Harnessing Existing Drugs to Transform Pancreatic Cancer Treatment
Overview of Drug Repurposing
Drug repurposing involves using FDA-approved drugs originally developed for other diseases to treat pancreatic cancer. This strategy taps into the existing safety and pharmacokinetic data of these medications, speeding up the process of drug availability for patients. Drugs such as itraconazole, metformin, and chloroquine have shown promising anticancer effects in laboratory and clinical studies.
Benefits of Repurposing in Pancreatic Cancer
Repurposed drugs offer several advantages for pancreatic cancer treatment. They help overcome the scarcity of effective therapies, reduce development time and costs compared to new drugs, and provide a broader arsenal against this aggressive disease. Many repurposed agents target cancer stem cells, tumor microenvironment, or specific signaling pathways. Treatments like itraconazole exhibit anti-angiogenic and Hedgehog pathway inhibition, while metformin impacts cancer cell metabolism.

3. Targeting Cancer Stem Cells with Aspirin, Ivermectin, and Nanoparticle Delivery
What role do cancer stem cells (CSCs) play in pancreatic cancer progression and resistance?
Cancer stem cells (CSCs) are a subpopulation within pancreatic tumors that drive tumor progression, metastasis, and recurrence. They contribute significantly to drug resistance by evading conventional therapies through mechanisms like enhanced DNA repair, drug efflux, and apoptosis inhibition. CSCs express markers such as CD44 and EpCAM and are regulated by pathways like Wnt/β-catenin and Notch, which are critical for maintaining their stemness and survival. For more detailed insights, refer to Cancer stem cells (CSCs) and cancer progression.
How can repurposed drugs like aspirin and ivermectin target CSCs?
Repurposed non-cancer drugs have shown promise in targeting CSCs. Aspirin, known for its anti-inflammatory effects, interferes with signaling pathways pivotal to CSC maintenance and chemoresistance. Ivermectin disrupts CSC function and signaling, promoting apoptosis and reducing stemness characteristics. These drugs offer established safety profiles and ease of clinical translation. See Drug repurposing as a strategy against CSCs for more information.
How do combination therapies help overcome drug resistance in pancreatic cancer?
Combining repurposed drugs with standard chemotherapy or micronutrients enhances anti-CSC activity and can reduce treatment side effects. For example, aspirin or ivermectin paired with chemotherapy may prevent CSC-mediated relapse by targeting multiple resistance mechanisms simultaneously, improving therapeutic efficacy. More details are available in Preclinical and clinical studies on repurposed drugs for pancreatic cancer.
What advantages do nanoparticle-based delivery systems provide?
Nanoparticle delivery enhances the targeting specificity and bioavailability of CSC-directed therapies. It allows for controlled release, reduced systemic toxicity, and improved accumulation at tumor sites. This technology can boost the effectiveness of repurposed drugs against CSCs within the complex pancreatic tumor microenvironment. For further reading, see Nanoparticle-based delivery systems for CSC therapies.
Together, these strategies form a promising approach to tackle pancreatic cancer's resilience by focusing on the critical CSC population, potentially improving patient outcomes significantly.
4. Antipsychotic Drugs: A Surprising Arsenal Against Pancreatic Cancer

Insights into Pancreatic Cancer Metastasis
What is the surprising driver for pancreatic cancer metastasis?
Recent research published in Science Advances has revealed that Neuropeptide Y (NPY), traditionally recognized for its role in regulating metabolism, appetite, and satiety, is a surprising and significant driver of pancreatic cancer metastasis. Rather than merely being involved in metabolic processes, NPY facilitates the spread of pancreatic cancer cells to distant organs.
This discovery highlights NPY as an unexpected but crucial factor in pancreatic cancer progression. Pancreatic cancer’s high mortality rate is largely due to its capacity to metastasize early and extensively, making this finding particularly relevant for developing new therapeutic strategies.
Role of Neuropeptide Y (NPY) in metastasis
NPY acts beyond its normal physiological roles by promoting metastatic behaviors in pancreatic tumor cells. It influences cellular pathways that enhance the cancer cells' ability to migrate, invade, and establish secondary tumors, thus contributing to treatment resistance and poor prognosis.
Implications for targeting metastatic pathways
Targeting NPY and its signaling pathways opens a novel avenue for therapies aimed at impeding metastatic spread. By inhibiting this molecule, it may be possible to prevent or reduce metastasis, improving survival outcomes. This approach adds a fresh perspective to pancreatic cancer treatment, traditionally challenged by early metastasis and limited effective options.
