Investigation of the Effects of Diet on the Measurement of Plasma Chromogranin in NET Patients

Measurement of plasma chromogranin A remains the most commonly used biomarkers for both screening and monitoring of patients with gastro-entero-pancreatic neuroendocrine tumours (GEP-NET), despite several limitations that include: lack of a reference CgA standard; wide variations depending on the used assay in different laboratories; and varying sensitivity ranges from 60 to 90% with low specificity 10 hours overnight fast, in a randomised double-crossover design. The investigators aimed to include 25 – 35 patients with a histologically confirmed diagnosis of a GEP-NET of varying primary tumour location, tumour stage, grade; and presence or absence of treatment with long acting somatostatin analogues; as well as 10 – 15 healthy controls. In an additional small subgroup of patients who are initiated on treatment with GLP-1 analogues i.e. for type 2 diabetes or obesity, the investigators aim to establish whether injection of GLP-1 analogues has any effects on plasma CgA measurements.

Trial of First-line L-glutamine With Gemcitabine and Nab-paclitaxel in Advanced Pancreatic Cancer

This study will enroll a total of 16 patients with advanced pancreatic cancer at Cedars-Sinai Medical Center. All subjects will receive combination therapy of gemcitabine, nab-paclitaxel, and L-glutamine. The study investigates what the appropriate dosage of L-glutamine is so that there is the lowest risk of side effects, and whether the supplement will make standard chemotherapy of gemcitabine and nab-paclitaxel more effective in treating advanced pancreatic cancer.

Evaluation of SBRT for Patients With Locally Advanced Unresectable Pancreatic Cancer

The aim of this phase II study is to assess the efficacy and safety of sequentially integrated treatment of FOLFIRINOX or Gemcitabine-Abraxane and SBRT in patients with unresectable pancreatic cancer.

Study of Gemcitabine and Erlotinib Plus Sorafenib (GES) in Metastatic Pancreatic Cancer

This study tests the combination of two targeted therapies,along with chemotherapy treatment in the treatment of pancreatic cancer.

Serum DCAMKL1 Pre and Post Treatment in Patients With Pancreatic Cancer

The investigators believe DCAMKL-1 is a stem cell tumor marker and is elevated in patients with pancreatic cancer. The investigators would like to analyze its expression pre and post treatment, to gauge the correlation between current pancreatic cancer therapies and the expression of DCAMKL-1

Neoadjuvant vs Upfront Surgery for Resectable Pancreatic Cancer and Periampullary Cancer

Adjuvant chemotherapy after surgery significantly improved the survival of pancreatic cancer (PC) patients, but there is a problem that only about 50% of patients start adjuvant chemotherapy after pancreatectomy. Neoadjuvant chemotherapy might control potential metastatic lesions which are not being detected in early disease status and improve the R0 resection rate. In addition, it prevents futile surgery by selecting patients with rapid progression of disease. Furthermore, compared to chemotherapy administered after surgery, more patients can complete the planned chemotherapy schedule in neoadjuvant setting.

There are still few studies worldwide that prospectively explored the efficacy of neoadjuvant chemotherapy in resectable PC and periampullary cancer and the administration of neoadjuvant therapy in resectable PC depends on individual clinical judgment. Therefore, systematic and prospective clinical trials are essential to standardize treatment protocol in resectable PC and periampullary Cancer.

This randomized controlled trial compares neoadjuvant chemotherapy followed by surgery versus upfront surgery for patients with clearly resectable pancreatic head cancer and periampullary cancer. The study aims to determine if neoadjuvant chemotherapy improves overall survival compared to immediate surgery followed by adjuvant chemotherapy.

Personalized Vaccine with SOC Chemo Followed by Nivo in Pancreatic Cancer

Phase Ib clinical trial using Autologous Dendritic Cell Vaccine Loaded with Personalized Peptides (PEP) in order to stimulate/induce both innate and adaptive immunity by activating T-cells and Natural Killer (NK) cells, combined with standard of care (SOC) adjuvant chemotherapy, followed by nivolumab, an antibody against Programmed Cell Death 1 (PD-1), to maintain and boost the vaccine's effect in patients with non-metastatic resectable pancreatic adenocarcinoma

Neoadjuvant GTX With Chemoradiation for Pancreatic Cancer (Stage II/III)

This study is for patients with locally advanced pancreatic cancer (cancer that involves the local blood vessels so it cannot be removed without cutting major blood vessels) that cannot be treated with surgery. The purpose of this study is to assess the safety and benefit of 6 three week cycles of chemotherapy treatment consisting of gemcitabine, capecitabine and docetaxel (also called 'GTX'). The patients fall into two groups. Group I are those with only venous involvement. Group II patients have arterial involvement and may also have venous involvement. If there is arterial involvement, GTX will be followed by 5 and 1/2 weeks of radiation therapy with gemcitabine and capecitabine. After the chemotherapy and radiation treatment, participants may be able to have surgery to remove any remaining pancreatic cancer.

Gemcitabine Versus Reduced-dose Combination Chemotherapy in Fragile Patients with Non-resectable Pancreatic Cancer

The aim of the study is to compare the efficacy and toxicity of full-dose Gemcitabine and reduced-dose combination chemotherapy in patients with non-resectable pancreatic cancer, who are unfit for full-dose combination chemotherapy.

The patients will be equally randomized to arm A or arm B:

Arm A: Full-dose single agent treatment with Gemcitabine 1000 mg/m2 weekly on days 1, 8,and 15 every 4 weeks.

Arm B: Reduced-dose (80%) combination-treatment with Gemcitabine plus Nab-Paclitaxel (Gemcitabine: 800 mg/m2 plus Nab-Paclitaxel: 100 mg/m2 on day 1, 8 and 15 every 4 weeks)

Progression-free survival, overall survival and response rate will be estimated for each group, as well as toxicity and quality of life will be prospectively registered.

Pilot Study of Autologous T-cells in Patients With Metastatic Pancreatic Cancer

This is a study in which pancreatic cancer patients receive a combination therapy with CART-meso cells and CART19 cells administered at 3 days after one dose of cyclophosphamide. CART-meso cells are patients' own T cells that were modified in the laboratory to express a receptor specific to the mesothelin protein. CART19 cells are patients' own T cells that were modified in the laboratory to express a receptor specific to a protein called CD19. The CD19 protein is expressed on white blood B cells. CART19 cells are expected to attack the B cells and impede the antibody response against CART-meso cells. The investigators hypothesize that this combination therapy may prolong the duration of CART-meso cells in the body. Additionally, one dose of cyclophosphamide may enhance engraftment and persistence of CART cells.
