This is a prospective, open-label, single arm translational study of cabazitaxel in bone Castration Resistant metastatic Pancreatic Cancer (mCRPC) patients. Patient will be treated with intravenous (iv) cabazitaxel 25mg/m2 every (q) 21days per standard clinical practice for up to 10 cycles or until disease progression or unacceptable toxicity or physician's decision or patient's consent withdrawal (whichever occurs first).

Eligibility |
Inclusion Criteria: - Male patients older than 18 years - Histologically proven adenocarcinoma of the prostate - Eastern Cooperative Oncology Group (ECOG) performance status 0-2 - Serum testosterone levels < 50ng/ml (1.7 nmol/L) - Ongoing gonadal androgen deprivation therapy with Luteinizing Hormone-Releasing Hormone (LHRH) analogues or orchiectomy. Patients, who have not had an orchiectomy, must be maintained on effective LHRH analogue therapy for the duration of the trial - Progression of disease despite androgen ablation - Either documented osseous or soft tissue metastatic disease progression or by PSA criteria progression - Presence of bone metastases - Off diethylstilbestrol (DES) or steroids treatment for = 4 weeks and for antiandrogens > 4 weeks. - No prior treatment with cabazitaxel - Able to comply with study requirements - Written information delivered to the patient. Patient must be willing and able to comply with protocol requirements. All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must also have signed an authorization for the release of their protected health information. Exclusion Criteria: - Histologic variants in the primary tumor (histologic variants other than adenocarcinoma) - Concurrent therapy with other therapeutic or hormonal agent, including androgen receptor antagonists (bicalutamide, flutamide, nilutamide, enzalutamide), any dose of megestrol acetate (Megace), ketoconazole, abiraterone acetate, finasteride (Proscar), dutasteride (Avodart) any herbal product known to decrease PSA levels (e.g., Saw Palmetto and PC-SPES), - Active infection or intercurrent illnesses that are not controlled - Prior radiation therapy completed < 4 weeks prior to enrolment - Planned palliative procedures for alleviation of bone pain such as radiation therapy or surgery - Structurally unstable bone lesions suggesting impending fracture - Any "currently active" second malignancy, other than non-melanoma skin cancer. Patients are not considered to have a "currently active" malignancy, if they have completed therapy and are considered by their physician to be at least less than 30% risk of relapse over next 3 months - Active psychiatric illnesses/social situations that would limit compliance with protocol requirements. - Active or uncontrolled autoimmune disease that may require corticosteroid therapy during study. - Severely compromised immunological state, including being positive for the human immunodeficiency virus (HIV) - Known acute or chronic hepatitis B or C - Other investigational therapies (targeted or vaccine) will require a 4 week washout period before treatment initiation - ?nitiation of bisphosphonate or denosumab therapy within 4 weeks prior to first dose of study drug. Patients on stable doses of bisphosphonates or denosumab that show subsequent tumor progression may continue on this medication; however, patients are discouraged to initiate bisphosphonate therapy during the study. - Patients receiving an investigational drug within 4 weeks prior to enrolment - History of severe hypersensitivity reaction (grade =3) to polysorbate 80 containing drugs - Uncontrolled severe illness or medical condition (including uncontrolled diabetes mellitus) - Concurrent or planned treatment with strong inhibitors or strong inducers of cytochrome P450 3A4/5 (a one week wash-out period is necessary for patients who are already on these treatments) - Inadequate organ or bone marrow function |

Primary | Molecular effects of treatment with Cabazitaxel on the tumor microenvironment | To explore molecular effects of treatment with Cabazitaxel on the tumor microenvironment of patients with mCRPC in correlation with measures of outcome (ie clinical benefit, Prostate-Specific Androgen (PSA) decline, radiographic response, time to treatment discontinuation), in an effort to identify predictors of response or resistance to therapy. | On week 9 and on week 36 | |
Secondary | Eastern Cooperative Oncology Group (ECOG) performance status | Up to 30 weeks | ||
Secondary | PSA response | Up to 30 weeks | ||
Secondary | Radiological progression-free survival according to Prostate Cancer Working Group 2 (PCWG2) | Up to 30 weeks or until Disease Progression | ||
