About SELLAS Life Sciences Group

SELLAS Life Sciences is a late-stage biopharmaceutical company focused on the development of novel cancer immunotherapies and therapeutics for a broad range of orphan indications, as well as drugs targeting high-value neurological indications with significant unmet medical need, as well as orphan indications.

SELLAS was founded in 2012 and is headquartered in Zug, Switzerland. With most of the Company's management team based in the US, SELLAS is in the process of establishing a second base in New York City.

SELLAS has two late-stage, Phase 3-ready products poised to enter trials in Europe and the US in 2015/2016 across at least five indications in cancer and CNS diseases as well as an earlier stage highly innovative cancer therapeutic. The Company's WT1 vaccine for hematological malignancies and solid tumors has improved survival in patients with acute myeloid leukemia and shown additional clinical benefits in multiple myeloma and mesothelioma. SELLAS also is advancing a proprietary formulation of Zolpidem for basal ganglia disorders, including Parkinson's disease and the orphan indication PSP, and its TR1 product candidate, a novel fusion protein to induce apoptosis in cancer cells. The Company's management team has a proven track record of developing drugs and cancer vaccines throughout all stages of the product's life cycle, and the team has played key roles in bringing companies public, successfully out-licensing drug candidates, forming R&D partnerships with big pharma, and creating multiple alliances with centers of excellence.

About the WT1 Therapeutic Cancer Vaccine

The WT1 vaccine, licensed from Memorial Sloan Kettering Cancer Center, is a late-stage cancer immunotherapy targeting a broad spectrum of hematologic cancers and solid tumor indications including acute myeloid leukemia, mesothelioma, multiple myeloma, ovarian cancer, and multiple other cancers. The WT1 vaccine is comprised of four modified peptide chains that induce a strong innate immune response (CD4+/CD8+) against the WT1 antigen which is over-expressed in multiple malignancies.  The WT1 antigen was recently identified as the top potential immunotherapy cancer target by the National Cancer Institute.

SELLAS' WT1 vaccine was assembled from a set of immunogenic synthetic peptides, also using heteroclitic sequences that are capable of stimulating both CD4 and CD8 T cells. Initial studies with the vaccine have been conducted in patients with myeloid leukemias and thoracic cancers, such as lung cancer and mesothelioma. The Company's ongoing Phase 2 trial in acute myeloid leukemia (AML) has yet to reach median survival, which has surpassed 52 months; the standard survival is approximately 12 months for patients at the stage of disease as enrolled in the study. Based on encouraging results in SELLAS' initial studies, the Company expects to initiate in the first quarter of 2016 a Phase 3 trial of its WT1 vaccine in patients with AML and a Phase 2 study in multiple myeloma. SELLAS also anticipates data either later this year or in 2016 from an ongoing Phase 2 study of the WT1 vaccine in mesothelioma patients.

About TR1

SELLAS' TR1 product candidate is a novel fusion protein that supplies the normal wild type p53/p21 protein to cancer cells to trigger innate cell death mechanisms (apoptosis). P53/p21 is known as "the guardian of the genome" because it is the body's cellular first line of defense enabling the repair of damaged DNA or, if unsuccessful, triggers cell death. It is one of the most studied and pursued tumor suppressor proteins, as it is known to be inactivated in virtually all human cancers. In SELLAS' TR1 candidate, full-length p53/p21 is fused with the transporter protein Antennapedia (ANTP) to enhance the penetration of peptides through the blood-brain barrier.

TR1 is designed to be given in conjunction with conventional chemotherapy, acting in synergy with no added toxicity and without inconveniencing the patient. The Company also expects TR1 to be synergistic with radiotherapy and other biotherapies (such as monoclonal antibodies) because of its mode of action of switching on the apoptotic pathway in p53-mutated tumors. The Company is advancing its TR1 program toward IND-enabling studies, with the goal of commencing Phase 1 testing in 2016 and reporting initial data in 2017.

About Zolpidem

SELLAS is currently developing a proprietary formulation of high-dose Zolpidem, under the 505(b)(2) pathway for PSP.  Zolpidem's mechanism of action and therapeutic effects in CNS-related diseases, including PSP and Parkinson's, has been demonstrated in several studies. SELLAS expects to initiate a Phase 2b/3 study of high-dose Zolpidem for PSP in 1H 2016, with completion anticipated by 2H 2017. High-dose Zolpidem is eligible for Orphan Designation, Fast-Track Designation and Accelerated Approval for PSP. Method-of-use and formulation patents for high-dose Zolpidem extend out to 2026.

Zolpidem, in high doses of 25mg – 75 mg per day, is a selective agonist of GABA-A-BZ1 receptor that mediates anti-Parkinsonian effects in patients suffering from Parkinson's disease and related diseases. These receptors are upregulated in areas of the brain (such as the globus pallidus and substantia nigra) that are known to be abnormally overactive in PSP and Parkinson's patients, resulting in reduced activity of motor cortical areas. Zolpidem selectively inhibits these receptors in the affected areas resulting in improved activity of motor cortical areas.

Clinical studies report that high-dose Zolpidem has demonstrated statistically significant improvement in UPDRS motor score and improvement in voluntary saccadic eye movement for PSP patients. Additional beneficial effects included improvement in speech and vocalization, swallowing, vertical gaze and ocular pursuit, facial expression, speed of movement, bradykinesia, akinesia, limb and axial rigidity/extensor dystonia, PSP rating scale and Berg Balance score, dysphagia, drooling, agitation and aggressiveness.

SELLAS has an exclusive development and licensing agreement with Catalent Pharma Solutions to support the development and formulation of high-dose Zolpidem. SELLAS will utilize Catalent's proprietary OptiDose technology, which allows for sustained-release and combination dose forms, as well as administration as a monotherapy or combination therapy with three sustained-release reservoir compartments per tablet to cover 12 – 24 hour symptom relief.
