"We are very pleased to share intriguing new non-clinical data that suggest there is immune-suppressive cross-talk between IL-27 and PD-L1 expression within the tumor microenvironment," said Vito Palombella, PhD, Chief Scientific Officer, Surface Oncology. "Immunohistochemical analysis of IL-27, the IL-27 receptor, and PD-L1 shows co-localization across several cancer types, and in vitro studies have shown that IL-27 can directly upregulate PD-L1 expression on both immune and tumor cells. These data support our ongoing clinical studies evaluating SRF388, our first-in-class, fully human anti-IL-27 antibody, in combination with pembrolizumab."

Dr. Palombella added, "We also are pleased to share new SRF114 data which demonstrate the antibody’s ability to selectively deplete tumor Treg cells. We believe the selective depletion of intratumoral Treg cells provides a mechanism to inhibit tumor growth independent of checkpoint inhibition, as we have shown in our preclinical models. We look forward to investigating the safety and efficacy of SRF114 in a Phase 1 clinical trial."

SITC Poster Presentations:

Title: IL-27 expressed in the tumor microenvironment is correlated with PD-L1 levels and can induce PD-L1 expression on immune and tumor cells
Poster/Abstract: 1082
Session Type/Title: Immune-stimulants and immune-modulators
Session Date and Time: Friday, November 11 from 9 a.m.– 8:30 p.m.

Summary of key data:

Primary tumor samples from several cancers including lung, liver, renal, gastric, and head and neck, have IL-27+ tumor associated macrophages (TAMs).
IL-27-expressing TAMs are localized within the vicinity of PD-L1+ tumor cells in lung and liver cancers, with the highest IL-27+ density being associated with the highest PD-L1 expression.
IL-27 can regulate PD-L1 expression in immune cells and tumor cell lines.
Title: SRF114, an afucosylated anti-CCR8 antibody, depletes intratumoral Treg cells and reduces tumor growth
Abstract/Poster: 1388
Session Type/Title: Novel Single-Agent Immunotherapies
Session Date and Time: Friday, November 11 from 9 a.m.– 8:30 p.m.

Summary of key data:

CCR8 expression is highest on intratumoral regulatory T (Treg) cells compared to peripheral Tregs and other immune cells.
SRF114 treatment results in dose-dependent activation of immune cells, including natural killer (NK) cells and monocytes.
In dissociated tumor cultures, SRF114 selectively depletes Treg cells and has limited impact on effector T cells; in a mouse model, SRF114 treatment significantly reduces tumor growth and depletes intratumoral Treg cells, with minimal impact on peripheral Tregs.
The posters will be available on Surface Oncology’s website on November 10, 2022.

About SRF388
SRF388 is a fully human anti-IL-27 antibody designed to inhibit the activity of this immunosuppressive cytokine. Surface Oncology has identified particular tumor types, including liver and lung cancer, where IL-27 appears to play an important role in the immunosuppressive tumor microenvironment and may contribute to resistance to treatment with checkpoint inhibitors. SRF388 targets the rate-limiting p28 subunit of IL-27, and preclinical studies have shown that treatment with SRF388 blocks the immunosuppressive biologic effects of IL-27, resulting in immune cell activation in combination with other cancer therapies including anti-PD-1 therapy, as well as potent anti-tumor effects as a monotherapy. Furthermore, Surface Oncology has identified a potential biomarker associated with IL-27 that may be useful in helping to identify patients most likely to respond to SRF388. In November 2020, Surface announced that SRF388 was granted Orphan Drug designation and Fast Track designation for the treatment of refractory hepatocellular carcinoma from the FDA.

About SRF114
SRF114 is a fully human, afucosylated anti-CCR8 antibody designed to preferentially deplete CCR8+ Treg cells within the tumor microenvironment. In pre-clinical studies, Surface Oncology has shown that SRF114 induces antibody-dependent cellular cytotoxicity (ADCC) and/or antibody-dependent cellular phagocytosis (ADCP) pathways to deplete intratumoral Treg cells. In addition, SRF114 reduced tumor growth in murine models. These findings support the advancement of SRF114 as a therapeutic candidate that holds the potential to drive anti-tumor immunity in patients.

