研究目的:

1. 主要目的是为了观察RRG-003(AAV1-hOTOF)在DFNB9先天性耳聋患者中给药的安全性和耐受性; 2. 次要目的是初步观察不同剂量RRG-003给药治疗DFNB9先天性耳聋患者的有效性,为后期临床试验的有效、合理剂量积累证据。  

Objectives of Study:

1. Main purpose is to observe the safety and tolerability of administration of RRG-003 (AAV1-hOTOF) in participants with DFNB9 congenital hearing loss; 2. Secondary purpose is to preliminarily observe the effectiveness of RRG-003 in the treatment of participants with DFNB9 congenital deafness, providing a basis for the effective and reasonable dosage of following clinical trials.

纳入标准:

1、受试者和/或其监护人须在试验前对本研究知情同意,并自愿签署书面的知情同意书,并愿意按照试验所规定的时间点进行随访; 2、能在监护人帮助下与研究者进行良好的沟通并遵守研究者的要求。对于无成熟语言能力的幼儿,能在监护人帮助下配合并遵守研究者的要求; 3、受试者和/或监护人对本试验有正确的认识,对获益有适当的期许; 4、年龄≥6个月,性别不限; 5、根据基因检测报告显示为DFNB9先天性耳聋患者:OTOF纯合或复合杂合突变; 6、听力学入选标准:重度及以上耳聋(≥65 dB); 7、满足耳科手术要求:如3个月内或筛查时通过CT扫描和/或MRI扫描排除如严重的中-内耳畸形、蜗神经发育异常等;并确认是否满足手术资格。

Inclusion criteria

1. Participants and/or their legal guardians must be fully informed about the study, voluntarily sign the informed consent form prior to the trial, and be willing to follow up at the time points specified in the trial; 2. Be able to communicate well with the researcher with the help of the guardian and comply with the requirements of the researcher. For children without mature language ability, they can cooperate and comply with the requirements of the researcher with the help of the guardian; 3. The subject's guardian has a proper understanding of the trial and an appropriate expectation of benefit; 4. Age >=6 months, without gender limitation; 5. According to the genitic test report, participants have either homozygous or compound heterozygous mutations in OTOF and were diagnosed with DFNB9 congenital deafness; 6. Audiology inclusion criteria: severe to complete deafness (>=65 dB); 7. To meet surgical qualification, severe middle - inner ear malformations, cochlear nerve abnormalities, etc., should be excluded by CT scan and/or MRI scan within 3 months or at screening.

排除标准:

1、基因诊断未提示OTOF突变; 2、其他类型的、不适合耳科手术的耳聋,如:3个月内CT/MRI检查扫描发现存在严重的中-内耳发育异常或畸形、蜗神经异常引起的耳聋等; 3、预先存在耳科疾病会妨碍计划的手术或干扰研究终点的解释,如:急-慢性中耳炎,梅尼埃病,听神经瘤、突发性耳聋听力未恢复等; 4、曾有药物滥用史,或6个月内接受过任何已知的耳毒性药物治疗(例如氨基糖苷类,顺铂,袢利尿剂等),或3个月内接受过抗病毒和免疫治疗; 5、严重免疫力低下者以及有严重免疫缺陷病史,包括HIV检测阳性,患有其他严重获得性、先天性免疫缺陷疾病,或有器官移植史; 6、患有严重的全身疾病患者或者严重的急性期疾病,如肺结核、处于活动期的乙型或丙型肝炎感染、活动性带状疱疹感染、胰腺炎、肾功能不全、或胃肠道溃疡等; 7、由外科医生、麻醉师或指定人员认定的手术或麻醉禁忌症患者。如过去6个月内发生心脑血管意外,包括心肌梗死、心力衰竭、心绞痛、脑血管意外或短暂性脑缺血发作及任何被研究者判断为不适于参加本试验的其他心脏疾病等;或对计划使用的药物过敏; 8、筛查时耳部(拟行手术的侧别)存在植入物(如:人工耳蜗); 9、伴有其它严重先天性疾病; 10、既往有明确的神经或精神障碍史,包括癫痫或痴呆,且目前病情未得到良好控制者; 11、研究者认为受试者不适合参加本临床研究的其它情况。 对于虽存在部分排除标准,但经评估后认为可耐受手术、风险可控的受试者,研究团队将在充分评估并与受试者/受试者监护人充分沟通风险与获益后,决定是否纳入研究。

Exclusion criteria:

1. Genetic diagnosis did not indicate OTOF mutations; 2. Other types of deafness that are not suitable for otological surgery, such as: the CT/MRI scan within three months found that there were severe middle inner ear dysplasia or malformations, cochlear nerve abnormalities caused deafness,etc.; 3. Preexisting ear diseases may hinder the planned surgery or interfere with the interpretation of research endpoints, such as acute chronic otitis media, Meniere's disease, acoustic neuroma, sudden deafness, and unrecovered hearing; 4. Have a history of drug abuse, or have received any known ototoxicity drug treatment (such as aminoglycosides, cisplatin, loop diuretics, etc.) within 6 months, or have received antiviral and immunotherapy within 3 months; 5. Individuals with severe low immunity and a history of severe immune deficiency, including HIV testing positive, other acquired or congenital immune deficiency diseases, or a history of organ transplantation; 6. Participants with severe systemic diseases or severe acute phase diseases, such as pulmonary tuberculosis, active hepatitis B or C infection, active herpes zoster infection, pancreatitis, renal insufficiency, or gastrointestinal ulcers; 7. Participants with contraindications to surgery or anesthesia identified by surgeons, anesthesiologists, or designated personnel. If a cardiovascular or cerebrovascular accident occurs within the past 6 months, including myocardial infarction, heart failure, angina pectoris, cerebrovascular accident or transient ischemic attack, and any other heart disease judged by the researcher to be unsuitable for participation in this trial; or if they are allergic to the planned medication; 8. During screening, implants (such as cochlear implants) are present in the ear (on the same side of the intended surgery); 9. Accompanied by other serious congenital diseases; 10. Has a clear history of neurological or mental disorders, including epilepsy or dementia, whose condition is not currently adequately controlled; 11. The researchers identify that the subjects are not suitable in this clinical study for any other situations. Note Regarding Exceptions: Participants meeting certain exclusion criteria may still be considered for enrollment if a thorough evaluation confirms surgical tolerance with acceptable risk, and after full communication of potential risks and benefits with the participant and/or their legal guardian.
