What Year Did Paclitaxel Receive Fda Approval

Paclitaxel, also known by the brand name Taxol, is a chemotherapy drug used to treat various types of cancer, including ovarian, breast, lung, and Kaposi’s sarcoma. It was originally derived from the bark of the Pacific yew tree and has been shown to be effective in shrinking tumors and improving survival rates. Paclitaxel received approval from the U.S. Food and Drug Administration (FDA) in 1992 for the treatment of metastatic ovarian cancer and in 1994 for the treatment of breast cancer. Since then, it has been widely used as a first-line treatment for these and other types of cancer.

FDA Approval Timeline

Paclitaxel, a chemotherapy drug, has a rich history of FDA approvals, spanning several decades and multiple indications. Here’s a detailed timeline of its FDA approvals:

  • 1989: First FDA Approval

    The FDA granted paclitaxel accelerated approval for the treatment of advanced ovarian cancer.

  • 1994: Expanded Approval for Ovarian Cancer

    The FDA fully approved paclitaxel for first-line and recurrent ovarian cancer based on positive clinical trial results.

  • 1997: Approval for Breast Cancer

    Paclitaxel received FDA approval as a first-line treatment for metastatic breast cancer, either alone or in combination with other drugs.

  • 2004: Approval for Non-Small Cell Lung Cancer

    The FDA approved paclitaxel in combination with carboplatin for the treatment of locally advanced or metastatic non-small cell lung cancer.

  • 2005: Expanded Approval for Breast Cancer

    The FDA granted approval for paclitaxel to treat early-stage breast cancer in combination with other drugs as part of adjuvant therapy.

  • 2017: Approval for Pancreatic Cancer

    Paclitaxel received FDA approval for the treatment of metastatic pancreatic cancer in combination with gemcitabine.

Clinical Trial History of Paclitaxel

Paclitaxel is a diterpenoid alkaloid first isolated from the bark of the Pacific yew tree (Taxus brevifolia). It is a potent anti-cancer agent that has been used to treat a variety of solid tumors, including breast, lung, and ovarian cancer.

Paclitaxel was first discovered in 1971 by a team of scientists at the National Cancer Institute (NCI). The team was led by Dr. Robert Guarnaccia, who was searching for new natural products that could be used to treat cancer. Guarnaccia and his team found that paclitaxel was highly effective at inhibiting the growth of cancer cells in vitro.

In 1983, the NCI began clinical trials of paclitaxel in patients with advanced cancer. The trials showed that paclitaxel was a safe and effective treatment for a variety of cancers, including breast, lung, and ovarian cancer. Paclitaxel was approved by the FDA for the treatment of ovarian cancer in 1992 and for the treatment of breast cancer in 1994.

Timeline of Paclitaxel’s FDA Approval

  • 1983: Phase I clinical trials begin.
  • 1989: Phase II clinical trials show promising results in treating ovarian and breast cancer.
  • 1992: FDA approves paclitaxel for the treatment of ovarian cancer.
  • 1994: FDA approves paclitaxel for the treatment of breast cancer.
