Study of AMG 994 Monotherapy and AMG 994 and AMG 404 Combination Therapy in Participants With Advanced Solid Tumors

Completed · Phase 1

Conditions studied: Advanced Solid Tumors

In brief

The primary objective of this study is to evaluate the safety, tolerability, and maximum tolerated dose (MTD)/maximum tolerated combination dose (MTCD) or recommended phase 2 dose (RP2D) of AMG 994 as monotherapy and AMG 994 in combination with AMG 404 in participants with advanced solid tumors.

You may qualify if…

Participant has provided informed consent/assent prior to initiation of any study specific activities/procedures.
Age ≥ 18 years at the time of signing informed consent.
Life expectancy of > 3 months, in the opinion of the investigator.
Participant must have histologically or cytologically proven metastatic or locally advanced solid tumors of known MSLN expression who have relapsed after and/or are refractory to established and available therapies with known clinical benefit, for which:
No standard systemic therapy exists; or
Standard systemic therapy has failed or is not available.
Dose Expansion (Part 2): Participant must have one of the following malignancies: mesothelioma, pancreatic adenocarcinoma, MSLN positive NSCLC squamous cell carcinoma or adenocarcinoma, high grade serous ovarian carcinoma.
At least 1 measurable or evaluable lesion as defined by modified RECIST 1.1 guidelines.
Participants must be willing to undergo a biopsy prior to enrollment and during treatment with AMG 994.
Participants with treated brain metastases are eligible provided they meet the following criteria:
Definitive therapy was completed at least 2 weeks prior to enrollment.
No evidence of radiographic central nervous system (CNS) progression or CNS disease following definitive therapy and by the time of study screening. Patients manifesting progression in lesions previously treated with stereotactic radiosurgery may still be eligible if pseudoprogression can be demonstrated by appropriate means and after discussion with the medical monitor.
Any CNS disease is asymptomatic, any neurologic symptoms due to CNS disease have returned to baseline, or non-serious CNS diseases that are asymptomatic and deemed irreversible (eg, peripheral neuropathy), the patient is off steroids for at least 7 days (physiologic doses of steroids are permitted), and the patient is off or on stable doses of anti-epileptic drugs for malignant CNS disease and has not had a seizure within 1 month prior to the screening visit.
Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 2.
Hematologic function, as follows (transfusions or growth factor support must not be administered within 7 days prior to obtaining screening labs):
Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
Platelet count ≥ 75 x 109/L
Hemoglobin ≥ 9 g/dL
Adequate renal laboratory assessments, as follows:
Estimated glomerular filtration rate based on Modification of Diet in Renal Disease (MDRD) calculation ≥ 45 mL/min/1.73 m2
Hepatic function, as follows:
Total bilirubin (TBL) ≤ 1.5 x upper limit of normal (ULN) or ≤ 3 x ULN for participants with liver metastasis
Aspartate transaminase (AST) ≤ 3 x ULN or ≤ 5 x ULN for participants with liver metastasis
Alanine aminotransferase (ALT) ≤ 3 x ULN or ≤ 5 x ULN for participants with liver metastasis
Alkaline phosphatase ≤ 2.5 x ULN or ≤ 5 x ULN for participants with liver metastasis

You may not qualify if…

Disease Related
Primary brain tumor, untreated or symptomatic brain metastases and leptomeningeal disease.
Other Medical Conditions
History of other malignancy within the past 2 years, with the following exception[s]:
Malignancy treated with curative intent and with no known active disease present for ≥ 3 years before enrollment and felt to be at low risk for recurrence by the treating physician.
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
Adequately treated cervical carcinoma in situ without evidence of disease.
Adequately treated breast ductal carcinoma in situ without evidence of disease.
Prostatic intraepithelial neoplasia without evidence of prostate cancer.
Adequately treated urothelial papillary noninvasive carcinoma or carcinoma in situ.
Participants with NSCLC squamous cell carcinoma (Part 1), MSLN negative NSCLC squamous cell carcinoma (Part 2), or MSLN negative NSCLC adenocarcinoma (Part 2) once the participant has been screened for MSLN expression.
Participants with sarcomatoid mesothelioma and small cell lung cancer will be excluded from both the Dose Exploration (Part 1) and Dose Expansion (Part 2) parts of the study.
History of solid organ transplantation.
Major surgery within 28 days of study day 1.
Prior/Concomitant Therapy
Anti-tumor therapy (radiotherapy, chemotherapy, antibody therapy, molecular targeted therapy, or investigational agent) within 21 days prior to study day 1.
Treatment with a checkpoint inhibitor within 9 weeks prior to study day 1.
Live vaccine therapy within 4 weeks prior to study drug administration.
Current treatment or within 14 days of day 1 with immunosuppressive corticosteroid defined as > 10 mg prednisone daily or equivalent. Steroids with no minimal systemic effect (such as topical or inhalation) are permitted.
Prior/Concurrent Clinical Study Experience
Currently receiving treatment in another investigational device or drug study, or less than 21 days prior to study day 1 since ending treatment on another investigational device or drug study(ies).
Evidence of active or radiological sequelae of non-infectious pneumonitis.
History of any immune-related colitis. Infectious colitis is allowed if evidence of adequate treatment and clinical recovery exists and at least 3 months interval observed since diagnosis of colitis.
