A Phase I First-in-Human Study Evaluating Safety, Pharmacokinetics and Efficacy of ABBV 324 in Adults With Hepatocellular Cancer or Squamous Cell Non-Small Cell Lung Cancer
Considering participating in a START clinical trial?
Study Summary
HCC is a common cancer worldwide and a leading cause of cancer-related death. Lung cancer is the most frequently diagnosed cancer in the world, and the leading cause of cancer deaths. The purpose of this study is to assess adverse events and change in disease activity when ABBV-324 is given to adult participants to treat hepatocellular cancer (HCC) or squamous-cell non-small cell lung cancer (LUSC).
ABBV-324 is an investigational drug being developed for the treatment of HCC and LUSC. Study doctors put the participants in groups called arms. Each arm receives ABBV-324 alone (monotherapy) or a comparator drug, lenvatinib followed by a safety follow-up period. Approximately 232 HCC or LUSC will be enrolled in the study in approximately 45 sites worldwide.
In the dose escalation stage participants will be treated with increasing intravenous (IV) doses of ABBV-324 until the dose reached is tolerable and expected to be efficacious. In the dose optimization stage participants will receive ABBV-324, or a comparator of oral lenvatinib. The study will run for a duration of approximately 6.5 years.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.
- * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- * Hepatocellular cancer (HCC) only: Child-Pugh A classification within 7 days before Cycle 1, Day 1 dosing.
- * Laboratory values meeting the criteria outlined in the protocol.
- * QT interval corrected for heart rate (QTc) \< 470 msec (using Fridericia's correction), no Grade 3 arrythmia, and no other clinically significant cardiac abnormalities.
- * Measurable disease per RECIST version 1.1.
- * Part 1 and Part 2 - participants with HCC meeting the following disease activity criteria:
- * Locally advanced or metastatic and/or unresectable HCC with diagnosis confirmed by histology or cytology. Participants with fibrolamellar HCC, sarcomatoid HCC, or mixed cholangiocarcinoma/HCC are not eligible to enroll.
- * Disease that is not amenable to surgical and/or locoregional therapies, or progressive disease after surgical and/or locoregional therapies. For participants who progressed after locoregional therapy for HCC, locoregional therapy must have been completed \>= 28 days prior to baseline scan for the current study.
- * Part 1: Failure of at least 1 prior systemic treatment for HCC.
- * Part 2: Failure of at least 1 prior systemic treatment consisting of an immune checkpoint inhibitor (CPI) containing regimen for HCC, including but not limited to, atezolizumab in combination with bevacizumab or tremelimumab in combination with durvalumab. Note: Participants who have received prior lenvatinib will not be eligible for Part 2.
- * Part 1 only - participants with squamous-cell non-small cell lung cancer (LUSC) meeting the following disease activity criteria:
- * Advanced or metastatic LUSC that is not amenable to surgical resection.
- * Must have failed at least 1 prior line of therapy that included at least platinum-based chemotherapy and an immune CPI, and/or an appropriate targeted therapy (if applicable), or is not suitable for other approved therapeutic options that have demonstrated clinical benefit at the judgment of the investigator. Participants should have no more than 2 lines of prior cytotoxic chemotherapy excluding neoadjuvant and/or adjuvant. Participants who are intolerant of standard therapy are eligible.
- Unresolved clinically significant adverse events (AEs) > Grade 1 from prior anticancer therapy except for alopecia.Untreated brain or meningeal metastases (i.e., participants with history of metastases are eligible provided they do not require ongoing steroid treatment for cerebral edema and have shown clinical and radiographic stability for at least 14 days after definitive therapy). Participants may continue with antiepileptic therapy if required.History of interstitial lung disease (ILD) or pneumonitis that required treatment with systemic steroids, or any evidence of active ILD or pneumonitis on screening chest computed tomography (CT) scan.History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis.History of clinically significant, intercurrent lung-specific illnesses including, but not limited to:Underlying pulmonary disorder (i.e., pulmonary emboli within 3 months of the study enrollment, severe asthma, severe COPD, restrictive lung disease, pleural effusion, dependence on supplemental oxygen, etc.).Any autoimmune, connective tissue or inflammatory disorders with documented or suspicious pulmonary involvement at Screening.Must have discontinued anticancer therapy with antineoplastic intent including chemotherapy, radiation therapy, immunotherapy, biologic, or any investigational therapy within 14 days or 5 half lives of the drug (whichever is shorter) prior to the first dose of ABBV-324. Palliative radiation therapy for bone, skin or subcutaneous metastases with 10 fractions or less is permitted and not participant to a washout period.
