Objective: The objective of this study is to assess the postmarketing status: Efficacy and safety drugs and biologics related with cancer approved under expedited review. Methods: This observational, analytical study was carried between January and April 2016 by the Department of Pharmacology and Medical Oncology, Saveetha Medical College. Drugs approved under expedited review, fast-track status and its association with anti-cancer effects, postmarketing efficacy and safety, propensity to induce the second tumor was noted. Drug approval status and average time of review process were obtained from the United States-Food and Drug Administration (FDA), Center for Drugs and Biologics Center (Center for Drug Evaluation and Research and Center for Biologics Evaluation and Research). Postmarketing adverse events and safety issues were collected FDA adverse effects reporting system. Further, evidence efficacy and safety of drugs were taken from various meta-analysis, reports on BioMed journals, and Cochrane systematic reviews. Results: In the last 5 years, 166 products were approved by expedited review. Out of 166, 48 (28.9%) drugs/biologics are anticancer drugs and drugs used in precancerous conditions. The average time of review varies from19 months to 8.2 months. Out of these 48 molecules, 37 (77%) molecules received serious adverse event alert. Positive correlation is seen between average time of review and number of adverse events reported. Seven (14.5%) drugs were proven to induce second tumor among receivers. Conclusion: Although expedited review facilitates faster approval of drugs; selection and assessment criteria should be stringent to prevent clinical failure, serious adverse effects of such drugs exposed to many individuals. Focus should be given developing chemosensitizing molecule and evaluation of metronomic regimen which is being more optimistic in current cancer therapeutics.
