Phase Ib, Single-arm Study of AZD6094 (Volitinib) in Combination With Docetaxel, in Any Solid Cancer and Sequential Phase II, Single-arm Study of AZD6094 (Volitinib) in Combination With Docetaxel in Advanced Gastric Adenocarcinoma Patients With MET

• Status: Recruiting
• Trial end date: 2020-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Phase Ib/II, single-arm study of AZD6094 (Volitinib) in combination with docetaxel, in advanced gastric adenocarcinoma patients with MET amplification as a second-line treatment.

Phase Ib:Investigational product, dosage and mode of administration Volitinib is an orally available, potent, selective, small molecule c-MET inhibitor.

Volitinib should be administered at least 200mg orally once a day in 21 days for achieving appropriate antitumor activity.

Docetaxel 60 mg/m2 will be administered via intravenous access once every 3 weeks Phase II:

Investigational product, dosage and mode of administration Volitinib is an orally available, potent, selective, small molecule c-MET inhibitor. Subjects will receive Volitinib once daily ( at the MTD determined from Phase Ib) for 21 days as one cycle.

Docetaxel 60 mg/m2 will be administered via intravenous access once every 3 weeks.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

1. Provision of fully informed consent prior to any study specific procedures.

2. Patients must be ≥20 years of age.

3. For Phase Ib: Have histologically or cytologically confirmed diagnosis of relapsed or refractory locally advanced or metastatic solid tumors for whom no alternative effective standard therapy is available or for whom standard therapy is considered unsuitable or intolerable.

• Although it is preferred to enroll patients with solid tumors harboring MET amplification, this will not be an enrollment requirement.

For Phase II: Advanced gastric adenocarcinoma (including GEJ expand and maybe include in list of abbreviations) that has progressed during or after first-line therapy.

• The 1st line regimen must have contained doublet 5-fluoropyrimidine and platinum based regimen.

• Relapse within 6 months of completion of adjuvant/neoadjuvant chemotherapy containing doublet 5-fluoropyrimidine and platinum-based regimen could be considered as 1st line therapy.

• Patients with gastric adenocarcinoma harboring MET amplification by MET FISH.

4. Previous adjuvant/neoadjuvant chemotherapy is allowed, if completed more than 6 months prior to starting the 1st line therapy.

5. Provision or availability of biopsy sample for analysis; e.g mandatory pre-treatment biopsy, or available diagnostic biopsy of sufficient quantity/quality

6. Patients are willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.

7. ECOG performance status 0-1.

8. Patients must have a life expectancy ≥ 3 months from proposed first dose date.

9. Patients must have acceptable bone marrow, liver and renal function measured within 28 days prior to administration of study treatment as defined below:

• Haemoglobin ≥9.0 g/dL (transfusion allowed)

• Absolute neutrophil count (ANC) ≥ 1.5 x 109/L

• White blood cells (WBC) > 3 x 109/L

• Platelet count ≥100 x 109/L (transfusion allowed)

• Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) (does not include patients with Glibert's disease)

• AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present in which case it must be ≤ 5x ULN

• Serum creatinine ≤1.5 x institutional ULN

10. At least one measurable lesion that can be accurately assessed by imaging or physical examination at baseline and follow up visits.

11. Negative urine or serum pregnancy test within 28 days of study treatment, confirmed prior to treatment on day 1 for women of childbearing potential.

12. Provision of consent for mandatory biopsy at progression. (fresh frozen will be mandatory if clinically feasible)

Exclusion Criteria:

1. More than one prior chemotherapy regimen (except for adjuvant/neoadjuvant chemotherapy with more than 6 month wash out period) for the treatment of gastric cancer in the advanced setting.

2. Any previous treatment with MET inhibitors

3. Any previous treatment with docetaxel.

4. Patients with second primary cancer, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for ≤5 years.

5. HER2 positive patients (defined by HER2 3+ by immunohistochemistry or HER2 SISH +)

6. Patients unable to swallow orally administered medication.

7. Treatment with any investigational product during the last 28 days before the enrollment (or a longer period depending on the defined characteristics of the agents used).

8. Patients receiving any systemic chemotherapy, radiotherapy (except for palliative reasons), within 3 weeks from the last dose prior to study treatment (or a longer period depending on the defined characteristics of the agents used). The patient can receive a stable dose of bisphosphonates or denosumab for bone metastases, before and during the study as long as these were started at least 4 weeks prior to treatment.

9. With the exception of alopecia, any ongoing toxicities (>CTCAE grade 1) caused by previous cancer therapy.

10. Intestinal obstruction or CTCAE grade 3 or grade 4 upper GI bleeding within 4 weeks before the enrollment.

11. Resting ECG with measurable QTcB > 480 msec on 2 or more time points within a 24 hour period or family history of long QT syndrome.

12. Patients with cardiac problem as follows: uncontrolled hypertension (BP ≥150/95 mmHg despite medical therapy) Baseline Left ventricular ejection fraction below the LLN of <55% measured by echocardiography or institution's LLN for MUGA, Atrial fibrillation with a ventricular rate >100 bpm on ECG at rest , Symptomatic heart failure (NYHA grade II-IV), Prior or current cardiomyopathy, Severe valvular heart disease, Uncontrolled angina (Canadian Cardiovascular Society grade II-IV despite medical therapy), Acute coronary syndrome within 6 months prior to starting treatment
