1. OBJECTIVE/LAY SUMMARY: The objective of this study is to evaluate the toxicity that may occur during a 3-28 day post-dosing period following the acute administration of FGF-1 directly into the ischemic heart of a dog.

 

2. REGULATORY REFERENCE: This study will be performed under Good Laboratory Practice Regulations; The Standard Operating Procedures of the test facility will be followed, and all appropriate study documentation’s will be maintained in the study file.

 

3. STUDY DESIGN: During the ischemic insult and dose administration procedure the following values will be obtained every 10-15 minutes: electrocardiograms (ECG’s), heart rate (HR), systolic arterial pressure(SAP), diastolic arterial pressure(DAP), and mean arterial pressure(MAP) will be monitored and recorded. BP and ECG changes occur during ischemic insult, or any time thereafter including dose administration, values will be monitored until baseline values are established, but not to exceed 30 minutes post. A printout of ECG’s will be performed when values change and every 10-15 minutes, thereafter.

 

The following groups of animals will be used on study:

 

Group 1

   Vehicle    5 dogs (3 male and 2 female)    28 day post-dosing necropsy

Group 2

   0.02 mg/kg FGF    5 dogs (3 male and 2 female)    28 day post-dosing necropsy

Group 3

   0.2 mg/kg FGF    5 dogs (3 male and 2 female)    28 day post-dosing necropsy

Group 4

   Vehicle    3 dogs (2 male and 1 female)    3 day post-dosing necropsy

Group 5

   0.2 mg/kg FGF    3 dogs (2 male and 1 female)    3 day post-dosing necropsy

 

Treatment Regimen:

 

Each dog will receive an ischemic insult to the heart, using a balloon-tipped catheter, where injury and thrombus formation are directed at the left circumflex coronary artery. The ischemic insult will be monitored angiographically and by electrocardiograms. The animals will have a 7 day recovery period prior to dosing with the test article or vehicle. The total dosage is given. Each animal will receive two injections of FGF-1, one injection in the general area of the ischemic insult and one injection in healthy heart tissue. Group 2 will receive two injections of 0.02 mg/kg FGF-1 and group 3, two injections of 0.2 mg/kg FGF-1. The injections of the vehicle or test article will be made directly into the cardio-ventricular wall via a mini-thoracotomy. The volume of each injection will be 0.25 ml and will contain the growth factor and heparin in a physiologic saline solution. The amount of heparin in each injection will at a fixed ratio of 1000 IU heparin/mg FGF-1, the same as will be used in the proposed clinical trial. The Sponsor will include the heparin in each dose and in the vehicle. Both the high and low dose of heparin will be represented in the vehicle groups.

 

Cardiovascular Measurements:

 

1. Angiograms: A total of 4 angiograms will be performed on each dog including a base-line angiogram, one after the ischemic insult, one after dosing of vehicle or test substance and one prior to necropsy.

A. Animal Husbandry and Maintenance: Animals will be individually housed during the test period. During the holding and testing period husbandry maintenance and environmental conditions will be maintained as in the quarantine period, unless changes are needed which will be noted in the protocol.

 

B. Environmental Conditions: The conditions in the room will be maintained as follows: room temperature will be maintained 64-84deg F and the humidity will range 30-70%, and the room will have 12/12 light/dark cycle.

 

C. Water: Tap water will be provided to the animals ad libitum (unless the animal is being fasted. Water analysis will be performed biannually and made available for the study file. Water will be analyzed by an independent contract facility. The results will include the following: heavy metals, chlorinated hydrocarbons, organophosphates, nitrates, nitrites, total trihalomethanes, dissolved minerals, and a standard plate count.

 

D. Diet: LabChows, Lab Diet Certified Canine Chow Brand will be fed to the animal daily. The lot and expiration will be documented and recorded on file. Chow may differ if specified by sponsor.

 

6. TECHNICAL PROCEDURES: The procedures described will be performed in accordance will the Standard Operating Procedures of DaVinci Biomedical Research Prod. Data collected will be documented manually.

