What is the purpose of this trial?

This trial tests whether combining new immune therapies with chemotherapy can enhance treatment responses in people with metastatic pancreatic cancer. The focus is on how two immune-based drugs, botensilimab (AGEN1181) and balstilimab (AGEN1884), work with standard chemotherapy and additional medications. Participants must have a confirmed diagnosis of metastatic pancreatic cancer and must not have received prior treatment for it. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive these new therapies.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, patients receiving warfarin or digoxin are excluded, and those on certain immunosuppressive medications or corticosteroids may need to adjust their treatment. It's best to discuss your specific medications with the trial team.

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

Research has shown that the combination of botensilimab and balstilimab holds promise for treating various types of cancer. In previous studies, most patients tolerated these drugs well. Common side effects include tiredness and nausea, but these can be managed.

The chemotherapy drugs in this trial—nab-paclitaxel, gemcitabine, and cisplatin—have long been used in cancer treatment. They may cause side effects like low blood counts and hair loss, but doctors can manage these issues.

Chloroquine and celecoxib are also part of the treatment. Chloroquine, often used for malaria, can rarely cause vision changes. Celecoxib, a pain reliever, might cause stomach upset in some people.

Overall, while each drug has its own possible side effects, the combination has been studied, and safety information is available. Discuss any concerns with the research team before joining the trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine immune-based therapies with chemotherapy to tackle pancreatic cancer in a unique way. Unlike standard treatments such as FOLFIRINOX or gemcitabine with nab-paclitaxel, which primarily target cancer cells directly, this approach uses Balstilimab and Botensilimab to boost the body's immune response against the cancer. These drugs are immune checkpoint inhibitors that may help the immune system recognize and destroy cancer cells more effectively. By also incorporating chemotherapy and additional agents like chloroquine and celecoxib, this treatment aims to enhance the overall anti-cancer effect, potentially offering a new hope for improved outcomes in pancreatic cancer patients.

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

Research has shown that the combination of two drugs, botensilimab and balstilimab, holds promise for treating various cancers, including pancreatic cancer. In other studies, this combination helped 42% of patients with a different advanced cancer live for at least two years, with an average survival time of about 21 months. These drugs enhance the body's immune system to better attack cancer cells. In this trial, participants will receive botensilimab and balstilimab alongside chemotherapy drugs such as nab-paclitaxel, gemcitabine, and cisplatin, as well as chloroquine and celecoxib. Although more research is needed specifically for pancreatic cancer, these early findings are encouraging. ^{1 2 6 7 8}

A study analyzing 2,364 cases of pancreatic adverse events (AEs) linked to immune checkpoint inhibitors (ICIs) found significant associations, particularly with ICI-associated pancreatitis and diabetes mellitus, indicating a notable risk for patients undergoing ICI treatment.

Combination therapy with ICIs showed a higher frequency of pancreatic AEs compared to monotherapy, suggesting that while the risk of these adverse events increases, the fatality rate remains lower, highlighting the importance of patient awareness regarding these potential side effects.

In a phase 3 study involving 800 patients with metastatic pancreatic cancer, ganitumab combined with gemcitabine did not improve overall survival (OS) compared to gemcitabine alone, with median OS of 7.2 months for placebo and similar results for both ganitumab doses (7.0 and 7.1 months).

The combination treatment showed manageable safety with no unexpected toxicities, but circulating biomarkers did not indicate any treatment effect on OS or progression-free survival (PFS).

In a systematic review of 59 randomized controlled trials involving 41,757 patients, immune checkpoint inhibitors (ICIs) were found to be associated with a 0.93% incidence of all-grade pancreatitis and higher rates of pancreatic enzyme elevations, indicating a notable risk of pancreatic adverse events (AEs) during treatment.

The study revealed that PD-1 inhibitors carry a greater risk of pancreatic AEs compared to PD-L1 inhibitors, and patients receiving dual ICI therapy face an even higher risk than those on single ICI therapy, highlighting the need for clinician awareness regarding these potential complications.

The combination of ipilimumab and gemcitabine was found to be safe and tolerable for treating advanced pancreatic ductal adenocarcinoma (PDAC), with a maximum tolerated dose established at ipilimumab 3 mg/kg and gemcitabine 1,000 mg/m2.

Despite the safety of the regimen, the overall response rate was only 14%, indicating that adding ipilimumab does not significantly enhance the effectiveness compared to gemcitabine alone in advanced PDAC.

A study involving 448 patients with advanced cancers showed that immune checkpoint inhibitors, like anti-PD-1 and anti-CTLA4 therapies, are safe and well tolerated across different age groups, including those aged 75 and older.

Older patients (≥75 years) experienced fewer endocrine toxicities compared to younger patients, while they had a higher incidence of dermatological toxicities, indicating that age does not significantly increase the risk of severe adverse effects from these treatments.

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.

In a study of 41 pancreas cancer patients treated with pembrolizumab, the median overall survival was 7.2 months, which is considered favorable compared to the benchmark of over 4 months.

Patients with specific genetic markers (dMMR, MSI-H, TMB-H, or Lynch syndrome) had a significantly lower risk of death, indicating that these biomarkers may help identify patients who could benefit more from pembrolizumab treatment.

In a phase 1b clinical trial involving previously untreated patients with advanced pancreatic ductal adenocarcinoma (PDAC), ibrutinib monotherapy was found to enhance the immune response by increasing activated T cells and monocytes in the blood, indicating its potential to modulate the immune landscape.

However, when ibrutinib was combined with standard chemotherapy (gemcitabine and nab-paclitaxel), these beneficial immune changes were not observed, suggesting that the combination may limit the immunomodulatory effects of ibrutinib.

In a study of 527 patients with advanced nonsmall cell lung cancer receiving PD-1 antibodies, age did not significantly affect the incidence of immune-related adverse events (irAEs) or overall survival, indicating that older patients may tolerate treatment similarly to younger ones.

However, patients aged 75 and older were more likely to have treatment interruptions due to irAEs, which correlated with lower overall survival, suggesting that while age does not affect the likelihood of irAEs, it may impact treatment continuity and outcomes.

In a phase II clinical trial involving 77 patients with advanced pancreatic cancer, the combination of the BTK inhibitor acalabrutinib and the anti-PD-1 antibody pembrolizumab was well tolerated but showed limited clinical activity, with an overall response rate of only 7.9%.

Despite the low efficacy, the treatment led to consistent reductions in myeloid-derived suppressor cells (MDSCs) in peripheral blood, suggesting a potential mechanism for improving immune response in pancreatic cancer that warrants further investigation.
