Title of the Protocol:  
A Multicenter, Randomized, Open-Label Phase 2b Study to Investigate the Efficacy and Safety of 
Aldoxorubicin Compared to Topotecan in Subjects with Metastatic Small Cell Lung Cancer Who 
Either Relapsed or Were Refractory to Prior Chemotherapy 
Primary Objective: 
The primary objective of this study is to determine the efficacy of administration of aldoxorubicin 
compared to topotecan in subjects with metastatic small cell lung cancer (SCLC) who have relapsed 
or were refractory to prior chemotherapy, as measured by progression-free survival (PFS). 
Secondary Objectives: 
The secondary objectives of this study are to evaluate the efficacy of aldoxorubicin as measured by 
overall survival (OS), safety of aldoxorubicin compared to topotecan in this population assessed by 
the frequency and severity of adverse events (AEs), abnormal findings on physical examination, 
laboratory tests, vital signs, echocardiogram (ECHO) evaluations, electrocardiogram (ECG) results, 
and weight, as well as disease control rate and tumor response. 
Study Rationale and Significance: 
Aldoxorubicin (INNO-206; DOXO-EMCH) is a novel prodrug that binds covalently to albumin in the 
circulation. The drug is accumulated in tumors and doxorubicin is released in the tumor by cleaving 
the acid labile linker (EMCH) in the low pH tumor environment.  This carrier-linked prodrug has 
demonstrated enhanced antitumor activity with reduced toxicity in several murine models when 
compared with free doxorubicin. 
Patients with metastatic SCLC who have failed prior chemotherapies have a poor prognosis with 
response rates of <10-25%, PFS of around  2-4 months and median OS of approximately 6-10 
months, depending on the initial duration of response to first line treatment.  Several chemotherapy 
regimens have been explored as palliative therapy for subjects with these patients and include such 
agents as topotecan (only approved agent in the US), topotecan plus platinum, cyclophosphamide + 
doxorubicin + vincristine (CAV) and amirubicin (not approved in US). However, these regimens can 
be quite toxic and have not significantly impacted either PFS or OS in these individuals.  
Aldoxorubicin may improve upon the activity of these drugs without an increase in toxicity as has 
been demonstrated in animal studies.

Study Design and Methodology: 
This is a phase 2b open-label study evaluating the efficacy and safety of aldoxorubicin administered 
at 230 mg/m2 (170 mg/m2 doxorubicin equivalent) intravenously on Day 1 every 21 days compared to 
topotecan administered either IV at doses of 1.5 mg/m2/day for 5 consecutive days starting on Day 1, 
and repeated every 21 days, or 4 mg/m2 administered as a 30 min IV infusion on Days 1, 8 and 15 
every 28 days. Subjects will be randomized 1:1 to receive either aldoxorubicin or topotecan. 
Pretreatment with granulocyte colony-stimulating factor (G-CSF) is permitted according to ASCO 
Guidelines (Appendix E).[31]  
Subjects will visit the study site on Day 1 of each cycle. Safety monitoring, including AEs, a directed 
physical examination, laboratory evaluations (serum chemistry, complete blood count [CBC], and 
urinalysis), vital signs, weight measurements, Eastern Cooperative Group performance status (ECOG 
PS) and ECGs will be performed on Day 1 of each cycle (for all subjects).  They will have CBCs and 
serum chemistries on Day 15 and Day 21 (if Day 21 does not correspond to Day 1 of the next cycle, 
±3 days) of each cycle as well. Cardiac function will also be followed periodically (per schedule of 
evaluations) with ECHO for subjects receiving aldoxorubicin. Treatment will continue until tumor 
progression is observed, subject asks to withdraw, or unacceptable toxicity occurs.  
Tumor response will be monitored at baseline, every 6 weeks from Cycle 1-Day 1 through week 33, 
and then every 12 weeks until disease progression using the Response Evaluation Criteria in Solid 
Tumors (RECIST) 1.1 criteria.[22] Overall survival, PFS, and PFS at 4 and 6 months will be evaluated. 
Objective response rate (ORR; complete response [CR] and partial response [PR]), disease control 
rate (ORR plus stable disease [SD] at 4 months) and quality of life (ECOG PS) will be assessed.

