TEMPO1 COORDINATING CENTRE Issue1 Issue #2, Halloween 2013 NEWSLETTER TRIALS UPDATE: IN THIS ISSUE TIER 2 Now Open! DSMB The Data Safety Monitoring Board (DSMB) recently met on September 30, 2013, to review the first 25 subjects enrolled into Tier 1 (0.1mg/kg dose). The DSMB had no safety concerns; therefore they have agreed that the study continue with enrollment and can proceed to Tier 2 dosing (0.25mg/kg). The DSMB will review the data again after the next 10 subjects have been enrolled to assess safety in Tier 2. A total of 25 subjects will be enrolled into Tier 2. The first subject was enrolled into Tier 2 at the Calgary site last week. The subject had a Left M1 occlusion; the 48 hour CTA revealed recanalization of the artery. Subject was discharged home on Day 5 with a NIHSS of 0. STUDY DRUG Subjects will now be receiving a larger dose of TNKtPA in Tier 2; therefore it is no longer required to use a separate 3 cc syringe to draw up a small, exact amount of TNKtPA. You can now use the 10cc syringe provided in the TNKtPA kit to: 1) inject the sterile water into the TNKtPA, 2) draw up and 3) administer the drug all with the same syringe. AMENDMENT #2 We have revised the TEMPO1 protocol for clarity. There are no major changes in patient enrollment process or study design. Health Canada has approved Amendment #2, Protocol Version 2.2, dated Aug 28, 2013. We have clarified that: a) INR ≤ 1.4 is eligible; INR > 1.4 is excluded. b) Clinical eligibility does not mandate a current measurable deficit. NIHSS = 0 is not an exclusion. c) Exclusion #12: Stroke Thrombolysis Guidelines: Enrolment in TEMPO1 and treatment with TNKtPA may still be considered if there is reasonable clinical justification. We have clarified that these are relative guidelines and that if treatment is still considered safe, despite a relative contraindication, it must be justified clinically. REB approval must be obtained prior to enroling under Amendment #2. No changes are required to the Informed Consent form. The University of Calgary is the official sponsor for the TEMPO1 trial. We would like to thank Dr. Jennifer Mandzia for her contributions this past year working on the TEMPO1 trial as a stroke fellow. We wish Jen best wishes practicing in London, Ontario. We welcome Dr. Veronique Dubuc, from Montreal, Quebec, as our current TEMPO1 fellow. TEMPO-1 Update:

TIER 2 Now Open!

DSMB The  Data  Safety  Monitoring  Board  (DSMB)  recently  met  on  September  30,  2013,  to  review  the  first  25  subjects  enrolled  into  Tier  1  (0.1mg/kg  dose).    The  DSMB  had  no  safety  concerns;  therefore  they  have  agreed  that  the  study  continue  with  enrollment  and  can  proceed  to  Tier  2  dosing  (0.25mg/kg).    The  DSMB  will  review  the  data  again  after  the  next  10  subjects  have  been  enrolled  to  assess  safety  in  Tier  2.    A  total  of  25  subjects  will  be  enrolled  into  Tier  2.      

The  first  subject  was  enrolled  into  Tier  2  at  the  Calgary  site  last  week.    The  subject  had  a  Left  M1  occlusion;  the  4-­‐8  hour  CTA  revealed  recanalization  of  the  artery.    Subject  was  discharged  home  on  Day  5  with  a  NIHSS  of  0.      

STUDY DRUG Subjects  will  now  be  receiving  a  larger  dose  of  TNK-­‐tPA  in  Tier  2;  therefore  it  is  no  longer  required  to  use  a  separate  3  cc  syringe  to  draw  up  a  small,  exact  amount  of  TNK-­‐tPA.    You  can  now  use  the  10cc  syringe  provided  in  the  TNK-­‐tPA  kit  to:  1)  inject  the  sterile  water  into  the  TNK-­‐tPA,  2)  draw  up  and  3)  administer  the  drug  all  with  the  same  syringe.        

AMENDMENT #2 We  have  revised  the  TEMPO-­‐1  protocol  for  clarity.    There  are  no  major  changes  in  patient  enrollment  process  or  study  design.  Health  Canada  has  approved  Amendment  #2,  Protocol  Version  2.2,  dated  Aug  28,  2013.      

We  have  clarified  that:    

a)  INR  ≤  1.4  is  eligible;      INR  >  1.4  is  excluded.        

b)  Clinical  eligibility  does  not  mandate  a  current  measurable  deficit.    NIHSS  =  0  is  not  an  exclusion.  

c)  Exclusion  #12:  Stroke  Thrombolysis  Guidelines:    Enrolment  in  TEMPO-­‐1  and  treatment  with  TNK-­‐tPA  may  still  be  considered  if  there  is  reasonable  clinical  justification.  We  have  clarified  that  these  are  relative  guidelines  and  that  if  treatment  is  still  considered  safe,  despite  a  relative  contraindication,  it  must  be  justified  clinically.      

REB  approval  must  be  obtained  prior  to  enroling  under  Amendment  #2.  No  changes  are  required  to  the  Informed  Consent  form.

The TEMPO-1 Executive Committee, July 2013, our last meeting with Jen.

Frequently  Asked  Questions:  

 

Is  it  a  Protocol  Deviation  if  the  ECG  is  performed  after  the  tNK  has  been  administered?    

No,  you  have  6  hours  from  subject  enrolment  to  have  an  ECG  performed.    Please  have  the  treating  Investigator  review  it,  sign  and  date  it  promptly.  

Can  you  repeat  the  baseline  CTA  if  the  90  minute  window  has  expired  to  restart  the  clock?  

Yes,  if  the  subject’s  Creatinine  level  is  normal  and  an  occlusion  is  seen  on  the  first  CTA.    The  second  CTA  time  will  be  used  for  patient  enrolment.    It  may  be  suggested  that  a  MRA  be  performed  at  the  4-­‐8  hour  follow-­‐up  to  reduce  renal  contrast  overload.  

What  hemorrhage  rate  is  being  quoted  in  Tier  2  when  enroling  a  subject  and  obtaining  informed  consent?    

1-­‐2%.
