ThermoGenesis ($KOOL) now in CLI ! (video)

ThermoGenesis Corp (NASDAQ: KOOL) press released an update on their Res-Q clinical evaluations:

ThermoGenesis Provides Update on Res-Q® Clinical Evaluations at Leading Stem Cell Therapy Conference

INITIAL DATA SHOW POSITIVE OUTCOMES IN TREATING CRITICAL LIMB ISCHEMIA AND LONG BONE FRACTURES

What is Res-Q ?  This is a point-of-care system designed for the preparation of cell concentrates, including stem cells, from bone marrow aspirates and whole blood for platelet rich plasma (PRP). The product is being tested in India in a trial co-sponsored by ThermoGenesis and Totipotent SC, the company's distributor for the Res-Q in India.

The trial has evaluated n=10 of n=15 planned patients with advanced CLI. Safety and AFS (limb salvage) at one year are being evaluated. Secondary endpoints such as ABI (ankle brachial index), six minute walk test, and resting pain are showing good results.

In addition a second trial is evaluating n=16 of n=20 patients with non-union or delayed union fracture of a long bone (tibia) who have undergone composite grafting with autologous bone marrow cell concentrate to evaluate the procedure's safety and effect on fracture healing. Long bone fractures represent an unmet medical need that the med tech companies have been chasing for years. So far the system has shown no intra-operative complications, and one non-device related adverse event. Of nine patients who are now out three-to-six months post-treatment, four have fractures that have united and four have experienced partial unions of the bone fracture which is quite hopeful.

Daily Dose Conclusion: Few are paying attention to KOOL as a therapeutic player in CLI or bone fractures and as a potential challenger to Cytori or even Aastrom or Pluristem in CLI. This is worth watching.

Celladon is focused in Heart Failure...gets Fast Track Designation (private)

Cell Therapy fan's know that on the Regenerative Medicine front the next major breakthrough may very well be in cardiovascular medicine. Several companies are in trials now with a wide range of cell therapies to stabilize failing hearts. What caught our eye today is news that private biotech company Celladon received fast track designation for Mydicar.

Celladon's MYDICAR® is a genetically targeted enzyme replacement therapy that is designed to restore functional levels of "SERCA2a", (a regulator of calcium cycling and contractility). In other words, this enzyme is required for the heart to beat properly and in patients whose heart is failing leading the enzyme levels to decline. MYDICAR® is a gene that is delivered using a recombinant adeno-associated virus (AAV) as the vector. This is really high tech gene therapy at a cellular level.

So what does this have to do with regenerative cell therapy ?

The phase 2 trial results (previously announced) showed the therapy met its primary safety and efficacy endpoints at 6 months for high dose MYDICAR® versus placebo. Additionally, 12 months after receiving a single infusion of MYDICAR®, patients treated with the highest dose versus placebo had an 88% risk reduction (Hazard Ratio = 0.12, P=0.003) of major cardiovascular events such as death, or a need for a left ventricular assist device (LVAD), cardiac transplant, or episodes of worsening heart failure and the related heart failure hospitalizations.

So now we are starting to see cardiac trials with therapies that are reporting a preservation of heart function and risk reduction as the therapeutic goals. We believe that in the cell therapy space, we will see a host of therapies developed along these same lines. We would take note on the autologous side of Baxter (P3) trial, NeoStem (NBS) (P2) trial, Aastrom (P2) and on the allogeneic side, MesoBlast (MSB), Cytori (CYTX), Athersys (ATHX), and others.

Critical Limb Ischemia (CLI) gets a lot of attention with Aastrom (ASTM), PluriStem (PSTI) and Aldagen (private) all talking about the potential but investors have not been convinced. We would watch closely the developments on the cardiac side as the unmet medical need here remains large. 

Why? The historical data sets and trial designs are well understood, so the feasibility of a successful trial based on what's known about the space is positive. News like Celladon, and a close examination of the trial goals bode well for the space.
