Individual Patient Expanded Access IND of Autologous HB-adMSCS for the Treatment of Bilateral Knee Pain.

• Screening Visit Week 0 The subject will go through a screening process that will last up to 14 days. During this time the Clinical Investigator will review labs and diagnostic test results to confirm study eligibility. Abnormal test results (i.e., ongoing infection), may require follow-up before proceeding with the treatment. This screening period will start with the "Screening Visit", which will include the following procedures:

1. Informed Consent will be obtained.
2. Demographics
3. Review of inclusion and exclusion criteria
4. Review of medical history and concomitant medications
5. Physical exam
6. Vital signs (Heart Rate, Blood Pressure, Respirations, Temp., SpO2)
7. Height and weight
8. Blood samples will be collected for safety assessments:
9. Hematology
10. Chemistry
11. Coagulation Panel
12. A verification of patient consent will be verbally performed.

• Intervention 1 Day 1 (Week 1) and Intervention 2 Day 1 (Week 12) Once the eligibility is confirmed, +7 days after the screening visit, the subject will return to

HBSCRF to receive the IV treatment. Procedures will be assessed as follows:

1. Review of medical history, adverse events, and concomitant medications.
2. Physical exam
3. Patient pain assessment VAS of Pain
4. Patient pain assessment WOMAC Knee Score
5. Vital signs (Heart Rate, Blood Pressure, Respirations, Temp., SpO2)
6. Weight measurement
7. A verification of patient consent will be verbally performed
8. The HB-adMSCs will be administered and the patient closely observed:
9. One intravenous infusion of HB-adMSCs (2x108 cells) to last 1 hour:
10. Volume: 250 ml
11. Rate: 4-5 mls/min (250ml/h)
12. The subject will then be monitored for a minimum of 1hr after infusion as follows:
13. Measure Vital signs at minute 0 of the infusion
14. Measure Vital signs at minute 15 after IV infusion.
15. Measure Vital Signs at minute 30 after IV infusion.
16. Measure Vital signs at minute 60 after IV infusion.
17. Measure Vital signs at minute 120 after IV infusion.
18. Vital signs will be recorded more frequently if clinically indicated).
19. The Subject will be given comprehensive discharge criteria/instructions.
20. Telephone encounter for adverse events. The subject will be contacted by telephone the following day after the infusion visit to determine if any adverse events have occurred.

• Post infusion discharge criteria Immediately following the completion of each infusion/injection, the subject should be assessed to ensure that the post-infusion discharge criteria have been met. Parameter Values Systolic blood pressure + 20% of baseline. Diastolic blood pressure + 20% of baseline. Heart rate + 20% of baseline Temperature >96.7F and <100.5F Respiratory rate >10 breaths per minute and < 22 breaths per minute Pulse oximetry > 94% on room air Additionally, the following will be documented to ensure a safe discharge from the research facility:
• The patient must be alert and oriented with normal mentation status.
• The patient must be afebrile with vital signs within normal limits.
• The patient will be able to ambulate with little or minimal assistance.
• The patient will rate a level of pain at 3 or below on a scale of 0-10.
• Intervention 1 Day 2 (Week 1) and Intervention 2 Day 2 (Week 12) 24 hours after the IV infusion the subject will go to the PI's clinic office to receive the intra- articular injections.

1. Review of medical history, adverse events, and concomitant medications. b. Vital signs (Heart Rate, Blood Pressure, Respirations, Temp., SpO2) c. Knee MRI without contrast at IA injection 1. If a Knee MRI without contrast has been performed in the last 14 days, it can be used as a baseline and compared with the following Knee MRI without contrast.
2. The HB-adMSCs will be administered and the patient closely observed:
3. One ultrasound-guided intra-articular injection in the right knee with 1x108 cells/2ml.
4. One ultrasound-guided intra-articular injection in the left knee with 1x108 cells/2ml.
5. The subject will then be monitored for a minimum of 30 minutes after the injections as follows:
6. Measure Vital signs at minute 0 of infusion. b. Measure Vital signs at minute 15 after IV infusion. c. Measure Vital Signs at minute 30 after IV infusion. d. (Vital signs will be recorded more frequently if clinically indicated). f. The Subject will be given comprehensive discharge criteria/instructions. g. Blood samples will be collected for safety assessments:
7. Hematology b. Chemistry c. Coagulation Panel h. Telephone encounter for adverse events. i. The subject will be contacted by telephone the following day after the infusion visit to determine if any adverse events have occurred.

• Post injection discharge criteria Immediately following the completion of each infusion/injection, the subject should be assessed to ensure that the post-infusion discharge criteria have been met. Parameter Values Systolic blood pressure + 20% of baseline. Diastolic blood pressure + 20% of baseline. Heart rate + 20% of baseline Temperature >96.7F and <100.5F Respiratory rate >10 breaths per minute and < 22 breaths per minute Pulse oximetry > 94% on room air Additionally, the following will be documented to ensure a safe discharge from the research facility: • The patient must be alert and oriented with normal mentation status. • The patient must be afebrile with vital signs within normal limits.
• The patient will be able to ambulate with little or minimal assistance.
• The patient will rate a level of pain at 3 or below on a scale of 0-10. -Weeks 3 and 14 - Follow Up Visits The patient will be assessed for adverse events 24 hours after each injection with a follow up phone call. The patient will also undergo a thorough on-site follow up visit at the infusion site (HBSCRF) that will include:
