Outlook Therapeutics Provides Update

on Progress Towards First Approved Ophthalmic Formulation of Bevacizumab-vikg for Advanced Macular Degeneration

MONMOUTH JUNCTION, N.J., September 30, 2020 - Outlook Therapeutics, Inc. (Nasdaq: OTLK) is a late clinical-stage biopharmaceutical

company developing the first FDA-approved ophthalmic formulation of bevacizumab-vikg (LYTENAVA ) for use in retinal indications

(known as ONS-5010). Outlook Therapeutics is advancing on multiple fronts, including: progress on its Phase 3 clinical program,

manufacturing and regulatory activities, and global strategic partnering negotiations, all leading to the planned commercial launch

of ONS-5010 anticipated in 2022. In addition, Outlook Therapeutics recently completed a strategic partnership for commercialization

in Greater China and is in discussions with other strategic partners for commercial launches in the United States, Asia and Europe.

Progress Drives ONS-5010 Towards U.S. and EU Filings in 2021

Therapeutics has already demonstrated both safety and efficacy through a recently reported clinical experience trial and, separately,

has also completed enrollment of 227 patients in its U.S.-based Phase 3 pivotal trial. The clinical experience trial gives Outlook

Therapeutics a high level of confidence in the outcome of the ongoing fully-enrolled pivotal trial. Pivotal data are expected mid-2021

followed by submission of a U.S. Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA). If the BLA

is approved, it will result in 12 years of marketing exclusivity. Outlook Therapeutics is on track for both U.S. BLA filing and

EU Marketing Authorization Application (MAA) filings in 2021.

Addresses Significant Unmet Medical Need

unapproved repackaged IV Avastin from compounding pharmacists is widely used by retinal specialists, extensive marketing research

has indicated that there is a significant unmet medical need for an approved ophthalmic formulation of bevacizumab that removes

both the product liability and safety concerns of a repackaged product. Once approved, Outlook Therapeutics' ONS-5010 will

reduce the need for use of unapproved repackaged IV Avastin from compounding pharmacists. Upon approval, ONS-5010 will be

the first ophthalmic formulation of bevacizumab-vikg approved as an anti-VEGF therapy addressing vision loss from wet age-related

macular degeneration (wet AMD). Outlook Therapeutics also intends to seek approval of ONS-5010 for other approved indications,

including branch retinal vein occlusion (BRVO) and diabetic macular degeneration (DME).

Planning Activities Underway

launch planning has begun, including distribution, physician and patient outreach, key opinion leader support and payor community

engagement. With an enhanced safety and cost-effective profile, Outlook Therapeutics expects ONS-5010 to be widely adopted by payors

and clinicians worldwide and to become the first-line drug of choice for payor-mandated "step edit" in the United

States for retinal indications.

market research indicates that ONS-5010, if approved, will be a significant therapy in the retinal anti-VEGF market, currently

estimated to be in excess of $13 billion worldwide.

and Regulatory Progress Towards Commercialization

Therapeutics is working with FujiFilm Diosynth Biotechnologies (Fuji) and Ajinomoto Bio-pharma Services (AjiBio) to provide product

manufacturing in best-in-class cGMP global manufacturing facilities. The Outlook Therapeutics strategy also provides greater safety

confidence to both clinicians and patients by reducing the current practice of using compounding facilities, which have raised

concerns about product quality that impact patient safety. Outlook Therapeutics has completed technology transfer and scale-up

consistent with global cGMP standards with both Fuji and AjiBio.

Therapeutics also has executed a supply agreement for a best-in-class pre-filled ophthalmic syringe that will provide both ease-of-use

for clinicians and add to ONS-5010's safety profile over the current unapproved therapies that have caused problems related

to syringe malfunction, contamination, etc.

the regulatory front, Outlook Therapeutics has tentatively been granted an ATC code for ophthalmic bevacizumab by the World Health

Organization. Also, SME Entity Status has been granted by the EMA.

with Potential Strategic Partners Progressing

above accomplishments and the potential of ONS-5010 have captured the attention of potential strategic partners. Outlook Therapeutics

is engaged with several life sciences companies that could result in a strategic partnership and definitive agreement for ONS-5010

as soon as the end of 2020. Recently, Outlook Therapeutics announced a joint venture with Syntone Technologies for commercializing

ONS-5010 in Greater China. Syntone Technologies also made a substantial equity investment in Outlook Therapeutics. Outlook Therapeutics

anticipates similar interest from biologic commercial partners in other countries.
