MedKoo Cat#: 202865 | Name: Temoporfin

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Temoporfin, also known as m-THPC or KW-2345, is a synthetic light-activated chlorin with photodynamic activity. Upon systemic administration, temoporfin distributes throughout the body and is taken up by tumor cells. Upon stimulation of temoporfin by non-thermal laser light (at 652 nm), and in the presence of oxygen, this agent produces highly reactive short-lived singlet oxygen and other reactive oxygen radicals, resulting in local damage to tumor cells. This may kill tumor cells and may reduce the tumor size.

More Info
Temoporfin (INN) is a photosensitizer used in chemotherapy for the treatment of squamous cell carcinoma of the head and neck. In October 2001, Foscan® was approved in the European Union, Norway & Iceland as a local therapy for the palliative treatment of patients with advanced head and neck cancer who have failed prior therapies and are unsuitable for radiotherapy, surgery or systemic chemotherapy.   Foscan injection contains the active ingredient temoporfin, which is a type of medicine called a photosensitising agent. It is used in photodynamic therapy (PDT) of advanced head and neck cancer. The medicine is administered by injection into a vein and is given 90 hours to distribute around the body, including into the cancer cells. The medicine doesnÂ’t do anything until it is activated by a particular type of light. After 90 hours, a specialist in photodynamic therapy will direct a laser light source very precisely at the cancer. This light activates the medicine that is in the cancer cells, causing it to destroy them. The aim of the treatment is reduce symptoms by shrinking the cancer. This is called palliative treatment. It will not cure the cancer. Normally only one treatment is given, but this may be repeated after a few weeks.   Temoporfin (INN) is marketed in the European Union under the brand name Foscan. The US FDA deemed Foscan non-approvable in 2000. The EU approved its use in June 2001. It is photoactivated at 652 nm ie by red light. Patients can remain photosensitive for several weeks after treatment. [source: http://en.wikipedia.org/wiki/Temoporfin].   Current developer:    Biolitec Pharma Ltd.
