Phase III Study of DCVAC/PCa Added to Standard Chemotherapy for Men With Metastatic Castration Resistant Prostate Cancer
|
A Randomized, Double Blind, Multicenter, Parallel-group, Phase III Study to Evaluate Efficacy and Safety of DCVAC/PCa Versus Placebo in Men With Metastatic Castration Resistant Prostate Cancer Eligible for 1st Line Chemotherapy
|
The VIABLE study sought to confirm the hypothesis that the combination of docetaxel with DCVAC/PCa followed by a maintenance therapy with DCVAC/PCa would improve overall survival in patients with metastatic castration-resistant prostate cancer.
|
This was a randomized, double blind, placebo-controlled, multicenter, international, parallel-group phase III study. Patients with metastatic castration-resistant prostate cancer who were candidates to receive standard of care first-line chemotherapy with docetaxel plus prednisone were randomized 2:1 into one of two arms: an investigational arm (DCVAC/PCa) and a control arm (placebo) in addition to chemotherapy (docetaxel plus prednisone).

- Biological: DCVAC/PCa
DCVAC/PCa concurrently with docetaxel plus prednisone every 3 weeks (± 7 days). DCVAC/PCa was administered at least 7 days before or and at least 7 days after the nearest chemotherapy (days 8-15 of chemotherapy cycles). After discontinuation of chemotherapy for any reason, each following dose of DCVAC/PCa was given every 4 weeks (-7/+14 days) for up to a total of 15 doses.
Other Name: Stapuldencel
- Biological: Placebo
Placebo concurrently with docetaxel plus prednisone every 3 weeks (± 7 days). Placebo was administered at least 7 days before or and at least 7 days after the nearest chemotherapy (days 8-15 of chemotherapy cycles). After discontinuation of chemotherapy for any reason, each following dose of placebo was given every 4 weeks (-7/+14 days) for up to a total of 15 doses.

- Experimental: DCVAC/PCa with standard of care chemotherapy
Combination therapy with DCVAC/PCa and standard of care chemotherapy (docetaxel and prednisone)
Intervention: Biological: DCVAC/PCa
- Placebo Comparator: Placebo with standard of care chemotherapy
Combination therapy with placebo and standard of care chemotherapy (docetaxel and prednisone) as comparator
Intervention: Biological: Placebo

Inclusion criteria:
- Male 18 years and older.

- Confirmed pathological fracture related to the disease OR
- Confirmation of distant bone and/or soft-tissue and/or visceral metastases on CT or MRI scan or bone scintigraphy OR
- Positive pathology report of metastatic lesion
-
Disease progression despite androgen-deprivation therapy (ADT) as indicated by:
- Prostate-specific antigen (PSA) increase that is ≥ 2 ng/mL and ≥ 25% above the minimum PSA as reached during ADT or above the pre-treatment level, if no response was observed and which is confirmed by a second value 1 or more weeks later OR
- Progression of measurable lymph nodes (short axis ≥ 15 mm) or visceral lesion measurable per RECIST v1.1 criteria, confirmation by an independent review facility (IRF) required OR
- Two or more new lesions appearing on bone scan/imaging compared with a previous scan (confirmation by IRF required)
- Maintenance of castrate conditions: patients, who have not had a surgical orchiectomy, must continue with hormone therapy with gonadotropin releasing hormone/ luteinizing hormone-releasing hormone (GnRH/LHRH) agonists or antagonists to reach levels of serum testosterone of ≤ 1.7 nmol/L (50 ng/dL). The duration of the castration period must be at least 4 months before screening as evidenced by combination of clinical/laboratory data (see section 6.8.1).
-
Laboratory criteria:
- White blood cells (WBC) greater than 4,000/mm3 (4.0 x109/L)
- Neutrophil count greater than 1,500/mm3 (1.5 x109/L).

- Platelet count of at least 100,000/mm3 (100 x 109/L).
- Total bilirubin within normal limits (benign hereditary hyperbilirubinemias, e.g. Gilbert's syndrome, are permitted).
- Serum alanine aminotransferase, aspartate aminotransferase, and creatinine < 1.5x times the upper limit of normal (ULN).

- At least 4 weeks after surgery or radiotherapy before randomization.
- A minimum of 28 days beyond initiation of bisphosphonate or denosumab therapy before randomization.
- Recovery from primary local surgical treatment, radiotherapy or orchiectomy before randomization.
- Signed informed consent including patient's ability to comprehend its contents.
Exclusion criteria:
- Confirmed brain and/or leptomeningeal metastases (other visceral metastases are acceptable).
- Current symptomatic spinal cord compression requiring surgery or radiation therapy.

Patient co-morbidities:
- Systemic corticosteroids at doses greater than 40 mg hydrocortisone daily or equivalent for any reason other than treatment of PCa within 6 months before randomization.
- Ongoing systemic immunosuppressive therapy for any reason.
- Treatment with anti-androgens, inhibitors of adrenal-produced androgens or other hormonal tumor-focused treatment performed on the day of randomization (except for GnRH/LHRH agonists or antagonists) to exclude possible anti-androgen withdrawal response. This criterion is not applicable to subjects who have never responded to anti-androgen treatment, as there is no risk of anti-androgen withdrawal response.
- Treatment with immunotherapy against PCa within 6 months before randomization.
- Treatment with radiopharmaceutical within 8 weeks before randomization.
- Participation in a clinical trial using non-immunological experimental therapy within 4 weeks before randomization.
- Participation in a clinical trial using immunological experimental therapy (e.g., monoclonal antibodies, cytokines or active cellular immunotherapies) within 6 months before randomization.
