- Maximum Tolerated Dose (MTD) of BI 905711 in Phase 1a
研究概览
简要总结
Phase 1a - 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 1a - Explore pharmacokinetics/pharmacodynamics, and efficacy to guide the determination of a potentially effective dose range for phase Ib in the absence of MTD.
Phase 1b - Evaluate efficacy and safety of BI 905711 at a potentially effective dose range and determine the Recommended Phase 2 Dose (RP2D)

- •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.
排除标准
- •Previous systemic anti-cancer therapy within the specified timeframe from the last dose intake to the first dose of trial treatment as shown below:
- •Any non-investigational drug, including anti-angiogenic antibodies (bevacizumab or ramucirumab) and anti-EGFR antibodies (cetuximab or panitumumab), within 14 days.
- •Any investigational drug or other antibodies including immune checkpoint inhibitors, within 28 days.
- •Radiation therapy within 4 weeks prior to start of treatment. However, palliative radiotherapy for symptomatic metastasis is allowed if completed within 2 weeks prior to start of treatment but must be discussed with the sponsor.
- •Any serious concomitant disease or medical condition affecting compliance with Trial requirements or which are considered relevant for the evaluation of the efficacy or safety of the trial drug, such as neurologic, psychiatric, infectious disease or active ulcers (gastro-intestinal (GI) tract, skin) or laboratory abnormality that may increase the risk associated with trial participation or trial drug administration, and in the judgment of the Investigator, would make the patient inappropriate for entry into the trial. Any history of stroke or myocardial infarction within 6 months prior to screening.
- •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 ≥2 according to CTCAE v5.
- •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:

- •Presence of HBc antibody together with HBV-DNA
- •Presence of hepatitis C RNA
- •Active concomitant malignancies, other than the one treated in this trial.

- •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 institutionalized
- •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 replacement.

- •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 both.
- •Known hypersensitivity to the trial medication and/or its components i.e. polysorbate 20, sodium citrate, lysine hydrochloride, sucrose, citric acid.

结局指标
主要结局
Maximum Tolerated Dose (MTD) of BI 905711 in Phase 1a
时间窗: From cycle 1 Day 1 until the second administration of study treatment (two 14-day treatment cycles).
Maximum tolerated dose (MTD) was defined as the highest dose with less than 25% risk of the true drug limiting dose (DLT) rate being equal to or above 33% during the MTD evaluation period. The MTD was to be considered reached if one of the following criteria was fulfilled: the posterior probability of the true DLT rate in the target interval (0.16, 0.33) of the MTD is above 0.5 or at least 15 patients have been treated in phase 1a, of which at least 6 were at the MTD.
Number of Patients With Dose-limiting Toxicity (DLT) During the MTD Evaluation Period in Phase 1a
时间窗: From cycle 1 Day 1 until the day before cycle 3 Day 1 (two 14-day treatment cycles).
Number of patients with dose-limiting toxicity (DLT) during the MTD evaluation period is reported.
Confirmed Objective Response (OR) for Phase 1a and Phase 1b Combined
时间窗: From the first administration of trial medication until the earliest of progressive disease (PD), death or last evaluable tumor assessment before start of subsequent anti-cancer therapy, up to 48 weeks.
Confirmed objective response (OR) as assessed by the investigator based on Response Evaluation Criteria in Solid Tumors (RECIST 1.1) in patients with measurable disease is reported. This was defined as the best overall response of complete response (CR) or partial response (PR), where best overall response was the best response recorded from the start of the study treatment until the earliest of disease progression, death, or last evaluable tumor assessment and before start of subsequent anticancer therapy.
Progression-free Survival (PFS)
时间窗: From the first administration of trial medication until tumor progression or death, whichever occurred first, up to 48 weeks.
This was evaluated per RECIST 1.1 criteria for target lesions and assessed by CT scan: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions. Overall response at each time point was evaluated by target lesion, non-target lesions and new lesions together, according to RECIST 1.1. Objective response (OR) was defined as best overall response of confirmed CR or confirmed PR according to RECIST 1.1.
