Study Overview
Brief Summary
Venous thromboembolic Events (VTEs) are common in lung cancer patients with an incidence of >15%, requiring anticoagulant treatment or prophylaxis. Although direct acting oral anticoagulants (DOACs) are the agents of first choice due to ease and patient friendliness, these drugs are often avoided in cancer patients due to suspected pharmacokinetic drug-drug interactions with oncolytic drugs. Sotorasib is the first KRASG12C inhibitor that has been approved by the US [FDA] and EU [EMA] for the treatment of adult patients with KRAS G12C-mutated locally advanced or metastatic NSCLC. Sotorasib has a potential to cause CYP3A-mediated drug-drug interactions due to induction of CYP3A and inhibition of P-GP. Rivaroxaban is the most frequently prescribed DOAC in the Netherlands. As rivaroxaban is a substrate for this enzyme and efflux pump, sotorasib may increase or decrease the exposure to rivaroxaban and, thus, impact its benefit-to-risk ratio. To enable safe combination of sotorasib and rivaroxaban, it is pivotal to investigate the magnitude of the pharmacokinetic interaction between these drugs.
Detailed Description
Objective:
To assess the pharmacokinetics of single dose rivaroxaban in presence and absence of 960 mg sotorasib at pharmacokinetic steady-state
Main study parameters/endpoints:

- •Clinically significant pathologies of the cardiovascular, bronchopulmonary, neuroendocrine systems, as well as diseases of the gastrointestinal tract, liver, kidneys and blood.
- •Documented history of sensitivity/idiosyncrasy to medicinal products or excipients.
- •Female subject is pregnant or lactating/breastfeeding or planning to become pregnant or breastfeed during treatment and for an additional 7 days after the last dose of sotorasib.
- •Female subjects of childbearing potential unwilling to use an effective method of contraception during treatment and for an additional 7 days after the last dose of sotorasib.
- •Male subjects with a female partner of childbearing potential who are unwilling to practice sexual abstinence (refrain from heterosexual intercourse) or use contraception during treatment and for an additional 7 days after the last dose of sotorasib.
- •Male subjects unwilling to abstain from donating sperm during treatment and for an additional 7 days after the last dose of sotorasib.
- •Consumption of foods and beverages containing poppy seeds, St. Johns Wort, grapefruit, or Seville oranges within 7 days prior to check-in.
- •Concomitant use of drugs, including herbs and food additives, with a pharmacokinetic or pharmacodynamic interaction, as assessed with most recent KNMP kennisbank and uptodate.com drug interaction databases.
- •Donation of plasma or blood (450ml or more) less than 2 months before start of the study.
- •Relevant history or current condition that might interfere with drug absorption, distribution, metabolism or excretion.
- •History of or current abuse of drugs or alcohol.
- •Inability to understand the nature and extent of the study and the procedures required.

- •History of internal bleeding of any genesis.
- •Known present congenital or acquired bleeding disorders.
- •History of liver disease.
- •History suggestive of esophageal (including esophageal spasm, esophagitis), gastric, or duodenal ulceration or bowel disease (including but not limited to peptic ulceration, gastrointestinal bleeding, ulcerative colitis, Crohn's disease, or irritable bowel syndrome); or a history of gastrointestinal surgery other than uncomplicated appendectomy.
- •Known gastrointestinal disease without active ulceration that can potentially lead to bleeding complications.
- •History of vascular retinopathy.
- •Known bronchiectasis.
- •History of pulmonary bleeding.
- •The following conditions known in medical history: coronary heart disease, previous cerebrovascular accident (CVA) or transient ischaemic attack.
- •Positive Hepatitis B Surface Antigen (HepBsAg) (indicative of chronic Hepatitis B or recent acute hepatitis B). Negative HepBsAg with a positive for hepatitis B core antibody (Hepatitis B core antibody testing is not required for screening, however if this is done and is positive, then hepatitis B surface antibody [anti-HBs] testing is necessary. Undetectable anti-HBs in this setting would suggest unclear and possible infection and needs exclusion).
- •Positive Hepatitis C virus antibody: Hepatitis C virus RNA by polymerase chain reaction (PCR) is necessary. Detectable Hepatitis C virus RNA suggests chronic hepatitis C.
