简要总结
The trial is designed to establish whether adding a vitamin D analogue, Paricalcitol, to standard chemotherapy treatment, Gemcitabine and Nab-paclitaxel, can improve the outcomes for patients with advanced pancreatic cancer.
详细描述
This is an open-label phase II multi-centre single arm study which proposes to test the anti-tumour efficacy of paricalcitol, in combination with GEM/Nab-paclitaxel in patients with advanced metastatic pancreatic cancer.

入选标准
- •Written informed consent obtained prior to any study-related procedures.
- •Incurable recurrent, locally advanced or metastatic pancreatic adenocarcinoma.
- •Histologically or cytologically confirmed pancreatic adenocarcinoma.
- •No prior chemotherapy for incurable, locally advanced unresectable or metastatic pancreatic cancer. Patients may have received prior chemotherapy in the neo-adjuvant or adjuvant setting provided they have a minimum treatment-free interval of 3 months.
- •At least one measurable lesion according to RECIST criteria (Version 1.1). Patients with bone only disease are not eligible.
- •Aged 18 years or older
- •ECOG performance status 0 - 2
- •Adequate haematological, renal and hepatic function measured within 28 days prior to commencing study:
- •Total bilirubin ≤ ULN (or ≤ 3 x ULN (≤ grade 2) for patients with liver involvement)
- •Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x ULN (≤ grade
- •(≤ 5 x ULN for patients with liver involvement by pancreatic cancer).
- •Glomerular filtration rate (GFR) ≥ 30mL/min/1.73 m2 (≤ grade 2) for patients with serum creatinine levels above or below the institutional normal range. If using creatinine clearance, actual body weight should be used for calculating creatinine clearance (e.g., using the Cockroft-Gault formula). For patients with a Body Mass Index (BMI) >30 kg/m2, lean body weight should be used instead.
- •Platelet count ≥ 100 x 109/L.
- •Haemoglobin (Hb) ≥ 8 g/dL (≤ grade 2)
- •Absolute neutrophil count (ANC) ≥ 1.5 x 109/L (≤ grade 1)
- •Corrected serum calcium of ≤ 2.9 mmol/L (≤ grade 1).
- •Life expectancy of at least 12 weeks.
- •Women of childbearing potential and sexually active males must agree to use highly effective contraceptive measures. This applies from starting treatment until at least 6 months after the last study drug administration. The investigator or a designated associate is required to advise the patient how to achieve an adequate birth control. Highly effective contraception is defined in the study as methods that achieve a failure rate of less than 1% per year when used consistently and correctly. Such methods include:
- •i. Combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal). ii. Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable and implantable). iii. Intrauterine device (IUD). iv. Intrauterine hormone-releasing system (IUS). v. Bilateral tubal occlusion. vi. Successfully vasectomised partner. vii. Sexual abstinence.
排除标准
- •Treated with other investigational drugs within 28 days or 5.5 half-lives of treatment start; in addition, concurrent alternative (complementary) medications are excluded within 28 days of treatment start.
- •Known brain metastases, unless previously treated and well-controlled for at least 2 months.
- •Dementia, altered mental status, or any other psychiatric condition that would interfere with the patient's safety or informed consent
- •History of other malignancy other than pancreatic cancer. However, patients who have been disease free from another malignancy for at least 5 years, or patients with a history of resected non-melanoma skin cancer or successfully treated in situ cancer and superficial bladder tumours (Ta, Tis, T1) are eligible.
- •Known history of hypercalcaemia.
- •Presence or history of symptomatic kidney stones in the last 5 years.
- •Active, clinically serious infections > grade 2 (CTCAE v5.0).
- •Greater than or equal to grade 2 sensory or motor neuropathy
- •Uncontrolled intercurrent illness, including, but not limited to uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or social situation that would affect compliance with the requirements of this study.
- •GI tract disease resulting in an inability to take oral medications, malabsorption syndrome, where previous surgical procedures affect absorption and uncontrolled inflammatory bowel disease.
- •History of diseases known to be associated with calcium disorders, including: ongoing hyperparathyroidism and Sarcoidosis.
- •Hypersensitivity to any of the excipients of gemcitabine, Nab-paclitaxel or Paricalcitol.
- •Known vitamin D toxicity
- •Undergoing treatment with the following therapies and medications:
- •Concurrent use of drugs known to influence serum calcium such as thiazide diuretics, teriparatide (recombinant parathyroid hormone), calcitonin and multivitamin supplements containing > 400 IU of vitamin D or calcium.
- •Current use of drugs which could influence bioavailability of paricalcitol (such as magnesium-containing antacids, bile-resin binders).
- •Current use of strong inhibitors of CYP3A4 or CYP2C
- •Current use of inducers of CYP3A4 or CYP2C
- •Phosphate related medicinal products.
- •Zoledronate or denosumab for patients with bone metastasis is allowed. Note patients with bone only disease are not eligible.
- •Calcium intake is not restricted, but calcium supplementation is not permitted.