Number of Subjects: 
Approximately 132 subjects with metastatic SCLC who have either not responded to or have 
progressed after treatment with no more than 1 prior systemic regimens will be randomized 1:1 
(aldoxorubicin:topotecan) at approximately 30 study centers in the US, Europe, and Asia. The 
randomization will be stratified according to their initial PS (ECOG PS 0-1 vs 2), and whether they 
had relapsed < or > 90 days after completing their initial therapy. 
Test Product and Mode of Administration: 
Aldoxorubicin: Lyophilized powder in vials that contain 200 mg of aldoxorubicin reconstituted by 
adding a solution of 50% ethanol: 50% sterile water, administration completed within 2 hours (of 
being reconstituted) as a 30 minute IV infusion in Lactated Ringer’s solution.  Total dose of 
230 mg/m2 (170 mg/m2 doxorubicin equivalent). 
Topotecan:  
Topotecan for Injection is supplied as a sterile lyophilized, buffered, light yellow to greenish powder 
available in single-dose vials. Each vial contains topotecan hydrochloride equivalent to 4 mg of 
topotecan as free base. The reconstituted solution ranges in color from yellow to yellow-green and is 
intended for administration by intravenous infusion (IVI). Each topotecan 4-mg vial is reconstituted 
with 4 mL Sterile Water for Injection. Then the appropriate volume of the reconstituted solution is 
diluted in either 0.9% Sodium Chloride IVI or 5% Dextrose IVI prior to administration. Because the 
lyophilized dosage form contains no antibacterial preservative, the reconstituted product should be 
used immediately.  
Criteria for Evaluation: 
Efficacy: 
The following efficacy variables will be evaluated as noted: 
 PFS 
 OS 
 Objective tumor response (RECIST 1.1 criteria).[22] 
 Disease control rate (ORR + SD at 4 months). 
 Investigator assessment as measured by ECOG PS.

Phase of Development: 2b 
 
Safety: 
The following safety variables will be assessed over the duration of the study: 
 AEs 
 Ability to remain on assigned treatment (tolerability). 
 Clinical and laboratory data including physical examinations, vital signs, weight, ECHO 
evaluations, ECG results and laboratory test results. 
 Use of concomitant medications. 
Statistical Methods: 
In accordance with the intention-to-treat principle, all randomized subjects will be evaluated for 
efficacy. All subjects who receive at least 1 dose of study medication will be evaluated for safety.  
Efficacy:   
The primary analysis of PFS will be carried out approximately 6 months following the completion of 
enrollment of 132 subjects. Survival distributions will be estimated using the Kaplan-Meier method 
and the 2 groups will be compared using a two-sided log rank test at the α=0.05 level of significance. 
The final analysis of OS will be completed when 110 OS events have occurred. Survival distributions 
will be estimated using the Kaplan-Meier method and the 2 groups will be compared using a two-
sided log rank test. 
Tumor response will be monitored at baseline, every 6 weeks from Cycle 1-Day 1 through week 33, 
and then every 12 weeks until disease progression. The percentage of subjects with CR or PR, or SD 
will be evaluated and the disease control rate (CR, PR and SD at 4 months) will be compared using 
Pearson’s chi-square test, or if 20% or more of the expected cell frequencies are less than 5, Fisher’s 
exact test. Investigator reported outcomes as assessed by the ECOG PS will be analyzed using 
analysis of covariance. 
Subjects in each group will be stratified according to their initial PS (ECOG PS 0-1 vs 2) and whether 
they had progressed in less than or greater than 90 days after their initial chemotherapy. 
Sample Size Justification: 
Power calculations and subject numbers were calculated based on the primary endpoint of PFS.  
Reviewing the literature for studies that have evaluated topotecan as treatment for patients that have 
relapsed or not responded to first line therapies, it is estimated that the median PFS for the topotecan 
group will be 3.5 months and that the median PFS for the aldoxorubicin group will be 6.5 months.  
Based on the use of a two-sided log rank test at the α=0.05 level of significance, a total of 110 PFS 
events will be required for 90% power to detect this difference.  Assuming an 18 month accrual period 
and a 6 month follow-up period after enrollment of the last subject, approximately 132 subjects will be 
needed to achieve the total of 110 PFS events. 
Safety:  
The safety data will be summarized by treatment group.  The treatment groups will be compared with 
respect to occurrence of each AE. Total number of AEs leading to withdrawal, and abnormal 
laboratory tests will be compared between groups using Fisher’s exact test. Adverse events, ability to 
remain on assigned treatment (tolerability), and abnormal findings on physical examinations, vital 
signs, weight, ECG results, laboratory test results, and use of concomitant medications, will be 
assessed to characterize the safety profile of the treatment regimens. Descriptive statistics denoting 
the changes from baseline to the final assessment visit with respect to key laboratory parameters and 
vital signs will also be provided.

