Details and patient eligibility


Multicenter, open-label, dose-escalation and pharmacokinetic study.

Full description

Multicenter, open-label, phase 1 study of DpC administered orally to patients with advanced solid tumors. The study will be conducted in two parts. In the first phase successive cohorts of patients (3+3) will receive escalating doses of DpC until the maximum tolerated dose (MTD) is reached. MTD is based on tolerability observed during the first 28 days of treatment. The second part of the study involves treatment of expansion cohorts (10-15 patients each) in specific indications to confirm the tolerability of treatment at the recommended phase 2 dose and schedule and evaluate evidence of anti-tumor activity.


14 patients

No Healthy Volunteers

  • Histologically or cytologically confirmed diagnosis of an advanced or metastatic solid tumor for which standard therapy either does not exist or has proven ineffective, intolerable, or unacceptable for the patient;
  • At least one measurable lesion as defined by RECIST v1.1, except for patients with castrate resistant prostate cancer, who may be enrolled with objective evidence of disease per PCWG2 criteria, and patients with ovarian cancer who may be enrolled without measurable disease but who are evaluable by CA125 per GCIC criteria;

  • ferritin at least 50 ug/L;
  • ECHO shows ejection fraction at least 50% and no evidence of cardiac dysfunction;

  • AST/ALT no more than 3 x ULN (5 x ULN if liver or bone involvement);
  • serum albumin at least 28 g/L;
  • INR no more than 1.5 x ULN;
  • At least 3 weeks since chemotherapy, immunotherapy, hormone therapy, r other anticancer therapy or surgical intervention or at least 3 half-lie for monoclonal antibodies;
  • Patients with castrate-resistant prostate cancer must maintain ongoing androgen deprivation therapy to provide serum testosterone <50 mg/dL;
  • Patients receiving bisphosphonate or denosumab therapy must be on stable doses for at least 4 weeks before initiating study treatment.

  • Persistent grade >1 clinically significant toxicities related to prior anticancer treatment (except alopecia);
  • Known primary CNS malignancy or CNS involvement (except for brain mets that have been treated and are stable and patient is off steroids);
  • History of prior to concomitant malignancies (other than fully excised non-melanoma skin cancer, cured in situ cervical carcinoma, early stage bladder cancer or DCIS of breast) within 3 years of study entry;
  • History of atrial fibrillation or evidence of atrial enlargement on baseline ECHO;
  • History of hemoglobinopathy;
  • Current use of iron chelation therapy;
  • Other serious illness or medial condition;
  • Participation in another clinical trial or treatment with any investigational drug within 30 days prior to study entry;
