Brief Summary
This is a Phase 1b, randomized, double-blind, placebo-controlled, dose range finding study to assess the safety, tolerability, pharmacodynamics (PK) and pharmacokinetics (PD) of RLS-0071 in healthy ad...
Detailed Description
The inclusion of a double-blind design allows a comparison between subjects receiving RLS-0071 and placebo subjects who are experiencing the same procedures and restrictions in an unbiased manner. The...
Eligibility Criteria
Inclusion
- Inclusion criteria:
- Age 18 to 55 years, inclusive, at the time of Screening
- Female subjects of childbearing potential must agree to use a highly effective contraceptive method from Screening until 30 days after the last investigational medicinal product (IMP) intake and have a negative pregnancy test at Screening (blood test). The following contraceptive measures can achieve a failure rate of less than 1% per year when used consistently and correctly and are considered highly effective measures:
- combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral / intravaginal / transdermal)
- progestogen-only hormonal contraception associated with inhibition of ovulation (oral / injectable / implantable)
- intrauterine device
- intrauterine hormone-releasing system
- bilateral tubal occlusion
- vasectomized partner (provided that the partner is the sole sexual partner of the woman of childbearing potential and has received medical assessment of the surgical success)
- sexual abstinence (only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment). Abstinence is only accepted as true abstinence when this is in line with the preferred and usual lifestyle of the subject (periodic abstinence \[e.g., calendar, ovulation, symptothermal, postovulation methods and withdrawal\] is not an acceptable method of contraception).
- Female subjects who are not of childbearing potential are exempt from contraceptive requirements. To be considered of non-childbearing potential female subjects must meet the following requirements: Must be permanently sterile (documented hysterectomy, bilateral salpingectomy, or bilateral oophorectomy at least 3 months before first dosing with the investigational medicinal product) or postmenopausal (defined as no menses for 12 months without an alternative medical cause).
- A male study subject must agree to use a double barrier method (eg, condom and spermicide) during sexual contact with a pregnant woman or a woman of childbearing potential ,and agree to not donate sperm during the study and for at least 90 days after the last dose of the IMP
- Medically healthy on the basis of medical history, physical examination, and clinical laboratory testing in the opinion of the Investigator
- Nonsmokers and nonusers of nicotine-containing products, including vaping devices for at least 6 continuous months before the first dosing with the investigational medicinal product and for the duration of the study, to be confirmed by cotinine testing at Screening and a smoking history of \< 5 pack years
- Negative alcohol testing at Screening and Day 1
- Negative cotinine and drug screen testing at Screening.
- Vital signs (after semi-recumbent for at least 5 minutes) that are within the following ranges at Screening:
- Systolic blood pressure (BP): 90 to 140 mmHg, inclusive
- Diastolic BP: 50 to 90 mmHg, inclusive
- HR: \> 45 to ≤ 100 bpm
- Weight ≤ 100 kg and body mass index ≥ 18 and ≤ 32 kg/m2 at Screening
- Normal renal function, defined as estimated creatinine clearance \> 90 mL/min at Screening; an Investigator can determine based on clinical judgment whether a lower clearance rate can be accepted based on the muscle composition of the subject
- Willing and able to understand the information on the nature, the scope, and the relevance of the clinical study, and to provide voluntary, written informed consent to participate in the study
- Able to communicate well with the Investigator and/or study site personnel and to comply with the requirements of the entire study
- Exclusion Criteria:
- Use of any prescription or over-the-counter (OTC) medications, herbal products (eg, cannabidiol, St John's Wort, milk thistle), or supplements/vitamins within 14 days or 5 half-lives (whichever is longer) before first dosing with IMP and for the duration of the study, with the exception of those approved by the Investigator and Sponsor (eg, oral contraceptives, hormone replacement therapy, acetaminophen for pain relief).
- Receipt of any investigational agent or treatment within 30 days or 5 half-lives, whichever is longer, before first dosing with IMP, or concurrent participation in another clinical study.
- Receipt of any protein- or antibody-based therapeutic agents (eg, growth hormones or monoclonal antibodies) within 3 months before first dosing with IMP.
- Note: Influenza and COVID-19 vaccines will be allowed if all doses in the regimen have been administered more than 21 days before first dosing with IMP.
- History of any major surgery within 6 months before first dosing with IMP.
- Prior diagnosis of COVID 19 within 90 days before first dosing with IMP.
- History of hepatic disease, or current clinically significant liver function test results, defined as ALT, AST, total bilirubin and fractionated bilirubin, or alkaline phosphatase \> 1.5 × upper limit of normal (ULN) at Screening.
- Note: Isolated bilirubin \> 1.5 × ULN is acceptable if bilirubin is fractionated, and direct bilirubin is \< 35%.
- History of any clinically relevant or chronic psychiatric, renal, hepatic, pancreatic, cardiovascular, neurological, hematological, or gastrointestinal abnormality (eg, inflammatory bowel disease)
- History of severe allergic/anaphylactic reaction
- History of autoimmune disease including glomerulonephritis
- Known hypersensitivity to the active substance or to any of the excipients of each IMP including lipopolysaccharide (LPS) and polyethylene glycol (PEG)
- History of any active infection within 14 days before dosing with IMP, if deemed clinically significant by the Investigator and Sponsor
- Any acute illness within 30 days before dosing with IMP
- Lower respiratory tract infection within 3 months before first dosing with IMP
- History of warfarin use or International Normalized Ratio ≥ 1.5
- History (within 2 years before the first dosing with IMP) of moderate or severe use disorder for any substance other than caffeine (based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition criteria)
- Known diagnosis or active infection with Hepatitis B, Hepatitis C, or human immunodeficiency virus (HIV)-1 or HIV-2
- Existence of any surgical or medical condition that, in the judgment of the Investigator, might interfere with the absorption, distribution, metabolism, or excretion of RLS-0071
- Presence of clinically significant ECG finding (confirmed upon repeat testing) that, in the opinion of the Investigator and/or Sponsor, may interfere with any aspect of study conduct or interpretation of results
- Concurrent conditions that could interfere with safety and/or tolerability measurements, as determined by the Investigator
- Pregnant and/or lactating
- Inability to produce sufficient amounts of induced sputum at baseline visit
- Inability to tolerate IV administration
- Poor venous access, as determined by the Investigator
- Unable or unwilling to cooperate with the study site staff for any reason
- Employees of the Sponsor or subjects who are employees or relatives of the Investigator
