Basic Information

• Recruitment Status: ACTIVE_NOT_RECRUITING
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 62 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-05-31
• Study Completion Date: 2026-05-01

Brief Summary

This is a multicentre, open label, two-part study to determine whether the focal adhesion kinase (FAK) inhibitor AMP945, when given prior to dosing with gemcitabine and nab-paclitaxel, improves response to therapy in first-line patients with unresectable or metastatic pancreatic cancer.

Part A is a phase 1b dose-escalation design that will enrol at least 3 participants in each of 4 dose-level cohorts, to determine the RP2D of AMP945 to be explored in Part B.

Part B will determine the efficacy of the AMP945 regimen at the RP2D, and will be run as a Simon Two-stage design; Stage 1 will enrol 26 participants. If ≤5 of the 26 participants show an objective response, then recruitment will be paused and a detailed analysis of futility will be performed. If the study is deemed futile, recruitment will cease. If the study is determined to be not futile or >5 of the 26 participants show an objective response, recruitment will continue, and an additional 24 participants will be enrolled in Stage 2.

Study Groups

AMP945

Part A: AMP945 administered in dose escalating cohorts Part B: AMP945 recommended phase 2 dose

Group Type: EXPERIMENTAL

AMP945 ascending doses

Intervention Type: DRUG

Part A is a phase 1b dose-escalation design that will enrol at least 3 participants in each of 4 dose-level cohorts, to determine the RP2D of AMP945 to be explored in Part B. Dose escalation decisions will be made using a standard 3+3 dose-escalation phase 1 oncology study design.

AMP945 RP2D

Intervention Type: DRUG

Part B will determine the efficacy of the AMP945 priming regimen at the recommended phase 2 dose (RP2D) determined in Part A.

Eligibility Criteria

Inclusion Criteria

1. Provide written informed consent prior to any study procedures and agree to adhere to all protocol requirements.

2. Aged at least 18 years at the time of consent.

3. Confirmed histological or cytological diagnosis of advanced pancreatic adenocarcinoma that is:

Part A: metastatic or not surgically resectable.

Part B: metastatic, with initial diagnosis of metastatic disease ≤6 weeks prior to Baseline.

4. Has measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >20 mm with conventional techniques or as >10 mm with spiral CT scan.

5. Eligible for treatment with nab-paclitaxel and gemcitabine as standard of care therapy.

6. Eastern Cooperative Oncology Group (ECOG) Performance Score of 0-1, sustained on two separate assessments: the first at least 2 weeks prior to the 1st dose of AMP945 and the 2nd within 72 hours prior to the 1st dose of AMP945. Participants not maintaining an ECOG Performance Score of 0-1 at the second assessment will be excluded from participation.

7. Has a life expectancy of >3 months.

8. Adequate organ function, as defined by the laboratory results below (samples must be obtained ≤14 days prior to study drug administration):

a) Haematology:

(i) Absolute neutrophil count (ANC) ≥1.5 × 109/L;

(ii) Platelet count ≥100,000/mm3 (100 × 109/L);

(iii) Haemoglobin (Hgb) ≥9 g/dL.

b) Serum chemistry:

(i) Aspartate transaminase (AST) (SGOT), ALT (SGPT) ≤2.5 × upper limit of normal range (ULN), unless liver metastases are clearly present, then ≤5 × ULN is allowed;

(ii) Total bilirubin ≤ULN;

(iii) Creatinine <1.5 x upper limit of normal (ULN) or estimated glomerular filtration rate (eGFR) >60 mL/min/1.73m2 (calculated using the Cockcroft-Gault equation).

c) No clinically significant abnormalities in coagulation results.

d) No clinically significant abnormalities in urinalysis results.

9. Agree to use contraception according to protocol

Exclusion Criteria

1. Pregnant or breast-feeding, or plans to become pregnant during the study.

2. Has received any investigational medicinal product (IMP) within 30 days or 5 half-lives (whichever is longer) prior to Day -8.

3. Known brain metastases, unless previously treated and well-controlled for at least 3 months (defined as clinically stable, no oedema, no steroids and stable in 2 scans at least 4 weeks apart).

4. Gastrointestinal condition that could interfere with the swallowing or absorption of study medication.

5. Part A: Has received prior systemic treatments for pancreatic cancer, except those given in the adjuvant setting, and with recurrence more than 6 months after completion of curative/adjuvant treatment.

6. Part B: Has received no previous radiotherapy, surgery, chemotherapy, or investigational therapy for the treatment of metastatic disease. Prior treatment with 5-FU or gemcitabine administered as a radiation sensitizer in the adjuvant setting is allowed, provided at least 6 months have elapsed since completion of the last dose and no lingering toxicities are present. Participants having received cytotoxic doses of gemcitabine or any other chemotherapy in the adjuvant setting are not eligible for this study.

7. History of malignancy other than in situ cancer or basal or squamous cell skin cancer in the last 5 years.

8. Major surgery, other than diagnostic surgery (i.e., surgery done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day -8.

9. Known human immunodeficiency virus (HIV) and/or history of Hepatitis B or C infections or known to be positive for Hepatitis B surface antigen (HBsAg) or Hepatitis C Antibody.

10. Known history of myocardial infarction, coronary stenting, stroke, or cerebrovascular accident within 6 months prior to the first dose of study drug.

11. Focal palliative radiotherapy (e.g., to a bony metastasis) within the 14 days prior to Run-in, or more extensive radiotherapy within 28 days prior to Run-in.

12. History of chronic leukemias (e.g., chronic lymphocytic leukemia).

13. History of interstitial lung disease, history of slowly progressive dyspnoea and unproductive cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, pulmonary hypersensitivity pneumonitis or multiple allergies.

18. Clinically significant allergies to AMP945, nab-paclitaxel or gemcitabine (or any of their excipients), including hypersensitivity reactions to human albumin, that are not likely to be well controlled with premedication or other supportive measures.

19. Exhibiting any of the conditions or events outlined in the Contraindications or Special Warnings and Precautions sections of the nab-paclitaxel and/or gemcitabine package inserts.
