Neuroscience Oncology Research and Development Strategy: Focus on High-Value Candidates in Two Key Therapeutic Areas Psychiatry Neurology Engineered Cytokines Small Molecules

Nemvaleukin Alfa (“nemvaleukin”) Formerly referred to as ALKS 4230 Novel investigational immuno-oncology candidate designed to leverage proven anti-tumor effects of interleukin-2 (IL-2) pathway Stable, inherently active, single polypeptide designed to selectively bind to the intermediate-affinity IL-2 receptor complex and expand tumor-killing CD8+ and Natural Killer (NK) T cells, and have negligible effects on Treg expansion

Activation of IL-2 Pathway Offers Broad Potential Clinical Utility IL-2 is a natural regulator of the activity of lymphocytes involved in the immune response Recombinant human IL-2 as monotherapy can drive complete and durable responses in certain tumor types, but its toxicity profile significantly limits its broad use A molecule with differentiated tolerability that targets the IL-2 pathway could be complementary to a wide range of other therapeutic approaches Cancer antigen presentation Vaccines IFN-a Anti-CD40 (agonist) TLR agonists 5 3 2 1 7 6 Infiltration of T cells into tumors CAR-Ts Recognition of cancer cells by T cells CAR-Ts Chemotherapy Radiation Killing of cancer cells Radiation Chemotherapy Targeted Anti-PD-(L)1) Release of cancer cell antigens Chemotherapy Radiation therapy Targeted therapy Priming and activation of Natural Killer and CD8+ T cells IL-2 PD1/L CTLA4 Tumor Lymph node Blood vessel 4 Trafficking of T cells to tumors Anti-VEGF (including TKIs) Range of Potential Therapeutic Combinations with Nemvaleukin Adapted from Chen and Mellman, 2013.

Nemvaleukin Development Strategy CONFIRM mechanism through immune response SEEK anti-tumor activity signals FOCUS on initial registration pathways BROADEN program to maximize value

Nemvaleukin Development Strategy Demonstrate clinical pharmacodynamic response reflective of intermediate-affinity IL-2 receptor selectivity Dose-dependent, selective expansion of NK and CD8+ T cells Minimal and non-dose dependent changes in peripheral regulatory T cells Advance into phase 2 expansion stage of ARTISTRY-1 and ARTISTRY-2 Additional phase 1 pharmacokinetic/pharmacodynamic, safety, and tolerability data for subcutaneous nemvaleukin to be submitted to upcoming medical meeting CONFIRM mechanism through immune response SEEK anti-tumor activity signals FOCUS on initial registration pathways BROADEN program to maximize value

Nemvaleukin Development Strategy Demonstrate monotherapy anti-tumor efficacy Single-agent activity observed in mucosal melanoma and renal cell carcinoma with IV nemvaleukin Demonstrate anti-tumor activity in combination with PD-1 inhibitor Durable and deepening responses observed with IV nemvaleukin in combination with pembrolizumab Responses in multiple solid tumor types (melanoma, ovarian, breast, cervical, gastro-esophageal and pancreatic) with IV nemvaleukin CONFIRM mechanism through immune response SEEK anti-tumor activity signals FOCUS on initial registration pathways BROADEN program to maximize value

Nemvaleukin Development Strategy Select initial tumor types to pursue for registration of IV nemvaleukin Monotherapy: Mucosal melanoma Combination with pembrolizumab: Platinum-resistant ovarian cancer (PROC) Advance discussions on registration plans with regulatory agencies Initiate studies with IV nemvaleukin Mucosal melanoma: Planned study start in H1 2021 PROC: Planned study start in mid-2021 CONFIRM mechanism through immune response SEEK anti-tumor activity signals FOCUS on initial registration pathways BROADEN program to maximize value

Nemvaleukin Development Strategy Identify and select additional tumor types and combinations to pursue Earlier lines of therapy versus standard of care Combinations with targeted and immuno-oncology agents Combinations with radiotherapy, chemotherapy, or other therapies Strategic collaboration CONFIRM mechanism through immune response SEEK anti-tumor activity signals FOCUS on initial registration pathways BROADEN program to maximize value

ALKS 1140: Novel CoREST-Selective HDAC Inhibitor for Neuropsychiatric Indications First candidate nominated from platform of selective HDAC inhibitor compounds Inhibition of the CoREST HDAC complex is a novel approach to increase functional synaptic connections and synaptic integrity Initial clinical development plans focused on basket of indications, including rare neurodegenerative and neurodevelopmental diseases as well as common psychiatric diseases HDAC: Histone deacetylase CoREST: Co-repressor of repressor element-1 silencing transcription factor

Synapses Play a Vital Role in Brain Function Synapses are the points of communication within the network of neurons that make up the brain Synaptic function is critical to brain development, learning and memory Synaptogenesis is the formation of synapses between neurons in the nervous system that occurs throughout a healthy person's lifespan

Many neurological disorders are characterized by synaptic pathology Abnormal density of dendritic spines Synapse loss Aberrant synaptic signaling and plasticity Synapses are a critical target to slow progression and preserve cognitive and functional abilities in multiple neuropsychiatric, neurodegenerative and neurodevelopment disorders Synaptic Loss: Pathologic Correlate of Cognitive Decline Onwordi et al, Nature Communications. 11, 246 (2020). https://www.nature.com/articles/s41467-019-14122-0#citeas Impaired Brain Function Healthy Control

ALKS 1140 Selectively Modulates the Function of the CoREST HDAC Complex Criteria achieved for nomination of ALKS 1140 as a candidate to improve synapse formation and synapse function: Selectively inhibits HDAC1/2 specifically associated with the CoREST complex Brain permeable Designed to avoid hematopoietic side effects Increased synaptic density in preclinical models Plan to begin first-in-human trials in 2021 LSD1, HDAC1, CoREST1 and ALKS 1140 modeled into the small angle X-ray scattering (SAXS) envelope of the CoREST complex (Cell Reports 30:2699, 2020)
