EXHIBIT B: ‘THE PROPOSAL’

THE ROLE OF SPHINGOLIPIDS IN HUMAN DISEASE

RESEARCH PLAN PROJECT I: The Role of Sphingolipids in Cardiac Ischemia

A. SPECIFIC AIMS

The identification of signaling components involved in cardiac ischemia reperfusion (IR) injury is a critical step toward discovering therapeutic interventions for reducing the size of cardiac infarcts and improving patient outcomes. Research has demonstrated sphingolipid signaling molecules are key components that participate in the cell death and loss of function associated with cardiac IR injury, and furthermore, that induction of this pathway is one of the earliest events during this process. Preliminary studies in our laboratory have suggested that activation of the sphingolipid-signaling pathway by IR occurs through the neutral form of sphingomyelinase (nSMase1) and its adaptor protein, FAN (factor associated with neutral SMase activation).

With this in mind, we have the following project goal: The development of a small molecule inhibitor of the sphingomyelinase signaling system that will provide protection from cardiac cell death and loss of inotropy during acute ischemic insults such as during an acute myocardial infarction (AMI).

• PHASE I: Validation of FAN and nSMase1 as targets for therapeutics intervention. This validation is required before embarking on a drug discovery program (Phase II).

• PHASE II: Demonstration in pre-clinical trials that drug candidates against nSMase1 and/or FAN are effective in preventing cardiac cell death and loss of inotropy associated with IR injury.

The proposed Phase I research plan will include preliminary studies that reveal, for the first time, that FAN is a critical mediator in the cardiomyocyte cell death process induced by IR. These studies will additionally provide evidence that nSMasel is the specific isoform of nSMase involved in this process.

Accordingly, the Phase I validation of nSMase1 and FAN as targets for therapeutic intervention will include the following specific aims:

• Specific aim 1: Determine whether infarct sizes are reduced and left ventricular pressure improved after an acute ischemic event in the absence of the FAN/nSMase signaling system by producing reversible cardiac infarcts using our in-house FAN knockout mouse model.

• Milestone 1: Completion of surgeries and measurements of infarct size and left ventricular developed pressure (LVDP). Expectation of 20 – 50% decrease in infarct size and significant increase in LVDP.

• Specific aim 2: Determine whether infarct sizes are reduced and left ventricular pressure improved after an acute ischemic event in the absence of the FAN/nSMase signaling system by producing reversible cardiac infarcts using a currently available nSMase1 knockout mouse model.

6

• Milestone 1: Establishment of breeding colony.

• Milestone 2: Completion of surgeries and measurements of infarct size and left ventricular developed pressure (LVDP). Expectation of 20 – 50% decrease in infarct size and a significant increase in LVDP.

The anticipated success of accomplishing these aims will demonstrate that the sphingomyelinase signaling system is a major participant in ischemia/reperfusion injury by validating nSMase1 and FAN as targets for drug discovery. This target validation will enable us to identifying small molecule inhibitors of this signaling system that can used in pre-clinical trials that we will propose in PHASE II. The ultimate goal of the research is to develop lead compounds that can be taken to Phase 1 Clinical Trials. The proposed work will form the basis of discovering novel medical therapeutics that will reduce the cell death associated with AMI and other acute ischemic events in the clinical setting.

RESEARCH PLAN PROJECT II: Sphingolipids as Markers of Cardiac Ischemia

A. SPECIFIC AIMS

The over all project goal is to develop a sphingolipid-based diagnostic for cardiac ischemia that can be used to evaluate patients suffering from acute cardiac ischemia.

PHASE I: Validation that sphingolipids are sensitive and specific markers of cardiac ischemia in a trial designed to provoke ischemia in stable angina patients. This validation is required before embarking on a chest pain Emergency Department trial (Phase II).

PHASE II: Conduct a follow-on clinical trial using sphingolipids as biomarkers for the evaluation of acute coronary syndrome (ACS) in the Emergency Department. Develop a simple antibody-based test platform that would be used in clinical laboratory instruments and point-of-care triage (POCT) determinations of cardiac ischemia.

It is now known that coronary artery disease is aggravated by inflammation. It has been suggested that sphingolipid signaling molecules are mediators of inflammation, particularly in response to pre-inflammatory cytokines such as TNFa and IL2. In addition to release by these molecules as part of the inflammatory response, sphingolipids are possibly produced as a direct result of ischemia. In this case, one may expect to observe increased sphingolipid production either as a consequence of the TNFa produced by ischemic cardiac tissue or directly from heart cells. It is also possible that the sphingolipids are responsible for the poor outcomes observed in acute coronary syndrome patients who have elevated serum levels of TNFa. Thus, we reasoned that sphingolipids produced either by inflammation or ischemia would correlate with coronary disease. Consequently, we initiated a clinical study designed to test the hypothesis that blood levels of key sphingolipids are predictive of obstructive CAD.  In an open trial of all patients sent to the catheterization lab for angiography, serum sphingosine-1-phosphate (S1P) was found to be a robust predictor of coronary disease. Subsequent subgroup analyses demonstrated that the predictive power of serum S1P was dramatically improved for patients hospitalized for evaluation of cardiac ischemia. Animal and cell culture experiments demonstrated that ischemic hearts produce significant amounts of sphingolipids and release it into the extracellular compartment. These recently published studies suggest that serum sphingolipids could be used

7

to predict cardiac ischemia independent of the inflammatory response. A clinical trial is required with clear ischemia endpoints to determine the predictive power of serum sphingolipids as ischemic markers.

