This differentiated approach fulfilling unmet needs will have strong implications on market growth in coming times.

Market Challenge - High reatment costs

One of the major challenges faced by the Acute Intermittent Porphyria market is the high treatment costs associated with managing the condition. AIP requires costly lifelong management to prevent attacks and potential complications. The primary treatments for AIP attacks include intravenous hemin injections which can cost thousands of dollars per injection.

In addition, long term care and monitoring is needed through frequent lab testing, specialist visits, diagnostic tests and drugs to help manage symptoms. All of these contribute to a heavy economic burden on patients and the overall healthcare system. The rarity of the condition means there are relatively few patients to help offset the high fixed research and development costs of new therapies.

Drug manufacturers are hesitant to invest in developing more affordable treatment options due to the small potential market size. Unless awareness and appropriate diagnosis improves significantly, high costs will continue restricting patient access to care and impacting the growth of the AIP market.

Market Opportunity - Expansion into Emerging Markets

One of the key opportunities for the Acute Intermittent Porphyria market is expansion into emerging markets. Currently, the market is dominated by developed countries in North America and Western Europe where awareness is higher and diagnostic capabilities are more advanced.

However, AIP has a global prevalence and remains underdiagnosed in many developing regions. There is immense potential to grow the market and improve patient outcomes by increasing diagnosis rates and access to existing therapies in emerging markets like Latin America, Asia Pacific and Middle Eastern countries. These countries represent rapidly growing healthcare sectors with rising income levels making treatment more affordable over time.

Companies operating in the AIP market could look at partnerships with local providers, patient advocacy groups and governments to launch awareness campaigns, education programs for physicians and subsidised treatment access models.

By expanding into new patient populations in emerging markets, companies can achieve significant revenue growth and economies of scale to help drive long term profitability and investments in developing next generation therapies.

Acute Intermittent Porphyria (AIP) typically presents in three stages requiring different lines of treatment. The initial stage consists of less severe attacks and symptoms which can often be managed at home with diet modifications and carbohydrate supplementation. Prescribers may recommend glucose polymer products like Polycal to help prevent further buildup of toxic metabolites.

As attacks worsen in the second stage, patients require hospitalization for intravenous hemin administration. Hemin (Panhematin) acts as the primary treatment as it helps reduce ALA and PBG levels. It is administered every 12-24 hours until symptoms improve which can take 3-5 days. Aggressive carbohydrate intake continues alongside hemin.

For severe, life-threatening attacks, the third stage involves intensive care support measures. In addition to hemin therapy, opioids may be needed to manage severe abdominal pain. Medications like Tramedo or Dilaudid are prescribed via intravenous drip. Close monitoring is essential at this stage to watch for complications affecting kidneys, liver or blood.

The extent of attack, dosage and duration of treatment varies case by case based on severity and individual response. Cost implications also influence product choices with cheaper oral alternatives gaining traction. Hemin remains the mainstay but options like Normosang may see increased uptake if proven cost-effective. Patient education too impacts compliance and outcomes.

Acute Intermittent Porphyria (AIP) has four main stages - remission, pre-crisis, acute attack, and convalescence. The preferred treatment depends on the stage.

During remission and pre-crisis, prevention is key. Patients aim to avoid known triggers like certain medications.

If an acute attack occurs, hospitalization is usually required for intravenous hemin administration. Hemin, a branded product containing Panhematin, blocks the overproduction of porphyrins. It remains the first-line treatment for attacks as it significantly reduces attack duration from weeks to days and risk of permanent neurological damage.

For patients with frequent attacks, lifelong preventative treatment may be needed. Second-line oral options include beta-blockers, which are thought to decrease hepatic ALA synthase activity. Commonly used branded drugs are Inderal and Tenormin.

During convalescence, care focuses on rest, tackling any nutritional deficiencies, and psychological support. Recovery can take weeks.

The stage and severity of symptoms usually determine the best treatment approach. Hemin is highly effective during active attacks when symptoms require urgent management. Oral preventative medications may provide sustained relief for frequent sufferers. This tailored approach aims to minimize attacks, their impact, and long-term complications of this rare but serious disease.

Focus on clinical development for new treatments - One of the main strategies adopted by companies has been investing aggressively in clinical research and development for new drugs to treat Acute Intermittent Porphyria (AIP). For example, Recordati Rare Diseases invested over $100 million between 2014-2018 in clinical trials for its oral drug rigosertib for AIP. The Phase 3 INSPIRE trial completed in 2018 showed promising results, reducing AIP attacks. If approved, rigosertib could become the first new treatment in over 20 years for AIP.

Partnerships and collaborations for drug development - Given the small patient population and commercial viability challenges for orphan drugs, partnerships have been important for companies to maximize resources and share risks/rewards. In 2019, Alnylam Pharmaceuticals collaborated with Dicerna Pharmaceuticals to develop an RNAi therapeutic (DCR-AIP) for AIP. By combining their expertise and platforms, they hope to accelerate development of new treatment options.

Acquisitions of promising pipeline assets - Acquisitions have enabled companies to gain access to mid-late stage clinical assets and expand their portfolios in this market. In 2020, Recordati acquired Orphan Europe, gaining the marketing rights to cysteamine bitartrate, a drug approved in Europe for AIP. This addition boosted Recordati's presence and commercialization capabilities for AIP treatments.