"The company continues advancing its portfolio of groundbreaking RAS(ON) Inhibitors aimed at tumors caused by altered RAS proteins, the most frequent genetic drivers of human cancer," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "In June, we initiated a Phase 1/1b trial evaluating RMC-6236 as monotherapy in patients with advanced solid tumors driven by various of the most common RAS mutations. Our team also initiated a Phase 1/1b trial evaluating RMC-6291, our first mutant-selective RAS(ON) Inhibitor, as monotherapy in patients with advanced solid tumors harboring the KRASG12C mutation in particular. We also continue advancing RMC-9805, a RAS(ON) Inhibitor candidate designed to target cancers driven by the KRASG12D mutation. We believe that these remarkable product candidates offer great potential for serving significant unmet medical needs.

"In addition, preliminary data disclosed by Amgen show the therapeutic combination of RMC-4630 and sotorasib is safe and tolerable and offered encouraging initial evidence of promising and durable clinical activity in patients with non-small cell lung cancer (NSCLC) bearing a KRASG12C mutation. Revolution Medicines is sponsoring an ongoing Phase 2 study evaluating the RMC-4630 and sotorasib combination that is intended to test further the potential for additive clinic benefit. We look forward to the results from this study and from the ongoing Phase 1/1b study of RMC-5552, our mTORC1/4EPB1 inhibitor, as we evaluate these important RAS Companion Inhibitors.

"Finally, in July 2022, we completed a public equity financing raising gross proceeds of approximately $265 million that strengthened our overall financial position to support the continued expansion and advancement of our clinical portfolio with assets from our highly productive discovery and preclinical efforts."

Clinical and Development Highlights

RAS(ON) Inhibitors

RMC-6236 (RASMULTI)

RMC-6236 is an oral RAS(ON) Inhibitor designed to treat patients with cancers driven by a variety of RAS mutations, including KRASG12D, KRASG12V and KRASG12R. Initially being evaluated as monotherapy, it may also be deployed as a RAS Companion Inhibitor in combination with mutant-selective RAS(ON) Inhibitors.

The ongoing Phase 1/1b monotherapy trial (NCT05379985) is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6236 in patients with advanced solid tumors harboring select KRASG12 mutations, including KRASG12D, KRASG12V and KRASG12R. To the company’s knowledge, RMC-6236 is the first oral, direct RAS inhibitor to be deployed against a tumor harboring any of these RAS cancer drivers. The company currently expects to provide evidence of first-in-class single agent activity for RMC-6236 in 2023.
RMC-6291 (KRASG12C)

RMC-6291, an oral, selective, covalent inhibitor of KRASG12C(ON) designed to treat patients with cancers driven by the KRASG12C mutant, is the first of the company’s mutant-selective RAS(ON) Inhibitors to enter clinical development and the first publicly reported inhibitor of KRASG12C that exhibits a highly differentiated mechanism of action.

The ongoing Phase 1/1b monotherapy trial (NCT05462717) is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6291 in patients with advanced KRASG12C-mutant solid tumors. The company currently expects to provide preliminary evidence of superior activity for this compound in 2023.
RMC-9805 (KRASG12D)

RMC-9805 is an oral, selective, covalent inhibitor of KRASG12D(ON), the most common driver of RAS-addicted human cancers, predominantly among patients with pancreatic cancer, NSCLC or colorectal cancer (CRC). The company believes RMC-9805 is the first oral and covalent inhibitor of KRASG12D.

The company currently expects to announce dosing of the first patient in a monotherapy dose-escalation study of RMC-9805 in mid-2023.
RAS Innovation Engine

Beyond this first wave of RAS(ON) Inhibitors, the company continues expanding its pipeline of RAS(ON) Inhibitor candidates.

RMC-8839 is a potent, oral and selective development-stage tri-complex inhibitor of KRASG13C(ON). The company believes RMC-8839 is the first compound to directly inhibit KRASG13C, an important therapeutic target primarily for NSCLC and select CRC patients unserved by a targeted RAS inhibitor.
The company continues drug discovery efforts in RAS(ON) Inhibitor pipeline expansion programs focused on RAS mutation hotspots including KRASG12R, KRASG12V, KRASG13D, KRASQ61X, and other important targets.
The company currently expects to nominate a fifth RAS(ON) Inhibitor development candidate in the second half of 2022.
RAS Companion Inhibitors

RMC-4630 (SHP2)

RMC-4630 is a clinical-stage, oral inhibitor of SHP2, which contributes to tumor survival and growth in many RAS-addicted cancers. RMC-4630 (also known as SAR442720) continues development under the company’s global SHP2 development and commercialization partnership with Sanofi.

