Introduction: Scleroderma or systemic sclerosis (SSc) is an autoimmune, multi-organ connective tissue disease characterized by vascular dysfunction and increased fibroblast activity resulting in fibrosis of the skin, heart, lungs, and ultimately internal organ failure leading to death (1), with an estimated prevalence of SSc in the United States to be around 240 cases per 1 million adults (2). SSc is a complex, heterogeneous disease with clinical forms ranging from limited skin involvement (limited cutaneous systemic sclerosis) to forms with diffuse skin sclerosis and severe and often progressive internal organ involvement (diffuse cutaneous SSc (3)). Pulmonary fibrosis and interstitial lung diseases (ILD) occur in about 60% of patients contributing to mortality (4), while dermal fibrosis causes significant morbidity in scleroderma (5, 6). The etiology of SSc is unknown and disease manifestations may vary from patient to patient. Environmental influences may act as risk factors for the development of SSc (7, 8). Currently available single target therapies have not been effective either in mitigating the development of SSc or inducing its regression. In view of the complex, multifactorial pathogenesis of SSc, its effective treatment may require targeting multiple signaling pathways (9). Polypharmacology involves the design and use of pharmaceutical agents that act on multiple targets or disease pathways (10), which is particularly desirable in the case of complex, multifactorial diseases (11). Furthermore, the concept of “one drug – multiple targets” would minimize many unfavorable features of combination treatments such as simpler pharmacokinetics, improved target organ exposure, and fewer drug-drug interactions and adverse effects. This approach requires a systematic integration of different disciplines, including synthetic chemistry, in vitro/in vivo pharmacological and preclinical testing, and clinical studies for smoother translation from bench to bedside. SSc is one such disease that may benefit from the application of polypharmacology (9).


This proposal seeks to explore two potential therapeutic targets involved in pro-fibrogenic pathways, using a single molecular entity designed and developed ‘in-house’. One of the targets is iNOS, an enzyme encoded by the NOS2 gene and responsible for generating pro-inflammatory, reactive nitrogen species (12). The relevance of iNOS as a target is based on evidence for overproduction of nitric oxide (NO) in the pathogenesis of SSc (13, 14). iNOS is expressed in the endothelium, smooth muscle cells, fibroblasts, macrophages and many other cell types, is robustly induced by inflammatory mediators and cytokines (12), and its activity has been reported to increase in SSc (13). In contrast, the activity of a constitutively expressed form of NOS located in the vascular endothelium (eNOS, encoded by the NOS3 gene) has been reported to be reduced in SSc (15), resulting in a vasoconstricted and proinflammatory environment in association with tissue damage (16). At inflammatory sites, the iNOS-mediated formation of NO is increased in inflammatory cells such as macrophages or activated fibroblasts. Immuno-histological studies of scleroderma skin show that, as the disease progresses to the later fibrotic stages, the expression of iNOS is upregulated (17). Previous studies also demonstrate that SSc lung macrophages express high levels of iNOS and produce a high quantity of ONOO’ anions (17). In SSc patients, increased production of NO is suggested by increased expression of iNOS in endothelial cells, fibroblasts, mononuclear cells infiltrating SSc skin (16) and alveolar macrophages (15). The pathogenic role of iNOS is eloquently dissected by the work of Cotton et al. which proposes the active role of iNOS-induced NO production in endothelial cell damage and advances the concept of iNOS inhibition as a viable therapeutic strategy for SSc (18). However, iNOS inhibitors used in preclinical studies lack oral bioavailability (19), whereas more recently developed, orally bioavailable iNOS inhibitors had disappointingly low therapeutic efficacy in clinical trials involving inflammatory diseases (20).


