About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

RESECT Study

39

- Surgeonsrsquo blinded assessment of pre- and post-treatment CT scans of patients with previously unresectable colorectal cancer liver metastases treated in the SIRFLOX study present at 12th Annual European-African HPB meeting

- While resectability increased from baseline to follow-up in both the chemotherapy only arm and the chemotherapy + SIRT arm of the SIRFLOX study the increase was significantly more pronounced in patients receiving the combination treatment

- 381 of these were resectable on the basis of their liver CT scan at follow-up compared to 289 of the patients receiving chemotherapy only (plt00001)

Mechanisms of Actionbull TACEDEB Designed to

impede blood flow potentially resulting in PES

bull SIR-Spheres Y-90 resin microspheres Designed to travel deep into the tumor bed and deliver beta radiation directly to the tumor and not impede blood flow

Advantages over TACE in HCC

bull TACE well established by two 2002 studies for inoperable intermediate stage HCC

bull Exceeds TACE in TTP of disease

bull Better toxicity profile

bull Better post treatment quality of life

bull Effective with more advanced disease

bull May use in patients is PVT bull Relative contraindication in TACEbull Similar survival to sorafenib (13 vs 11mo) but up to half TARE

patients downstaged for transplant

bull May have survival benefit (39mo vs 31 mo in BCLC B and C patients)

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

About Yttrium 90 microspheres

bull Yttrium 90 is a pure beta emitter with a half life of 268 days or 642 hours

bull 94 of the radiation is decayed in 11 days

17

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

Rationale for SIRT

bull Preferential blood supply to tumorbull Parenchyma is 30 arterial and 70

portal supplybull Metastases are nearly 100 arterial

bull Preferential vasculaturebull Microvasculature of hepatic tumor is

3-200x more dense than surrounding normal parenchyma

bull CRC cells are radiosensitivebull Radiation works synergistically with

radiation-sensitizing chemotherapy drugs

bull Targeted to the tumorbull Allows treatment of multiple and

large tumors not amenable to external beam radiation therapy or ablation

18

Benefits of SIRT

bull Provide a localized radiation therapy delivering a dose of internal radiation up to 40x higher than conventional external beam therapy

bull Healthy liver tissue remain relatively unaffected2

bull 90 of patients experience ltGrade 3 adverse events

bull Outpatient Procedure

bull Typically involves two treatments over 6 weeks

bull Most patients return home 4-6 hours after the treatment

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

mCRC Liver Metastases and Mortality

bull Liver is the most common site of distant metastatic disease1-12

- 50 develop hepatic mets

- 10-25 considered resectable

bull Liver failure due to hepatic metastases is the most common cause of death among patients with mCRC13

bull Chemotherapy induced parenchymal damage also significantly contributes to liver failure1-12

Protecting healthy parenchyma while effectively treating liver metastases is a key goal when treating

patients with liver dominant metastases

- Surgeonsrsquo blinded assessment of pre- and post-treatment CT scans of patients with previously unresectable colorectal cancer liver metastases treated in the SIRFLOX study present at 12th Annual European-African HPB meeting

- While resectability increased from baseline to follow-up in both the chemotherapy only arm and the chemotherapy + SIRT arm of the SIRFLOX study the increase was significantly more pronounced in patients receiving the combination treatment

- 381 of these were resectable on the basis of their liver CT scan at follow-up compared to 289 of the patients receiving chemotherapy only (plt00001)

bull Randomized controlled trial radioembolization as an adjuvant to first-line chemotherapy for metastatic CRC was examined

bull Chemotherapy-naive patients with liver-dominant colorectal liver metastases (530 patients) were randomized to a group receiving FOLFOX with or without bevacizumab and a group receiving FOLFOX with or without bevacizumab and radioembolization

bull There was an 8-mo increase in liver-progressionndashfree survival in the radioembolization arm (21 vs 13 mo)

bull However there was no difference in overall progression-free survival

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

RESECT Study

39

- Surgeonsrsquo blinded assessment of pre- and post-treatment CT scans of patients with previously unresectable colorectal cancer liver metastases treated in the SIRFLOX study present at 12th Annual European-African HPB meeting

