Plain English summary of protocol

Background and study aims
The Sponsor is developing the test medicine, iptacopan (also known as LNP023), to treat diseases in which the immune system damages parts of the body. Examples of diseases that iptacopan (the test medicine) may be used to treat include paroxysmal nocturnal hemoglobinuria (PNH), immunoglobulin A nephropathy (IgAN), and C3 glomerulopathy.
This study in healthy volunteers aims to answer this question: how do blood levels of the test medicine compare when it’s given in different formulations (recipes)?
This study will also provide more information on the safety and tolerability of the test medicine and any side effects.

Who can participate?
Healthy male and female participants who are unable to have a baby, aged 18 to 55 years

What does the study involve?
Participants will take part in seven study periods. In six of those study periods they will take a single oral dose of new formulations (recipes) of the test medicine, as tablets, and in one period they will take a single oral dose of the existing formulation of the test medicine, as capsules. In three of the study periods, the dose of test medicine may be taken with food. They’ll stay in the clinic for 5 nights in each study period, and there will be a minimum of 7 days between each dose of test medicine. Volunteers will have a follow-up phone call about 30 days after their final dose of test medicine and will take up to 12 months to finish the study.

What are the possible risks and benefits of participating?
1. As this is a Phase I study, the most relevant population is healthy volunteers. It is considered that the risk/benefit evaluation in this study supports the use of healthy volunteers. Women of childbearing potential are excluded from this study.
2. There is always a risk that the stipend in healthy volunteer studies could represent coercion. The time spent in the clinic, travel, inconvenience and other expenses factor in calculating the stipend. Perception of risk is not considered in this calculation.
3. When investigating new medicines there is always a risk of unexpected side effects and occasionally allergic reactions. Volunteers will be closely monitored during the study.
4. Volunteers may experience side effects from the test medicine in this study. Full information on possible side effects is provided to volunteers in the Participant Information Sheet and Informed Consent Forms.
5. There may be an extended period of fasting for the volunteers taking part in this study. To ensure an adequate fluid intake, the volunteers will be placed under a strict fluid intake regime, with no fluids to be consumed 1 hour pre/post dosing, after which water can be consumed freely. Volunteers will be monitored for signs of dehydration and fatigue.
6. Blood samples will be collected during the study. Collection of these samples can cause soreness and bruising of the arms but these problems usually clear up within a few days to a few weeks.
7. ECG stickers on volunteers' chests and limbs may cause some local irritation and may be uncomfortable to remove but volunteers will be closely monitored to ensure any local irritation does not persist.

10. History or evidence of testicular disease (males).
11. Sexually active males unwilling to adhere to the contraception requirements of the study as detailed below:
11.1. A condom is required for all sexually active male participants to prevent them from fathering a child and to prevent delivery of the investigational drug via seminal fluid to their partner.
11.2. Males with partners of childbearing potential must use a condom during intercourse while taking investigational drug and for 95 days after stopping investigational drug (duration to cover one spermatogenesis cycle plus 5 half-lives) as a precautionary measure.
11.3. In addition to condoms, as a precaution, if a male has a female partner of childbearing potential, the partner must use a method of effective contraception from the list below whilst the male participant is taking the investigational drug for 95 days after he stops taking the investigational drug (duration to cover one spermatogenesis cycle plus 5 half-lives):
11.3.1. Partner’s bilateral tubal occlusion.

If needed, paracetamol/acetaminophen up to 4 g per 24 hours is acceptable, but must be documented in the Concomitant medications / Significant non-drug therapies page of the case report form (CRF). Exceptions may apply, as determined by the Investigator, if each of the following criteria are met: medication with a short half-life if the washout is such that no pharmacodynamic activity is expected by the time of dosing with IMP; and if the use of medication does not jeopardize the safety of the trial participant; and if the use of medication is not considered to interfere with the objectives of the study.
19. Donation of blood or plasma or loss of greater than 400 ml of blood within the previous 3 months.
20. Hemoglobin below the lower limit of the reference range at screening or first baseline (admission).

24. Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs, or which may jeopardize the participant in case of participation in the study, e.g., significant cardiovascular, chronic respiratory, neurological or psychiatric disorder. The Investigator should make this determination in consideration of the participant’s medical history and/or clinical or laboratory evidence of any of the following:
24.1. Inflammatory bowel disease, peptic ulcers, GI disease including rectal bleeding.
24.2. Major GI tract surgery such as gastrectomy, gastroenterostomy, or bowel resection.
