Clinical Trial Summary

The objective of this study is to determine whether a combination of ramucirumab, beyond progression after a SOC 2nd line ramucirumab based pre-treatment (Ram beyond progression) in patients with locally advanced or metastatic adenocarcinoma, plus TAS-102 shows good tolerability without safety issues regarding the serious adverse event rate of any cause, and whether the combination shows positive signals regarding efficacy in the secondary endpoints (e.g. prolongation of progression-free survival of TAS-102 plus ramucirumab compared with TAS-102 monotherapy - historical data according to TAGS trial).

Description:

This is an interventional, prospective, non-randomized, open-label, multicenter single-arm pilot study of ramucirumab plus TAS-102 in patients with advanced or metastatic adenocarcinoma of the stomach or the gastroesophageal junction, after treatment failure on a ramucirumab based therapy.

A total number of 20 patients will be enrolled. Potential study participants will be assessed for eligibility during one or several screening visits. The patient has to provide a signed informed consent form prior to any study-specific screening evaluations. Once the patient provides a signed informed consent form and eligibility is confirmed (all inclusion/exclusion criteria have been verified), the patient can be enrolled.

All screening procedures must be completed during the 14-day screening period. All patients must have had disease status confirmed as per CT or MRI scan of the tumor(s) within ≤ 4 weeks prior to the first dose. Other screening assessments include blood sampling, performance status (ECOG) and ECG according to clinical routine. Study treatment will be continued until progression or intolerable toxicity, but for a maximum of 4 months. Further treatment after progression will be at the investigator's discretion.

Tumor assessment will be performed according to clinical routine at screening and every 8 weeks (±7 days) during the treatment phase of the study and every 12 weeks (±14 days) during follow-up.

The expected duration of the active study phase (FPI - LPO) is 18 months. The active phase per individual patient is approximately 6 months.

Eligibility

Inclusion Criteria:

1. Signed informed consent form.

2. Men or women* = 18 years of age. Patients of reproductive age must be prepared to use a suitable contraceptive method during the study and up to 6 months after the end of treatment. A suitable method of contraception is defined as surgical sterilization (e.g. bilateral fallopian tube ligation, vasectomy), hormonal contraception (implantable, patch, oral), and double barrier methods (each two-fold combination of intrauterine pessary, condom for men, or women with spermicidal gel, diaphragm, contraceptive sponge, cervical cap). Women of child-bearing potential must have a negative pregnancy test within the last 7 days prior to the start of study therapy.

*There is no data that indicates a specific gender distribution. Therefore, patients are included regardless of their gender.

3. Histologically proven adenocarcinoma of the stomach, including adenocarcinoma of the gastroesophageal junction (note: previous histological assessment during disease history of patient sufficient, current biopsy during screening for this trial is not mandatory)

4. Documented, objective, radiological or clinical progression of the disease during or within 4-6 weeks after the last dose of a ramucirumab based second-line therapy (ramucirumab monotherapy or a combination of ramucirumab + paclitaxel, respectively ramucirumab + FOLFIRI).

5. Measurable or non-measurable but evaluable disease.

6. ECOG Performance status 0-2.

7. Life expectancy > 8 weeks.

8. Appropriate haematological, hepatic and renal function:

1. Absolute number of neutrophils (ANC) = 1.5 x 10^9/L

2. Platelets = 100 x 10^9/L

3. Hemoglobin = 9 g/dL (5.58 mmol/L)

4. Total bilirubin = 1.5 times the upper limit of normal (UNL)

5. AST (SGOT) and ALT (SGPT) = 2.5 x UNL without existing liver metastases, or = 5 x UNL in the presence of liver metastases; AP = 5 x UNL

9. Serum creatinine = 1.5 x UNL or creatinine clearance (measured by 24h urine) = 40 mL / min (i.e. if the serum creatinine level is > 1.5 x UNL, then a 24h urine test must be performed to check the creatinine clearance to be determined). Protein level in urine = 1+ by dipstick analysis or routine urine measurement (if the dipstick analysis or the routine test = 2+, a subsequent 24h urine protein measurement must show a value of < 1000mg of protein within 24h of participation to ensure the study.

10. Adequate coagulability, as determined by the International Normalized Ratio (INR) = 1.5 and partial thromboplastin time (PTT) = 5 seconds above the UNL (unless anti-coagulation therapy has been given). Patients receiving warfarin / phenoprocoumon must be switched to low molecular weight heparin and must have a stable coagulation profile before starting study-specific therapy.

11. Subject is willing and able to comply with the protocol (including contraceptive measures) for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

Exclusion Criteria:

1. Presence of tumors other than adenocarcinomas (e.g., leiomyosarcoma, lymphoma) or a secondary tumor other than squamous or basal cell carcinomas of the skin or in situ carcinomas of the cervix which have been effectively treated. The sponsor decides to include patients who have received curative treatment and have been disease-free for at least 5 years.

2. Squamous cell carcinoma of the stomach or gastroesophageal junction.

3. Simultaneous, ongoing, systemic immunotherapy, chemotherapy, or hormone therapy not described in the study protocol.

4. Simultaneous treatment with a different anti-cancer therapy other than that provided for in the study (excluding palliative radiotherapy for symptom control).

5. The patient is receiving chronic antiplatelet therapy, including aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs, including ibuprofen, naproxen, and others), dipyridamole or clopidogrel, or similar agents. Once-daily aspirin use (maximum dose 325 mg/day) is permitted

Clinically significant ascites is defined as ascites resulting from cirrhosis requiring diuretics or paracentesis.
