Safety and Efficacy of Telatinib in Combination With Keytruda in Subjects With Advanced Stomach and Gastroesophageal Junction Cancers or Hepatocellular Carcinoma

Completed · Phase 2

Conditions studied: Gastric Cancer, Hepatocellular Carcinoma

In brief

This is a phase II, single arm, open-label study of two parallel cohorts (advanced stomach and gastroesophageal junction cancer and hepatocellular carcinoma), evaluating the effects of telatinib in combination with Keytruda on progression-free survival.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Diagnosis: Histologically confirmed gastric/esophagealgastric adenocarcinoma, recurrent, locally advanced or metastatic, PD-L1-positive disease (CPS ≥1), progressed on at least two prior lines of therapy and/or discontinued second line therapy for intolerance, indicated for Keytruda therapy. OR: Hepatocellular carcinoma with diagnosis confirmed by histologic or cytologic analysis or clinical features according to the American Association for the Study of Liver Diseases criteria for patients with cirrhosis, unresectable disease not amenable to locoregional therapy with disease progression after at least one prior line of systemic therapy or discontinued first line therapy for intolerance.
At least 1 measurable metastatic lesion that has not been irradiated. The lesion will be measured according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1), and be documented by radiological evaluation within 28 days prior to registration. For subjects with locally advanced disease: at least one measurable lesion that has not been irradiated, documented by radiological evaluation within 28 days prior to registration.
Any prior radiation therapy must be completed at least 28 days prior to the first dose of study treatment.
Eighteen years of age or older.
Eastern Cooperative Oncology Group (ECOG) performance score of 0, 1 or 2.
Adequate bone marrow, liver, and renal function
Negative urine or serum pregnancy test for women of childbearing potential.
Women and men of childbearing potential must agree to use adequate contraception prior to registration, for the duration of study participation and until 4 months after the last study drug dosing.
Able to swallow tablets and agree to take the prescribed tablets twice daily.

You may not qualify if…

Clinical or radiographic evidence of current brain metastasis. History of treated brain metastases is allowable.
Cardiac disease
Uncontrolled hypertension
Severe hemorrhage/bleeding event within 28 days prior to the first dose of study treatment
Major surgery, open biopsy, or significant traumatic injury within 42 days prior to the first dose of study treatment
Current serious, nonhealing wound, ulcer, or bone fracture within 42 days prior to the first dose of study treatment
History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to the first dose of study treatment.
Presence of an uncontrolled infection or infection that required intravenous antibiotics, antifungals, or antivirals within 14 days prior to the first dose of study treatment.
Known human immunodeficiency virus (HIV) infection. HIV-infected subjects on effective anti-retroviral therapy are eligible if the most recent viral load test performed within six months of screening (based on medical chart review) is negative. The safety of telatinib in this subject population has not been studied.
Known chronic hepatitis B, unless receiving antiviral treatment.
Known Child-Pugh Score B or C liver cirrhosis.
Diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study treatment or has been diagnosed with an autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs). Patients that require replacement therapy (e.g., thyroxine [T4], insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) may be enrolled.
History of (non-infectious) pneumonitis that required steroids, or current pneumonitis, or has a history of interstitial lung disease.
Has received a live-virus vaccination within 30 days of planned treatment start.
Known history of proteinuria > 1gr/24 hours.
Previous or concurrent cancer that is distinct in primary site or histology from the current stomach or liver cancer. Subjects with cervical cancer in-situ, treated basal cell carcinoma, superficial bladder tumors (Ta and Tis) or any cancer curatively treated are not excluded.
Anti-cancer therapy (chemotherapy, hormonal therapy, radiation therapy, surgery, immunotherapy, biologic therapy, or tumor embolization) or investigational agent within 28 days prior to the first dose of study treatment.
Known or suspected allergy to any component of telatinib or Keytruda
Prior or current history of substance abuse, or medical, psychological, or social condition that in the opinion of the investigator may interfere with the subject's participation in the study or evaluation of the study result.
Women who are pregnant or breastfeeding.
Prior history of thromboembolic disease, e.g., deep vein thrombosis (DVT), pulmonary emboli (PE), within 6 months prior to the first dose of study treatment that has required continued medical intervention.
Baseline peripheral neuropathy.