Number of Subjects: 
Approximately 132 subjects with metastatic SCLC who have either not responded to or have 
progressed after treatment with no more than 1 prior systemic regimens will be randomized 1:1 
(aldoxorubicin:topotecan) at approximately 30 study centers in the US and Europe. The 
randomization will be stratified according to their initial PS (ECOG PS 0-1 vs 2), and whether they 
had relapsed < or > 90 days after completing their initial therapy. 
Test Product and Mode of Administration: 
Aldoxorubicin: Lyophilized powder in vials that contain 200 mg of aldoxorubicin reconstituted by 
adding a solution of 50% ethanol: 50% sterile water, administration completed within 2 hours (of 
being reconstituted) as a 30 minute IV infusion in Lactated Ringer’s solution.  Total dose of 
230 mg/m2 (170 mg/m2 doxorubicin equivalent). 
Topotecan:  
Topotecan for Injection is supplied as a sterile lyophilized, buffered, light yellow to greenish powder 
available in single-dose vials. Each vial contains topotecan hydrochloride equivalent to 4 mg of 
topotecan as free base. The reconstituted solution ranges in color from yellow to yellow-green and is 
intended for administration by intravenous infusion (IVI). Each topotecan 4-mg vial is reconstituted 
with 4 mL Sterile Water for Injection. Then the appropriate volume of the reconstituted solution is 
diluted in either 0.9% Sodium Chloride IVI or 5% Dextrose IVI prior to administration. Because the 
lyophilized dosage form contains no antibacterial preservative, the reconstituted product should be 
used immediately.  
Criteria for Evaluation: 
Efficacy: 
The following efficacy variables will be evaluated as noted: 
 PFS 
 PFS at 4 and 6 months 
 OS 
 Objective tumor response (RECIST 1.1 criteria)[22] 
 Disease control rate (ORR + SD at 4 months) 
 Investigator assessment as measured by ECOG PS

