E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Her2 or cMYC positive advanced oesophagogastric carcinomas |
|
E.1.1.1 | Medical condition in easily understood language |
Cancers arising from either the oesophagus or stomach that display abnormalities of 2 specific genes which are implicated in cancer development: either the Her2 gene, the cMYC gene or both. |
|

MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal research objective is to ascertain whether ibrutinib shows anti-cancer activity in oesophagogastric cancers showing amplifications of either the cMYC gene, the HER2 gene, or co-amplification of both. |
|
E.2.2 | Secondary objectives of the trial |
The secondary research objectives are to assess the safety and tolerability of ibrutinib in patients with oesophagogastric cancers and to correlate the anti-cancer activity of ibrutinib with changes seen on PET-CT scanning.
Further exploratory objectives of ths study include:
-correlating the anti-cancer effect of ibrutinib with changes in DNA and circulating tumour cells in the blood and in the cancer itself through the use additional optional biopsies -correlating the anti-cancer effect of ibrutinib with changes in the HER2 and cMYC genes as well as other proteins that they have an effect on -preparing tissue arrays to develop molecular signatures of response and resistance to ibrutinib treatment -collecting and storing plasma, serum and archival and serial tumour biopsies for potential future exploratory research into factors that may influence development and progression of cancer and/or response to ibrutinib |

Men must agree to not donate sperm during and after the study. For both males and females restrictions apply for 3 month after the last dose of study drug. See protocol for highly effective methods of birth control. -Women of childbearing potential must have a negative serum (beta-human chorionic gonadotropin [b-hCG]) or urine pregnancy test at screening. Women who are pregnant or breastfeeding are ineligible for this study. -Mandatory provision of archival or fresh tumour biopsy for confirmation of c-MYC or HER2 gene amplification. -World Health Organisation (ECOG) performance status 0-2, minimum life expectancy of 12 weeks from proposed first dose date, no deterioration within 2 weeks of screening and first dose. -Adequate organ and haematological function as evidenced by the following laboratory values within 14 days before enrolment:
