Objective: To explore the long-term safety and efficacy of canine allogeneic
mesenchymal stromal cells (MSC) administered intra-articularly as single or repeated
injections in appendicular joints of dogs affected by moderate to severe refractory
osteoarthritis.
Study Design: 22 pet dogs were recruited into a non-randomized, open and
monocentric study initially administering one cellular injection. A second injection was
offered after 6 months to owners if the first injection did not produce expected results.
Materials and Methods: Anti-inflammatory treatment (if prescribed) was discontinued
at last one week before the onset of treatment. Each injection consisted of at least 10
million viable neonatal allogeneic mesenchymal stromal cells obtained from fetal adnexa.
Medical data was collected from veterinary clinical evaluations of joints up to 6 months
post-injection and owner’s assessment of their dog’s mobility and well-being followed for
a further 2 years when possible.
Results: Mild, immediate self-limiting inflammatory joint reactions were observed in 5/22
joints after the first injection, and in almost all dogs having a subsequent injection. No
other MSC-related adverse medical events were reported, neither during the 6 months
follow up visits, nor during the long-term (2-years) safety follow up. Veterinary clinical
evaluation showed a significant and durable clinical improvement (up to 6 months)

Adipose-derived stem cells • Fresh • Allogeneic • Cats • Gingivostomatitis •

We previously demonstrated the efficacyof fresh, autologous, adipose-derived MSCs (ASCs) to treat feline chronic gingivostomatitis (FCGS),a chronic oral mucosal inflammatory disease similar to human oral lichen planus. Here, we investi-gate the use of fresh allogeneic ASCs for treatment of FCGS in seven cats. Radiolabeled ASCs werealso tracked systemically. Each cat received two intravenous injections of 20 million ASCs, 1 monthapart. Oral inflammation, blood lymphocyte subsets, anti-fetal bovine serum antibody levels, ASCcrossmatching and serum proteins and cytokine concentrations were determined. Four of the 7cats (57%) responded to treatment [complete clinical remission (n 5 2) or substantial clinicalimprovement (n 5 2)]. Three cats were nonresponders. Prior to therapy, most cats had increasedcirculating CD81 T cells, decreased CD8lo cells, and a decreased CD4/CD8 ratio, however clinicalresolution was not associated with normalization of these parameters. Nonresponders showedmore severe systemic inflammation (neutrophilia, hyperglobulinemia and increased interferongamma and tumor necrosis factor alpha concentration) prior to ASC therapy. Clinical remissiontook up to 20 months and no clinical relapse has occurred. A higher fraction of radiolabeled ASCswere identified in the oral cavity of FCGS affected cats than the control cat. The administration offresh, allogenic ASCs appeared to have lower clinical efficacy with a delayed response as comparedto the fresh, autologous ASCs. In addition, the mechanism(s) of action for autologous and allogenicASCs may differ in this model of oral inflammation. STEM CELLS TRANSLATIONAL MEDICINE2017;00:000–000SIGNIFICANCE STATEMENTThis study is the first to demonstrate the safety and efficacy of fresh, allogeneic adipose derivedstem cells systemic therapy for a naturally occurring, inflammatory disease in cats. We demon-strate that this therapy resulted in delayed clinical and histological resolution and immune mod-ulation as compared to autologous therapy. We also demonstrated that the mechanism(s) ofaction for autologous and allogenic adipose-derived MSCs (ASCs) may differ in this model oforal inflammation. Finally, we show that ASC in cats are initially engrafted to the lungs and thata higher fraction of cells were identified in the oral cavity of feline chronic gingivostomatitisaffected cats than control.INTRODUCTIONStem cell-based therapy and research have madeexceptional progress in the last decade. Apartfrom their capacity to regenerate damaged tis-sues, mesenchymal stem cells (MSCs) possessunique immunomodulatory capabilities and haveimproved the outcome of clinical diseases withaberrant immune responses [1–4]. We recentlypublished on the safety and efficacy of autologous
adipose-derived mesenchymal stem cells (ASCs)to treat naturally occurring feline chronic gingivos-tomatitis (FCGS). FCGS is a large animal model ofimmune-mediated oral mucosal inflammatory dis-eases of humans including oral lichen planus(OLP), recurrent aphthous stomatitis, pemphigus,and pemphigoid [1]. In both human and cats,these diseases result in painful mucosal lesionsthat markedly reduce quality of life and oftenrequire long-term immunosuppressive therapy

