GH Research Reports Full Year 2022 Financial Results and Provides Business Updates

DUBLIN, Ireland., March 2, 2023 (GLOBE NEWSWIRE) -- GH Research PLC (Nasdaq: GHRS), a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and

neurological disorders, today reported financial results for the full year ended December 31, 2022 and gave updates on its business.

We are pleased to report that we have recently initiated our multi-center, randomized, double-blind, placebo-controlled Phase 2b trial of GH001 in treatment-resistant depression (TRD)

(GH001-TRD-201). GH001 is our proprietary inhalable mebufotenin (5-MeO-DMT) product candidate.

We expect to recruit approximately 80 patients for this trial across several European countries. The primary objective will be to determine the efficacy of our single-day individualized dosing regimen

(IDR) of GH001 compared with placebo in improving depressive symptoms as assessed by the mean change from baseline in Montgomery- sberg Depression Rating Scale (MADRS) at the end of the 7-day double-blind phase. The double-blind phase will be

followed by a 6-month open-label extension phase where all patients can receive treatment with the GH001 IDR as-needed, based on the patient's clinical status. Further trial design details are described in our updated corporate presentation,

which is available in the investor section on our website.

Recent Business Highlights

In January 2023, we reported development progress in respect of our proprietary aerosol delivery device and our expectation that we will submit an IND for GH001, delivered with this proprietary

device, in the third quarter of 2023. The IND-opening study is expected to be a Phase 1 clinical pharmacology trial in healthy volunteers (GH001-HV-106), designed to support bridging to the clinical data generated with the third-party device we

currently use in our clinical trials.

We also reported, in January 2023, the recent initiation of our randomized, double-blind, placebo-controlled, dose-ranging clinical pharmacology trial of GH002 in healthy volunteers

(GH002-HV-105). GH002 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intravenous approach. We expect to complete this trial in the fourth quarter of 2023.

Furthermore, we reported the recent expansion of our patent portfolio, to include 11 patent families that relate to various aspects of mebufotenin (5-MeO-DMT) use in a therapeutic context,

including but not limited to the use of mebufotenin (5-MeO-DMT) for treatment of various disorders when administered by inhalation, or by nasal, buccal, sublingual, intravenous, intramuscular or subcutaneous routes.

We also announced the selection of mebufotenin as the International Nonproprietary Name (INN) for 5-MeO-DMT by the World Health Organization (WHO) Expert Advisory Panel on the International

Pharmacopoeia and Pharmaceutical Preparations.

Full Year 2022 Financial Highlights

Cash, cash equivalents and marketable securities were $251.7 million as of December 31, 2022, compared to cash of $276.8 million as of December 31, 2021. Marketable securities are

comprised of investment grade bonds. We believe that our existing cash, cash equivalents and marketable securities will be sufficient for us to fund our operating expenses and capital expenditure requirements into 2026.

Research and development expenses

R&D expenses were $20.5 million for the year ended December 31, 2022, compared to $8.6 million for the full year 2021. The increase was primarily due to increased activities relating to our

technical development, clinical trials and increased employee expenses to support these activities.

General and administrative expenses

G&A expenses were $10.1 million for the year ended December 31, 2022, compared to $6.5 million for the full year 2021. The increase was primarily due to higher insurance costs, an increase

in professional costs as well as increased employee expenses.

Net loss was $22.5 million, or $0.432 loss per share, for the year ended December 31, 2022, compared to $9.2 million, or $0.211 loss per share, for the full year 2021.

About GH Research PLC

GH Research PLC is a clinical-stage biopharmaceutical company dedicated to transforming the treatment of psychiatric and neurological disorders. GH Research PLC's initial focus is on developing

its novel and proprietary mebufotenin (5-MeO-DMT) therapies for the treatment of patients with treatment-resistant depression (TRD).

Our lead product candidate, GH001, is formulated for mebufotenin (5-MeO-DMT) administration via a proprietary inhalation approach. With GH001, we have completed two Phase 1 healthy volunteer

clinical trials and a Phase 1/2 clinical trial in patients with treatment-resistant depression (TRD). Based on the observed clinical activity, where 87.5% of patients with TRD were brought into an ultra-rapid remission with our GH001

individualized single-day dosing regimen in the Phase 2 part of the trial, we believe that GH001 has potential to change the way TRD is treated today. GH001 is currently in a multi-center, randomized, double-blind, placebo-controlled Phase 2b

trial of GH001 in treatment-resistant depression (TRD). Across the GH001 program, no serious adverse events have been reported and GH001 was well tolerated at the investigated single dose levels and in the individualized dosing regimen.

About GH002 and GH003

GH002 is our mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intravenous approach. GH002 is currently in Phase 1 clinical development. GH003 is our

mebufotenin (5-MeO-DMT) product candidate formulated for administration via a proprietary intranasal administration approach. GH003 is currently in preclinical development. We anticipate developing GH002 and GH003 in subpopulations and confined

use scenarios within our focus area of psychiatric and neurological disorders.