 

A. Body Weights: Individual body weights will be recorded prior to surgery on the surgery form and prior to necropsy.

 

B. Fasting of Animals: All animals will be fasted at least 12-24 hours prior to surgery((NPO) no food or water).

 

C. Preoperative Procedure:

 

Anesthesia: Each animal will be anesthetized with butorphenol (0.2 mg/kg), acepromazine (0.l mg/kg), and atropine (0.02 mg/kg) IM as a pre-medicated cocktail and then Propofol will be administered at 4 mg/kg IV for anesthesia at a rate of 1 ml/10kg/min prior to surgery preparation. The animal will be immediately intubated and maintained under anesthesia with inhalant isoflurane anesthetic at 2.5%-4% for induction and 0.5-2.5% for maintenance delivered through either a volume-regulated respirator or rebreathing apparatus. An intravenous catheter will be placed in a peripheral vessel for

drug administration if needed, and Lactated Ringer solution to be administered at l0ml/kg/hr. If emergency drugs are needed they will be administered through this line and the drug, dose, route, and site of administration will be documented in the surgical file.

 

Surgical Preparation: The animal will be clipped over the femoral artery and will be positioned supine. The operative area will be cleaned with a three alternating scrubs of povidone-iodine scrub and 70% alcohol, once the alternating scrubs are done a final application of povidone-iodine solution will be applied and allowed to dry. (the area will be draped for aseptic surgery).

 

D-1. Surgical Procedure:

Induced myocardial ischemia: Once the surgical site has been aseptically draped and is prepared for surgery a Slazenger needle will be used to make an arteriotomy into the femoral artery, upon successful insertion into the artery a guide wire will be introduced through the needle into the artery, the needle will be removed and the introducer will be placed over the guide wire into the artery. With the use of an Angio-catheter and fluoroscopic guidance the catheter will be advanced up and over the aortic arch and into the ostia and placement will be confirmed by coronary arteriogram with contrast media (MD-76, Mallinkrodt Medical) of the left coronary artery. A guide-wire will be used to advance into the circumflex artery and an appropriate sized balloon will be used to advance over the guidewire to the position of choice. The balloon will be expanded and the intimal layer of the artery will be injured, this will be performed by push-pull mechanism. Post injury the balloon will be deflated and withdrawn from the injury site, and will be inflated distally to acquire stasis. Occlusion will occur quickly and a pre and post ischemic image will be taken.

 

  E. Postoperative Procedures: Post surgery the surgical sites will be monitored and checked once daily for any evidence of infection, bleeding dehiscence, or swelling.

 

  1) Recovery: The animal will be allowed to recover from anesthesia, and the animal will be extubated when the swallowing reflex has returned.

 

  2) Postoperative Analgesia: If needed post ischemia insult analgesia will be given. Analgesia will be given post dose administration. In addition to the preoperative administration of Butorphenol (0.2 mg/kg,IM), a 3 day post surgery regimen of Buprenorphine @0.02 mg/kg BID SC will be given. In some cases additional doses may be needed at the discretion of the facility veterinarian.

 

D-2. Route and Rationale of Test Article Administration:

The route of administration of the FGF-1 will be by two direct injections into the cardio-ventricular wall; one injection will be administered in 0.25 ml of a heparin/saline solution in the general area of the heart that has suffered an ischemic injury. The second injection of 0.25 ml will be in healthy heart tissue. The site of both injections will be marked with a suture. This route of administration was selected because the test article is intended to be

injected directly into the heart of human patients in order to stimulate new blood vessel formation.

 

F. Follow-up Dose Administration:

 

Approximately seven days after ischemic insult, the animal will be Anesthetized in accordance to section 6. C, and either femoral site, and left lateral rib cage will be clipped and prepped for aseptic surgery. Upon surgical preparation and aseptic draping of the animal, an introducer and guide catheter will be placed as in the initial surgery, a angiogram will be taken of the circumflex artery. Upon completion of the angiogram a thoracotomy will be made between the 4-5 intercostal space to expose the pericardium (prior to thoracotomy bupivacaine will be administered IM intercostal at a dose of 2mg/kg). The pericardium will be incised and 2-0 suture will be used to harness and elevate heart. The area of insult will be located and the test article or vehicle dose will be administered by needle puncture into the myocardium. A thoracic catheter will be placed and the intercostal space will be closed with 2-0 non absorbable suture. The catheter will be exteriorized from a separate intercostal space to the subcutaneous space and the air from the thoracic cavity will be removed using a 60cc syringe. Upon removal of all air the catheter will be removed and the exit site will be closed.

