Scleroderma The word “scleroderma” comes from two Greek words: “sclero” meaning hard, and “derma” meaning skin. There are approximately 200,000 patients in USApproximately 75,000-80,000 have systemic sclerosis (SSc) Scleroderma Localized Systemic Scleroderma or Systemic Sclerosis

SSc—Epidemiology Rare diseaseEstimated prevalence1 US 276/millionEurope 88-160/millionEstimated incidence 18.7 cases/ million/ year2 With US population at ~ 328 million people, there are ~ 6,000 new SSc cases diagnosed each year 1Chifflow H Semin Arthritis Rheum 37:223-235 2Mayes et al.

Why a Combined Response Index for SSc? SSc has validated outcomes for individual manifestations SSc is a multisystem disorderCombined indices successful in other complex systemic rheumatic diseases:RCTs FDA approval of new therapiesRA-ACR Responder Index/Disease activity index: joint count, HAQ, APRs, global assessmentsPsoriatic Arthritis--Responder index: joint count, HAQ-DI, APRs, global assessments We seek approaches to treat the underlying disease; thus, we want measures of overall disease ACR- American College of Rheumatology; HAQ-DI- Health Assessment Questionnaire, APR- Acute phase reactants

CM-101 Systemic Sclerosis Phase 2 Clinical Program Dr. Arnon Aharon Chemomab CMO

Phase 2 Trial in Diffuse Cutaneous Systemic Sclerosis (dcSSC) Territories: US, EU and Israel Number of sites: 100 sites globally Expected initiation – Q1/2022 Randomization 220 patients 1:1 Randomization ScreeningPeriod Treatment Period CM-101 10 mg/kg; I.V. Q3W Placebo; I.V. Q3W Week 45 EoT visit Week 48 Primary Endpoint Safety Follow-up Week 56 Diffuse Cutaneous Systemic Sclerosis Phase 2 Trial Design EoT- end of treatment; Q3W- once every 3 weeks; I.V. - Intravenous

Phase 2 Trial in Diffuse Cutaneous Systemic Sclerosis Targeted Population Key Inclusion Criteria Diagnosis of systemic sclerosis diffuse subtype early disease; < 5 years from onset of 1st non-Raynaud's sign/ symptommRSS > 15 and <45Evidence of disease activity: new/worsening of skin involvement, ILD, presence of TFRsStable background immunosuppressive treatment (limited to 60% of patients) We target dcSSc patients at a stage when early disease progress is significant These patients suffer inflammatory, fibrotic and vascular damage and are therefore well-positioned to benefit from CM-101 treatment Key Exclusion Criteria Diagnosis of limited subtype of systemic sclerosisSystemic sclerosis-like illness associated with environmental or ingested agentsUnstable SSc or end-stage organ involvementAdvanced pulmonary involvementSubjects who have SSc autoantibody status that is only positive for anti-centromere antibody ILD- Interstitial lung disease; mRSS- Modified Rodnan skin score; TFR- Tendon friction rubs; dcSSc- Diffuse cutaneous systemic sclerosis

Phase 2 Trial in Diffuse Cutaneous Systemic Sclerosis Efficacy Endpoints Primary endpoint Proportion of participants who meet the Revised CRISS responder criteria after 48 weeks of treatment Key secondary endpoint Change in Forced Vital Capacity (FVC) % predicted after 48 weeks of treatment We selected a primary endpoint that provides a holistic measurement of disease status with a key secondary endpoint of protecting lung function This approach is designed to support a label for the treatment of Systemic Sclerosis Secondary endpointsmRSS (modified Rodnan skin score), HAQ-DI (Health Assessment Questionnaire Disability Index), Physician Global Assessment (MDGA), Patient Global Assessment (PTGA), Diffusing Capacity of the Lung for carbon monoxide (DLCO), High Resolution CT (HRCT), quality of life and itching questionnairesExploratory/biomarker endpointsFibrotic biomarkers, measurement of immune cell infiltration by skin biopsy, nailfold capillaroscopy

CM-101 in Systemic Sclerosis – Key Clinical Program Features CM-101 development program aimed at a label for the treatment of Systemic Sclerosis - Addressing high unmet medical need in Systemic Sclerosis - Leveraging unique dual MoA of CM-101 to support a disease modification label - Targeting the whole dcSSc population, not limited to subset of patients with specific organ damage - Focus on evaluating patient benefit as a whole, as well as effect on individual organs such as lung and skin Study was designed in collaboration with KOLs and incorporates input from regulators - Selected dose was proven efficacious in animal models of SSc, improving both skin and lung symptoms - Revised CRISS is a holistic composite primary endpoint that best matches CM-101 dual MoA - One-year study duration enables detection of improvement in both inflammatory and fibrotic disease - This trial could potentially serve as 1st adequate and well controlled study toward registration A switch to the subcutaneous formulation is planned prior to Phase 3 trial
