Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Male or Female subjects ≥18 years to ≤60 years of age, inclusive
  • Body mass index (BMI) between 18 kg/m2 and 32 kg/m2, inclusive and weigh at least 50 kg
  • QT interval (Fridericia's correction \[QTcF\]); QTcF ≤ 450 msec for males and ≤ 470 msec for females at Screening and prior to dosing on Admittance Day -1
  • Willing and able to give signed Informed Consent and comply with the study visit schedule
  • In good general health as determined by the Investigator's review of medical history, concomitant medications, physical examination, clinical laboratory tests, and ECG evaluations
  • Male subjects must agree to use barrier contraception (male condom) and not donate sperm during the treatment period and for at least 3 months after the last dose of NM8074. Barrier contraception is required even with documented medical assessment of the surgical success of a vasectomy
  • Female subjects who are of childbearing potential must use highly effective contraception1 or acceptable contraception as defined below, starting at screening and continuing until at least 3 months after the last dose of NM8074. Female subjects must not donate ova during the screening and treatment periods and for at least 3 months after the last dose of NM8074
  • Highly effective contraceptive methods for female subjects are as follows:
  • a. Combined (estrogen and progesterone containing) hormonal contraception associated with inhibition of ovulation: i. Oral contraceptives (e.g., oral, injected, implanted) or intrauterine ii. Intravaginal iii. Transdermal b. Progesterone-only hormonal contraception associated with inhibition of ovulation: i. Oral ii. Injectable iii. Implantable c. Intrauterine Device d. Intrauterine hormone-releasing system e. Bilateral tubal occlusion/tubal ligation (or comparable procedure)
  • Women of Non-childbearing Potential
  • a. Postmenopausal: i. 12 continuous months of natural (spontaneous) amenorrhea without an alternative medical cause and a serum follicle-stimulating hormone (FSH) level
  • mIU/mL ii. 6 weeks after surgical bilateral oophorectomy with or without hysterectomy b. Post-hysterectomy
  • Sexual Abstinence Subjects who practice true abstinence, because of the subject's lifestyle choice (i.e., the subject should not become abstinent just for the purpose of study participation), are exempt from contraceptive requirements. Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception. For subjects who practice true abstinence, subjects must be abstinent for at least 6 months prior to screening and must agree to remain abstinent from the time of signing the Informed Consent Form until the end of study.
  • Same-sex Relationships For subjects who are exclusively in same-sex relationships, contraceptive requirements do not apply. A subject in a same-sex relationship at the time of signing the Informed Consent Form (ICF) must agree to refrain from engaging in a heterosexual relationship from the time of signing the ICF until the end of study
  • Has received the MenB Bexsero® vaccination against Neisseria meningitidis serogroup B (consisting of 2 intramuscular injections, 30 days apart) with the first injection at least 45 days prior to study drug initiation, and the second injection no later than 15 days prior to study drug initiation, and/or provides documentation of positive titer response precluding revaccination
  • +3 more criteria

You may not qualify if:

  • Subjects who plan to travel during the course of the study to endemic areas as per the Centers for Disease Control and Prevention (CDC) definition for meningococcal meningitis
  • Has a currently active systemic infection that requires antibiotic, antifungal, antiparasitic, or antiviral medications. Any infection prior to entry into the study must have been cured for 1 month prior to the Screening Visit
  • Positive QuantiFERON®-TB test indicating possible tuberculosis (TB) infection, active systemic bacterial, viral, or fungal infection within 14 days prior to dosing
  • Has a known history of meningococcal/pneumococcal/gonococcal disease

  • History of latent or active tuberculosis or exposure to endemic areas within 8 weeks prior to the tuberculosis test performed at screening
  • Clinically significant abnormalities in urine upon urinalysis to allow investigator discretion and to prevent disqualifications for minor findings of no significance such as mucus in the urine
  • Any of the following hematology tests: hemoglobin; total white blood cells (total WBC); absolute neutrophils; and platelets outside the laboratory reference range at Screening and Day -1
  • Abnormal urine tests: Clinically significant abnormalities in urine upon urinalysis" to allow investigator discretion and to prevent disqualifications for minor findings of no significance such as mucus in the urine
  • History of continuous topical/inhaled or systemic steroid use \> 1 month or history of any inhaled or topical immunosuppressive therapy within 90 days prior to study drug administration

Masking Details
This is a double-blind study (subjects and on-site medical/nursing staff at the study site are blinded to study drug/dose assignment). The pharmacy staff preparing the investigational products will not be blinded to NM8074 study drug assignment, but all other site staff, including the Investigator, will be blinded. Unblinding should only be considered for the safety of the subject.
Purpose
TREATMENT
Intervention Model
SEQUENTIAL
Model Details: Eligible subjects who meet the inclusion/exclusion criteria will be randomized on Day 1 to either NM8074 or placebo. The sentinel pair in each of the 5 dose cohorts will be randomized in a 1:1 ratio to receive NM8074 or placebo. The remaining subjects will be randomized in a 5:1 ratio to NM8074 to placebo. Dose escalation will occur in sequential cohorts once safety has been evaluated in the prior cohort.
