Clinical Trial Summary

This is a non-randomised study in patients with advanced solid malignancies

Description:

The aim is to recruit approximately 8 patients with a minimum number of 4 pharmacokinetics (PK) evaluable patients. Each patient will be admitted to the study site pre-dose on Day -1 and will remain at the study site until at least Day 8. Patients will receive a single administration of [14C]adavosertib as an oral solution on Day 1. During this study, whole blood, plasma, urine, faeces, and vomit samples (if presented) will be collected at various time points to characterise the absorption, distribution, metabolism, excretion and PK of adavosertib. The duration of the residential period will be evaluated following treatment of the first patient and may be adjusted to ensure recovery of at least 90% of the total radioactivity following the dose of [14C]adavosertib and/or until less than 1% of dose is recovered in urine and/or faeces within a 24-hour period.

Eligibility

Inclusion Criteria:

9. Males and females of childbearing potential who agree to use contraceptive measures consistent with local regulations for clinical studies.

Exclusion Criteria:

1. Persistent toxicities (Common Terminology Criteria for Adverse Events [CTCAE] Grade > 2) caused by previous anticancer therapy, excluding alopecia and CTCAE Grade 2 peripheral neuropathy.

2. Refractory nausea and vomiting, chronic gastrointestinal disease, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption, distribution, metabolism, or excretion of 14C-adavosertib oral solution.

3. Patients who have participated in another absorption, distribution, metabolism and excretion study within 1 year prior to screening.

4. Any significant cardiac diseases currently or within the last 6 months such as:

1. unstable angina pectoris

2. acute myocardial infarction, congestive heart failure

3. conduction abnormality not controlled with pacemaker or medication

4. significant ventricular or supraventricular arrhythmias

5. Any of the following: History or current evidence of congenital long QT syndrome; concomitant medications known to prolong QT interval or history of medication-related QT prolongation.

6. Known to have tested positive for human immunodeficiency virus or active tuberculosis infection.

7. Known active hepatitis infection, positive hepatitis C antibody, hepatitis B virus surface antigen or hepatitis B virus core antibody, at screening.

8. Any evidence of diseases (such as severe or uncontrolled systemic diseases, including uncontrolled hypertension, renal transplant, active infections, and active bleeding diseases) which prohibit participating in the study.

9. Spinal cord compression or brain metastases unless asymptomatic, stable, and not requiring steroids for at least 4 weeks prior to start of study intervention.

10. Use of an anti-cancer treatment drug = 21 days (= 6 weeks for nitroureas or mitomycin C) or use of an investigational product within 5 half-lives prior to the first dose of adavosertib.

11. Patient uses drugs that are sensitive to CYP3A4 substrates or CYP3A4 substrates with a narrow therapeutic index, or are moderate to strong inhibitors/inducers of CYP3A4 which cannot be discontinued 2 weeks or 5 halflives (whichever is longer) prior to Day 1 of dosing.

12. Receipt of live virus and live bacterial vaccines whilst the patient is receiving the study intervention and during the 30-day follow-up period. Inactivated flu vaccines are permitted.

13. Any known hypersensitivity or contraindication to the components of the study intervention adavosertib.

14. Currently pregnant (confirmed with positive pregnancy test) or breast feeding.