Safety: 
The following safety variables will be assessed over the duration of the study: 
 AEs 
 Ability to remain on assigned treatment (tolerability) 
 Clinical and laboratory data including physical examinations, vital signs, weight, ECHO 
evaluations, ECG results and laboratory test results 
 Use of concomitant medications 
Statistical Methods: 
In accordance with the intention-to-treat principle, all randomized subjects will be evaluated for 
efficacy. All subjects who receive at least 1 dose of study medication will be evaluated for safety.  
Efficacy:   
The primary analysis of PFS will be carried out approximately 6 months following the completion of 
enrollment of 132 subjects. Survival distributions will be estimated using the Kaplan-Meier method 
and the 2 groups will be compared using a two-sided log rank test at the α=0.05 level of significance. 
The final analysis of OS will be completed when 110 OS events have occurred. Survival distributions 
will be estimated using the Kaplan-Meier method and the 2 groups will be compared using a two-
sided log rank test. 
Tumor response will be monitored at baseline, every 6 weeks from Cycle 1-Day 1 through week 36, 
and then every 12 weeks until disease progression. The percentage of subjects with CR or PR, or SD 
will be evaluated and the disease control rate (CR, PR and SD at 4 months) will be compared using 
Pearson’s chi-square test, or if 20% or more of the expected cell frequencies are less than 5, Fisher’s 
exact test. Investigator reported outcomes as assessed by the ECOG PS will be analyzed using 
analysis of covariance. 
Subjects in each group will be stratified according to their initial PS (ECOG PS 0-1 vs 2) and whether 
they had progressed in less than or greater than 90 days after their initial chemotherapy. 
Sample Size Justification: 
Power calculations and subject numbers were calculated based on the primary endpoint of PFS.  
Reviewing the literature for studies that have evaluated topotecan as treatment for patients that have 
relapsed or not responded to first line therapies, it is estimated that the median PFS for the topotecan 
group will be 3.5 months and that the median PFS for the aldoxorubicin group will be 6.5 months.  
Based on the use of a two-sided log rank test at the α=0.05 level of significance, a total of 110 PFS 
events will be required for 90% power to detect this difference.  Assuming an 18 month accrual period 
and a 6 month follow-up period after enrollment of the last subject, approximately 132 subjects will be 
needed to achieve the total of 110 PFS events. 
Safety:  
The safety data will be summarized by treatment group.  The treatment groups will be compared with 
respect to occurrence of each AE. Total number of AEs leading to withdrawal, and abnormal 
laboratory tests will be compared between groups using Fisher’s exact test. Adverse events, ability to 
remain on assigned treatment (tolerability), and abnormal findings on physical examinations, vital 
signs, weight, ECG results, laboratory test results, and use of concomitant medications, will be 
assessed to characterize the safety profile of the treatment regimens. Descriptive statistics denoting 
the changes from baseline to the final assessment visit with respect to key laboratory parameters and 
vital signs will also be provided.

Phase of Development: 2b 
 
Title of the Protocol:  
A Multicenter, Randomized, Open-Label Phase 2b Study to Investigate the Efficacy and Safety of 
Aldoxorubicin Compared to Topotecan in Subjects with Metastatic Small Cell Lung Cancer Who 
Either Relapsed or Were Refractory to Prior Chemotherapy 
Primary Objective: 
The primary objective of this study is to determine the efficacy of administration of aldoxorubicin 
compared to topotecan in subjects with metastatic small cell lung cancer (SCLC) who have relapsed 
or were refractory to prior chemotherapy, as measured by progression-free survival (PFS). 
Secondary Objectives: 
The secondary objectives of this study are to evaluate the efficacy of aldoxorubicin as measured by 
overall survival (OS), safety of aldoxorubicin compared to topotecan in this population assessed by 
the frequency and severity of adverse events (AEs), abnormal findings on physical examination, 
laboratory tests, vital signs, echocardiogram (ECHO) evaluations, electrocardiogram (ECG) results, 
and weight, as well as disease control rate and tumor response. 
Study Rationale and Significance: 
Aldoxorubicin (INNO-206; DOXO-EMCH) is a novel prodrug that binds covalently to albumin in the 
circulation. The drug is accumulated in tumors and doxorubicin is released in the tumor by cleaving 
the acid labile linker (EMCH) in the low pH tumor environment.  This carrier-linked prodrug has 
demonstrated enhanced antitumor activity with reduced toxicity in several murine models when 
compared with free doxorubicin. 
Patients with metastatic SCLC who have failed prior chemotherapies have a poor prognosis with 
response rates of <10-25%, PFS of around  2-4 months and median OS of approximately 6-10 
months, depending on the initial duration of response to first line treatment.  Several chemotherapy 
regimens have been explored as palliative therapy for subjects with these patients and include such 
agents as topotecan (only approved agent in the US), topotecan plus platinum, cyclophosphamide + 
doxorubicin + vincristine (CAV) and amirubicin (not approved in US). However, these regimens can 
be quite toxic and have not significantly impacted either PFS or OS in these individuals.  
Aldoxorubicin may improve upon the activity of these drugs without an increase in toxicity as has 
been demonstrated in animal studies.