RMC-4630 and KRASG12C Inhibitor Lumakras (sotorasib)

CodeBreaK 101c: Amgen’s CodeBreaK 101c study is an exploratory Phase 1b trial evaluating the combination of RMC-4630 with the KRASG12C inhibitor sotorasib in patients with advanced KRASG12C-mutated solid tumors. In August 2022, Amgen reported preliminary results from this trial at the IASLC 2022 World Conference on Lung Cancer. These results demonstrated that the combination was safe and tolerable, and showed promising early clinical activity in NSCLC patients with KRASG12C mutations, particularly in patients who were KRASG12C inhibitor-naïve.
RMC-4630-03: Revolution Medicines continues enrolling patients in its global Phase 2 trial RMC-4630-03 (NCT05054725), a multicenter, open-label study of RMC-4630 in combination with sotorasib for patients with NSCLC with a KRASG12C mutation who have failed prior standard therapy and who have not previously been treated with a KRASG12C inhibitor. The company is sponsoring the RMC-4630-03 study under its global SHP2 partnership with Sanofi and conducting the trial in collaboration with Amgen, which is supplying sotorasib to trial sites globally. Revolution Medicines currently expects to provide topline data from this study in the second half of 2023.
RMC-4630 and KRASG12C Inhibitor adagrasib

Sanofi is recruiting patients in a Phase 1/2 dose escalation and expansion study under its SHP2 partnership with Revolution Medicines, and in collaboration with Mirati. The study will evaluate RMC-4630 in combination with adagrasib (MRTX849) in patients with previously treated NSCLC bearing a KRASG12C mutation.

RMC-4630 and PD-1 Inhibitor KEYTRUDA (pembrolizumab)

Sanofi is conducting a Phase 1 trial evaluating RMC-4630 in combination with pembrolizumab, a PD-1 inhibitor, as first-line treatment for patients with PDL-1 positive NSCLC.
RMC-5552 (mTORC1/4EPB1)

RMC-5552 is a first-in-class, bi-steric mTORC1-selective inhibitor designed to suppress phosphorylation and inactivation of 4EBP1 in cancers with hyperactive mTORC1 signaling, including certain RAS-addicted cancers. The company aims to combine RMC-5552 with RAS(ON) Inhibitors in patients with cancers harboring RAS/mTOR pathway co-mutations.

Dose optimization continues in the company’s ongoing multicenter, open-label, Phase 1/1b dose-escalation study evaluating RMC-5552 monotherapy in patients with refractory solid tumors (NCT04774952). This study is expected to enable combination studies in RAS-addicted cancers.
The company currently anticipates disclosing additional evidence of single agent activity for this compound in 2023.
Corporate Highlights

Financing

In July 2022, the company completed an upsized public offering of common stock, raising gross proceeds of $264.5 million before deducting underwriting discounts, commissions and offering expenses. This included the exercise in full by the underwriters of their option to purchase additional shares of common stock. These funds will be used to strengthen the company’s balance sheet and overall financial position to support the continued development and expansion of its product pipeline.

Management Appointments

During the third quarter of 2022, the company strengthened its senior leadership with the promotions of Jack Anders, who previously served as the company’s senior vice president, finance and principal financial and accounting officer, to the position of chief financial officer, and Jeff Cislini, formerly vice president, deputy general counsel, to the position of senior vice president, general counsel and corporate secretary. In addition, Daniel Simon, former senior vice president, biopharma business development at Guardant Health, joined the company in the newly created position of chief business officer.

Third Quarter 2022 Financial Highlights

Cash Position: Cash, cash equivalents and marketable securities were $655.0 million as of September 30, 2022, compared to $577.1 million as of December 31, 2021. The increase was primarily attributable to the company’s public equity offering in July 2022.

Revenue: Total revenue was $3.4 million for the quarter ended September 30, 2022, and consisted of revenue from the company’s collaboration agreement with Sanofi. During the quarter ended September 30, 2022, the company recorded a non-cash GAAP accounting adjustment that reduced collaboration revenue by $4.6 million. This non-cash revenue adjustment was due to changes to the company’s estimates of the accounting transaction price and estimated percentage of completion of work performed to date under the Sanofi collaboration agreement, and resulted in a cumulative catch-up adjustment to collaboration revenue in the quarter.

