EU/3/18/2071 - orphan designation for treatment of medullary thyroid carcinoma
6-(2-hydroxy-2-methylpropoxy)-4-(6-(6-((6-methoxypyridin-3-yl)methyl)-3,6-diazabicyclo[3.1.1]heptan-3-yl)pyridin-3-yl)pyrazolo[1,5-a]pyridine-3-carbonitrile

Overview
On 26 October 2018, orphan designation (EU/3/18/2071) was granted by the European Commission to Loxo Oncology Limited, United Kingdom, for 6-(2-hydroxy-2-methylpropoxy)-4-(6-(6-((6-methoxypyridin-3-yl)methyl)-3,6-diazabicyclo[3.1.1]heptan-3-yl)pyridin-3-yl)pyrazolo[1,5-a]pyridine-3-carbonitrile (also known as LOXO-292) for the treatment of medullary thyroid carcinoma.
The sponsorship was transferred to Eli Lilly Nederland B.V., Netherlands, in July 2019.
Please note that this product was withdrawn from the Union Register of orphan medicinal products in December 2019 on request of the Sponsor.
Medullary thyroid carcinoma is a type of cancer affecting the thyroid, a small gland at the base of the neck that produces thyroid hormones.
The thyroid is composed of two main cell types: follicular cells, which produce hormones that help regulate growth and metabolism (the process of breaking down substances in the body), and parafollicular cells, which produce a hormone called calcitonin that helps to regulate calcium levels in the blood.
Medullary thyroid carcinoma originates from the parafollicular cells, and represents less than 5% of all thyroid cancers. Signs of cancer are difficult to detect in early stages of the disease and are often limited to a single local swelling of the thyroid which is not painful but can be felt by touching. Patients are frequently diagnosed when the disease has spread locally giving symptoms such as shortness of breath, difficulties in swallowing or changes in the voice. Some patients may have severe diarrhoea as a first sign of the disease.
Medullary thyroid carcinoma is a long-term debilitating disease which can be life-threatening if the cancer cannot be removed by surgery or spreads to other parts of the body.
At the time of designation, medullary thyroid carcinoma affected less than 0.5 in 10,000 people in the European Union (EU). This was equivalent to a total of fewer than 26,000 people*, and is below the ceiling for orphan designation, which is 5 people in 10,000. This is based on the information provided by the sponsor and the knowledge of the Committee for Orphan Medicinal Products (COMP).
* Disclaimer: For the purpose of the designation, the number of patients affected by the condition is estimated and assessed on the basis of data from the European Union (EU 28), Norway, Iceland and Liechtenstein. This represents a population of 517,400,000 (Eurostat 2018).
At the time of designation, the medicines Cometriq (cabozantinib) and Caprelsa (vandetanib) were authorised for the treatment of medullary thyroid cancer. Surgery was also used to remove the thyroid in some cases.
The sponsor has provided sufficient information to show that the medicine might be of significant benefit for patients with medullary thyroid cancer because early data show that patients in whom other treatments had failed responded to treatment with this medicine. This assumption will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.
This medicine acts by blocking the activity of a protein called RET, which normally plays a role in the development of several organs. Many patients with medullary thyroid cancer have mutations (changes) in the gene for RET. These mutations cause RET to be activated in an uncontrolled manner, which in turns makes thyroid parafollicular cells multiply out of control and become cancerous. By blocking the activity of RET, the medicine is expected to slow down the growth of the cancer.
The effects of the medicine have been evaluated in experimental models.
At the time of submission of the application for orphan designation, clinical trials with the medicine in patients with medullary thyroid cancer were ongoing.
At the time of submission, the medicine was not authorised anywhere in the EU for medullary thyroid cancer or designated as an orphan medicinal product elsewhere for this condition.
In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 13 September 2018 recommending the granting of this designation.
- the seriousness of the condition;
- the existence of alternative methods of diagnosis, prevention or treatment;
- either the rarity of the condition (affecting not more than 5 in 10,000 people in the EU) or insufficient returns on investment.
Designated orphan medicinal products are products that are still under investigation and are considered for orphan designation on the basis of potential activity. An orphan designation is not a marketing authorisation. As a consequence, demonstration of quality, safety and efficacy is necessary before a product can be granted a marketing authorisation.