Phase of Development: 2b 
 
Study Design and Methodology: 
This is a phase 2b open-label study evaluating the efficacy and safety of aldoxorubicin administered 
at 230 mg/m2 (170 mg/m2 doxorubicin equivalent) intravenously on Day 1 every 21 days compared to 
topotecan administered either IV at doses of 1.5 mg/m2/day for 5 consecutive days starting on Day 1, 
and repeated every 21 days, or 4 mg/m2 administered as a 30 min IV infusion on Days 1, 8 and 15 
every 28 days. Subjects will be randomized 1:1 to receive either aldoxorubicin or topotecan. 
Treatment with granulocyte colony-stimulating factor (G-CSF) should be administered to all subjects 
as per investigator’s clinical judgment or according to ASCO Guidelines (Appendix E).[31]  Note:  
aldoxorubicin, at higher doses, has been associated with >20% incidence of grade 3 or 4 
neutropenia.  
Subjects will visit the study site on Day 1 of each cycle. Safety monitoring, including AEs, a directed 
physical examination, laboratory evaluations (serum chemistry and complete blood count [CBC]), vital 
signs, weight measurements, Eastern Cooperative Group performance status (ECOG PS) and ECGs 
will be performed on Day 1 of each cycle (for all subjects).  Subjects receiving aldoxorubicin will have 
blood drawn for serum electrolytes to evaluate the anion gap prior to each drug administration. They 
will have CBCs and serum chemistries on Day 15 (± 1 day) of each cycle as well. Cardiac function 
will also be followed periodically (per schedule of evaluations) with ECHO for subjects receiving 
aldoxorubicin. Treatment will continue until tumor progression is observed, subject asks to withdraw, 
or unacceptable toxicity occurs.  
Tumor response will be monitored at baseline, every 6 weeks (±5 days) from Cycle 1-Day 1 through 
week 36, and then every 12 weeks (±5 days) until disease progression using the Response 
Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.[22] Overall survival, PFS, and PFS at 4 and 
6 months will be evaluated. Objective response rate (ORR; complete response [CR] and partial 
response [PR]), disease control rate (ORR plus stable disease [SD] at 4 months) and quality of life 
(ECOG PS) will be assessed.

assessed to characterize the safety profile of the treatment regimens. Descriptive statistics denoting 
the changes from baseline to the final assessment visit with respect to key laboratory parameters and 
vital signs will also be provided.

Phase of Development: 2b 
 
Title of the Protocol:  
A Multicenter, Randomized, Open-Label Phase 2b Study to Investigate the Efficacy and Safety of 
Aldoxorubicin Compared to Topotecan in Subjects with Metastatic Small Cell Lung Cancer Who 
Either Relapsed or Were Refractory to Prior Chemotherapy 
Primary Objective: 
The primary objective of this study is to determine the efficacy of administration of aldoxorubicin 
compared to topotecan in subjects with metastatic small cell lung cancer (SCLC) who have relapsed 
or were refractory to prior chemotherapy, as measured by progression-free survival (PFS). 
Secondary Objectives: 
The secondary objectives of this study are to evaluate the efficacy of aldoxorubicin as measured by 
overall survival (OS), safety of aldoxorubicin compared to topotecan in this population assessed by 
the frequency and severity of adverse events (AEs), abnormal findings on physical examination, 
laboratory tests, vital signs, echocardiogram (ECHO) evaluations, electrocardiogram (ECG) results, 
and weight, as well as disease control rate and tumor response. 
Study Rationale and Significance: 
Aldoxorubicin (INNO-206; DOXO-EMCH) is a novel prodrug that binds covalently to albumin in the 
circulation. The drug is accumulated in tumors and doxorubicin is released in the tumor by cleaving 
the acid labile linker (EMCH) in the low pH tumor environment.  This carrier-linked prodrug has 
demonstrated enhanced antitumor activity with reduced toxicity in several murine models when 
compared with free doxorubicin. 
Patients with metastatic SCLC who have failed prior chemotherapies have a poor prognosis with 
response rates of <10-25%, PFS of around  2-4 months and median OS of approximately 6-10 
months, depending on the initial duration of response to first line treatment.  Several chemotherapy 
regimens have been explored as palliative therapy for subjects with these patients and include such 
agents as topotecan (only approved agent in the US), topotecan plus platinum, cyclophosphamide + 
doxorubicin + vincristine (CAV) and amirubicin (not approved in US). However, these regimens can 
be quite toxic and have not significantly impacted either PFS or OS in these individuals.  
Aldoxorubicin may improve upon the activity of these drugs without an increase in toxicity as has 
been demonstrated in animal studies.

