What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new combination treatment for people with metastatic pancreatic cancer. The study explores whether adding proglumide, taken orally three times a day, to standard chemotherapy drugs gemcitabine and nab-paclitaxel can improve treatment outcomes. Participants must have metastatic pancreatic cancer that has not been treated with these specific chemotherapy drugs before. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot be on any concurrent chemotherapy, biologic, or hormonal therapy for cancer treatment while participating in this trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

In earlier studies, patients tolerated the combination of gemcitabine and nab-paclitaxel well. Research shows that these drugs, often used together to treat pancreatic cancer, usually cause mild to moderate side effects.

For proglumide, early results suggest it is safe when used with gemcitabine and nab-paclitaxel. One study determined the best dose of proglumide and found its side effects manageable. While some side effects might occur, they are not severe and can be treated with medical care.

As this is a Phase 2 trial, the goal is to further confirm the safety of these treatments for more patients. Previous studies suggest the treatment is likely well-tolerated, but this trial will verify that. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Most treatments for pancreatic cancer involve chemotherapy drugs like gemcitabine and nab-paclitaxel, which work by attacking rapidly dividing cancer cells. However, researchers are excited about combining these with proglumide, a drug that blocks certain receptors involved in tumor growth and immune system suppression. By adding proglumide, the treatment not only fights the cancer cells directly but also aims to enhance the body's immune response against the tumor. This dual action could potentially make the treatment more effective and provide a new way to tackle pancreatic cancer.

What evidence suggests that this trial's treatments could be effective for pancreatic cancer?

Research shows that using gemcitabine and nab-paclitaxel together may help treat advanced pancreatic cancer. One study found that participants lived for an average of 8.5 months, with their cancer not worsening for about 5.5 months. This trial investigates two treatment arms: one where participants receive a placebo with gemcitabine and nab-paclitaxel, and another where participants receive proglumide with gemcitabine and nab-paclitaxel. Although limited information exists on using proglumide with gemcitabine and nab-paclitaxel, it is believed to affect certain parts of cancer cells that aid their growth. Early signs suggest it might enhance chemotherapy effectiveness, but further research is needed to confirm this. ^{6 7 8 9 10}

In a study of 80 Italian patients with metastatic pancreatic cancer, treatment with nab-paclitaxel in combination with gemcitabine resulted in a median overall survival of 8 months and a median progression-free survival of 5 months, indicating its efficacy.

Nab-paclitaxel was well-tolerated and led to significant pain relief, with reductions in the tumor marker CA 19-9 correlating positively with overall survival, suggesting it may be a useful predictor of treatment outcomes.

Clinical efficacy of nab-paclitaxel in patients with metastatic pancreatic cancer. De Luca, R., Blasi, L., Alù, M., et al.[2022]

Fewer than 20% of pancreatic cancer patients have tumors confined to the pancreas, highlighting the need for effective treatment strategies for advanced disease, as about 40% present with locally advanced cancer.

Gemcitabine is established as the first-line treatment for pancreatic cancer, showing significant clinical benefits, and is being explored in combination with various other agents like 5-fluorouracil and irinotecan to enhance treatment efficacy.

Future directions in the treatment of pancreatic cancer. Haller, DG.[2022]

Recent treatment regimens for advanced pancreatic cancer, including gemcitabine, FOLFIRINOX, and nab-paclitaxel, have shown varying levels of efficacy, highlighting the importance of understanding their unique safety profiles.

Nurses play a crucial role in patient education and symptom management, as each treatment regimen has different adverse events that need to be identified and managed effectively.

In a study of 486 patients with metastatic pancreatic cancer, those receiving nab-paclitaxel plus gemcitabine (nab-p + G) had a median age of 68 and worse performance status compared to those receiving FOLFIRINOX (FFX), who had a median age of 61 and better performance status.

Despite the differences in patient characteristics, the study found no significant differences in time to treatment failure (3.7 months for nab-p + G vs. 4.3 months for FFX) or overall survival (9.8 months for nab-p + G vs. 11.4 months for FFX), suggesting similar efficacy between the two chemotherapy regimens.

In the NAPOLI 3 study involving 770 patients with metastatic pancreatic ductal adenocarcinoma, the NALIRIFOX treatment regimen resulted in a median overall survival of 11.1 months, which was significantly longer than the 9.2 months observed with the nab-paclitaxel and gemcitabine combination.

Both treatment groups experienced a high rate of grade 3 or higher adverse events (87% for NALIRIFOX and 86% for nab-paclitaxel-gemcitabine), indicating that while NALIRIFOX may improve survival, it does not significantly increase the risk of severe side effects compared to the standard treatment.

A retrospective analysis of 59 patients with advanced refractory pancreatic cancer showed that the combination of nab-paclitaxel and gemcitabine (AG) is active as a second-line or beyond treatment, with 10% achieving a partial response and 47% having stable disease.

The median overall survival was 3.9 months and progression-free survival was 3 months, with toxicity levels similar to those reported in the earlier MPACT trial, indicating that AG has manageable side effects in this patient population.

In a study of patients with resected pancreatic ductal adenocarcinoma (PDAC), adjuvant chemotherapy with nab-paclitaxel plus gemcitabine (AG) significantly improved median disease-free survival (15.8 months) and overall survival (28.3 months) compared to gemcitabine alone (12.2 months and 20.6 months, respectively).

While AG showed better survival outcomes, it also led to a higher incidence of sensory neuropathy (53.3% in AG vs. 23.3% in GEM), indicating a trade-off between efficacy and side effects.
