Summary

K-3505 P001 (PART I) is a study of an intravenously (i.v.) administered drug called K-3505. This study which will be conducted in healthy volunteers is a double-blind, placebo-controlled, single rising dose study with a primary purpose of assessing teh safety and tolerability of single i.v doses of K-3505.

Eligibility

Sex: Both males and femalesMin Age: 18 YearssMax Age: 45 Yearss

Inclusion Criteria23

Must have given written informed consent
Be willing and able to comply with the study schedule of visits, all trial procedures and restrictions, including following study diet requirements.
Be between 18 to 45 years of age, inclusive, at the time of signing informed consent.
Have a body mass index (BMI) of 18.5 to 30.0. kg/m2, inclusive.
Be a non smoker/non-user of tobacco or other nicotine products, who has not used tobacco- or nicotine-containing products (eg, nicotine patch) for at least 1 month before administration of the initial dose of trial drug, has used no more than 5 tobacco or nicotine forms (eg less than or equal to 5 cigarettes) per week within 3 months of screening, and agrees to abstain from smoking tobacco or the use of nicotine-containing products throughout study participation (through completion of the Poststudy visit).
Be judged to be in good health by the Investigator, based on clinical evaluations including laboratory safety tests, medical history, physical examination, 12-lead ECG, and vital sign measurements performed at the Screening Visit and before administration of the initial dose of trial drug.
Dark-adapted pupil diameter (measured with pupillometer after greater than or equal to 5 minutes at approximate 5 lux) is between 5.0 mm and 8.5 mm in both eyes, and the difference in pupil diameter between the right and left eyes is less than 0.4 mm. Pupil diameter will be measured in triplicate. The middle (median) value for each eye will be used to assess eligibility.
Screening ophthalmic exam performed by an ophthalmologist or similarly licensed professional (including assessment of visual acuity, visual fields, intra-ocular pressure, and fundoscopy) identifies no clinically significant abnormalities. Note: Routine refractive errors are not exclusionary, with the exception of myopia with refractive error greater than -3D
Meet the following requirements:
a. Is a male who agrees to all of the following:
To use an appropriate method of contraception, including a condom, from the first dose of study drug until greater than or equal to 90 days after the last dose of study drug. A male participant who had a vasectomy procedure must follow the same restrictions as a non-vasectomized male. This requirement is waived for male participants with male partners.
To not donate sperm from the first dose of study drug until greater than or equal to 90 days after the last dose of study drug.
OR
b. Is a pre-menopausal female (confirmed via screening follicle stimulating hormone [FSH] test) who is of reproductive potential or surgically sterile due to hysterectomy or bilateral salpingectomy and:
agrees to not donate eggs from the first dose of study drug for greater than or equal to 30 days after the last dose of study drug AND
agrees to remain abstinent from heterosexual activitya from Screening through greater than or equal to 30 days after the last dose of study drug OR
agrees to use (or have their partner use) a birth control method that is highly effective and has low user dependency from Screening through greater than or equal to 30 days after the last dose of study drug. Acceptable methods of birth control are:
Progestogen-only implant (e.g. etonogestrel implant)
Intrauterine device (IUD)
Intrauterine hormone-releasing system (IUS)
Bilateral tubal occlusion
Vasectomized partner
a Abstinence can be used as the sole method of contraception if it is in line with the subject’s preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ethics committees. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception.

K-3505 P001 (PART I) is a study of K-3505 in healthy male and female participants. This will be the first administration of K-3505 to humans. This is a single rising dose study composed of 2 sequential panels of 8 subjects each (Panels A and B), each having Screening (up to 28 days prior to first dose of study drug), Treatment, and Follow-Up (approximately 14 days after their last dose of study medication) periods. The Treatment period will include up to 4 dosing periods per panel. All periods for both panels will involve a single administration of K-3505 or placebo except for the final dosing period for Panel B. In the final panel tested, anticipated to be Panel B, Period 4, subjects will receive the same dose of K-3505 (or placebo) on 2 consecutive days. The dose of K-3505 used in this period will be within a range that was well tolerated during the dose escalation. Dosing is double blind meaning that neither the study participants nor the unit staff will know whether a participant is receiving K-3505 or placebo in a given treatment period. Subjects will participate in either Panel A or Panel B and be randomized to a treatment sequence within that panel. This will result in subjects being assigned to K-3505 or placebo in a 3:1 ratio in each dosing period. For each panel, there will be at least 4 days between each dosing period. Planned doses of K-3505 are noted below. All doses of K-3505 and placebo will be administered by intravenous (i.v.) infusion over approximately 2 minutes. All doses of K-3505 and placebo will be admiistered by nursing staff. Panel A • Period 1: 3 micrograms K-3505 or placebo • Period 2: 10 micrograms K-3505 or placebo • Period 3: 30 micrograms K-3505 or placebo • Period 4: 90 micrograms K-3505 or placebo Panel B • Period 1: 250 micrograms K-3505 or placebo • Period 2: 750 micrograms K-3505 or placebo • Period 3: 2000 micrograms K-3505 or placebo • Period 4: Dosing of K-3505 or placebo on 2 consecutive days. The dose of K-3505 will be the same on both days and will be within the range of doses that was well tolerated in earlier periods. In all dosing periods, subjects will be admitted into the study unit on the day prior to K-3505 or placebo administration (Day -1). They will fast a minimum of 8 hours (overnight fast) prior to K-3505 or placebo administration and will remain domiciled for at least 24 hours after K-3505 or placebo administration for safety monitoring and to assess pupillary responses. In the two-day dosing period (planned for Panel B Period 4), subjects will also fast overnight from Day 1 to Day 2 and will be discharged after the completion of the Day 2 24-h assessments.