Phase of Development: 2b 
 
Study Design and Methodology: 
This is a phase 2b open-label study evaluating the efficacy and safety of aldoxorubicin administered 
at 230 mg/m2 (170 mg/m2 doxorubicin equivalent) intravenously on Day 1 every 21 days compared to 
topotecan administered either IV at doses of 1.5 mg/m2/day for 5 consecutive days starting on Day 1, 
and repeated every 21 days, or 4 mg/m2 administered as a 30 min IV infusion on Days 1, 8 and 15 
every 28 days. Subjects will be randomized 1:1 to receive either aldoxorubicin or topotecan. 
Treatment with granulocyte colony-stimulating factor (G-CSF) should be administered to all subjects 
as per investigator’s clinical judgment or according to ASCO Guidelines (Appendix E).[31]  Note:  
aldoxorubicin, at higher doses, has been associated with >20% incidence of grade 3 or 4 
neutropenia.  
Subjects will visit the study site on Day 1 of each cycle. Safety monitoring, including AEs, a directed 
physical examination, laboratory evaluations (serum chemistry and complete blood count [CBC]), vital 
signs, weight measurements, Eastern Cooperative Group performance status (ECOG PS) and ECGs 
will be performed on Day 1 of each cycle (for all subjects).  Subjects receiving aldoxorubicin will have 
blood drawn for serum electrolytes to evaluate the anion gap prior to each drug administration. They 
will have CBCs and serum chemistries on Day 15 (± 1 day) of each cycle as well. Cardiac function 
will also be followed periodically (per schedule of evaluations) with ECHO for subjects receiving 
aldoxorubicin. Treatment will continue until tumor progression is observed, subject asks to withdraw, 
or unacceptable toxicity occurs.  
Tumor response will be monitored at baseline, every 6 weeks (± 5 days) from Cycle 1-Day 1 through 
week 36, and then every 12 weeks (± 5 days) until disease progression using the Response 
Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.[22] Overall survival, PFS, and PFS at 4 and 
6 months will be evaluated. Objective response rate (ORR; complete response [CR] and partial 
response [PR]), disease control rate (ORR plus stable disease [SD] at 4 months) and quality of life 
(ECOG PS) will be assessed.