Abstract
Background: There is a critical need for proven drugs other than non-steroidal anti-inflammatory drugs fortreatment of degenerative joint disease (DJD) pain in dogs. Antibodies against nerve growth factor (NGF) areanalgesic in rodent models and in humans with DJD. This pilot study aimed to evaluate the efficacy of a novelcaninised anti-NGF antibody (NV-01) for the treatment of DJD pain in dogs. In a randomized, parallel group,stratified, double masked, placebo controlled, proof of principle clinical pilot study design, 26 dogs with DJDreceived NV-01 (200 mcg/kg IV) or placebo on day 0 (D0). In addition to objective accelerometry measures, ownerscompleted clinical metrology instruments (Client-Specific Outcome Measures [CSOM], Canine Brief Pain Inventory[CBPI] and Liverpool Osteoarthritis in Dogs Index [LOAD]) on D0, D14 and D28. CBPI subscales (pain severity [PS]and pain interference [PI]), CSOM and LOAD scores were evaluated within and between groups for change overtime. Recognized success/failure criteria were applied and success compared between groups.
Results: CBPI PS and PI scores significantly improved in the NV-01 group (PS: D0-14, P = 0.012 and D0-28, P = 0.019;PI: D0-14, P = 0.012 and D0-28, P = 0.032) but not in the placebo group. CSOM scores showed similar patterns witha significant difference between within-group changes at D14 and D28 (P = 0.038 and P = 0.009, respectively), andsignificantly more successes at D28 (P = 0.047). LOAD scores significantly improved in the NV-01 group (D0-14,P = 0.004 and D0-28, P = 0.002) but not in the placebo group. There were significant differences between thegroups for change in LOAD score at D14 (P = 0.014) and D28 (P = 0.033). No side effects were noted. Activity in theNV-01 group increased over the study period compared to placebo (P = 0.063) and the difference between thegroups for change in activity over the time period 9am-5pm (8 hours) was significant (P = 0.006).
Conclusions: These pilot data demonstrate a positive analgesic effect of anti-NGF antibody in dogs suffering fromchronic pain. The magnitude of the effect appeared identical to that expected with an NSAID.

Background: Neutralizing antibodies against nerve growth factor (NGF) are analgesic in rodent models, naturally occur-ring degenerative joint disease (DJD) pain in dogs, and chronic pain in humans.
Objectives: To evaluate the efficacy of a fully felinized anti-NGF antibody (NV-02) for the treatment of DJD pain andmobility impairment in cats.
Animals: Thirty-four client-owned cats with DJD-associated pain and mobility impairment.Methods: In a placebo-controlled, pilot, masked clinical study, cats were randomized to a single treatment with NV-02
(0.4 mg/kg SC [n = 11] or 0.8 mg/kg SC [n = 12]) or placebo (saline, SC [n = 11]). Activity was measured objectively. Addi-tionally, owners completed clinical metrology instruments (client-specific outcome measures [CSOM] and feline musculoskele-tal pain index [FMPI]) on days 0 (screening), 14 (baseline), 35, 56, and 77. A repeated-measures model was used to evaluatethe objective activity data.
Results: NV-02 significantly increased objectively measured activity overall (P = .017) and at 2 (P = .035), 3 (P = .007), 4(P = .006), 5 (P = .007), and 6 (P = .017) weeks after treatment. CSOM scores (P = .035) and pain (P = .024) showed a sig-nificant effect of treatment 3 weeks after administration. In the treatment group, 83% of the owners correctly identified thetreatment administered compared with 45% of owners in the placebo group (P = .013). No treatment-related adverse effectswere identified.
Conclusions: These pilot data demonstrate a 6-week duration positive analgesic effect of this fully felinized anti-NGF anti-body in cats suffering from DJD-associated pain.

Many adult and geriatric cats have radiographicevidence of degenerative joint disease (DJD),1,2
and a large proportion of these have associated chronicpain, manifested as alterations in mobility and activity.In the United States, there is no approved medicationfor the long-term treatment of chronic pain in cats,despite the clear need for such a treatment.Currently, the nonsteroidal anti-inflammatory drug
(NSAID) meloxicam is approved in Europe for use intreating chronic pain in cats, but has not been approvedfor this use in the United States. There are concerns
about the use of NSAIDs for long periods of time incats, especially because the majority of cats presentingwith DJD-associated pain have evidence of chronic kid-ney disease.3 Because of these concerns, dosages lowerthan the European-approved dosage of meloxicam havebeen tried, and there are several suggestions from open-label studies that these lower dosages are effective in themanagement of DJD-associated pain in cats.4,5 Only oneblinded, placebo-controlled study assessing a dosagelower than the approved 0.05 mg/kg daily dosage hasbeen performed, and that study found that a dosage of0.035 mg/kg daily produced measureable improvementover a 3-week period of administration.6,7 Indeed, only 2placebo-controlled, masked, clinical studies of the effi-cacy of meloxicam in cats have been published.6–8
