Market Challenge - High Cost of Therapy and Treatment

The high cost of therapy and treatment poses a significant challenge for the growth of the medullary thyroid cancer drugs market. Targeted drug therapies such as vandetanib, cabozantinib and lenvatinib that are used for advanced MTC treatment come with a very high price tag, sometimes exceeding six figures annually for an individual. This not only impacts the affordability for patients but also proves a hurdle in reimbursement negotiations with public and private health insurers.

The socio-economic disparities also influence the access to and uptake of these expensive drugs across different regions and countries. Moreover, the long-term treatment required for MTC patients puts further financial strain on them. Addressing the issues pertaining to the high financial toxicity of drugs will be important for pharmaceutical companies to facilitate greater adoption as well as maintain a stable market position over the coming years.

Market Opportunity - Development of Novel Next-generation RET Inhibitors

The development of novel next-generation RET inhibitors presents a major growth opportunity for players in the medullary thyroid cancer drugs market. Around 60% of MTC cases are caused due to mutations in the RET proto-oncogene which results in uncontrolled cell division.

Current drugs have generally shown effectiveness in treating RET-altered MTC but their overall response rates still remain at around 30-50%. There exists scope for developing newer RET inhibitors that can achieve higher response rates as well as overcome resistance against first-line therapies.

Companies are investing in research exploring selective small molecule RET tyrosine kinase inhibitors and RET-targeted antibody drug conjugates. Some of these pipeline drugs have shown encouraging results in early clinical studies. Their successful approval and commercialization will expand treatment options as well as drive significant revenue for market participants.

Medullary thyroid cancer (MTC) treatment varies based on disease stage at diagnosis. For early-stage MTC, total thyroidectomy is the standard first-line treatment. If cancer has spread to local lymph nodes (stage III), prescribers may recommend radioactive iodine ablation drug I-131 (Azedra, Novartis) post-surgery.

For more advanced or metastatic MTC (stage IV), first-line systemic therapies typically involve targeted kinase inhibitors. Cabozantinib (Cabometyx, Exelixis), a multi-kinase inhibitor blocking RET, VEGFR2 and MET receptors, has become a preferred option based on improved progression-free survival shown in pivotal trials. Other RET inhibitors commonly used include vandetanib (Caprelsa, AstraZeneca) and selpercatinib (Retevmo, Eli Lilly).

When disease progresses on first-line options, prescribers may consider other targeted drugs like pralsetinib (Gavreto, Blueprint Medicines) or chemotherapy. For refractory MTC, clinical trials evaluating newer investigational agents like LOXO-292 (Loxo Oncology) may also be considered based on a patient's molecular profile and prognosis.

Key influences on treatment selection include a patient's symptoms, tumor marker levels, prior treatment history, comorbidities and genetic mutations detected. Minimizing treatment side effects while maximizing disease control are high prescribing priorities.

Medullary thyroid cancer can be divided into four stages - I, II, III and IV - based on tumor size and spread. For stage I/II diseases which are confined to the thyroid, surgery to remove the thyroid (thyroidectomy) is the primary treatment option. For patients with stage III disease where cancer has spread to lymph nodes in the neck, a more extensive surgery (modified neck dissection) along with thyroidectomy is recommended.

For symptomatic or progressive stage IV diseases where cancer has metastasized to other parts of the body, drug therapy is preferred. Two of the most commonly used drug regimens are vandetanib and cabozantinib. Vandetanib (Caprelsa) is a tyrosine kinase inhibitor that works by blocking some of the enzymes involved in tumor growth and spread. It is preferred for symptomatic or progressive medullary thyroid cancer after frontline therapies. Cabozantinib (Cometriq/Cabometyx) another tyrosine kinase inhibitor blocks the RET protein known to drive medullary thyroid cancer.

For palliative care, localization of metastatic lesions by imaging tests and surgical removal or thermal ablation procedures provide relief from symptoms in select cases where it is feasible. External beam radiation therapy may also help control localized bone or brain metastases.

Focus on targeted drug development: Leading players like Bristol-Myers Squibb, Exelixis and Takeda have focused their R&D efforts on developing targeted drugs to treat MTC. Bristol-Myers Squibb developed Cabometyx (cabozantinib), an oral TKI approved in 2016. It exhibited significant antitumor activity in RET mutation-positive advanced MTC patients. This helped Bristol-Myers Squibb gain a significant market share.

In-licensing/partnership deals: Companies lacking internal expertise have forged partnerships and in-licensing deals. For example, in 2015 Exelixis in-licensed cabozantinib from Bristol-Myers Squibb for certain territories. This reduced Exelixis' development costs and risks. It has since marketed cabozantinib under the brand name Cometriq and seen revenues grow.

Expansion into new indications: Successful drugs are being evaluated in new indications/settings to expand use. Cabometyx is now being studied in adjuvant and neoadjuvant MTC settings which, if successful, could capture more patients earlier in treatment. This strategy of Exelixis helped sustain Cabometyx sales even after losing exclusivity in the U.S.

These strategies of targeted drug development, partnerships and expansion into new settings have helped companies achieve regulatory approvals faster, reduced costs and risks, and maximized commercial potential of drugs like Cabometyx, leading to increased market share and revenues. They have set standards for success in this space.
