SkyePharma has licensed exclusive marketing and distribution rights for DepoCyte, a treatment for lymphomatous meningitis, to Mundipharma for most European and Eastern European countries.

Under the terms of the agreement, Mundipharma will pay SkyePharma €4.25m (US$4.9m) on signature plus additional milestone payments that may amount in total to €10.75m (US$12.3m). SkyePharma will manufacture the drug at its San Diego facility and supply to Mundipharma associates at an agreed transfer price. Mundipharma will also pay SkyePharma an additional royalty on sales.

SkyePharma's ceo, Michael Ashton, said: 'We are delighted to have found in Mundipharma a partner which can bring the focused marketing and sales support needed for a specialist product like DepoCyte. Mundipharma shares our view that lymphomatous meningitis is both under-diagnosed and under-treated and that DepoCyte offers great potential to bring relief of suffering from this devastating complication of cancer. We look forward to working together.'

What is Lymphomatous meningitis?

Lymphomatous meningitis is a comparatively uncommon condition with approximately 10,000 cases reported worldwide each year. Consequently DepoCyte has been granted Orphan Drug status in the USA. SkyePharma is currently conducting a Phase IV study, the data from which will be submitted in applications to the FDA and EMEA to expand the treatment indication for DepoCyt/DepoCyte to neoplastic meningitis associated with solid tumours. This is a more common condition and would increase the number of patients eligible for treatment with DepoCyt/DepoCyte approximately threefold.

What is Depocyte?

DepoCyte (depocyt in the US) is a sustained release injectable formulation of cytarabine and is approved in both the USA and Europe for the treatment of lymphomatous meningitis, a serious late-stage complication of lymphoma, a form of cancer affecting the lymphatic system. Lymphomatous meningitis is a subset of neoplastic meningitis. Cytarabine is known to be an effective treatment for neoplastic meningitis but is rapidly metabolised and so patients require spinal (intrathecal) injections every two days. SkyePharma's proprietary DepoFoam delivery technology encapsulates cytarabine in water solution within minute particles of lipid. After injection, these particles gradually degrade, prolonging the release of the drug and extending the period between injections to two weeks. This brings quality of life benefits to the patient and also savings in hospital costs. Furthermore, maintenance of sustained higher levels of cytarabine in the cerebrospinal fluid may also prolong the time to neurological progression.

About neoplastic meningitis

In many forms of cancer, secondary tumours (metastases) form in the meninges, the membrane that surrounds the brain and spinal cord. From autopsy data, neoplastic meningitis affects up to 20% of all cancer patients (Posner, Neurological Complications of Cancer, 1995) but the condition is only diagnosed in 4-7% of cancer patients. The symptoms are pain and progressive neurological deterioration and few patients survive more than a few months, either from neurological dysfunction or from the primary tumour. The goal of therapy for neoplastic meningitis is palliation, not cure. The principal treatments are normally radiotherapy and chemotherapy to clear the cerebrospinal fluid of malignant cells and to prevent or slow recurrence. Most cytotoxic drugs do not cross the blood-brain barrier so the main chemotherapy treatments are methotrexate or cytarabine, injected intrathecally. These drugs reduce pain and slow neurological degradation but have the disadvantage of rapid clearance from the circulation and so require frequent injections.
