Open the CIPO recordAbstract From the Canadian patent
We have surprisingly discovered that the administration of a G1 and/or S phase drug such as .beta.-lapachone in combination with a G2/M drug such as a taxame derivative such as paclitaxel resulted in an unexpected greater than additive (i.e. synergistic) reduction in the number of tumors (and tumor volume) as compared with the administration of these agents alone. In addition no signs , of toxicity or weight loss were observed. The present invention relates to a method for treating a mammalian tumor using combinations such as a taxane derivative, preferably paclitaxel, and a .beta.-lapachone or a derivative or , analog thereof.

Why it's free to use
- Filed April 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
