About this trial

This is a Phase II study to determine the rate of stabilization or disease improvement from investigational decitabine/cedazuridine (INQOVI) treatment in subjects with BRCA1-Associated Protein-1 (BAP1) Cancer Predisposition Syndrome (CPDS) and subclinical, early-stage mesothelioma. Progression-free survival (PFS) will also be determined for treated subjects, and the treatment safety (toxicity) evaluated....

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Participants with history of germline BRCA1-Associated Protein-1 (BAP1) mutations.

Histologically confirmed by NCI LP subclinical, early-stage (Tx-T1) mesotheliomas.

Participants with other early-stage BAP1-associated malignancies in addition to subclinical, early-stage mesotheliomas are eligible for study.

The extent of the disease (Tx by radiographic imaging) must be insufficient to warrant approved front-line therapies (surgery, chemotherapy, immunotherapy) per standard of care (SOC). Participants with cT1 tumors may be eligible for study if they have been offered and have refused front-line SOC treatment.

Disqualifiers

Participants with cancers requiring frontline standard of care treatment.

Clinically significant cardiovascular/cerebrovascular disease as follows: cerebral vascular accident/stroke (< 6 months prior to study treatment initiation), myocardial infarction (< 6 months prior to study treatment initiation), unstable angina, congestive heart failure (New York Heart Association Classification Class >= II, serious cardiac arrhythmia, clinically significant bleeding or clinically significant pulmonary embolism.

Therapeutic anticoagulation within 2 weeks prior to study treatment initiation.

Active Hepatitis A (HAV), Hepatitis B (HBV) (e.g., HBsAg reactive), or Hepatitis C (HCV) (e.g., HCV RNA [qualitative] is detected) at screening.

Trial design

Design model

Single group

Treatments tested in this trial

  • Decitabine/cedazuridine

    Drug

    Decitabine/cedazuridine (INQOVI) oral tablet (35 mg decitabine and 100 mg cedazuridine) taken 3 consecutive days during the first week of every cycle (1 cycle=28-days) for 6 cycles (i.e., 1 course). Additional 6 cycles (i.e., Course 2) for subjects with stable disease or disease regression. Max (total) of 2 treatment courses.

Trial outcomes

Primary outcomes

1

To determine stabilization or disease improvement rates in participants with early-stage mesotheliomas arising in the context of BAP1 CPDS following decitabine/cedazuridine treatment

Assessment of thoracoscopy and/or laparoscopy findings demonstrating stability of evaluable disease or improvement compared to baseline

Time frame
baseline, before each cycle, after every 6 treatment cycles (Course 1 and Course 2), and at the safety visit

Secondary outcomes

1

To evaluate the safety of decitabine/cedazuridine

Assessment of safety and tolerability as determined by the frequency and severity of adverse events

Time frame
before each cycle, after every 6 treatment cycles (Course 1 and Course 2), and at the safety visit
2

To determine PFS in participants receiving decitabine/cedazuridine

Progression free survival (PFS) determined by RECIST using the Kaplan-Meier method

Time frame
baseline, after every 6 treatment cycles (Course 1 and Course 2), and until date of progression or last visit ending at the time of the safety visit
