Study summary

The proposed study is an extension study to two ongoing double blind, randomized, placebo-controlled studies evaluating the effect of gender-specific nutritional supplementation on growth of short and lean adolescent boys and girls. The aim of the current study is to extend these short term double blind, randomized, placebo controlled studies (one in boys and one in girls) and to add an extension study, which will evaluate the long term effect of the gender specific nutritional supplementation on final height. Patients completing the ongoing studies will be offered to continue treatment with the study formula until final height. Patients reluctant to continue to consume the study formula will be offered to continue followup only during the extension study without any intervention.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participation in the former double blind, randomized, placebo controlled study to evaluate the effect of nutritional supplementation on growth of short and lean adolescent boys (protocol no. 0676-14) and girls (protocol no. 0002-15).
  • Completing at least the double blind phase of the previous studies (protocol no 0676- 14 or 0002-15)
  • Signing forme

Exclusion criteria

Exclusion Criteria:

  • Diagnosis of Growth Hormone Deficiency or treatment with Growth Hormone
  • Any known chronic disease or dysmorphic syndrome including: bone diseases, organic brain diseases, neurological disease, past or current , chronic cardiac, renal or pulmonary problems
  • Any known gastrointestinal disease including malabsorption
  • Any known organic reason for growth retardation
  • Any chronic treatment with medication that might affect appetite, weight or growth
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    Nutritional supplementation gender specific formula

    Patients at this arm will continue to consume the study formula until final height. The formula is a gender specific powder added to water containing about 25% of recommended Daily Recommended Intake (DRI) for calories, high protein (25% of calories) and multi vitamin and mineral (255-100%) of DRI for recommended daily allowance (RDA) or adequate intake

    Dietary Supplement: Gender specific nutritional standardized formula

  • Other
    Follow-up only

    Patients who are reluctant to continue to consume the study formula will come to follow-up visits only without any intervention until final height is reached

    Other: Follow-up only

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 27, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