Total revenue for the quarter ended September 30, 2021, was $1.1 million and included a similar non-cash GAAP accounting adjustment resulting from changes in estimates that reduced collaboration revenue by $8.5 million.

R&D Expenses: Research and development expenses were $69.5 million for the quarter ended September 30, 2022, compared to $46.5 million for the quarter ended September 30, 2021. The increase was primarily due to an increase in RMC-6236 and RMC-6291 expenses as a result of commencing clinical trials, an increase in personnel-related expenses related to additional headcount, an increase in research expenses associated with the company’s pre-clinical research portfolio, and an increase in stock-based compensation.

G&A Expenses: General and administrative expenses were $10.4 million for the quarter ended September 30, 2022, compared to $7.8 million for the quarter ended September 30, 2021. The increase was primarily due to an increase in stock-based compensation and an increase in personnel-related expenses related to additional headcount.

Net Loss: Net loss was $73.3 million for the quarter ended September 30, 2022, compared to net loss of $52.9 million for the quarter ended September 30, 2021.

2022 Financial Guidance

Revolution Medicines is reiterating its projected full year 2022 GAAP net loss to be between $260 million and $280 million, including estimated non-cash stock-based compensation expense of $30 million to $35 million. With current cash, cash equivalents and marketable securities, the company currently projects it can fund planned operations through 2024.

Dror Ben-Asher, RedHill’s Chief Executive Officer, said: "Quarter two, and our expectations for the second half of the year, reflect significant operational and strategic progress by RedHill in the face of persistent negative biotech sector sentiment. Our commercial team is streamlined, with much reduced operational spend, and continues to rapidly grow new prescriptions. It is this growth, at this stage in its lifecycle, that is making Movantik such a valuable and saleable asset, and which has led Talicia to be the most prescribed branded agent by the Gastroenterology community, on track to become the most prescribed branded H. pylori therapy in 2023. With increased gross sales, we are applying substantial efforts to improving gross-to-net yields, using multiple parallel mechanisms. We are fully committed to refining our pre-pandemic debt structure in a way that helps us rapidly grow our business both organically and externally, through the intended sale of Movantik and the planned addition of new revenue-generating products currently under discussions. We continue to work relentlessly to maximize the value of our products and optimize our business. As such, the cost-reduction program we implemented is expected to deliver its major impact in the second half of the year."

Mr. Ben-Asher continued: "With an urgent need to develop broad-spectrum, host-directed antivirals for pandemic preparedness, RedHill is driving forward its opaganib and RHB-107 COVID-19 and other antiviral programs. We are currently in advanced discussions regarding external non-dilutive development funding for RHB-107 and are in the process of finalizing RHB-107’s inclusion in a key platform study to be supported by a U.S. government arm. Both opaganib and RHB-107 continue to demonstrate the variant-agnostic value of being host-directed, demonstrating in vitro inhibition of the Omicron BA.5 sub-variant in testing conducted at the University of Tennessee. We are also delighted with the grant of a new COVID-19 treatment patent for opaganib. Beyond COVID-19, we have established several cooperative research projects, with both government and non-government entities, to evaluate opaganib and RHB-107 across multiple targets, including influenza, which opaganib recently demonstrated in vitro efficacy against, Ebola, and others. We are also pleased with the important recognition of EU Orphan Designation for RHB-204, currently in Phase 3 study as the first stand-alone standard of care first-line therapy for NTM disease, and for which prospective partnership discussions are advancing across multiple territories."

Financial results for the six months ended June 30, 2022 (Unaudited)4

All financial highlights are approximate and are rounded to the nearest hundreds of thousands. The comparisons in this section reflect the restated condensed consolidated interim financial statements as of and for the three months ended March 31, 2022, described below.

Net Revenues for the six months ended June 30, 2022, were $31.5 million, as compared to $42.1 million for the six months ended June 30, 2021. The increase in units sold in the six months ended June 30, 2022, as compared to the six months ended June 30, 2021, was accompanied by increased gross-to-net allowances as the percentage of Medicare part D and Medicaid prescriptions increased.