An additional target that is becoming increasingly relevant in the modulation of fibrotic responses is the endocannabinoid (EC) system. ECs are lipid-signaling molecules that act through cannabinoid receptors CB1 and CB2. ECs acting via CB1R promote fibrosis in multiple organs including skin (21), liver (22-24), kidney (25), and heart (26). Besides, CB1R activation is pro-inflammatory (27). CB1R have recently been linked to radiation-induced pulmonary fibrosis in mice (28). Recent evidence including work in our lab indicate that CB1R antagonism prevents fibroblast activation and exerts a potent antifibrotic effect (29). The role of CB1R as a pro-fibrotic receptor has also been confirmed in fatty acid amide hydrolase knock-out mice, in which elevated levels of ECs induced fibrosis in a CB1R-dependent manner (30). In addition to fibrosis, numerous studies have documented that an overactive EC/CB1R system contributes to visceral obesity and its complications (31), including type-2 diabetes (27), and also play a role in the pathology of alcoholic liver disease (32) and viral hepatitis (33). Conversely, CB1R blockade has beneficial effects in preclinical models of these conditions as well as in overweight individuals with metabolic syndrome (34). However, rimonabant and related brain-penetrant CB1R antagonists cause psychiatric side effects due to blockade of CB1R in the CNS, which halted their therapeutic development. Non-brain-penetrant CB1R antagonists have recently been reported to retain the metabolic benefit of globally acting compounds without blocking CB1R in the CNS and thus without related behavioral effects (27, 35-37). Efforts to engage CB1Rs for mitigating fibrosis would require antagonists with limited brain exposure in order to avoid neuropsychiatric side effects (37).

With these principles in mind, IC has developed and patented orally bioavailable, dual-target compounds that selectively block peripheral CB1R due to their limited brain penetrance and also directly inhibit iNOS activity (38). These compounds have several features for optimal therapeutic efficacy and safety. The hybrid compound serves as a pro-drug and a carrier for the iNOS inhibitory moiety, facilitating its delivery to target organs such as skin, kidney, lung, and liver, resulting in high target exposure. IC has identified lead compounds and screened them for optimally druggable pharmacodynamic and pharmacokinetic properties. For the lead compound MRI-1867, CB1R was the only high-affinity (Ki <1 µM) target among selected receptors, ion channels and enzymes (Cerep Safety44 screen, DiscoveRx panel of 192 GPCRs) and had an acceptable safety and stability profile using non-GLP in vitro tests (AMES test, hERG assay, microsomal stability, plasma stability, CYP inhibition, CYP phenotyping) (24). A proof of concept study in 2 mouse models of liver fibrosis (24) and in bleomycin-induced lung fibrosis indicated improved anti-fibrotic efficacy relative to the efficacy of a single target CB1R antagonist or iNOS inhibitor (39). The IC in vitro and in vivo data in murine models of liver fibrosis and pulmonary fibrosis provide a strong rationale for testing this compound in dermal fibrosis models of scleroderma.


The scope of the CRADA Research Plan is limited to the assessment of the therapeutic potential of CB1R/iNOS dual-target inhibitors in animal models of scleroderma for the treatment and prevention of fibrotic conditions related to the progression of scleroderma.


Research Strategy: The CRADA Parties will build upon the hypothesis that the EC/CB1R system and iNOS are both pro-fibrogenic, and combined inhibition of these targets by a single compound would improve therapeutic outcome in scleroderma. Parties plan to test the novel dual-target compound MRI-1867 in bleomycin-induced subcutaneous fibrosis model in multi drug resistance 1a and 1b [            ]/ breast cancer resistance protein [                                   .]


Bleomycin-induced scleroderma model Subcutaneous injections of bleomycin induce skin and pulmonary fibrosis (40), quantifiable histologically and biochemically. A recent modification in this protocol generated reproducible and more homogenous skin and lung fibrosis lesions mimicking human SSc, with interstitial lung disease-like manifestations (41). However, IC investigators observed that daily subcutaneous bleomycin administration significantly increased efflux transporters such as [          ,] [          ] and [       ] in skin that resulted in drastically reduced skin exposure to test compount (MRI-1867), which is a substrate for these transporters. Therefore, this experimental artifact would preclude preclinical efficacy testing using wild-type mice in bleomycin-induced skin fibrosis model. The IC investigators found that bleomycin also induced skin fibrosis in [                     ] [                     ] which was comparable to that in wt mice. Importantly, MRI-1867 skin exposure was not reduced in the [                 ] and was similar to that in bleo-treated wildtype mice. Therefore [                                   ] [       ] will be used in these proposed studies.


