Cochlear Pathology and the Impact of High Frequencies on Speech Perception Sumit Dhar, PhD Hugh Knowles Professor of Hearing Science and Associate Provost for Faculty at Northwestern University 42

Disclosures Honorarium from Frequency TX to review all clinical data from past studies and assess planned clinical trial. Participated on external panel of KOL’s on auditory science. Primary employment at Northwestern University. Parts of my salary are paid by the NIH and PCORI. I receive royalty and consulting fees from Plural Publishing. I receive licensing fees from Etymotic Research. I serve on the Board of Directors of the American Auditory Society. I serve on the Board of Directors of LeAP (Language Empowers All People). 43

Why Treat the High-Frequency Region of the Cochlea? 44

Common Forms of Hearing Loss is Dominant in the Highest Frequencies 20.5 dB @ 18kHz in 20-24 yo 56.5 dB @ 15kHz in 44-49 yo 65 dB @ 15kHz in 60-64 yo Current limit of clinical tests N=976; Lee et al., 2012; Hunter et al., 2020 45 45

How Does High Frequency Cochlear Function Influence Speech Perception? 46

Speech Perception Influenced by Cochlear Function in High-Frequency Regions N = 921 DPOAE levels between 12.5 – 16 kHz drive speech perception in noise scores 2 (p = 0.047, R = 0.017) more than audibility. Speech perception is the complaint that leads patients to seek treatment. Speech perception is the the long-standing gold standard in determining functional outcomes of any treatment for hearing loss. Current limit of clinical tests Stiepan et al., 2020 47 47 Threshold (dB FPL)/OAE Level (dB SPL)

Should We Expect Heterogeneity in Treatment Outcomes? 48

Response Variability Predicted by Cochlear Heterogeneity Heterogeneity of response magnitude and response timeline is the reality of all hearing loss treatments • Decades of data from cochlear implants and hearing aids definitively demonstrate heterogeneity in response • Likely driven by varying damage and rates of plasticity in the auditory system. 49

Impact of Heterogeniety on Clinical Study Planning Etiology and duration of pathology is heterogenous across individuals. Frequency TX’s approach of exploring various etiologies and pathologies in early studies was the necessary approach to identify target responder populations. The design and controls put in place for the next study represent the best path forward. 50

Takeaways Treating the HF region of the cochlea is critical. Function of the HF region can influence speech perception. Heterogeneity of response is a reality of all treatments for hearing loss. 51

Addressing Placebo Response in Clinical Trials: Best Practices Steven D. Targum MD Clinical Consultant Scientific Director, Signant Health 59

The Inherent Challenge of Clinical Trials: Reliability • Challenges to study reliability include: • Misplaced enrollment incentives • Expectation bias • Pre-randomization symptom fluctuation • Lack of ratings precision and consistency 61

The Frequency Experience in FX-322-202 Can Inform the Next Study • Post-hoc review of the FX-322-202 trial found: • Inflation of hearing deficits at screen • Subjects under-reported the number of words they could understand from the word recognition test in order to achieve study eligibility. • Open communication about eligibility criteria • Some clinical trial site staff shared with subjects the reasons that they were excluded from the trial. • Frequency vocally communicated the requisite hearing deficits necessary to enter the trial and the intended primary endpoint. • Social media • Some subjects shared their information on social media platforms that are routinely used by subjects with hearing loss. 62

Experience Informs the Next Study: FX-322-208 Best Practices to Optimize Trial Outcome and Mitigate the Placebo Response • A protocol that blinds the key eligibility metric criteria from both staff and subjects (masking) and employs multiple hearing assessment measures • Blinding mitigates the risk of intentional inflation of hearing loss deficits • Multiple measures distract subjects from the “true” eligibility criteria • Blinding mitigates the risk of site staff sharing specifics about the study • Employ a protocol addendum for the masked criteria • FX-322-208 Unmasked Addendum is not seen by the trial site • Add an interim visit to assess symptom stability • Add rater training and site-independent monitoring as quality assurance layers to assure ratings precision 63

Our Path Forward David L. Lucchino Chief Executive Officer © © Fre Frequenc quency y Th Thera erapeuti peutics, cs, Inc. Inc. | | 93 93

Our Path Forward We believe FX-322 restores hearing. We know characteristics of FX-322 responders. Learnings from previous trials informed new trial design with strong controls and FDA approved clinical endpoints. We have a compelling new hearing program that will allow us to explore the impact of going deeper into the cochlea. We also have an exciting remyelination program in multiple sclerosis with a novel target and a strong response in vivo. We are a well capitalized company with resources to deliver innovation for patients and value for investors. © Frequency Therapeutics, Inc. | 94
