Aldoxorubicin

PFS is defined as the time from the date of randomization to first documentation of objective tumor progression, according to RECIST 1.1 Criteria, or to death due to any cause in the absence of previous documentation of objective tumor progression. For subjects without documentation of objective tumor progression, who started other anti-tumor treatment, or lost to follow up/withdrew consent prior to confirmed progression, PFS is censored at the date of the last tumor assessment. PFS is defined as the interval from the date of randomization to the earliest date of documented evidence of recurrent or progressive disease, or the date of death due to any cause, whichever occurs first. PD is defined as: 20% increase in the sum of the longest diameter of target lesions from the smallest sum of the longest diameter recorded since the treatment started; the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of 1 new lesion is also considered PD.

Objective responses were evaluated using the Response Evaluation Criteria In Solid Tumors 1.1 (RECIST 1.1). Changes (ie, improvements) in tumor measurements from baseline values were assigned a status of CR or PR or SD. Objective response measurements comprised the sum of CR plus PR. Complete Response (CR): disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm). Partial Response (PR): \>=30% decrease in the sum of the longest diameter of target lesions, from the baseline sum longest diameter.

Progression-free survival is defined as the interval from the date of registration (ie, assignment of subject number) to the earliest date of documented evidence of recurrent or progressive disease, or the date of death due to any cause, whichever occurs first. Progressive Disease is defined as: 20% increase in the sum of the longest diameter of target lesions from the smallest sum of the longest diameter recorded since the treatment started; the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of 1 new lesion is also considered progression.

The primary objective of this study is to determine the preliminary safety of administration of aldoxorubicin in combination with gemcitabine in subjects with metastatic solid tumors as measured by the frequency and severity of adverse events (AEs), abnormal findings on physical examination, laboratory tests, vital signs, echocardiograms (ECHO) or multiple-gated acquisition (MUGA) scans, electrocardiogram (ECG) results, and weight.

Blood samples will be obtained for pharmacokinetics. Standard pharmacokinetic parameters, including t1/2, Cmax, AUC, Vd and CL, will be determined.

The primary objective of this study is to determine the preliminary safety and maximum tolerated dose (MTD) of aldoxorubicin plus doxorubicin HCl in subjects with advanced solid tumors who have failed standard therapies.

Safety will be based on adverse events, tolerability, physical examinations, vital signs, ECG results, laboratory test results. MTD: If 2 of 5 subjects an any dose level experiences a grade 3 or 4 non-hematologic toxicity, or a platelet count \<25,000/uL or a neutrophil count \<500/uL lasting \>7 days and/or associated with fever \>38.5C, 3 more subjects will be entered at that dose level. If 2 of 3 of the additional subjects experience any of the above adverse events, the dose level immediately below will be identified as the MTD.
