Alkaptonuria Overview
Alkaptonuria, is a rare inherited disorder caused by mutations in the HGD gene, which leads to a deficiency of the enzyme homogentisate oxidase. This enzyme normally helps break down amino acids like tyrosine and phenylalanine. Without it, homogentisic acid builds up in the body, turning urine dark when exposed to air. Symptoms typically appear in adulthood, often after the age of 30. Common signs include joint and spine pain, similar to early osteoarthritis, due to cartilage damage. Patients may also have dark spots in the eyes, bluish-black ear cartilage, and discolored nails. Skin darkening and stained sweat are seen in sun-exposed or sweat-prone areas. Heart valves, kidneys, and the prostate may also be affected due to acid deposits. Breathing difficulties can occur if the chest becomes stiff. The disorder follows an autosomal recessive inheritance, requiring two faulty HGD gene copies to develop.
Alkaptonuria Diagnosis
The diagnosis and evaluation of alkaptonuria are guided by the Alkaptonuria Severity Score Index (AKUSSI), a validated clinical tool that quantitatively measures disease severity through a multidisciplinary assessment. Key clinical indicators include pigmentation of the eyes and ears, presence of prostate and salivary stones, osteopenia, stroke, and cardiac issues such as aortic valvular disease, heart failure, and atrial fibrillation. The gold-standard diagnostic test is a 24-hour urine analysis for HGA, typically performed using gas chromatography-mass spectrometry (GC-MS), which detects elevated HGA levels ranging from 1-8 grams per day. Although darkened urine is a common symptom, it is non-specific. Molecular genetic testing can confirm mutations in the HGD gene, aiding in diagnosis and genetic counseling. Imaging techniques like CT scans or MRIs are used to evaluate joint damage, while 2D-echocardiography helps assess heart valve involvement, and CT angiograms detect coronary vessel calcification in patients with alkaptonuria.
Alkaptonuria Treatment
Treatment is personalized based on the severity of symptoms in each patient. Pain management is a critical aspect, as joint deterioration caused by homogentisic acid (HGA) buildup leads to arthritis-like symptoms. Patients often receive nonsteroidal anti-inflammatory drugs (NSAIDs) to manage joint pain, while narcotics or corticosteroids may be prescribed in severe cases. Since pain progression is gradual, treatment plans require long-term monitoring and adjustments to optimize relief while minimizing side effects. For patients experiencing mobility issues, physical and occupational therapy can play a crucial role in maintaining joint flexibility and muscle strength. Therapy can help delay mobility loss and improve overall function, reducing the risk of severe disability. Lifestyle modifications, such as adopting a low-protein diet early in life, may help lower tyrosine and phenylalanine levels, potentially reducing homogentisic acid accumulation. Regular low-impact exercises, like yoga, swimming, and pilates, are encouraged to strengthen muscles without causing additional stress on the joints. In advanced alkaptonuria, roughly half of patients need hip, knee, or shoulder replacements by age 50-60, while some also undergo spinal fusion, heart-valve surgery, or urological procedures for ochronotic and calcific complications. Nitisinone suppresses homogentisic acid by blocking 4-hydroxyphenylpyruvate dioxygenase, though it's long-term adult safety is still being evaluated; high-dose vitamin C shows inconsistent benefit, and emerging AI-designed inhibitors may deliver safer, more effective disease-modifying therapy.

Marketed Drugs
HARLIKU/NITYR (nitisinone): CYCLE Pharmaceuticals
HARLIKU/NITYR is a hydroxyphenyl-pyruvate dioxygenase inhibitor indicated for the treatment of adult and pediatric patients with hereditary tyrosinemia type 1 (HT-1) in combination with dietary restriction of tyrosine and phenylalanine. HARLIKU has become the first FDA-approved treatment for alkaptonuria, marking a significant milestone in managing this ultra-rare genetic metabolic disorder. In a pivotal three-year NIH-led study, HARLIKU demonstrated strong biochemical efficacy by reducing urinary and plasma HGA levels by over 95%, addressing the core metabolic defect in alkaptonuria. It is also approved by the European Medicines Agency (EMA) under the name NITYR for the same indication.
Following its recent FDA approval, Cycle Pharmaceuticals is set to launch HARLIKU in the US by July 2025, making it the first authorized therapy available to American patients living with this debilitating condition.
In January 2024, Cycle Pharmaceuticals and Inceptua Group had announced a partnership to make NITYR Tablets available via a Free Goods Programme for eligible patients with alkaptonuria.
ORFADIN (nitisinone): Sobi
ORFADIN is a synthetic reversible inhibitor of 4-hydroxyphenylpyruvate dioxygenase indicated for use as an adjunct to dietary restriction of tyrosine and phenylalanine in the treatment of alkaptonuria. ORFADIN, developed by Sobi, contains the active substance nitisinone and is approved in the EU for the treatment of alkaptonuria in adults. ORFADIN is available in capsules and oral suspension and requires a prescription. For adult alkaptonuria patients, the recommended dosage is 10 mg daily.
ORFADIN received approval in the EU for the treatment of alkaptonuria in September 2020, marking a significant milestone in addressing this rare metabolic disorder.
Drug Class Insights
Hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors
HPPD inhibitors, particularly nitisinone, play a key role in the treatment of alkaptonuria. Nitisinone works by inhibiting the enzyme 4-hydroxyphenylpyruvate dioxygenase, a crucial step in the tyrosine degradation pathway. This inhibition effectively reduces the production of HGA, the toxic compound that accumulates in alkaptonuria due to a deficiency in the enzyme HGD. By lowering HGA levels, nitisinone helps slow the progression of tissue damage and ochronosis associated with the disease. It is currently the first and only approved therapy for alkaptonuria marketed as HARLIKU in the United States and NITYR in the European Union is a typically used in conjunction with dietary restrictions of tyrosine and phenylalanine to enhance its therapeutic effect.
Alkaptonuria, or Black Bone Disease, is a rare genetic disorder caused by a deficiency in the enzyme homogentisate oxidase, leading to the buildup of HGA. Nitisinone, originally developed for hereditary tyrosinemia type 1 (HT-1), has shown effectiveness in reducing HGA levels in alkaptonuria patients and is used alongside dietary restrictions of tyrosine and phenylalanine. It is available under two bioequivalent brand names-ORFADIN and NITYR. While both contain the same active ingredient, NITYR offers advantages such as smaller tablet size and no need for refrigeration.
The emerging pipeline for alkaptonuria remains very scarce, with nitisinone being the approved therapy and limited ongoing innovation in late-stage clinical development. This highlights a significant unmet need and opportunity for novel therapeutic approaches.

Reimbursement may be referred to as the negotiation of a price between a manufacturer and payer that allows the manufacturer access to the market. It is provided to reduce the high costs and make the essential drugs affordable. Health technology assessment (HTA) plays an important role in reimbursement decision-making and recommending the use of a drug. These recommendations vary widely throughout the seven major markets, even for the same drug. In the US healthcare system, both Public and Private health insurance coverage are included. Also, Medicare and Medicaid are the largest government-funded programs in the US. The major healthcare programs including Medicare, Medicaid, Health Insurance Program (CHIP), and the state and federal health insurance marketplaces are overseen by the Centers for Medicare & Medicaid Services (CMS).