- While resectability increased from baseline to follow-up in both the chemotherapy only arm and the chemotherapy + SIRT arm of the SIRFLOX study the increase was significantly more pronounced in patients receiving the combination treatment

- 381 of these were resectable on the basis of their liver CT scan at follow-up compared to 289 of the patients receiving chemotherapy only (plt00001)

bull Retrospective study 2017 ASO

bull 100 Patients who had SIRT with resin microspheres from 16 centers

bull 71 had resection 29 Liver transplant

bull Grade 3 + adverse complications and any grade liver failure in 24 resection group and 7 transplant group

bull 63 occurred in extended resection group (gt5 segments)

bull 125-23 grade 3 complications in non-SIRT patients

SIR-Spheres Y-90 resin microspheres Vs TACEDEB

41

Mechanisms of Actionbull TACEDEB Designed to

impede blood flow potentially resulting in PES

bull SIR-Spheres Y-90 resin microspheres Designed to travel deep into the tumor bed and deliver beta radiation directly to the tumor and not impede blood flow

Advantages over TACE in HCC

bull TACE well established by two 2002 studies for inoperable intermediate stage HCC

bull Exceeds TACE in TTP of disease

bull Better toxicity profile

bull Better post treatment quality of life

bull Effective with more advanced disease

bull May use in patients is PVT bull Relative contraindication in TACEbull Similar survival to sorafenib (13 vs 11mo) but up to half TARE

patients downstaged for transplant

bull May have survival benefit (39mo vs 31 mo in BCLC B and C patients)

Treatment Data on SIR-Spheresreg Y-90 Resin Microspheres for Patients with Liver Metastases from Right-Sided Primary Colon Cancer

A post-hoc analysis of data from the 739-patient SIRFLOX and FOXFIRE Global studies indicates that adding SIRT with liver-directed SIR-Spheresreg Y-90 resin microspheres to standard first-line mFOLFOX6 chemotherapy for liver-only or liver-dominant metastatic colorectal cancer (mCRC) in patients with right-sided primary (RSP) tumours led to a statistically significant and clinically meaningful 49-month median overall survival benefit (Hazard Ratio [HR] 064 [95 CI 046-089] p=0007) This translates into a 36 reduction in the risk of death at any given time compared to patients who received chemotherapy alone[1]

RESECT Study

39

- Surgeonsrsquo blinded assessment of pre- and post-treatment CT scans of patients with previously unresectable colorectal cancer liver metastases treated in the SIRFLOX study present at 12th Annual European-African HPB meeting

- While resectability increased from baseline to follow-up in both the chemotherapy only arm and the chemotherapy + SIRT arm of the SIRFLOX study the increase was significantly more pronounced in patients receiving the combination treatment

- 381 of these were resectable on the basis of their liver CT scan at follow-up compared to 289 of the patients receiving chemotherapy only (plt00001)

bull Retrospective study 2017 ASO

bull 100 Patients who had SIRT with resin microspheres from 16 centers

bull 71 had resection 29 Liver transplant

bull Grade 3 + adverse complications and any grade liver failure in 24 resection group and 7 transplant group

bull 63 occurred in extended resection group (gt5 segments)

bull 125-23 grade 3 complications in non-SIRT patients

bull 4 Deaths gt 6 segments resected multiple comorbidities

bull Study concludes mortality rates complication rates and LF rates

Is it Safe

SIR-Spheres Y-90 resin microspheres Vs TACEDEB

41

Mechanisms of Actionbull TACEDEB Designed to

impede blood flow potentially resulting in PES

bull SIR-Spheres Y-90 resin microspheres Designed to travel deep into the tumor bed and deliver beta radiation directly to the tumor and not impede blood flow

Advantages over TACE in HCC

bull TACE well established by two 2002 studies for inoperable intermediate stage HCC

bull Exceeds TACE in TTP of disease

bull Better toxicity profile

bull Better post treatment quality of life

bull Effective with more advanced disease

bull May use in patients is PVT bull Relative contraindication in TACEbull Similar survival to sorafenib (13 vs 11mo) but up to half TARE

patients downstaged for transplant

bull May have survival benefit (39mo vs 31 mo in BCLC B and C patients)

bull Retrospective