Number of Subjects: 
Approximately 132 subjects with metastatic SCLC who have either not responded to or have 
progressed after treatment with no more than 1 prior systemic regimens will be randomized 1:1 
(aldoxorubicin:topotecan) at approximately 40 study centers in the US and Europe. The 
randomization will be stratified according to their initial PS (ECOG PS 0-1 vs 2), and whether they 
had relapsed < or > 90 days after completing their initial therapy. 
Test Product and Mode of Administration: 
Aldoxorubicin: Lyophilized powder in vials that contain 200 mg of aldoxorubicin reconstituted by 
adding a solution of 50% ethanol: 50% sterile water, administration completed within 2 hours (of 
being reconstituted) as an approximate 30 minute IV infusion in Lactated Ringer’s solution.  Total 
dose of 230 mg/m2 (170 mg/m2 doxorubicin equivalent). 
Topotecan:  
Topotecan for Injection is supplied as a sterile lyophilized, buffered, light yellow to greenish powder 
available in single-dose vials. Each vial contains topotecan hydrochloride equivalent to 4 mg of 
topotecan as free base. The reconstituted solution ranges in color from yellow to yellow-green and is 
intended for administration by intravenous infusion (IVI). Each topotecan 4-mg vial is reconstituted 
with 4 mL Sterile Water for Injection. Then the appropriate volume of the reconstituted solution is 
diluted in either 0.9% Sodium Chloride IVI or 5% Dextrose IVI prior to administration. Because the 
lyophilized dosage form contains no antibacterial preservative, the reconstituted product should be 
used immediately.  
Criteria for Evaluation: 
Efficacy: 
The following efficacy variables will be evaluated as noted: 
 PFS 
 PFS at 4 and 6 months 
 OS 
 Objective tumor response (RECIST 1.1 criteria)[22] 
 Disease control rate (ORR + SD at 4 months) 
 Investigator assessment as measured by ECOG PS

Safety: 
The following safety variables will be assessed over the duration of the study: 
 AEs 
 Ability to remain on assigned treatment (tolerability) 
 Clinical and laboratory data including physical examinations, vital signs, weight, ECHO 
evaluations, ECG results and laboratory test results 
 Use of concomitant medications 
Statistical Methods: 
In accordance with the intention-to-treat principle, all randomized subjects will be evaluated for 
efficacy. All subjects who receive at least 1 dose of study medication will be evaluated for safety.  
Efficacy:   
The primary analysis of PFS will be carried out when 110 PFS events have occurred, approximately 6 
months following the completion of enrollment of 132 subjects. Survival distributions will be estimated 
using the Kaplan-Meier method and the 2 groups will be compared using a two-sided, unstratified log 
rank test at the α=0.05 level of significance. 
Tumor response will be monitored at baseline, every 6 weeks (± 5 days) from Cycle 1-Day 1 through 
week 36, and then every 12 weeks (± 5 days) until disease progression. The percentage of subjects 
with CR or PR, or SD will be evaluated and the disease control rate (CR, PR and SD at 4 months) will 
be compared using Pearson’s chi-square test, or if 20% or more of the expected cell frequencies are 
less than 5, Fisher’s exact test. Investigator reported outcomes as assessed by the ECOG PS will be 
analyzed using analysis of covariance. 
Subjects in each group will be stratified according to their initial PS (ECOG PS 0-1 vs 2) and whether 
they had progressed in less than or greater than 90 days after their initial chemotherapy. 
Sample Size Justification: 
Power calculations and subject numbers were calculated based on the primary endpoint of PFS.  
Reviewing the literature for studies that have evaluated topotecan as treatment for patients that have 
relapsed or not responded to first line therapies, it is estimated that the median PFS for the topotecan 
group will be 3.5 months and that the median PFS for the aldoxorubicin group will be 6.5 months.  
Based on the use of a two-sided log rank test at the α=0.05 level of significance, a total of 110 PFS 
events will be required for 90% power to detect this difference.  Assuming an 18 month accrual period 
and a 6 month follow-up period after enrollment of the last subject, approximately 132 subjects will be 
needed to achieve the total of 110 PFS events. 
Safety:  
The safety data will be summarized by treatment group.  The treatment groups will be compared with 
respect to occurrence of each AE. Total number of AEs leading to withdrawal, and abnormal 
laboratory tests will be compared between groups using Fisher’s exact test. Adverse events, ability to 
remain on assigned treatment (tolerability), and abnormal findings on physical examinations, vital 
signs, weight, ECG results, laboratory test results, and use of concomitant medications, will be 
assessed to characterize the safety profile of the treatment regimens. Descriptive statistics denoting 
the changes from baseline to the final assessment visit with respect to key laboratory parameters and 
vital signs will also be provided.
