Marketed Agents or Manufacturing Processes Developed with Substantial NCI Grant Support

  1. Azidothymidine (AZT), which is also called Zidovudine, was first synthesized on an NCI grant in 1964 by Dr. Jerome Horwitz, Wayne State University, as a treatment for cancer. The compound was not successful as a cancer agent, but was examined in the 1980s as a possible treatment for AIDS. AZT, a reverse transcriptase inhibitor, was the first drug approved for the treatment of AIDS. It was patented in 1986 and developed to clinical trial by Burroughs Wellcome Co (now GlaxoSmithKline) for the treatment of AIDS . It was approved for use against HIV and AIDS on March 20, 1987 by the Food and Drug Administration (FDA).
  2. Stavudine (d4T) was first synthesized on an NCI grant in 1966 by Dr. Jerome Horwitz, Wayne State University, as a possible treatment for cancer. It was re-synthesized by Drs. Tai-Shun Lin and William Prusoff, Yale University on NCI grant CA-28852. They discovered the anti-HIV/AIDS activity of d4T and patented their discovery, which was approved on December 18, 1990. Like AZT, d4T is also a nucleoside reverse transcriptase inhibitor. Yale licensed the product to Bristol-Myers Squibb, and the New Drug Application (NDA) was approved on June 24, 1994.
  3. Fludarabine (Fludara) was synthesized by John A. Montgomery, Southern Research Institute, Birmingham, AL, on P01 CA34200. The compound was patented and licensed to Berlex Laboratories. The compound was approved for marketing by the FDA on April 18, 1991 for the treatment of B-cell chronic lymphocytic leukemia (CLL).
  4. Clofarabine (Clofar) was co-invented by John (Jack) A. Secrist, Southern Research Institute, on P01 CA34200. This compound was approved by the FDA on December 28, 2004 for the treatment of pediatric acute lymphoblastic leukema (ALL). It is currently manufactured by Genzyme.
  5. Dr. Robert A. Holton, Florida State University, invented a practical semi-synthetic synthesis of Taxol with NCI grant support that made multi-institutional clinical trials possible. He patented the process in 1989 and licensed it to Bristol-Myers Squibb in 1990. Taxol (Paclitaxel) was approved for the treatment of ovarian cancer by the FDA in 1992.
  6. For marketed agents from the National Cooperative Drug Discovery Group Program, refer to the NCDDG section of this website.

R44 CA79228 Leonard Katz, Principal Investigator
Kosan Biosciences, Inc.
Heterologous Production of Epothilone

Epothilone D, a complex polyketide that inhibits the depolymerization of microtubles, is currently in Phase I clinical trial. Katz and coworkers identified, cloned and sequenced the genes responsible for the synthesis of Epothilone D. Using vectors and methods developed at Kosan, they inserted the gene cluster from S. cellulosum into the chromosome of Myxococcus xanthus, a related, but faster growing bacterium. Next, they developed fermentation and product recovery protocols for the production and high-level purification of sufficient product to support clinical trials at a reasonable cost. This work represents the first example of heterologous production of a small molecule to reach the clinic. It also represents the largest segment of DNA (956KB) that has been used successfully for heterologous expression.

RO1 CA78577 Jessie Au, Principal Investigator
Ohio State University

Dr. Au has found that acidic and basic fibroblast growth factors induce resistance to multiple anticancer drugs with different mechanisms of action. Based on these results, a clinical trial has been initiated which includes suramin, an inhibitor of multiple growth factors, as a way to sensitize tumors to chemotherapy.

Allosteric, chiral selective drug binding to DNA

A research team has achieved an advance in the search for compounds capable of recognizing and modifying DNA on the basis of its shape rather than its sequence. The team demonstrated that WP900, an enantiomer of daunorubicin, binds to left-handed (2-DNA) form of a synthetic DNA polynucleotide. When used in conjunction with daunorubicin, which binds to a right-handed DNA (B-DNA), the DNA polynucleotide can be converted back and forth between its left-and right-handed forms.
