What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing four experimental drugs to see if they can help treat pancreatic cancer. The drugs work by blocking important processes that cancer cells need to grow and survive. The trial focuses on patients with pancreatic cancer who do not respond well to standard treatments. Gemcitabine was the first agent investigated for its potential to improve symptoms and overall well-being in pancreatic cancer patients.

Will I have to stop taking my current medications?

The trial requires a 10-day period without taking any previous cancer treatments before starting the study drugs. Additionally, you cannot take certain medications that affect liver enzymes (CYP3A) or those that prolong the QT interval (a heart rhythm measure).

Is targeted drug therapy for pancreatic cancer generally safe in humans?

Cobimetinib, one of the drugs mentioned, was used in combination with another drug in a case report for pancreatic cancer, showing a tumor response, but specific safety data for this combination in humans is not detailed in the provided research. ^{1 2 3 4 5}

How is the drug combination of Cobimetinib, LY3214996, Olaparib, and Onvansertib unique for treating pancreatic cancer?

This drug combination is unique because it targets specific pathways and molecules involved in the growth and spread of pancreatic cancer cells, unlike traditional chemotherapy that attacks all rapidly dividing cells. Cobimetinib, for example, is a MEK inhibitor that has shown promise in targeting specific mutations in pancreatic cancer, offering a more tailored approach to treatment. ^{2 6 7 8 9}

What evidence supports the effectiveness of the drug combination including Cobimetinib, Cotellic, LY3214996, Temuterkib, Olaparib, Lynparza, and Onvansertib for pancreatic cancer?

There is some evidence that the combination of the BRAF inhibitor vemurafenib and the MEK inhibitor cobimetinib showed a positive tumor response in a patient with a specific type of advanced pancreatic cancer. However, overall, targeted therapies have not shown significant benefits for most pancreatic cancer patients, and the effectiveness of the specific drug combination in the trial is not directly supported by the available research. ^{1 2 10 11 12}

Published Research Related to This Trial

Complete surgical resection is the only potentially curative option for pancreatic cancer, but most patients are diagnosed with advanced disease, leading to a median survival of only 6 months with standard gemcitabine-based therapy.

Recent phase III trials have shown that combining gemcitabine with erlotinib or capecitabine significantly improves overall survival compared to gemcitabine alone, indicating potential new strategies for treating advanced pancreatic cancer.

The combination of cediranib and olaparib did not show clinically meaningful activity in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who do not have a known BRCA mutation, as no objective responses were observed in the study of 19 patients.

Despite some patients experiencing stable disease for a median of 3.1 months, the overall survival was only 3.4 months, indicating limited efficacy of this treatment combination in this patient population.

Pancreatic cancer has a very low 5-year survival rate of less than 7%, and current therapies have not significantly improved patient outcomes, with median overall survival (MoS) for standard treatments like gemcitabine and fluorouracil being around 23 months.

Some clinical trials of new small molecule inhibitors show promise, such as a phase I trial with vorinostat and capecitabine achieving a MoS of 13 months, and a phase II trial of pazopanib showing a MoS of 25 months, indicating potential for improved treatment strategies.

Recent advances in targeted therapy and immunotherapy show promise for treating pancreatic ductal adenocarcinoma (PDAC), which is often diagnosed at advanced stages and has limited treatment options.

Combining these new therapies may enhance treatment effectiveness and improve patient outcomes, as supported by current preclinical and clinical evidence.

A patient with advanced pancreatic ductal adenocarcinoma harboring a V600E BRAF mutation showed an objective tumor response to a combination treatment of the BRAF inhibitor vemurafenib and the MEK inhibitor cobimetinib.

This case highlights the potential for targeted therapy in a small subset of pancreatic cancer patients, suggesting that BRAF mutations, although rare, may offer a new avenue for treatment beyond conventional chemotherapy.

In a phase II trial involving 32 patients with untreated metastatic pancreatic cancer, the combination of erlotinib and capecitabine showed an overall response rate of 6% and a median overall survival of 4.3 months, indicating limited efficacy.

The treatment demonstrated a favorable safety profile, with major non-hematological toxicities being manageable (skin rash, asthenia, and diarrhea), and no grade 4 toxicities or treatment-related deaths reported.

In a phase II trial involving 17 patients with advanced pancreatic cancer, the combination of sorafenib and gemcitabine showed no objective responses, with only 18% of patients achieving stable disease.

The treatment resulted in a median overall survival of 4.0 months and was associated with significant toxicities, including thrombosis in 18% of patients, indicating that this combination is not effective for this type of cancer.

The combination of gemcitabine, capecitabine, bevacizumab, and erlotinib showed promising efficacy in treating advanced pancreatic cancer, with 10 partial responses observed among 20 patients and median overall survival of 12.5 months.

The maximum-tolerated dose of capecitabine was determined to be 1,660 mg/m², with a recommended dose of 1,440 mg/m² for further studies, while the treatment was generally well-tolerated with manageable side effects like diarrhea and skin rash.

Dovitinib, when combined with gemcitabine and capecitabine, was found to be safe at a recommended dose of 300 mg daily, with manageable side effects such as fatigue and neutropenia in a study involving 29 patients with advanced pancreatic and biliary tract cancers.

The combination treatment showed promising efficacy, with partial responses observed in 5 patients, indicating potential benefits for those suffering from advanced pancreatic cancer.

Erlotinib, a targeted therapy that inhibits the epidermal growth factor receptor, has been approved for use alongside gemcitabine in treating advanced pancreatic cancer, marking a significant step in personalized cancer treatment.

Despite the exploration of various targeted agents, most have shown limited success, highlighting the need for therapies tailored to the specific molecular characteristics of both the patient and the tumor.

In a study involving 745 patients with advanced pancreatic cancer, adding the EGFR-targeted drug cetuximab to standard gemcitabine therapy did not significantly improve overall survival compared to gemcitabine alone, with median survival times of 6.3 months versus 5.9 months, respectively.

Despite 90% of patients showing positive EGFR expression, there was no observed treatment benefit from cetuximab, suggesting that targeting EGFR may not be effective and highlighting the need to explore alternative therapeutic targets for pancreatic cancer.
