The landscape for rare pediatric diseases has long been overshadowed by the success stories of treatments for common adult conditions. However, a Florida-based radiopharmaceutical company, Advanced Innovative Partners (AIP), is venturing into uncharted territories, determined to bridge the gap for the thousands of children grappling with rare and often overlooked illnesses.

The Orphaned Battle: AIP’s Mission in Rare Pediatric Diseases

A rare or orphan disease is characterized by its low prevalence, affecting less than 6.5–10 cases in 10,000 people. The National Organization for Rare Disorders (NORD) and Orphanet are dedicated organizations working towards the betterment of individuals grappling with such rare conditions. Orphan drugs, designed for the diagnosis, prevention, or treatment of these orphan diseases, play a pivotal role in addressing the unique healthcare needs of this underserved population.

The US Food and Drug Administration (FDA) actively contributes to the field by maintaining a comprehensive list of orphan drug designations and approvals. Within this realm, partial orphan drugs emerge, showcasing dual indications—serving both orphan and non-orphan purposes.

So far, a staggering 7,000 rare pediatric diseases have been identified, yet a mere 5% boast FDA-approved pharmacotherapies. The term “orphan diseases” aptly characterizes these conditions, as the small patient populations render them commercially unattractive to pharmaceutical giants. This unfortunate reality translates into a lack of viable treatments, leaving afflicted children to contend with debilitating symptoms and truncated life expectancies.

Technologies and methods to diagnose rare diseases when ES is unrevealing. Many of these technologies complement each other, fill the missing gaps, and should be analyzed in an integrated manner. The selection between metabolomics, proteomics, methyl profiling, and immune assays should be guided by the patient’s clinical presentation and existing candidate genes identified through sequencing. Functional studies can be used to validate strong candidate variants or elucidate the underlying molecular mechanism of the disease after identifying the causative gene. ES: Exome Sequencing, GS: Genome Sequencing, UN: unstimulated. These challenges can be at the level of interpretation or detection. GS: genome sequencing, ASE: allele-specific expression, VUS: variant of unknown significance. Marwaha, S., Knowles, J.W. & Ashley, E.A.

In response to this unmet need, AIP has positioned itself as a pioneer, harnessing its expertise in radiochemistry and drug development to craft a beacon of hope for families navigating the tumultuous waters of rare pediatric diseases. Dr. Stanley “Stan” Satz, Co-Founder, Chairman & Chief Scientific Officer of AIP, underscores the promise of radiopharmaceuticals in this domain, stating, “Radiopharmaceuticals are ideally suited for rare disease applications as they can selectively deliver radiation payloads directly to organs of interest.”

Precision Beyond Measure: AIP’S Radiopharmaceutical Arsenal

AIP’s arsenal is built upon the strategic use of radioisotopes, including lutetium-177, copper-64, and gallium-68. These elements form the crux of diagnostic scans and treatments that hold the potential to revolutionize the landscape of rare pediatric diseases. By employing precision-targeted radiomedicines, AIP aims to unleash a profound impact on the lives of children grappling with these devastating conditions.

Schematic representation of the decay process. (a) Decay scheme of 177mLu to 177Lu. (b) Process of bond rupture. The metastable isomer 177mLu is coordinated to a very stable complex (left side). During the decay via internal conversion the nucleus excess of energy is transferred to an inner electron causing an auger electron cascade (center). After the cascade the atom is in a highly charge state, the chemical bonds are broken and the freed 177Lu can be separated (right side).

One of the first examples using in vivo positron emission tomography (PET) for noninvasive monitoring of copper-64 (64Cu)-radiolabeled polyethylene glycol (PEG)-modified exosomes, achieving excellent imaging quality and quantitative measurement of blood residence and tumor retention. PEGylation not only endowed exosomes with a superior pharmacokinetic profile and great accumulation in the tumor versus traditionally reported native exosomes but also reduced premature hepatic sequestration and clearance of exosomes, findings that promise enhanced therapeutic delivery efficacy and safety in future studies.

68Ga-radiolabeling of a DOTA-precursor. First, the reaction mixture is prepared by adding 68Ga eluate to a mixture consisting of a suitable buffer, precursor, and additives if necessary. Second, the reaction mixture is incubated for a specific reaction time and temperature to achieve 68Ga chelation. Third, the reaction mixture can be purified using a solid phase extraction (SPE) method. The 68Ga-radiopharmaceutical is trapped on the column while free 68Ga, 68Ge impurity, and buffer pass through the column and are discarded. Finally, the product is eluted and passed through a sterile filter as the fourth step (Meisenheimer et al. 2019). Nelson, B.J.B., Andersson, J.D., Wuest, F. & Spreckelmeyer, S. (2022).
