Plain-language summary
This trial is a Phase 2, multicenter, double-blind, randomized (ratio 2:1 TransCon CNP vs. placebo), placebo-controlled trial, designed to evaluate the safety, tolerability, and efficacy of 100 μg CNP/kg of Navepegritide (TransCon CNP) administered SC once-weekly for 52 weeks in infants with genetically verified heterozygous ACH, aged 0 to \< 2 years at the time of randomization.

Inclusion Criteria:
* Written, signed informed consent by the parent(s)/caregiver(s) of the participant, and as required by the institutional review board/human research ethics committee/independent ethics committee (IRB/HREC/IEC).
* Male or female younger than 2 years of age at the time of randomization; or for open label sentinel participants, at the time of first administration of IMP.
* Clinical diagnosis of achondroplasia (ACH) with genetic confirmation of heterozygous genotype present during screening.
* Parent(s)/caregiver(s) willing to follow the protocol and instructions provided, including being able to administer weekly subcutaneous injections of trial treatment.
* Compliance to daily Vitamin D supplementation for infants aged 14 days to 1 year. All participants older than 1 year of age with serum 25-hydroxyvitamin D (25OHD) measured below lower limit of reference range at screening should start daily Vitamin D supplementation prior to randomization.
* Considered eligible based on the medical history, physical examination, and the results of vital signs, ECG, imaging, and clinical laboratory tests performed during the screening period.
Exclusion Criteria:
* Known or suspected hypersensitivity to the investigational product or related products (trehalose, tris\[hydroxymethyl\]aminomethane, succinate, and polyethylene glycol \[PEG\]).
* Genetic confirmation of ACH homozygous genotype.
* Premature birth with gestational age \< 32 weeks.
* Premature birth with gesta…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
