Exclusion criteria:

1. Clinical signs or symptoms suggestive of polyneuropathy of other causes, such as inflammatory neuropathies.
2. Any other neurologic or other disease that could better explain the participant’s signs and symptoms or that could cause signs/symptoms that could interfere with treatment or outcome assessments.
3. Diagnosis with CIDP variants not specified above per the 2021 EAN/PNS guidelines.
4. Known evidence of central demyelination or known history of myelopathy;
5. History or presence of significant medical/surgical condition including any acute illness or major surgery considered to be clinically significant or that could have a potential impact on safety/efficacy or study procedures in the opinion of the Investigator. A planned surgery during the treatment period may be allowed in consultation with the Medical Monitor.
6. Any other condition, including mental illness or prior therapy that in the opinion of the Investigator would make the participant unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likelihood of noncompliance with any study requirements.
7. Known complement deficiency or history of positive titer for anti-C1 antibodies.
8. Diagnosis of SLE or family history of SLE (defined as a parent, sibling, or child).
9. Diagnosis of an autoimmune disorder other than CIDP. Exceptions (other than SLE) may be allowed following consultation with the Medical Monitor and based on the Investigator’s clinical judgment.

11. Prior history (at any time) of N. meningitidis infection.
12. History of active malignancy within 5 years prior to Screening, except basal cell carcinoma of the skin, curatively resected squamous cell carcinoma of the skin, cervical carcinoma in situ curatively treated or low-grade prostate adenocarcinoma for which appropriate management is observation alone.

19. Liver test results elevated more than 2-fold above the ULN for GGT, bilirubin (total), AST, or ALT.
20. For female participants of childbearing potential, a positive serum pregnancy test during Screening or a positive urine pregnancy test (with confirmatory serum pregnancy test) on Part A Day 1.
21. An ANA titer ≥ 1:320, or positive for both ANA (any titer) and dsDNA, at Screening. If participants have these laboratory values after recent Ig treatment, they may be retested following discussion and agreement between the Investigator and the Medical Monitor to determine the appropriate retesting timeframe. Retesting may require rescreening.
22. Concurrent or previous use of the following medications within the time periods specified below: (1). Any anti-CD20 therapy (eg, rituximab) within 6 months (180 days) prior to Part A Day 1. (2) PLEX within 3 months (12 weeks) prior to Part A Day 1.

(4) If using any other current or prior medications for treatment of CIDP or that could affect immune function, the Investigator must consult the Medical Monitor to determine appropriate washout periods (if applicable) prior to Part A Day 1.
23. Currently or previously on complement inhibitors.
24. Currently on anti-FcRn agents. Participants who were previously on anti-FcRn agents including efgartigimod alfa and hyaluronidase-qvfc (VYVGART® HYTRULO) and took their last dose at least 5 half-lives or 90 days, whichever is greater, prior to Part A Day 1 may be considered after review and approval by the Medical Monitor.
25. Participation in another clinical trial of an investigational drug within 90 days or 5 half-lives of the investigational agent (whichever is longer) prior to Part A Day 1.

随机方法(请说明由何人用什么方法产生随机序列):

在阶段A中确认对DNTH103产生应答的受试者随后通过IRT系统以1:1:1的比例被随机分配至3个治疗组之一:安慰剂组、DNTH103 300 mg组或DNTH103 600 mg组。将根据阶段A入组前的既往用药情况对随机化进行分层。 阶段B是双盲期,受试者、研究者、研究工作人员、结局评估者和申办者对研究治疗保持盲态。

Randomization Procedure (please state who generates the random number sequence and by what method):

Subjects with confirmed responses to DNTH103 in Part A were subsequently randomized in a 1:1:1 ratio to one of three treatment groups: placebo, DNTH103 300 mg, or DNTH103 600 mg by an IRT system. Randomization will be stratified according to prior medication status before Part A enrollment.In Part A, all subjects received open-label treatment with DNTH103 for up to 13 weeks. Subjects with confirmed responses to DNTH103 in Part A were subsequently randomized in a 1:1:1 ratio to one of three treatment groups: placebo, DNTH103 300 mg, or DNTH103 600 mg by an IRT system. Randomization will be stratified according to prior medication status before Part A enrollment (IVIg or SCIg [with or without oral corticosteroids], oral corticosteroids alone, refractory, or treatment-naive). Part B of the study is a double-blind period during which subjects, investigators, study staff, outcome assessors, and the sponsor remain blinded to study treatment.
