Drug Information available for: Avelumab

Arm Intervention/treatment
Experimental: Domatinostat plus Avelumab
This is a multicentre open-label, phase II non-randomised clinical trial domatinostat plus avelumab (two separate cohorts in phase IIB part of trial).
Drug: Domatinostat

Domatinostat is an oral tablet which will be given at a variable dose during the Phase IIA safety run in phase of the trial.

During the Phase IIB efficacy phase of the trial patients will be treated with domatinostat at the safe and tolerated combination dose identified during the Phase IIA safety run in phase.

Other Name: 4SC-202

Drug: Avelumab
Avelumab is a monoclonal antibody which is given via an intravenous infusion at a dose of 10mg/kg every two weeks on the first day of a two week cycle. (Day 1 q 14d) from Cycle 2 onwards.




Primary Outcome Measures :
  1. Safety run-in phase: To establish a safe and tolerable dose of domatinostat in combination with avelumab for use in the main (Phase IIB efficacy) phase of the trial [ Time Frame: The DLT period is 28 days following the first treatment with domatinostat and avelumab ]
    Progression through dosing levels will be determined by the occurrence of dose limiting toxicities in the study population.

  2. Main Phase IIB (efficacy) phase: Objective response rate using RECIST 1.1 criteria [ Time Frame: 6 months ]
    ORR defined as the proportion of patients with either CR or PR (assessed according to RECIST 1.1) by 6 months from combination treatment initiation. The best ORR will be presented as a proportion along side a 95% confidence interval


Secondary Outcome Measures :
  1. Number of patients with adverse events (according to NCI-CTCAE version 4) as a measure of safety and tolerability [ Time Frame: Up to 90 days after last dose ]
    Safety of domatinostat and avelumab will be assessed by summarizing adverse events as a proportion

  2. Progression free survival according to RECIST 1.1 [ Time Frame: upto 2 years ]
    PFS will be summarized using Kaplan Meier methods, presenting median survival with 95% confidence intervals. PFS is defined as the time from day of first treatment to disease progression or death from any cause. Patients without an event will be censored on day of last radiological follow up

  3. Overall survival [ Time Frame: upto 2 years ]
    OS will be summarized using Kaplan Meier methods, presenting median survival with 95% confidence intervals. OS is defined as the time from say of first treatment to death from any cause. Alive patients will be censored at the last follow up date

  4. Disease control rate [ Time Frame: At 6 and 12 months on treatment ]
    The proportion of patients with best disease control (CR, PR or SD) at 6 months and 12 months from initiation of combination treatment will be presented with a 95% confidence interval

  5. Duration of objective response according to RECIST 1.1 [ Time Frame: upto 2 years ]
    DoOR will be summarized using Kaplan Meier methods. DoOR is defined as the time between the initial response to treatment and subsequent disease progression or relapse. Patients without an event will be censored on day of last radiological assessment

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria

i. Male/female patients aged ≥18 years ii. Histologically confirmed gastric, gastro-oesophageal junction or oesophageal adenocarcinoma (referred to as oesophagogastric adenocarcinoma (OGA) in this protocol) or colorectal adenocarcinoma (referred to as CRC in this protocol) iii. Agrees to undergo biopsies for translational endpoints iv. Tumour must be mismatch repair proficient assessed using a validated test such as immunohistochemistry for mismatch repair proteins or microsatellite instability testing v. Tumours should be advanced and inoperable or metastatic vi. Patients must have received at least one prior chemotherapy treatment for their cancer, have no established treatment option, or decides against an established treatment option.

vii. Adequate bone marrow function:

  1. Absolute neutrophil count (ANC) ≥1.5 x109/L
  2. White blood count >3x109/L
  3. Platelets ≥100x109/L
  4. Haemoglobin (Hb) ≥9g/dl (can be post-transfusion) viii. Adequate renal function: Creatinine Clearance o ≥30ml/min is required. This may be calculated as per local practice, if calculated CrCl is <60ml/min then EDTA is required to demonstrate CrCl of ≥30ml/min If available, the EDTA clearance should always take precedence over the creatinine clearance.

ix. Adequate liver function

a. Serum bilirubin ≤1.5x ULN b. ALT/AST ≤2.5x ULN or ALT/AST ≤5x ULN if metastatic disease to liver x. Adequate coagulation profile

  1. International Normalised Ratio (INR) < 1.5
  2. Activated Prothrombin Time (APTT) < 1.5xULN xi. Patients on oral anticoagulation are advised to change to low molecular weight heparin prior to study entry to be eligible xii. ECOG performance status 0-1 xiii. Patient is fit to undergo all protocol investigations and receive all protocol treatment based on the assessment oncology clinics xiv. Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all the pertinent aspects of the trial prior to enrolment.

xv. Willingness and ability to comply with the protocol for the duration of the study including scheduled visits, examinations, investigations and treatment plans xvi. Pregnancy must be excluded with a negative serum pregnancy test, within 7 days before initiation of therapy, if the risk of conception exists. Sexually active female patients must be surgically sterile or be postmenopausal or must agree to use highly effective contraception which must be used for 10 days before the negative pregnancy test. Sexually active male patients must be surgically sterile or must agree to use highly effective contraception, i.e. methods with a failure rate of <1% per year (see section 6.4 for full definition and examples of highly effective contraception). Highly effective contraception must be agreed to be used throughout the study and for 30 days after last avelumab treatment if risk of conception exists. Female patients of child-bearing potential should be strictly advised to use a highly effective contraceptive measure, from the time of screening to 30 days after the last dose of trial treatment. If the patient uses a hormonal contraceptive method, the patient's partner should additionally use a condom. Male patients with partners of child bearing potential should be strictly advised to use barrier contraception in addition to having their partner use another method of contraception during the trial and for three months after the last dose. Male patients should also be advised to abstain from sexual intercourse with pregnant or lactating women, or to use condoms.