The Company has restated its condensed consolidated interim financial statements as of and for the three months ended March 31, 2022, due to errors in the calculation of allowance for deductions from revenue. Cost of revenues, gross profit and operating loss were adjusted accordingly. This does not affect any other accounting period and is unlikely to impact the full-year outlook.

Cost of Revenues for the six months ended June 30, 2022, was $15.3 million, as compared to $20.8 million for the six months ended June 30, 2021.

Gross Profit for the six months ended June 30, 2022, was $16.2 million, as compared to $21.2 million for the six months ended June 30, 2021. The decrease was primarily attributed to the impact of increased gross-to-net allowances outlined above.

Operating Loss for the six months ended June 30, 2022, was $25.8 million, as compared to $43 million for the six months ended June 30, 2021. The decrease was primarily attributed to reductions in operating expenses.

Net Cash Used in Operating Activities for the six months ended June 30, 2022, was $20.7 million, as compared to $31.2 million for the six months ended June 30, 2021. The decrease was attributed to the completion of components of the opaganib and RHB-107 development programs as well as various cost reduction measures.

Restated financial results for the three months ended March 31, 2022 (Unaudited)5

The Company has restated its condensed consolidated interim financial statements as of and for the three months ended March 31, 2022, due to errors in the calculation of allowance for deductions from revenue which resulted in net revenues being overstated. Cost of revenues, gross profit and operating

All financial highlights are approximate and are rounded to the nearest hundreds of thousands.

loss were adjusted accordingly. This does not affect any other accounting period and is unlikely to impact the full-year outlook. The comparison below reflects this restatement.

Net Revenues for the first quarter of 2022 were $13.1 million, as compared to $22.1 million in the fourth quarter of 2021, the difference being attributable to typical cyclical trends in Movantik sales and increased gross-to-net deductions related mainly to increased formulary coverage.

Cost of Revenues for the first quarter of 2022 was $6.3 million, as compared to $19.3 million in the fourth quarter of 2021. The decrease was attributed to recognition of an approximately $9 million impairment related to the intangible asset of Aemcolo for travelers’ diarrhea in the fourth quarter of 2021.

Gross Profit for the first quarter of 2022 was $6.8 million, as compared to $2.7 million in the fourth quarter of 2021. The increase was attributed to the impairment recognized in the fourth quarter of 2021, as detailed above.

Research and Development Expenses for the first quarter of 2022 were $3.1 million, as compared to $5.9 million in the fourth quarter of 2021. The decrease was attributed to the ongoing optimization of R&D costs and completion of elements of the opaganib and RHB-107 development programs.

Selling, Marketing and General and Administrative Expenses for the first quarter of 2022 were $20.4 million, as compared to $17.6 million in the fourth quarter of 2021. The increase was mainly attributed to a one-off positive adjustment in the fourth quarter of 2021 and expenses related to professional services and other related expenses in the first quarter of 2022.

Operating Loss for the first quarter of 2022 was $16.6 million, as compared to $20.7 million in the fourth quarter of 2021. The decrease was mainly attributed to the impairment recognized in the previous quarter, as detailed above.

Net Cash Used in Operating Activities for the first quarter of 2022 was $4.2 million, as compared to $14.9 million in the fourth quarter of 2021. The decrease was mainly due to changes in working capital and continued implementation of cost-reduction measures.

Net Cash Used in Financing Activities for the first quarter of 2022 was $4.9 million, as compared to Net Cash Provided by Financing Activities of $17.6 million in the fourth quarter of 2021, comprised mostly from proceeds of equity offerings completed in the fourth quarter of 2021. The additional decrease of $5 million was due to a reduction of Movantik acquisition liabilities.

With respect to the Q1/22 restatement, the Company determined that a material weakness existed within its internal control over financial reporting as it related to recognition of certain allowances for deductions from revenues. Management, with the oversight of the audit committee and external advisors, has implemented additional processes and controls with respect to recognition of certain allowances for deduction from revenues to address this deficiency.

Liquidity and Capital Resources

Cash Balance1 as of June 30, 2022, was $43.2 million, as compared to $45 million as of March 31, 2022, and $54.2 million as of December 31, 2021.

