Tirapazamine

Tirapazamine (SR-4233) is an experimental anticancer drug that is activated to a toxic radical only at very low levels of oxygen (hypoxia). Such levels are common in human solid tumors, a phenomenon known as tumor hypoxia. Thus, tirapazamine is activated to its toxic form preferentially in the hypoxic areas of solid tumors. Cells in these regions are resistant to killing by radiotherapy and most anticancer drugs. Thus the combination of tirapazamine with conventional anticancer treatments is particularly effective. As of 2006, tirapazamine is undergoing phase III testing in patients with head and neck cancer, and similar trials are being undertaken for other solid tumor types. more...

Research and Markets: Market Leaders in Oncology 2004 - Roche and Genentech Continue to Blaze a Trail
From Business Wire, 1/24/05

DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c12125) has announced the addition of Market Leaders in Oncology 2004 - Roche and Genentech Continue to Blaze a Trail to their offering.

Roche continues to lead the oncology sector, recording oncology sales of $5,719m in 2003. This sector dominance is predicted to continue between 2004 and 2010, due to Roche's ability to combine strong sales and marketing with an innovative R&D policy.

Scope

--The oncology franchises of Bristol-Myers Squibb (BMS), AstraZeneca, Pfizer, Sanofi-Aventis and the Roche-Genentech partnership are examined

--Forecasts of future sales growth along with identification of potential blockbuster drugs and future market leaders

--Examination of the current oncology market and future directions in the search for innovative and profitable oncology products

Highlights

--The global oncology market continues to be dominated by Roche, whose growth was driven primarily by healthy sales of MabThera/Rituxan (rituximab), which saw sales rise 20.9% in 2003 to $2,063m. It is predicted that Roche will continue to dominate the oncology sector over the forecast period of 2003-10.

--BMS is experiencing problems. Its main oncology product, Erbitux (cetuximab), while expected to show healthy growth from 2003-10, is the only major product in its marketed portfolio. Revenue growth from 2003-10 is expected to come mainly from its subsidiary Oncology Therapeutic Network (OTN).

--AstraZenecas oncology portfolio has taken a serious hit due to negative outcome of the ISEL trial (Iressa Survival Evaluation in Lung Cancer). The results, released on December 17, 2004, indicate that Iressa (gefitinib) does not significantly prolong survival in patients with non-small cell lung cancer (NSCLC).

Reasons to Purchase

--Understand the current oncology market and who the market leaders are

--Identify where future growth for the sector is predicted to come from, and who the market leaders are predicted to be by 2010

--Identify and understand trends within the oncology sector to facilitate strategic development
