入选标准
- •Adults, ≥ 18 years at time of informed consent (the minimum age for adult participants may be greater than 18 years of age in accordance with country-specific age definitions for adulthood). Participants must be capable of providing their own informed consent.
- •Diagnosed with SS by meeting the 2016 American College of Rheumatology (ACR)/EULAR Classification Criteria (Section 10.1, Appendix 1). If SS diagnosis is based on positive anti-Ro autoantibody, anti-Ro positivity must be confirmed by central lab.
- •Have an ESSPRI score of ≥ 5 at screening despite current or prior symptomatic or local therapy.
- •Have an ESSDAI score of < 5 at screening.
- •Positive for either anti-Ro autoantibodies or rheumatoid factor (RF), or both at screening (as per the definition of the standard central laboratory test). "
- •Residual salivary gland function as defined by whole stimulated salivary flow > 0.1 mL/min.
- •Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the [US, EU] General Data Protection Regulation [GDPR] in the EU) obtained from the participant prior to performing any protocol-related procedures, including screening evaluations. Participants must be able to self-complete Patient-Reported Outcomes (PROs) without assistance.
- •Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception from signing the informed consent form (ICF) and must agree to continue using such precautions through the end of the study or 3 months after last IP administration (if participant withdraws from study). Cessation of contraception after this point should be discussed with a responsible physician. The Investigator should evaluate the potential for contraceptive method failure (eg, noncompliance, recently initiated) in relationship to the first dose of IP. A woman of childbearing potential must have a negative highly sensitive serum pregnancy test at screening and must have a negative urine pregnancy test on the day of dosing prior to each dose of IP (Section 8.3.5). Additional requirements for pregnancy testing during and after study intervention are located in Section 8.3.
- •The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy. Highly effective methods of contraception (with a failure rate of < 1% per year when used consistently and correctly) include: · Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: - Oral - Intravaginal - Transdermal - Injectable · Progestogen-only hormonal contraception associated with inhibition of ovulation: - Oral - Injectable - Implantable · Intrauterine device (IUD) · Intrauterine hormone-releasing system (IUS) · Bilateral tubal occlusion · Vasectomized partner if partner is the sole sexual partner of the female subject of childbearing potential and that the vasectomized partner has received medical assessment of the surgical success). · Sexual abstinence Sexual abstinence is considered a highly effective method only if it is the preferred and usual lifestyle of the participant and the participant agrees to refrain from heterosexual intercourse from screening through the end of the study follow-up. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. A recommendation that the female partners (of childbearing potential) of male study participants should use a highly effective method of contraception other than a barrier method should be made. - Females of childbearing potential are defined as those who are not surgically sterile (surgical sterilization includes bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) or those who are not postmenopausal (defined as 12 - consecutive months with no menses without an alternative medical cause). - Vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the woman of childbearing potential study participant and that the vasectomized partner has received medical assessment of the surgical success.
- •Meets all of the following tuberculosis (TB) criteria: a. No history of latent or active TB prior to screening, except for latent TB with documented completion of locally appropriate treatment. b. No signs or symptoms suggestive of active TB from medical history or physical examination. c. No recent (≤ 12 weeks of screening) close contact with a person with active TB (close contact is defined as ≥ 4 hours/week OR living in the same household OR in a house where a person with active TB is a frequent visitor). d. Negative Interferon Gamma Release Assay (IGRA) test result for TB at screen unless previously treated as per Inclusion Criterion 11(a). Participants with an indeterminate test result can repeat the test, but if the repeat test is also indeterminate, they are excluded. If IGRA result by central laboratory is incongruent with recent local testing within 4 weeks prior to or during screening, a repeat assessment will be permitted. e. A chest radiograph (obtained during the screening period or any time within 12 weeks prior to screening) with no evidence of current active TB or other infection, or prior TB, malignancy, or clinically significant abnormalities suggesting an active process (unless due to SS)."
排除标准
- •Individuals with medical history of confirmed deep venous thrombosis, pulmonary embolism, or arterial thromboembolism within 2 years of screening.
- •History or presence of concomitant polymyositis or dermatomyositis or systemic sclerosis.
- •Active malignancy or history of malignancy within the last 5 years, except as follows: a. In situ carcinoma of the cervix treated with apparent success with curative therapy > 12 months prior to screening; OR b. Cutaneous basal cell carcinoma following presumed curative therapy.
- •Individuals who are pregnant or lactating or planning to become pregnant or donate eggs during the study or for 3 months after the last dose of IP (if participant withdraws from study).
- •Individuals who have a positive test for, hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) infection. A positive test for hepatitis B at screening is defined as: (1) positive for hepatitis B surface antigen (HBsAg); OR (2) positive for hepatitis B core antibody (HBcAb) or hepatitis B surface antibody (HBsAb) AND hepatitis B virus (HBV) DNA detected above the lower limit of quantification (LLOQ) by reflex testing by the central laboratory at screening. Individuals with a positive test for or a history of treatment for hepatitis C are excluded unless they have a documented sustained viral response to antiviral drugs approved for the treatment of hepatitis C, defined as an undetectable viral level of hepatitis C RNA at least 24 weeks following completion of therapy. Individuals with advanced fibrosis or cirrhosis due to hepatitis C should not be enrolled. "
- •Individuals with a positive test for SARS-CoV-2 on the day of randomization. Only those with symptoms suggestive of SARS-CoV-2 at randomization or significant exposure to (COVID-19) within 10 days prior to randomization, should be tested. Individuals with COVID-19 or COVID-19 exposure can delay randomization for 10 days and randomize once recovered; otherwise, they will need to rescreen.
- •Individuals with: a. Any opportunistic infections in the last 12 months (Section 10.3, Appendix 3), with the exception of a single episode of herpes zoster, non-invasive herpes simplex at any site, oral candidiasis, vaginal candidiasis, or cutaneous fungal infections, which are permitted within the prior 12 months unless of unusual severity. b. Active infections requiring systemic treatment at the time of screening or through randomization, or history of more than 2 infections requiring IV antibiotics within 12 months prior to screening.

- •Individuals with any severe or life-threatening cardiovascular (including vasculitis), respiratory, endocrine, gastrointestinal, hematological, neurological, psychiatric, or systemic disorder or any other condition that, in the opinion of the Investigator, would place the individual at unacceptable risk of complications, interfere with evaluation of the IP, or confound the interpretation of participant safety or study results.
- •Individuals who, in the opinion of the Investigator, are unable or unwilling to comply with protocol requirements (eg, active drug or alcohol abuse or for other reasons), including the completion of the DASPRI and PRO.
- •Individuals who have received live (attenuated) vaccine within the 4 weeks prior to randomization or plan to receive a live vaccine during their participation in the study. Non-live vaccines are permitted during study (see Inclusion Criterion 10 for COVID-19 vaccination); however, for participants planning to receive a vaccine within a month after Dose 1, completing vaccination prior to starting dosing should be considered by the Investigator.
- •Last administration of experimental or investigational biologic or oral agents (other than those listed in Exclusion Criterion 15) < 6 months prior to screening.
- •Individuals who have had previous treatment with any biologic B-cell-depleting therapy (eg, rituximab, ocrelizumab, inebilizumab, ofatumumab, or ianalumab) within 12 months or other B-cell-targeting therapy (eg, belimumab) < 3 months prior to screening."
- •Individuals treated with systemic corticosteroids for indications other than SS, RA, and SLE for more than a total of 2 weeks within 6 months prior to screening.
