Phase Ia - Explore safety and establish the maximum tolerated dose (MTD)/recommended dose
levels for phase Ib expansion phase of BI 905711 based on the frequency of patients
experiencing dose limiting toxicities (DLTs) during the MTD evaluation period. The MTD
evaluation period is defined as the first two treatment cycles (from first dose
administration until the day preceding the third dose administration or end of REP in case of
discontinuation before start of Cycle 3).
Phase Ia - Explore pharmacokinetics/pharmacodynamics, and efficacy to guide the determination
of a potentially effective dose range for phase Ib in the absence of MTD.
Phase Ib - Evaluate efficacy and safety of BI 905711 at a potentially effective dose range
and determine the Recommended Phase 2 Dose (RP2D)
- Histologically or cytologically confirmed, advanced unresectable or metastatic
gastrointestinal cancers of following histologies:
- Colorectal adenocarcinoma
- Gastric adenocarcinoma
- Esophageal adenocarcinoma
- Pancreatic adenocarcinoma
- Patient who has failed all available conventional therapies known to confer clinical
benefit for their disease based on local approved standards. For patients with
colorectal cancer, prior treatment with regorafenib or TAS-102 is optional.
- Phase Ia (dose escalation) only: Patient with either measurable or
- Phase Ia (expanded cohort) and Phase Ib (expansion phase) only: At least one target
lesion that can be accurately measured per RECIST v.1.1
- Availability and willingness to undergo tumor biopsy before treatment to provide tumor
tissue. Pre-treatment fresh tumor biopsy collections for biomarker analyses are
considered optional in phase Ia and mandatory in phase Ib. However, fresh tumor
biopsies will NOT be considered if significant risk procedures are required including
(but not limited to) biopsies of the pancreas, or endoscopic procedures extending
beyond the esophagus, stomach or bowel. Only non-significant risk procedures per the
investigator's judgment will be used to obtain any biopsies specified in this study.
In case a fresh tumor biopsy cannot be obtained due to before mentioned reasons an
archived tumor tissue specimen needs to be submitted.
- Adequate hepatic, renal and bone marrow functions as defined by all of the below:
- Total bilirubin (= 1.5 x institutional ULN (= 3 x institutional ULN for patient
with Gilbert's syndrome)
- ALT and AST =2.5 x institutional ULN (=5 x institutional ULN for patients with
known liver metastases)
- Serum creatinine =1.5x institutional ULN. If creatinine is > 1.5 x ULN, patient
is eligible if concurrent creatinine clearance = 50 ml/min (measured or
calculated by CKD-EPI formula or Japanese version of CKD-EPI formula for Japanese
- ANC = 1.0x 10^9/L
- Platelets = 100x10^9/ L
- Hb =9.0 g/dl (without transfusion within previous week)
- Serum lipase = 1.5 institutional ULN
- Recovery from any adverse events of previous anti-cancer therapies to baseline or
CTCAE grade 1, except for alopecia CTCAE grade 2, sensory peripheral neuropathy CTCAE
grade = 2 or considered not clinically significant.
- ECOG performance status = 1
- Life expectancy = 3 months in the opinion of the investigator
- Of legal adult age (according to local legislation) at screening
- Signed and dated written informed consent in accordance with ICH-GCP and local
legislation prior to admission to the trial.
- Male or female patients. Women of childbearing potential (WOCBP) and men able to
father a child must be ready and able to use highly effective methods of birth control
per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used
consistently and correctly.
- Treatment with a systemic anti-cancer therapy or investigational drug within 14 days
or 5 half-lives (whichever is shorter) of the first treatment with the study
- Radiation therapy with extensive large field involving parenchymal organs in chest,
abdomen or pelvis within 3 weeks of the first treatment in the study. There is no
restriction for minor small field radiotherapy.
- Any history of or concomitant condition that, in the opinion of the investigator,
would compromise the patient's ability to comply with the study or interfere with the
evaluation of the safety or efficacy of the test drug.
- Known pathological condition of GI tract, liver and pancreas, excluding the disease
under study, that may interfere with assessment of drug safety or may increase the
risk of toxicity:
- inflammatory bowel disease
- chronic pancreatitis
- other serious GI pathological conditions by judgment of the investigator e.g.
autoimmune disease with GI involvement, unexplained active diarrhea CTCAE grade
- Known history of human immunodeficiency virus infection.
- Any of the following laboratory evidence of hepatitis virus infection. Test results
obtained in routine diagnostics are acceptable if done within 14 days before the
informed consent date:
- Positive results of hepatitis B surface (HBs) antigen
- Presence of HBc antibody together with HBV-DNA
- Presence of hepatitis C RNA
- Active concomitant malignancies, other than the one treated in this trial.
- Patients who require anticoagulation therapy with heparin or low molecular weight
heparin (LMWH). Therapy with factor Xa inhibitors, direct thrombin inhibitors, and
warfarin is allowed. Patients receiving warfarin must have their INR values closely
monitored according to institutional guidelines.
- Chronic alcohol or drug abuse or any condition that, in the investigator's opinion,
makes the patient an unreliable trial participant or unlikely to comply with the
protocol requirements or not expected to complete the trial as scheduled.
- Women who are pregnant, nursing, or who plan to become pregnant while in the trial;
female patients who do not agree to the interruption of breast feeding from the start
of study treatment to within 30 days after the last study treatment.
- Presence of uncontrolled or symptomatic brain or subdural metastases. Inclusion of
patients with brain metastases who have completed local therapy and are considered
stable by the investigator, or with newly identified asymptomatic brain metastases at
screening will be allowed. Use of corticosteroids is allowed if the dose was stable
for at least 1 week before the baseline MRI.
- Patients who are under judicial protection and patients who are legally
- Major surgery (major according to the investigator's assessment) performed within 3
weeks prior to treatment start or planned within 3 months after screening, e.g. hip
- Any of the following cardiac criteria:
- Mean resting corrected QT interval (QTc) >470 msec
- Any clinically important abnormalities (as assessed by the Investigator) in
rhythm, conduction, or morphology of resting ECGs, e.g., complete left bundle
branch block, third degree heart block
- Patients with an ejection fraction (EF) <50% or the lower limit of normal of the
institutional standard will be excluded. Only in cases where the Investigator (or
the treating physician or both) suspects cardiac disease with negative effect on
the EF, will the EF be measured during screening using an appropriate method
according to local standards to confirm eligibility (e.g., echocardiogram,
multi-gated acquisition scan). A historic measurement of EF no older than 6
months prior to first administration of study drug can be accepted provided that
there is clinical evidence that the EF value has not worsened since this
measurement in the opinion of the Investigator or of the treating physician or
- Known hypersensitivity to the trial medication and/or its components i.e. polysorbate
20, sodium citrate, lysine hydrochloride, sucrose, citric acid.
