What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is overseen by Johns Hopkins clinical research office. Team members at each location will report any major issues to the lead researcher.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

Is the CA19-9 test safe for humans?

The CA19-9 test, used as a marker for pancreatic cancer, is generally safe for humans as it involves measuring a substance in the blood. However, it is not always accurate, as it can give false positive or negative results, especially in people with certain genetic traits. ^{1 2 3 4 5}

How does this treatment for pancreatic cancer differ from other treatments?

This treatment is unique because it focuses on using glycan-based biomarkers, specifically sialyl-Lewis A (sLeA) and sialyl-Lewis X (sLeX), to improve the detection and classification of pancreatic cancers. Unlike the standard CA19-9 biomarker, which is not elevated in about 25% of pancreatic cancer cases, this approach can identify additional cancer cases by detecting related glycans, potentially leading to more accurate diagnosis. ^{1 2 6 7 8}

What data supports the effectiveness of the treatment CA19-9 for pancreatic cancer screening?

CA19-9 is the most commonly used biomarker for diagnosing pancreatic cancer in symptomatic patients and monitoring therapy, although it has limitations such as false negatives and positives. It is currently the best validated serum tumor marker for pancreatic cancer, despite not being a perfect screening tool. ^{1 2 3 5 9}

Published Research Related to This Trial

CA19-9 is the most validated serum tumor marker for diagnosing pancreatic cancer and monitoring treatment, but it has limitations such as false negatives in individuals with the Lewis (a-b-) genotype and false positives in benign conditions.

Despite the emergence of many potential biomarkers for pancreatic cancer, none have proven to be as effective as CA19-9, which remains the only clinically used marker despite its moderate positive predictive value of 72.3%.

CA 19-9: Biochemical and Clinical Aspects. Scarà, S., Bottoni, P., Scatena, R.[2022]

A new panel of glycan biomarkers, including sialyl-Lewis X and a sialylated form of type 1 N-acetyl-lactosamine, shows improved diagnostic accuracy for pancreatic cancer compared to the traditional CA19-9 antigen, achieving 85% sensitivity and 90% specificity in a study of 200 subjects.

This new biomarker panel outperforms CA19-9, which has a sensitivity of only 54% and a specificity of 86%, highlighting its potential for better early detection of pancreatic cancer in distinct patient subsets.

Glycans related to the CA19-9 antigen are elevated in distinct subsets of pancreatic cancers and improve diagnostic accuracy over CA19-9. Tang, H., Partyka, K., Hsueh, P., et al.[2019]

Lewis-negative pancreatic cancer patients (5-10% of individuals) have a poorer prognosis, with higher metastatic rates and lower CA19-9 expression compared to Lewis-positive patients, based on a study of 853 patients.

Molecular analysis revealed that Lewis-negative cancer cells exhibit higher proliferation and migration rates, along with distinct morphological features, indicating they represent a more aggressive form of pancreatic cancer.

Lewis antigen‑negative pancreatic cancer: An aggressive subgroup. Liu, C., Deng, S., Jin, K., et al.[2021]

In a study involving 578 pancreatic cancer patients, 210 with benign pancreatic disease, and 315 normal subjects, using Lewis and Secretor genotype-dependent cut-off values significantly improved the sensitivity of CA19-9 for detecting pancreatic cancer from 80.1% to 88.0%.

The optimized CA19-9 detection method also enhanced the sensitivity for early-stage pancreatic cancer (stage I and II) from 76.1% to 87.2%, indicating that adjusting cut-off values based on genetic factors can improve early detection of this aggressive cancer.

A new glycoprotein antigen associated with pancreatic cancer was identified, showing elevated levels in patients with pancreatic cancer compared to those with other diseases and normal subjects, indicating its potential as a diagnostic marker.

The assay developed for this antigen, utilizing both monoclonal antibodies and specific lectins, could enhance the accuracy of pancreatic cancer diagnosis by targeting unique cancer-associated glycoconjugates.

The study identified the CA 19-9 ganglioside antigen in tumors from 16 pancreatic cancer patients, confirming it as a sialyl Lewis(a) ganglioside through mass spectrometry.

There was a significant correlation between serum CA 19-9 levels and the presence of the ganglioside antigen in tumors, suggesting that serum levels may reflect tumor characteristics rather than overall tumor burden.

Sialyl Lewis(a) ganglioside in pancreatic cancer tissue correlates with the serum CA 19-9 level. Hamanaka, Y., Hamanaka, S., Suzuki, M.[2019]

The study highlights that different CA 19-9 antibodies have varying specificities, which can significantly impact their effectiveness in detecting pancreatic cancer, as shown through antibody arrays comparing samples from cancer patients and controls.

One antibody was found to bind not only to the canonical CA 19-9 epitope but also to a related structure, sialyl-Lewis C, allowing for better detection of cancer patients without increasing false positives from pancreatitis cases, suggesting that antibody specificity is crucial for improving cancer biomarker performance.

Diverse monoclonal antibodies against the CA 19-9 antigen show variation in binding specificity with consequences for clinical interpretation. Partyka, K., Maupin, KA., Brand, RE., et al.[2021]

CA19-9 is a key biomarker for pancreatic cancer with about 80% sensitivity, but its effectiveness can be limited by false positives in inflammatory conditions and false negatives in individuals lacking the Lewis antigen, highlighting the need for careful interpretation in clinical settings.

Beyond its role as a biomarker, CA19-9 can promote cancer progression through mechanisms like enhancing angiogenesis and immune response, making it a promising target for therapeutic strategies such as antibodies, vaccines, and nanoparticles.

Roles of CA19-9 in pancreatic cancer: Biomarker, predictor and promoter. Luo, G., Jin, K., Deng, S., et al.[2023]

The study identified that sialyl-Lewis X (sLeX), a structural isomer of the current pancreatic cancer biomarker sialyl-Lewis A (sLeA), is elevated in the plasma of some pancreatic cancers that do not show elevated sLeA levels, potentially improving early diagnosis.

A two-marker panel combining sLeA and sLeX detection achieved 79% accuracy in differentiating pancreatic cancers from benign diseases, outperforming sLeA alone, which had 68% accuracy, suggesting that glycan-based biomarkers could enhance clinical diagnosis of pancreatic cancer.