 

G. Post operative Observations: Post surgery the animal will be observed once daily for 3-5days for any abnormalities. The animal will be observed for any abnormalities in: skin, hair, respiratory, lethargy, fecal output, food consumption, dehiscence of surgical sites, edema, infection, and vocalization. All observations will be documented in the study file. If abnormal observations are evident the study director or the attending veterinarian will be notified immediately.

 

H. Animals Found Dead or Moribund: Any animals found with life threatening signs which would indicate that they would not survive until the next observation day will be immediately reported to the study director or the attending veterinarian. The time of death if applicable will be documented appropriately, and a full necropsy will be performed to evaluate the cause of death.

 

7. Animal Observations:

 

  1) Cageside observations: Cageside observations will be performed twice daily for mortality and moribundity.

 

  2) Monitoring Procedures:

 

a). Electrocardiogram: Electrocardiogram (ECG) tracings (lead II) will be obtained using the Datascope Passport II.

 

b). Direct Blood Pressure and Heart Rate: Heart rate, and direct blood pressure parameters for MAP, SAP, and DAP will be monitored on day -7 pre and post ischemia formation on day 0 pre and post treatment, and at necropsy pre euthanasia.

8. SAMPLE COLLECTION:

 

  A. Blood Collection: Blood samples for PK measurements and cardiac enzyme determinations will be collected, processed for serum, aliquotted, and placed on wet or dry ice for shipment to the appropriate lab for analysis. PK samples will be sent to the Sponsor, and cardiac enzyme samples will be sent to Analytics Lab, 200 Girard St, Suite 200, Gaithersburg MD 20877. CPK samples will be frozen prior to shipment, and LDH samples will be shipped on wet ice. The Sponsor will be notified before any samples are shipped to verify the number of samples to be analyzed.

 

9. NECROPSY:

 

  A. Euthanasia: All dogs euthanized in extremis or surviving until the scheduled necropsy will be anesthetized by an intravenous injection of sodium pentobarbital and exsanguinated.

 

  B. Macroscopic Examination: A complete necropsy will be conducted on all animals (whether dying spontaneously or euthanized, in extremis or at the scheduled necropsy). Animals in Groups 4 and 5 will be necropsied on Day 3, while animals in Groups 1,2, and 3 will be necropsied on Day 28. The necropsy will include examination of the external surface, all orifices, and the oral, cranial, thoracic, abdominal and pelvic cavities, including contents. The entire epicardial surface of the heart will be examined before opening. Any noticeable gross lesion will be documented. The heart will be opened along the path of normal blood flow (along the length of each ventricle at the midpoint of each ventricular free wall [right and left]), and through the left and right AV valves into the atria, avoiding any gross lesions. The entire endocardial surface will be examined. The heart will be fixed in toto in 10% neutral buffered formalin. In addition, highly perfused organs (e.g., lung, liver, kidneys) will be removed and fixed in formalin. Any eyes showing signs of abnormal angiogenesis on ophthalmic exam will be removed and fixed.

 

  C. Microscopic Examination: The fixed heart will be shipped to Mass Histology Service, Worcester, Massachusetts, for preparation and evaluation. Microscopic examination of hematoxylin and eosin (H & E) stained paraffin sections and/or T.T.C stained sections will be performed on the heart tissue. The heart will be sectioned at trimming. Approximately 6 sections from the ischemic ventricular wall area and 6 sections from the non-ischemic ventricle wall area will be obtained. In addition, approximately 2 sections from the interventricular septum will be obtained, as well as 1 or 2 sections of each atrium. The site of each injection of the test substance or vehicle, marked by sutures, will be examined. In addition, an examination to determine whether new blood vessels have formed in the area of test substance injection will be conducted, if feasible.

 

10. VETERINARY SUPPORT: The procedures described below will be performed in accordance with the Test Facility’s Standard Operating procedures.

 

  A. Concurrent Therapy: In accordance with accepted veterinary practice, the animals may be administered treatment of minor infections, fluid therapy, pain relief, antibiotic therapy, and any other therapy for which necessity may become evident in the course of
