Safety and Efficacy of RVU120 Combined With Venetoclax for Treatment of Relapsed/Refractory AML

Conditions
Summary
The goal of this study is to assess the safety, tolerability, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of RVU120 when administered in combination with venetoclax to adult patients with acute myeloid leukemia (AML) who are relapsed or refractory to prior therapy with venetoclax and a hypomethylating agent. The study consists of three parts. Part 1 aims to identify the doses of RVU120 and venetoclax that are considered to be safe and tolerated. Part 2 will assess the safety and efficacy of the doses selected. And Part 3 is a confirmatory cohort where patients will be treated at the same doses assessed in Part 2

- Evidence of ongoing or uncontrolled systemic bacterial, fungal or viral infection and acute inflammatory conditions (including pancreatitis)
- Ongoing significant liver disease such as cirrhosis, drug-induced liver injury, active hepatitis, or chronic persistent hepatitis B and/or hepatitis C
- Ongoing drug-induced pneumonitis
- Significant cardiac dysfunction, defined as myocardial infarction within 12 months prior to the first dose of study drug, NYHA (New York Heart Association) Class III or IV heart failure, uncontrolled dysrhythmias, poorly controlled angina
- History of ventricular arrhythmia or QTc ≥ 470 ms (Bazett's formula)
- Prior history of malignancies other than AML, unless disease-free for 5 years or more or prior basal cell carcinoma of the skin, non-metastatic squamous cell carcinoma of the skin, carcinoma in situ of cervix, breast or bladder, and incidental histological finding of prostate cancer (TMN stage T1a or T1b)
- Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of RVU120 and/or venetoclax
- Taking any medications, herbal supplements, or other substances (including smoking( that are known to be strong inhibitors or moderate/strong inducers or sensitive substrates of CYP1A2
- Taking any medications, over-the-counter medications, foods or herbal supplements that are known to be strong or moderate inhibitors of CYP3A4 or P-gp (P-glycoprotein)
- Known allergy or hypersensitivity to any component of RVU120 or venetoclax formulations
Interventions
RVU120 is a potent, selective inhibitor of CDK8 and its paralog CDK19
Venetoclax specifically binds to BCL-2, displacing proapoptotic proteins and triggering events that lead to apoptosis
