NCT00102258 ↗	Role of Nutrition and Hormones in Boys With Disordered Growth	Completed	Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)	Phase 2	2005-01-19	This study will determine whether adding more calories to the diet helps boys with growth problems grow better while being treated with Nutropin, a growth hormone that is used to help children grow taller. The Food and Drug Administration has approved Nutropin for use in children who are very short. This study will examine whether giving nutritional supplements in addition to Nutropin can help children grow better than with Nutropin alone. Boys between 7 and 10 years of age who are very short and below average in weight, but are otherwise healthy may be eligible for this study. Candidates must qualify for Nutropin treatments to boost their growth. Boys will be recruited for the study from the Nemours Children's Clinic in Jacksonville, FL, and from the National Institutes of Health in Bethesda, MD. Participants are randomly assigned to one of two treatment groups. One group is observed for 6 months and then receives a Nutropin injection every day for 12 months. The second group drinks 8 ounces of a high-calorie beverage called Pediasure every day for 6 months and then receives Nutropin plus Pediasure every day for 12 months. In addition to treatment, participants undergo the following tests and procedures at the schedule indicated: Baseline, 3, 6, 9, 12, 15 and 18 months - Clinical examination - Height measurement - Body composition assessment: Skin-fold thickness calipers are used in four places on the body to estimate body fat - Bioelectric impedance: A small amount of electrical current is used to calculate the percentage of body fat. Baseline, 6, 12, and 18 months - Blood tests - Bone age x-ray: x-ray of the left hand to measure growth potential - DEXA (dual energy x-ray absorptiometry) scan: x-ray scan to measure body fat, muscle, and bone mineral content. The subject lies on a flat table during the scan. Baseline, 6, and 12 months - Record of dietary intake: Parents are asked to write down everything the child eats and drinks for 3 days. Using this record, a dietitian calculates the daily caloric intake. - Total energy expenditure: This test determines how much energy the child uses. For the test, the child drinks water labeled with harmless isotopes (heavy oxygen and heavy hydrogen). For the next 10 days he collects urine in plastic tubes at home. At the end of the 10 days, the parents bring the urine to the clinic for analysis to determine how fast the labeled water leaves the body. This information is used to calculate how much energy the child expends each day. Participants' weight is measured at 2 and 4 weeks, and then monthly for the remainder of the 18-month study.
NCT00134420 ↗	Growth Hormone and Chromosome 18q- and Abnormal Growth	Completed	Genentech, Inc.	Phase 3	2001-02-01	We, the investigators at the University of Texas Health Science Center at San Antonio, want to learn if height and IQ (intelligence quotient) scores are improved by growth hormone (GH) treatment in children with chromosome 18 deletions and abnormal growth. Data from a previous study showed that growth hormone improved height in all children with 18q- and growth hormone deficiency. In addition, most of the study participants on growth hormone treatment showed an increase in IQ scores.

Nutropin: Clinical Trials Update, Market Analysis, and Future Projections

Last updated: October 29, 2025

Introduction

Nutropin (somatropin) is a recombinant human growth hormone (hGH) used primarily for treating growth hormone deficiency (GHD) in children and adults. Developed by Genentech (now a subsidiary of Roche), Nutropin has established itself as a leading therapy in pediatric and adult endocrinology. This analysis provides an in-depth review of current clinical trial developments, assesses the market landscape, and projects future growth trajectories. The insights aim to inform pharmaceutical stakeholders, investors, and healthcare professionals navigating the competitive landscape of growth hormone therapeutics.

Clinical Trials Update

Ongoing and Recent Clinical Trials

Despite decades on the market, Nutropin continues to be evaluated in various experimental settings, primarily focusing on expanding its indications and improving safety profiles. Notably:

• Gene Therapy and Long-Term Effects: Several Phase I/II trials are assessing the safety and efficacy of novel gene therapy delivery mechanisms that utilize Nutropin in combination with vectors designed for sustained release. These include approaches to optimize dosing intervals while minimizing adverse effects, especially in pediatric populations. For example, ongoing trials registered under ClinicalTrials.gov (NCT04262658) are investigating gene-editing techniques that target deficiencies in GHD.

• Treatment of Adult GHD: There is renewed interest in expanding Nutropin's indications to include adults with GHD secondary to traumatic brain injury or pituitary tumors, with ongoing Phase III trials evaluating long-term safety and efficacy. These studies aim to solidify Nutropin’s positioning in adult endocrinology beyond traditional pediatric applications.
