by The cancer drug pipeline is rapidly expanding with many new and promising therapies in development aimed at improving patient outcomes. Although cancer treatment has advanced significantly in recent years, there remains a significant unmet need that drug developers are striving to address through their pipelines. This article analyzes the current state of the oncology drug pipeline, highlighting some of the most notable programs that could transform cancer care if approved.
Introduction
Cancer remains one of the leading causes of death worldwide, responsible for nearly 10 million deaths in 2020 according to the World Health Organization. While treatment options have improved, many cancers still have poor survival rates and face difficulties such as drug resistance, side effects from chemotherapy, and lack of effective options for those with advanced disease. This underscores the critical need for continued research and development of new therapies. The good news is that the cancer drug pipeline is more robust than ever, with over 1,300 drugs and biologics currently in clinical trials globally according to a report from Evaluate Pharma. These therapies adopt various novel approaches with the goal of enhancing survival and quality of life for cancer patients.
Pipeline by Cancer Type
Most of the active programs in development are focused on more prevalent cancer types where the commercial potential is greater due to the larger patient populations. One report found that the most heavily targeted cancers in the pipeline include breast cancer (157 programs), lung cancer (141 programs), hematologic cancers like leukemia (122 programs), and colorectal cancer (114 programs). However, there are also a decent number of programs for rarer cancers that have traditionally lacked effective treatments like brain cancer, pancreatic cancer, ovarian cancer and others. Some of the more promising programs targeting specific cancer types are highlighted below.
Breast Cancer
There are several interesting programs enhancing HER2-targeted treatment and immunotherapy approaches for HER2-positive and triple-negative breast cancer, respectively. For HER2-positive disease, agents like fam-trastuzumab deruxtecan-nxki (ENHERTU) which delivers chemotherapy directly to HER2-expressing cells have shown strong efficacy. For triple-negative breast cancer lacking effective endocrine or HER2-based therapies, novel immune checkpoint inhibitors in combination with other agents hold promise.
Lung Cancer
The high unmet need in lung cancer has driven significant innovation, including therapies that target specific mutations driving subsets of non-small cell lung cancer as well as new immunotherapies and combinations. Potential blockbusters include sotorasib (Lumakras) for KRAS G12C mutant lung cancer and margetuximab for HER2-mutant disease. Immuno-oncology combos are also being advanced.
Blood Cancers
The blood cancer pipeline looks to broaden options beyond traditional chemotherapy backbones. CAR-T cell therapies targeting B-cell malignancies have made great strides and new targets are being explored. Novel mechanisms for acute myeloid leukemia aim to improve upon standard chemotherapy. Longer-term remissions are the goal.
Colorectal Cancer
While Oncology Drug Pipeline Analysis have not delivered for colorectal cancer as in other solid tumors yet, targeted agents blocking specific pathways remain an active area. Agents in development include combinations blocking both VEGF and EGFR pathways which have shown promise based on early data.
Pipeline by Mechanism of Action
Beyond focusing on specific cancer types, the pipeline encompasses a diversity of novel approaches and mechanisms of action (MOAs). Some of the most promising areas include:
Immunotherapies
While checkpoint inhibitors have revolutionized some cancers, many challenges remain to expand their use. Newer agents and combination strategies aim to improve response rates and durability. Most activity is seen with combinations that may become standard-of-care.
Cell Therapies
Chimeric antigen receptor (CAR) T-cell therapies are leading the charge, but new targets and additional cell types are under exploration beyond CD19 for hematologic cancers. ‘Solid tumor’ CAR-Ts face many hurdles, but progress continues.
Targeted Protein Therapies
Beyond tyrosine kinase and other enzyme inhibitors, novel protein degraders that induce destruction of oncoproteins like BCL-2 or MDM2 enter the clinic. Their potential is huge if safety profiles are established.
Antibody-Drug Conjugates
The promise of selectively delivering cytotoxic payloads directly to cancer cells via antibodies continues to be realized, with new ADC technologies and targets broadening the scope of these agents.
Novel Pathway Inhibitors
New strategies aim to block cancer drivers beyond established targets, whether mutations, fusions or amplified genes fueling tumor growth and survival.
In summary, the oncology pipeline assessed has never looked more promising. With such a diversity of novel mechanisms and combination strategies being advanced, many experts believe we are on the cusp of transformative advances that could make good on the promise of more effective and curative cancer therapies. Of course, challenges to drug development remain, but if even a fraction of the most promising programs translate to approved therapies, it could vastly change outcomes for many cancer patients. The coming years should provide answers on which of these approaches deliver and help conquer cancer.
