Title:

A Post marketing surveillance study evaluating safety and efficacy of APCEDEN^®, an autologous dendritic cell immunotherapy, when administered according to the prescribing information in India (APASS)

Rationale:

APCEDEN^® is an autologous dendritic cell based cellular immunotherapy product provisionally approved to be used in patients with refractory prostate, colorectal, ovarian or lung cancer. This is the first of its kind product approved in India, and therefore this study is proposed to investigate the short term and long term safety aspect of this product when used as per the prescribing information.

Phase:

Post marketing surveillance study

Study Period:

Sep 2017 –July 2019

Number of patients:

Prostate cancer – 50

Ovarian cancer - 50

Colorectal cancer- 50

Lung cancer- 50

Study design:

Open-label, multi-centre, safety and efficacy study

Centres:

All centres across India, which are eligible to use APCEDEN^®

Indication:

Prostate cancer, Ovarian cancer, Colo-rectal cancer and Lung cancer

Treatment:

 The treatment regimen and the process of APCEDEN^® manufacture starts with aphaeresis of the patient. The peripheral blood mononuclear cells (PBMCs) obtained trough aphaeresis serve as the starting substance for manufacturing, on the 8th day of the aphaeresis the immunotherapy (APCEDEN^®) is ready and supplied to the physician. Patients to receive 6 doses of APCEDEN^® in total. Each dose (0.5 ml ID. and 100 ml IV) at an interval of 15 days.

Primary safety outcome:

·       Overall Survival [Time Frame: From date of subject inclusion to date of death or assessed up to 198 days for ovarian cancer; 87 days for colo-rectal cancer; 184 days for lung cancer; 356 days for prostate cancer]

·       Evaluation of objective response through Immune related Response Criteria (irRC): measure of PD; PR and SD.

·         Immune response as assessed through Treg population and serum IFN-γ levels

·       Monitor treatment emergent adverse events. Safety as assessed by percentage of patients with any Adverse Event (AE), AE leading to Study Drug Discontinuation, AE leading to death, Serious Adverse Event (SAE), AE related to study drug, SAE related to study drug (Time Frame: Every 15 days following first dose for up to 117 days).

Secondary outcome:

·       Quality of life as assessed by the Functional Assessment of Cancer Therapy-General (FACT-G)

·       Evaluation of tumour response as per RECIST. Monitor for evidence of the following tumor responses: Overall response rate (ORR), time to progression (TPP); Progression free survival (PFS) and Disease free survival (DFS)

·       To explore the correlation between APCEDEN^® immune response and overall survival. (Time Frame: Baseline to study completion)

AE of interest

·       Chills, rigour, mild fever, infusion site itching and fatigue
