©2023 Relmada - All rights reserved Disclosures 2 Certain statements contained in this presentation or in other documents of Relmada Therapeutics, Inc. (the “Company”), along with certain statements that may be made by management of the Company orally in presenting this material, may contain “forward - looking statements.” These statements can be identified by the fact that they do not relate strictly to historic or current facts. They use words such as “estimate,” “expect,” “intend,” “believe,” “plan,” “anticipate,” “projected” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance or condition. These statements are based upon the current beliefs and expectations of the Company’s management and are subject to significant risks and uncertainties. Statements regarding future action, future performance and/or future results, those relating to the timing for completion, and results of, scheduled or additional clinical trials and the FDA’s or other regulatory review and/or approval and commercial launch and sales results (if any) of the Company’s formulations and products and regulatory filings related to the same may differ from those set forth in the forward - looking statements. Peak sales and market size estimates have been determined on the basis of market research and comparable product analysis, but no assurances can be given that such sales levels will be achieved, if at all, or that such market size estimates will prove accurate. Because actual results are affected by these and other potential risks, contingencies and uncertainties, the Company cautions investors that actual results may differ materially from those expressed or implied in any forward - looking statement. It is not possible to predict or identify all such risks, contingencies and uncertainties. The Company identifies some of these factors in its Securities and Exchange Commission (“SEC”) filings on Forms 10 - K, 10 - Q and 8 - K, and investors are advised to consult the Company’s filings for a more complete listing of risk factors, contingencies and uncertainties affecting the Company and its business and financial performance. The Company assumes no obligation to update forward - looking statements as circumstances change. Investors are advised to consult further disclosures that the Company makes or has made on related subjects in the Company’s Form 10 - K, 10 - Q and 8 - K reports.

Relmada data on file Clinical data has demonstrated: • Robust, rapid, and sustained statistically significant antidepressant effects on all tested scales 4 • Rapid onset: significant efficacy effects by Day 4 4 • Favorable safety and tolerability profile consistent across all studies 4,5,6 : no opioid and no psychotomimetic adverse events and no metabolic side effects 4,5,6 • Orally administered, once - daily tablet Novel Mechanism of Action: preferential targeting of NMDAR channels potentially associated with MDD 1,2,3

Esmethadone 1 (REL - 1017) is a novel NMDA receptor antagonist Esmethadone preferentially blocks tonically hyperactive GluN2D receptor subtypes 2 , potentially increasing BDNF 3 , decreasing neuroinflammation 4 and restoring physiological neuroplasticity 5,6,7 . NMDA: N - methyl - D - aspartate GluN2D: Glutamate NMDA receptor with 2D subunits BDNF: brain - derived neurotrophic factor MDD: major depressive disorder Synaptic spines increase in size within 24 hours of administration 8 . Esmethadone is devoid of dissociative effects 9 , has no meaningful abuse potential 10 and is administered orally once - daily. Images from published article 8 Receptor, synapses and brain images are artistic renditions 8 ©2023 Relmada - All rights reserved 8. A single dose of esmethadone increases synaptic spines ( Fogaca 2019 ) 9. Esmethadone does not cause dissociative effects ( Shram 2023 ) 10. Esmethadone differs pharmacologically from levomethadone because it is devoid of clinically relevant opioid activity. Esmethadone has no meaningful abuse potential in healthy subjects ( Bernstein 2019 ), patients with MDD ( Fava 2022 ) and recreational substance users ( Shram 2023 ) 1. Esmethadone is a promising non - dissociative NMDAR antagonist antidepressant ( Fava 2023 ) 2. Esmethadone preferentially targets tonically hyperactive GluN2D receptors ( Bettini 20222A ) 3. Esmethadone increases BDNF release ( Fogaca 2019 ; De Martin 2021 ) 4. Esmethadone reduces calcium influx induced by quinolinic acid ( Bettini 2022B ) 5. Esmethadone restores impaired neuroplasticity ( Fogaca 2019 ; Stahl 2022 ) 6. Impaired neuroplasticity and neuroinflammation may be central to the pathophysiology of MDD ( Cooper 2023 ) 7. Esmethadone is a promising neuroplastogen ® that could transform the current treatment of MDD ( Cooper 2023 )