Accordingly, we have designed a trial with the following PHASE I specific aims:

1) Conduct a clinical trial designed to provoke active ischemic in patients presenting with angina who undergo exercise treadmill testing (ETT). Serial blood samples will be obtained before and several times after treadmill testing for the determination of serum sphingolipid levels.

Milestone: Consent 200 patients into the trial

2) Compare serum sphingolipid levels with inflammatory biomarkers, CRP and TNFa, MI markers (TnI) and standard assessments of CHD, including stress ECG, stress echo, nuclear myocardial scanning and coronary angiography

Milestone 1: Establish the specificity and sensitivity of the putative ischemic markers with a yes/no evaluation of active ischemia

Milestone 2: Confirm yes/no for ischemia based on positive stress ECGs, stress echos and nuclear myocardial scans with CAD determined by coronary angiography. Ischemia-negative patients are those with a negative stress ECGs, stress echos and nuclear myocardial scans.

Milestone 3: Serum sphingolipids as putative ischemic markers should better correlate with clinicial endpoints than other serum analytes used in the study (inflammatory markers and TnI) in patents not experiencing MI

3) Develop monoclonal antibodies suitable for developing a serum assay for testing of patients suspected of cardiac ischemia

Milestone 1: Obtain stable hybridoma cell lines with high titers (>100,000 dilution)

Milestone 2: Purify antibodies and determine Kds for each hybridoma culture

The anticipated success of accomplishing these aims will demonstrate that serum sphingolipids are ischemic biomarkers that can form the basis of a simple blood test for ischemia that will be developed in PHASE II. Thus, the overall goal of this work is to develop a test for active ischemia suitable for clinical laboratory instruments and point-of-care triage (POCT) applications. This test could be used to improve the sensitivity and specificity of ETT and could be used as a point of care triage in the emergency department to demonstrate non-cardiac causes of chest pain. Patients presenting with potential cardiac complaints could be screened initially with sphingolipid analyte testing in addition to standard assays. A second use for sphingolipid ischemic markers may be as an additional component of risk stratification. Given that published work from our laboratory indicates that elevated serum S1P levels are independent of traditional factors, it may improve the accuracy of algorithms designed to identify patients who need more aggressive diagnostic evaluations or medical interventions (12).

The proposed studies will demonstrate for the first time that serum sphingolipids are powerful and novel markers of cardiac ischemia. Positive results from the proposed work will suggest additional clinical trials and laboratory investigations needed to elucidate the underlying mechanisms linking sphingolipids with ischemia and provide guidance on how sphingolipids can be best used to improve patient care and outcomes.

RESEARCH PLAN PROJECT III: Anti-sphingolipid Antibodies in the Treatment of Cancer

A. SPECIFIC AIMS

The identification of signaling components that promote tumor growth is a critical step toward discovering therapeutic interventions for reducing cancer’s morbidity and mortality and generally improving patient outcomes. Research has demonstrated that sphingosine kinase (SPHK) is a recently validated oncogene that produces an extracellular sphingolipid signaling molecule, sphingosine-1-phosphate (S1P), that promotes tumor growth. Tumor growth is promoted both directly and indirectly by S1P’s growth factor actions related to tumor cell proliferation and metastasis, as well as S1P’s pro-angiogenic effects. Medlyte has produced a biospecific monoclonal anti-S1P antibody (anti-S1P Mab) that could be used as a therapeutic molecular sponge to selectively absorb S1P, thus lowering extracellular concentrations of this tumor growth factor with the anticipated reduction in tumor volume and metastatic potential as well as simultaneously blocking new blood vessel formation that would, otherwise, feed the growing tumor. The anticipated success of the molecular absorption concept will represent an innovative approach to the treatment of cancer.

Accordingly in Phase I of the proposed work, our project goal is to evaluate the therapeutic potential of our anti-S1P monoclonal antibodies. In accomplishing this goal, we have the following Specific Aims:

• Specific Aim 1: In vitro testing of anti-S1P Mab’s ability to reduce S1P-dependent cell proliferation and metastatic potential.

• Milestone 1: Test ability of anti-S1P Mab to reduce S1P-dependent proliferation in selected tumor cell lines. Determine if Mab-reduced cell count is due to removal of S1P’s anti-apoptotic protective effects.

• Milestone 2: Test ability of anti-S1P Mab to reduce S1P-dependent cell migration in an in vitro Matrigel assay for metastatic potential.

• Milestone 3: Test ability of anti-S1P Mab to reduce S1P-dependent angiogenesis in an in vitro Matrigel angiogenesis assay using HUVECs.

• Specific Aim 2: In vivo testing of anti-S1P Mab’s ability to reduce tumor growth and associated angiogenesis.

• Milestone 1: Test Mab’s ability to reduce volume of Xenografted tumors in SCID mice.

• Milestone 2: Use Matrigel plugs implanted subcutaneously in C57B1/6N mice to test the anti-angiogenic effects of the anti-S1P Mab.

By successfully accomplishing these aims, we will demonstrate that Medlyte’s anti-S1P Mab is an effective therapeutic in the treatment of cancer in animal models. The anticipated success of the proposed initial pre-clinical work will lead to more intensive pre-clinical testing for safety and efficacy planned for Phase II. The ultimate goal of the Phase II research is to develop humanized anti-S1P Mabs that can be taken to Phase 1 Clinical Trials for comparison with the

9

anthracycline anti-neoplastic agents. Further, the anti-S1P Mab will be developed as an in vitro diagnostic tool to define the minimum dosage for optimum efficacy. While therapeutic antibodies are not generally regarded as toxic, the theranostics approach will improve patient safety in our planned clinical trials. Importantly, the pathway for getting our putative therapeutic antibody to market will be much shorter than the conventional small molecule approach.
