safety and efficacy of dcb-bo1301 in advanced melanoma

Conditions: Advanced Melanoma

Summary: the primary study objectives are 1. to evaluate the safety and tolerability profiles of dcb-bo1301 and to determine the maximum tolerated dose (mtd) of dcb-bo1301 as add-on therapy to dacarbazine in subjects with advanced melanoma (phase i) 2. to evaluate the efficacy profile of dcb-bo1301 at mtd or lower dose level as add-on therapy to dacarbazine in subjects with advanced melanoma in terms of progression free survival (phase iia)


Eligibility criteria:
inclusion criteria: 1. subjects ≧ 20 years old (inclusive) 2. histologically or cytologically confirmed advanced melanoma, (stage iii or iv) 3. subject must have at least one of the following: * melanoma that was previously treated with at least one complete or partial course of therapy for melanoma with either a poor to no response or evidence of disease progression; * melanoma that cannot be treated with first-line therapies because of medical comorbidities/risk of toxicity; or * melanoma that has not been treated with first-line therapies because of patient refusal. 4. if melanoma is possibly resectable, the melanoma must have recurred despite at least two attempts at resection. 5. evaluable disease, at least one measurable target lesion on imaging by recist 1.1 criteria on previous scan 6. ecog performance status ≤ 2 and life expectancy ≥ 3 months note: ecog = eastern cooperative oncology group 7. females subjects must be either * of non-childbearing potential: * or, if of childbearing potential: * must have a negative urine or serum pregnancy test at screening, and * if heterosexually active, must use at least 1 form of birth control (which must be a barrier method) starting at screening and through the primary study period. 8. female subject must not be breastfeeding at screening, through the treatment period and through the primary study period. 9. male subject and their female spouse/partners who are of childbearing potential must be using highly effective contraception consisting of 2 forms of birth control (1 of which must be a barrier method) starting at screening, through the treatment period and through the primary study period. 10. dated and signed informed consent exclusion criteria: 1. primary cns malignancies or clinically active cns metastases 2. ascertained hypersensitivity to any component of investigational product or standard therapies that the subject will be treated 3. any of the following hematologic abnormalities: 1. hemoglobin \< 10 g/dl, 2. anc \< 1,500/μl, 3. platelets \< 75,000 /μl note: anc = absolute neutrophil count 4. any of the following serum chemistry abnormalities: 1. total bilirubin \> 1.5 × uln, 2. ast, alt, or alk-p \> 2.5 × uln, 3. serum albumin \< 2.5 g/dl, 4. creatinine \> 1.5 × uln, 5. creatine phosphokinase (cpk) \> 2.5 × uln, d. any other ≥ grade 3 laboratory abnormality at baseline (other than those listed above) note: uln = upper limit of normal. ast = aspartate transaminase, alt = alanine transaminase 5. history of known brain metastases 6. anticipated requiring, being taking, or taken with past 2 weeks of screening visit of systemic steroid, immunosuppressive agents, aspirin (more than 100 mg/day), nsaid (except cox-2 inhibitors), heparin, low molecular weight heparin or warfarin (more than 1 mg/day) note: nsaid = nonsteroidal anti-inflammatory drugs 7. uncontrolled nausea or vomiting or any symptom that would prevent the ability to comply with daily oral dcb-bo1301 treatment 8. serious/active infection such as hiv, hbv or hcv carrier, or infection requiring parenteral antibiotics note: hiv = human immunodeficiency virus; hbv = hepatitis b virus; hcv = hepatitis c virus 9. uncontrolled psychiatric disorder or altered mental status precluding informed consent or necessary testing 10. consumption of herbal preparations/supplements (except for a daily multivitamin/mineral supplement not containing herbal components) within 2 weeks prior to the start of dcb-bo1301 administration 11. significant cardiovascular disease, including: 1. active clinically symptomatic left ventricular failure 2. active hypertension (diastolic blood pressure \> 100 mmhg). subjects with a history of hypertension must have been on stable doses of anti-hypertensive drugs for ≥ 4 weeks prior to start of dcb-bo1301 administration 3. uncontrolled hypertension: blood pressure \>140/90 mmhg on more than 2 antihypertensive medications 4. myocardial infarction within 3 months prior to the start of dcb-bo1301 administration 5. prothrombin time \> 1.5 x uln; aptt abnormal (\ 34 sec) ; long qt syndrome 12. significant gastrointestinal disorder(s) that would, in the opinion of the investigator, prevent absorption of an orally available agent 13. has received an investigational agent within 4 weeks of entering this study 14. with any condition judged by the investigator that entering the trial may be detrimental to the subject 15. receiving chemotherapy, investigational or hormonal therapy, major surgeries in the previous 4 weeks of screening visit.
