Clinical Trial Summary

Adrenocortical carcinoma is an orphan malignant disease that has a dismal prognosis in advanced stages. Mitotane is the only approved treatment but is limited by severe toxicity. Efficacy of mitotane is unsatisfactory with an objective response rate of ≈20% in monotherapy in selected patients (Megerle et al., JCEM 2018). Cytotoxic chemotherapy with etoposide, doxorubin and cisplatin (EDP) or streptozotocin (Sz) in addition to mitotane (Fassnacht et al., N Engl J Med 2012) succeeded in a progression-free survival of 5.6 months and 2.2 months, respectively in patients with advanced ACC. Objective response rates were 23 and 9%. EDP plus mitotane is therefore considered as standard treatment of ACC. Results by Phan et al. (Cancer Research 2015) demonstrated expression of c-MET and its ligand HGF in ACC and provide a rationale to therapeutically target c-MET in ACC. In a case series of 16 patients with advanced ACC refractory to mitotane (with the exception of one case) and 3 (median, range 0-8)further lines of therapy, single agent treatment with cabozantinib off label resulted in three partial responses and five additional cases of disease stabilization for four months or longer (Kroiss et al., J Clin Endocrinol Metab 2020).

Eligibility

Inclusion criteria:

• Histological confirmation of ACC based on either:

i) Weiss Score of = 3 in patients who had earlier surgical resection (Lin-Weiss-Bisceglia system will be used for oncocytic ACC) OR ii) biopsy results compatible with ACC in the context of clinical setting highly suggestive of ACC (adrenal mass > 4 cm invading surrounding organs or associated with distant metastases).

• Locally advanced or metastatic disease not amenable to surgery with curative intent with measurable disease per RECIST 1.1 37 as determined by the investigator based on an assessment of all known disease sites by computerized tomography (CT) scan or magnetic resonance imaging (MRI) of chest/abdomen/pelvis within 28 days before the first dose of cabozantinib
• Received prior treatment with mitotane and platinum containing chemotherapy. Patients in whom mitotane and/or platinum containing chemotherapy is contraindicated or who refused treatment with mitotane and/or platinum containing chemotherapy are eligible for the study.
• Documented progressive disease.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
• Recovery to baseline or = Grade 1 CTCAE v.5.0 from toxicities related to any prior treatments, unless AE(s) are clinically non-significant and/or stable on supportive therapy
• Life expectancy of at least 3 months
• Adequate organ and bone marrow function and laboratory values as follows within 14

days prior to the first dose of cabozantinib:

1. Absolute neutrophil count (ANC) = 1500/µL without colony stimulating factor support, white blood cell count = 2500/µL.

2. Platelets = 100,000/µL without transfusion

3. Hemoglobin = 9 g/dL

4. Bilirubin = 1.5 × the upper limit of normal (ULN). For subjects with known Gilbert's disease, bilirubin = 3.0 mg/dL

5. Serum albumin = 2.8 g/dl

6. (PT)/INR or partial thromboplastin time (PTT) test < 1.3 x the laboratory ULN

7. Serum creatinine = 2.0 × ULN or creatinine clearance (CrCl) = 30 mL/min. For creatinine clearance estimation, the Cockcroft and Gault equation should be used: Male: CrCl (mL/min) = (140 - age) × wt (kg) / (serum creatinine × 72). Female: Multiply above result by 0.85

8. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) = 3 x upper limit of normal (ULN). In case of liver metastases ALT and AST = 5.0 x ULN are acceptable. ALP = 5 x ULN with documented bone metastases.
