Syndrome (AGS)', 'orgStudyIdInfo': {'id': 'TPN-101-AGS-201'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Active, TPN-101', 'description': '100 mg/day to 400mg/ study investigational drug TPN-101 once daily for 48 weeks followed by 12 weeks of follow-up period.', 'interventionNames': ['Drug: TPN-101']}], 'interventions': [{'name': 'TPN-101', 'type': 'DRUG', 'otherNames': ['censavudine'], 'description': '100 mg/ day up to 400mg/day of TPN-101', 'armGroupLabels': ['Active, TPN-101']}]}, 'contactsLocationsModule': {'locations': [{'zip': '75015', 'city': 'Paris', 'country': 'France', 'facility': 'Laboratory of Neurogenetics and Neuroinflammation Imagine Institute - INSERM U1163', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}, {'zip': '27100', 'city': 'Pavia', 'state': 'Pavia', 'country': 'Italy', 'facility': 'Istituto Neurologico Casimiro Mondino', 'geoPoint': {'lat': 45.19205, 'lon': 9.15917}}, {'zip': '25123', 'city': 'Brescia', 'country': 'Italy', 'facility': "Presidio Ospedale dei Bambini [Children's Hospital]", 'geoPoint': {'lat': 45.53558, 'lon': 10.21472}}, {'zip': '20154', 'city': 'Milan', 'country': 'Italy', 'facility': 'SST Fatebenefratelli Sacco', 'geoPoint': {'lat': 42.78235, 'lon': 12.59836}}, {'zip': 'EH9 1LF', 'city': 'Edinburgh', 'country': 'United Kingdom', 'facility': 'Royal Hospital for Children and Young People', 'geoPoint': {'lat': 55.95206, 'lon': -3.19648}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Transposon Therapeutics, Inc.', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
