Antibody-Vincristine Conjugates as Potent Anticancer Therapeutic Agents.

Antibody-drug conjugates (ADCs) are a well-established class of therapeutics primarily used in oncology to selectively deliver highly cytotoxic agents into cancer cells. While ADCs should theoretically spare healthy tissues and diminish side effects in patients, off-target toxicity is still observed, all the more serious, as the drugs are extremely potent. In the quest toward safer payloads, we used the conventional chemotherapeutic drug vincristine to develop antibody-vincristine conjugates.
