Abstract:
Low productivity and the escalating costs of drug development have been well documented over the past years. A fraction of new pre-clinical compounds successfully pass experimental test batteries, and less than 10% of these compounds that enter clinical trials ultimately make it to the market. These challenges in the "critical path" of drug development will be discussed for drugs in the field of oncology, regarding the i) the impact of FDA and EMEA guidelines, and ii) microdosing studies/phase 0 trials before a drug enters phase I to III, to inform drug development, compressing drug development timelines and decision-making for continuation into clinical trials. Moreover, this review should embark on i) how to find new key molecules involved in life-and-death decision of a cell, how ii) old drugs will have a revival for new indications, because of novel information for their mode of action, and iii) how the revolutionary advances - high-throughput technologies, gene therapy and the deciphering of the human genome - do have their potential to develop personalized therapy. Therapy has progressed from an age of administering herbal remedies and organ extracts to an era of meticulously planned drug discovery, when pharmaceutical industry was born in a Western understanding. The relevant patents are discussed.
Insights
Drug development faces challenges in oncology, but microdosing studies and advanced technologies like gene therapy can accelerate timelines and personalize treatments. This review explores strategies to improve the drug discovery critical path.
Area of Science:
- Oncology Drug Development
- Pharmacology
- Biotechnology
Background:
- Drug development is costly and inefficient, with low success rates from pre-clinical stages to market approval.
- The oncology drug development pipeline faces significant hurdles, impacting the timely delivery of new cancer therapies.
- Current drug discovery processes are lengthy and expensive, necessitating innovative approaches to improve efficiency.
Purpose of the Study:
- To discuss challenges in the oncology drug development critical path.
- To explore the impact of regulatory guidelines (FDA, EMEA) and microdosing studies (Phase 0 trials) on drug development.
- To review novel strategies for identifying therapeutic targets, repurposing existing drugs, and leveraging advanced technologies for personalized oncology therapy.
Main Methods:
- Review of regulatory guidelines from the FDA and EMEA.
- Analysis of microdosing studies (Phase 0 trials) for early drug development decision-making.
- Exploration of high-throughput technologies, gene therapy, and genomics for personalized medicine.
Main Results:
- Microdosing studies can inform drug development and compress timelines, aiding decisions on advancing compounds to clinical trials.
- Identifying novel molecules involved in cell death pathways and repurposing old drugs for new indications can revitalize therapeutic options.
- Revolutionary advances in high-throughput screening, gene therapy, and genomics offer potential for developing personalized cancer treatments.
Conclusions:
- Optimizing the drug development critical path in oncology requires strategic use of regulatory insights and early-phase studies.
- Novel approaches, including target identification, drug repurposing, and advanced biotechnologies, are crucial for advancing personalized oncology therapies.
- The evolution of drug discovery from traditional methods to precision medicine, informed by genomics and innovative technologies, is reshaping cancer treatment.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