On May 9, 2022, the Company announced that it had entered into a definitive agreement with a single leading healthcare investor for the purchase and sale of 10,563,380 of the Company’s American Depositary Shares ("ADSs") (or ADS equivalents) in a registered direct offering at a price per ADS of $1.42. The gross proceeds to the Company from this offering were approximately $15 million, before fees and expenses. RedHill also agreed to issue to the investor unregistered private warrants to purchase up to an aggregate of 13,204,225 ADSs in a concurrent private placement. The warrants have an exercise price of $1.48 per ADS, are exercisable six months after the issuance date and have a term of five and one-half years.

On June 17, 2022, the Company and HCR entered into an amendment to the HCR Credit Agreement reducing the minimum net sales requirement to $75.0 million for the trailing four quarter periods ending on June 30, 2022, and September 30, 2022, with a 0.5% increase in interest rate in these quarters. Redhill Inc. shall also be required to maintain minimum net sales of $14 million for Movantik each fiscal quarter starting the fiscal quarter ending June 30, 2022.

On September 13, 2022, the Company received a notice from HCR asserting certain events of default under the Credit Agreement, resulting in the outstanding obligations under the Credit Agreement now bearing interest at the default rate under the Credit Agreement. The Company disagrees with the assertions made by HCR and is engaged with HCR in good faith in order to establish a consensual business resolution to this dispute. RedHill continues operating its business as usual, while also concurrently evaluating strategic alternatives to satisfy its outstanding obligations under the Credit Agreement through the potential sale of Movantik.

In addition to the previously reported breach of the 60 days quarterly reporting covenant in connection with the second quarter financial statements, the possibility of also being in default of the $75.0 million net sales covenant for the trailing four fiscal quarter period ending on September 30, 2022, remains. We are working with our creditor toward an agreement on constructive solutions and repayment of debt, including the potential sale of Movantik in order to satisfy the outstanding loan obligations.

On November 3, 2022, the Company received a termination notice from SVB Securities LLC ("SVB Securities"), with respect to itself, in connection with the Sales Agreement dated July 29, 2022, by and among the Company, SVB Securities and Cantor Fitzgerald & Co.

On September 2, 2022, the Company filed a lawsuit against Kukbo Co. Ltd. ("Kukbo") in the Supreme Court of the State of New York, County of New York, Commercial Division, as a result of Kukbo’s default in delivering to the Company $5.0 million under the Subscription Agreement, dated October 25, 2021, in exchange for ADSs, and a further payment of $1.5 million due under the Exclusive License Agreement, dated March 14, 2022. Kukbo has not raised counter-arguments and we believe a

favorable judgement is expected within weeks, strengthening the balance sheet significantly if collected.

Discussions regarding the potential sale of Movantik, RHB-204 out-licensing in multiple territories and the in-licensing of a new revenue-generating GI product are advancing.

Quarter Three, 2022, Estimates:

Based on unaudited and preliminary estimates, total net revenues for the quarter ended September 30, 2022, were in the range of $16.5 million to $18.5 million.

The Company further estimates that its operating loss for the quarter ended September 30, 2022, was in the range of $5.5 million to $7.5 million.

The Company’s current estimate for Q3/22 cash flow from operating activities is approximately $6.7 million and positive for U.S operations3.

As of September 30, 2022, RedHill’s cash, short-term investments and restricted cash were approximately $31.4 million, compared to $54.2 million as of December 31, 2021.

The above-estimated revenue and operating loss figures for the quarter ended September 30, 2022, reflect RedHill’s current preliminary review, which is still ongoing and could result in changes to the estimated revenues and operating loss figures. These estimates were not reviewed by our independent accountants.

Commercial Highlights

Movantik (naloxegol)6

●Movantik delivered a 4% growth in new prescriptions in Q2/22, compared to Q1/22, representing the highest quarterly prescribing volume for Movantik since RedHill acquired the product rights
●Movantik continues to hold a firm grip on its PAMORA class leadership position, with more than 70% market share. As market leader, Movantik is anticipated to benefit further from positive PAMORA class growth trends – up 7% for the three months ending August 2022 as compared to the same period in the previous year
●Two new Movantik analyses, from pooled data from two Phase 3 studies, were presented at PAINWeek in September, demonstrating that Movantik (naloxegol) provides healthcare-related quality of life (HR-QOL) and clinically meaningful symptom improvements, compared to placebo, in patients with opioid-induced constipation (OIC)

Movantik (naloxegol) is indicated for opioid-induced constipation (OIC). Full prescribing information see: www.movantik.com.