Specific Aim 1:


Previously conducted study will be repeated testing S-MRI-1867 at [             ] dose in [                                                                 ] fibrosis model.

Approaches for Aim 1:


1.1.Skin abnormalities and fibrosis will be assessed histologically (H&E and Masson’s trichrome), biochemically (hydroxyproline content) and by measuring profibrotic gene expression (TGFβ, αSMA, fibronectin, collagen, TIMP1).


Specific Aim 2: Dose ranging of S-MRI-1867 for skin exposure


Approaches for Aim 2:


2.1.Tissue distribution and pharmacokinetics of S-MRI1867 will be tested in [                                    ] at different doses prior to starting dose ranging study in order to verify proportional exposure at different doses via single acute administration of the compound [                                    .]


Specific Aim 3: Assessing effective dose range of S-MRI-1867 treatment in bleomycin-induced skin fibrosis in [                                        .]


Approaches for Aim 3:


S-MRI-1867 at doses of [                    ] (maybe increase to [           ] based on AIM1) will be used in treatment paradigm using 12 mice in each group. In the same study we will also include [           ] of ibipinabant as a brain penetrant CB1R antagonist, which is also structural analogue of S-MRI-1867. Comparing ibipinabant and S-MRI-1867 will help us understand the contribution of the secondary target to therapeutic efficacy.


3.1.Skin abnormalities and fibrosis will be assessed histologically (H&E and Masson’s trichrome) and biochemically (hydroxy-proline content).


3.2.Protein and gene expression levels of CB1R and iNOS will be investigated by immunohistochemistry and real-time PCR.


3.3.Endocannabinoids will be measured by LC-MS/MS.


3.4.Inflammatory and fibrogenic gene markers will be measured in a separate study using skin samples after the dose assessment study has been completed.


Impact: Systemic sclerosis is a debilitating, multifactorial, autoimmune condition, in which the body’s immune system attacks healthy tissues. While certain mutations in human leukocyte antigen (HLA) genes have been implicated, numerous environmental factors have been associated with altered progression of scleroderma. The CRADA Parties propose here an investigation into the potential therapeutic utility of directly targeting CB1R and iNOS, with high translation potential, to treat and prevent fibrotic conditions related to the progression of scleroderma. The goals for this project are to test the hypothesis that an overactivity of iNOS and CB1R contribute to fibrogenesis in scleroderma, by analogy to our earlier findings with other forms of fibrosis. Parties propose to explore the therapeutic efficacy of combined blockade of peripheral CB1R and iNOS in bleomycin-induced skin fibrosis and inflammation and determine whether it offers therapeutic benefit over targeting only one of these proteins. In addition to testing the NIAAA lead hybrid inhibitor, the Parties will test/develop additional molecular entities with druggable pharmacological properties within this paradigm. The results of the proposed experiments will shed further light on the signaling pathways involved in scleroderma and may uncover novel targets for its treatment and prevention.

Future Intentions:


Should both the results of the CRADA Research Plan and the results from future IND-enabling studies warrant advancement of compound MRI-1867 into clinical development for systemic sclerosis (scleroderma), it is the intent of the IC, after receiving approval from the National Center for Advancing Translational Sciences (NCATS), to provide the CRADA Collaborator with either a cross-reference letter of its Investigational New Drug Application for compound MRI-1867 to the U.S. Food and Drug Administration (FDA), or access to the IND-enabling data (obtained through IC’s partnership with the NCATS Therapeutics for Rare and Neglected Disease (TRND) program) for CRADA Collaborator to file a Collaborator-sponsored IND for compound MRI-1867 (or potentially other CB1/iNOS dual action inhibitors identified pursuant to the performance of the CRADA Research Plan) in system sclerosis (scleroderma). For clarity, these IND-enabling data will be used by the Collaborator solely to obtain an IND for the clinical testing of the lead compound, MRI-1867 (or other CB1/iNOS dual action inhibitors identified pursuant to the performance of the CRADA Research Plan), in systemic sclerosis, and will not be shared with any outside parties without the written consent of the IC.
