Porfimer sodium, sold as Photofrin, is a photosensitizer used in photodynamic therapy and radiation therapy and for palliative treatment of obstructing endobronchial non-small cell lung carcinoma and obstructing esophageal cancer.

Contents

Porfimer is a mixture of oligomers formed by ether and ester linkages of up to eight porphyrin units. [1] In practice, a red light source emitting at 630 nm is used to excite the Porfimer oligomers. [2]

Porfimer is Haematoporphyrin Derivative (HpD) (See PDT).

Approvals and indications

It was approved in Canada in 1993 for the treatment of bladder cancer. [2] It was approved in Japan in 1994 (for early stage lung cancer?). [2] It was approved by the U.S. FDA in December 1995 for esophageal cancer, and in 1998, it was approved for the treatment of early non-small cell lung cancer. [2]

In August 2003 the FDA approved its use for Barrett's esophagus. [3]

Cytoluminescent Therapy is a proposed cancer treatment as a form of Photodynamic Therapy (PDT) characterized by a photosensitiser that is supposedly eliminated from normal tissue but selectively accumulated in neoplastic and dysplastic tissue. This is followed by whole body irradiation with light of the specific wave length which activates the photosensitiser. The result is supposed to be selective damage or elimination of tumor cells while normal tissues are unharmed. However, tests as of 2003 did not show any positive clinical effects in a group of 48 patients treated in this way.

Photodynamic therapy

Photodynamic therapy (PDT), is a form of phototherapy involving light and a photosensitizing chemical substance, used in conjunction with molecular oxygen to elicit cell death (phototoxicity). PDT has proven ability to kill microbial cells, including bacteria, fungi and viruses.

Aminolevulinic acid

δ-Aminolevulinic acid, an endogenous non-proteinogenic amino acid, is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals, as well as chlorophyll in plants.

Gefitinib Drug used in fighting breast, lung, and other cancers

Gefitinib, sold under the brand name Iressa, is a medication used for certain breast, lung and other cancers. Gefitinib is an EGFR inhibitor, like erlotinib, which interrupts signaling through the epidermal growth factor receptor (EGFR) in target cells. Therefore, it is only effective in cancers with mutated and overactive EGFR. It is marketed by AstraZeneca and Teva.

Methyl aminolevulinate

Methyl aminolevulinate (MAL) is a drug used as a sensitizer in photodynamic therapy. It is a prodrug that is metabolized to protoporphyrin IX. It is marketed as Metvix.

Talaporfin

Talaporfin is a chlorin based photosensitizer used in photodynamic therapy (PDT).

Ramucirumab is a fully human monoclonal antibody (IgG1) developed for the treatment of solid tumors. This drug was developed by ImClone Systems Inc. It was isolated from a native phage display library from Dyax.

Treatment of cancer

Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy and synthetic lethality. The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient. Cancer genome sequencing helps in determining which cancer the patient exactly has for determining the best therapy for the cancer. A number of experimental cancer treatments are also under development. Under current estimates, two in five people will have cancer at some point in their lifetime.

Erdafitinib

Erdafitinib is a small molecule inhibitor of fibroblast growth factor receptor (FGFR) approved for treatment of cancer and marketed under the name Balversa. FGFRs are a subset of tyrosine kinases which are unregulated in some tumors and influence tumor cell differentiation, proliferation, angiogenesis, and cell survival. Astex Pharmaceuticals discovered the drug and licensed it to Janssen Pharmaceuticals for further development.