●Movantik retains best-in-class coverage with Preferred Status in two of the three largest Commercial PBMs and 92% Preferred Status within Medicare Part D7
●New updated Centers for Disease Control and Prevention (CDC) guidelines, issued November 2022, provided for increased flexibility in opioid prescribing

Talicia (omeprazole magnesium, amoxicillin and rifabutin)8

●An 11.2% increase in Talicia prescriptions in Q2/22, compared to Q1/22, builds on the record quarterly prescription levels seen in Q1/22 and Q4/21 and represents 86.4% growth in Talicia prescriptions compared to Q2/21
●Talicia is the most prescribed branded agent by the Gastroenterology community and is on track to become the most prescribed branded H. pylori therapy in 2023.
●New Talicia data analyses were presented at Obesity Week (November 2022) and the World Gastro 2022 congress (August 2022) support the efficacy and safety of Talicia as empiric first-line treatment for H. pylori infection in patients regardless of obesity, body mass index (BMI) or diabetic status and demonstrating that:
oTalicia’s efficacy in the pooled data from two Phase 3 studies was unaffected by presence of diabetes, obesity or BMI
oIntragastric rifabutin exposure was unaffected by patient BMI, and that Talicia provides favorable intragastric rifabutin concentrations compared to generically available rifabutin
oThe safety profile of Talicia in these patients was generally similar to the overall population and no cases of hypoglycemia were reported. This is clinically relevant as clarithromycin has a risk of drug interactions with commonly used diabetes medications such as insulin and metformin, as well as potential for increased risk of hypoglycemia
●The addition of Florida Medicaid unrestricted preferred coverage increased Medicaid coverage of Talicia by 4.9% to 23%. An additional 1.9 million lives gained coverage in May 2022. A commercial PBM win improved coverage to "preferred" for an additional 58.0 million lives starting July 1, 2022. As of August 2022, total Talicia coverage stood at almost 200 million American lives, equating to seven out of ten commercial lives and six out of ten Government lives

Aemcolo (rifamycin)9

●The first post-pandemic prescriptions for Aemcolo are beginning to be seen and the Company is planning additional commercialization initiatives focused on driving growth in the primary care segment

Opaganib (ABC294640)10 & RHB-107 (upamostat)11 – COVID-19, variants and other viruses

●With an urgent need to develop broad-spectrum, host-directed antivirals for pandemic preparedness, RedHill is:
oCurrently in late-stage discussions regarding funding for a pivotal Phase 3 study for RHB-107 and close to finalizing inclusion in a key platform study
oWorking on several cooperative projects, with government and non-government bodies, on a range of preclinical studies with opaganib and RHB-107 (upamostat) against multiple viral targets, including influenza and Ebola (amongst others)
●Both once-daily RHB-107 (upamostat) and twice-daily opaganib demonstrated in vitro inhibition of Omicron BA.5 sub-variant in testing conducted by the University of Tennessee in October 2022
●The United States Patent and Trademark Office (USPTO), in October 2022, granted a new method of use patent for opaganib for the inhibition of a disease caused by a coronavirus in patients having pneumonia and receiving supplemental oxygen at a fraction of inspired oxygen (FiO2) up to and including 60%
●In July 2022, opaganib’s suggested host-directed mechanism of action was published in the journal Drug Design, Development and Therapy, describing opaganib’s multi-faceted potential to: inhibit multiple pathways, induce autophagy and apoptosis, and disrupt the viral RTC (replication-transcription complex) through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SK2, DES1 and GCS)
●In June 2022, opaganib demonstrated potent in vitro inhibition of influenza A H1N1, at low concentrations and with no evidence of toxicity at these levels in a Normal Human Bronchial Epithelial Cells (NHBE) assay, the natural human target of the virus, making it a realistic model

RHB-204 – Pulmonary Nontuberculous Mycobacteria (NTM) Disease12

●In August 2022, the European Commission granted Orphan Drug Designation to RHB-204, which is in an ongoing U.S. Phase 3 study, for the treatment of nontuberculous mycobacteria (NTM) disease, providing 10 years of post-approval EU market exclusivity
●The Company is advancing discussions with prospective partners for RHB-204 across multiple territories including the EU and others.
