The purpose of this trial is to define an effective and safe dose of AP-002 in advanced or
recurrent solid tumors for which there are no standard therapies to use in subsequent studies
in advanced or recurrent breast, non-small cell lung cancer (NSCLC) or prostate cancers.
The Phase 1 portion of this study will determine the Pharmacodynamically Active Dose (PAD) of
AP-002 in humans, defined as the dose at which the plasma concentration of AP-002, as
measured by Ga, is 300-500 ng/mL and which is at or below the Maximum Tolerated Dose (MTD),
to use in the clinical setting of advanced or recurrent solid tumors. This will be followed
by a Phase 2 expanded cohort treated at the PAD, to estimate the efficacy of AP-002 in
patients with advanced or recurrent breast cancer, NSCLC and prostate cancer.
Patients will receive AP-002 orally, once daily for 14 days of a 21 day cycle.
Inclusion Criteria:
1. Phase 1: Patients with advanced or recurrent solid tumors with target (± non-target)
or with only non-target disease, for which there is no standard therapy available
Phase 2: Patients with advanced or recurrent breast cancer, NSCLC, or prostate cancer
with target (± non-target) or with only non-target disease for which there is no
standard therapy available
2. Patients with bone metastases but without target disease are eligible
3. Patients with bone metastases must have at least one bone lesion that has not received
radiation therapy within 6 weeks prior to Cycle 1 Day 1
4. Patients must discontinue bisphosphonate and/or denosumab treatment.
5. Age ≥ 18 years
6. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2
7. O2 saturation ≥ 92% on room air per pulse oximetry
8. Exhaled nitrous oxide ≤ 50 parts per billion (ppb)
9. Adequate hematologic, hepatic and renal function defined as:
1. Hemoglobin ≥ 9 g/dL
2. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L
3. Platelet count ≥ 75 × 109/L
4. Total bilirubin ≤ 2 × upper limit of normal (ULN). Patients with an established
diagnosis of Gilberts syndrome with an unconjugated bilirubin ≤ 2 mg/dL and
conjugated bilirubin within normal limits (WNL) are eligible.
5. Serum electrolytes WNL
6. Transaminases ≤ 3 × ULN
7. Prothrombin time (PT)/international normalized ratio (INR), thromboplastin time
(PTT), or activated PTT (aPTT) ≤ 1.5 × ULN. For patients on therapeutic coumadin,
PT (INR) ≤ 2.5 × ULN is acceptable; for patients on therapeutic heparin, PTT (or
aPTT) ≤ 2.5 × ULN
8. Corrected creatinine clearance ≥ 40 mL/minute, based on the Cockcroft-Gault
equation
10. Patient must have discontinued prior antineoplastic therapy at least 21 days prior to
Cycle 1 Day 1 and have recovered or stabilized from any prior AEs related to the prior
therapy
11. Provision of signed and dated informed consent form
12. Serum 25-hydroxyvitamin D ≥ 30 ng/mL by investigative site laboratory at screening
Exclusion Criteria:
1. Evidence of benign primary hyperparathyroidism, hyperthyroidism, adrenal
insufficiency, vitamin D intoxication, mild alkali syndrome, sarcoidosis or other
granulomatous disease
2. Treatment with calcitonin, mithramycin or cinacalcet within 7 days prior to the date
of the screening
3. Receiving dialysis for renal failure
4. Patients with a known history of clinically significant active infection, including
human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
5. Patients with active central nervous system (CNS) metastases are not eligible, but
patients with treated, stable CNS metastases are allowed
6. Patients with QT interval of ≥ 480 msec on ECG
7. Patients with Paget's disease of bone
8. Patients of childbearing potential unwilling to abstain from sexual intercourse, or
employ effective barrier methods of contraception during participation in this trial
9. Pregnancy or lactation. A negative pregnancy test will be required for women of
childbearing potential prior to study enrollment and will be repeated throughout the
study. Women of childbearing potential will be defined as women who have not had
natural or pharmacologic menopause, nor surgical sterilization.
10. Patients unwilling or unable to take oral medication, requiring a nasogastric or
gastrostomy tube, or unwilling to adhere to the treatment regimen and fasting
requirements
11. Patients unwilling to comply with all study procedures or who are unavailable for the
duration of the study
12. Known allergies to any components of the AP-002 Drug Product
