Background 3 Inarigivir ( IRIG ) is being developed as an oral immunomodulatory backbone agent for combination strategies to achieve HBV Functional Cure Achievement of “Functional Cure” in HBV requires: Loss of HBsAg or sustained suppression of HBV DNA off all treatment after a finite duration of therapy Safety and tolerability profile similar to NUCs Immune control of cccDNA / HBV replication - critical for achieving a sustained response

4 Inarigivir Acts Through Modulation of the Innate Immune System Involving RIG-I Novel mechanism of action Actively transported into hepatocytes via OATP-1 and OAT-1 with 30:1 liver to plasma ratio Binds to RIG-I and causes induction of IFN signaling Demonstrated activation of immune system in HCV patients and healthy volunteers at 400mg daily DAA effect to prevent interaction of HBV Pol and pgRNA in cell systems Active against polymerase and capsid resistant strains Activates “host” targets instead of viral targets – potential for higher barrier to viral resistance RIG-I is a sentinel protein involved in the body’s innate defense system

Healthy Volunteers Trial Design 5 Inarigivir 400 mg /Daily 12 days: 14 healthy volunteers Day 1 Day 12 11 Days 400 mg Samples Cytokines in sera (IFN-a, IP-10, TNF-a, IFN-g, IL-6, IL-12p70) PBMC for flow cytometry analysis (T, NK, myeloid cells activation) PBMC for Nanostring analysis 0 4h 12h 0 2h 24h 6h Inarigivir, a RIG-I agonist, activates innate immunity in healthy volunteers.

Exhibit 99.2

Spring Bank Announces Positive Results from the Recently Completed Phase 2 Chronic Hepatitis B ACHIEVE Trial and Additional Inarigivir Studies

Consistent reduction in HBV DNA demonstrated with higher inarigivir doses including in high viral burden HBeAg-positive patients

26% HBsAg responder population for all inarigivir doses showed mean HBsAg change of 0.8log₁₀ with a range of 0.5log₁₀ - 1.4log₁₀

Inarigivir 400mg rapidly and uniformly increased activation markers of innate immunity without evidence of tolerance in a new inarigivir study in healthy volunteers

Favorable safety and tolerability profile observed across all doses studied

Conference call to be held today, April 12 at 8:00am EDT

HOPKINTON, Mass., Apr. 12, 2019 – Spring Bank Pharmaceuticals, Inc. (Nasdaq: SBPH), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of viral infections, inflammatory diseases and certain cancers, today announced at The International Liver Congress™ (ILC), the 2019 Annual Meeting of the European Association for the Study of the Liver (EASL) in Vienna, Austria, robust results from the recently completed inarigivir Phase 2 dose escalation ACHIEVE trial for patients with chronic hepatitis B virus (HBV). Spring Bank is developing inarigivir, an orally-administered hepatic-selective immunomodulator, as a potential backbone in a combinatorial treatment for chronic HBV with the goal to accelerate and substantially increase chronic HBV functional cure rates in a simple, safe and selective manner.

In an oral presentation during the General Session II Award Ceremony I at the ILC earlier today, Professor M.F. Yuen, Chief of Gastroenterology and Hepatology, University of Hong Kong, and Principal Investigator for the ACHIEVE trial, presented top-line results from all cohorts including the final 200mg dosing cohort. The data show that inarigivir continued to demonstrate a dose-dependent effect on HBV DNA and HBV RNA in the fourth cohort of the ACHIEVE trial over the 12-week dosing period. Inarigivir 200mg monotherapy dosing exhibited a mean decrease of 1.54log₁₀ in HBV DNA with a range of 0.71log₁₀ to 3.26log₁₀ and a mean decrease of 1.14log₁₀ in HBV RNA with a range of 0.08log₁₀ to 4.88log₁₀. Inarigivir 200mg monotherapy showed a uniform antiviral response (HBV DNA) in all patients, in particular the high viral burden HBeAg-positive patients who had not responded to the lower doses of inarigivir monotherapy in the earlier ACHIEVE cohorts. In addition, across all patients HBV DNA and HBV RNA responses strongly correlated with baseline HBsAg, baseline IP-10 and the decline of IP-10 at week 12, comparable to the clinical experience with interferon in chronic HBV.

Across all four dosing cohorts, 16 of the 62 (26%) evaluable patients treated with inarigivir had a 0.5log₁₀ or greater reduction in HBsAg at week 12 or week 24 and were categorized as responders. The mean reduction of HBsAg in this responder population was 0.8log₁₀ with a range of 0.5log₁₀ to 1.4log₁₀. Importantly, the HBsAg response to inarigivir in the ACHIEVE trial was genotype and host dependent.  Although the number of patients was small, the HBsAg response seen in Genotype A and D was excellent with 4 of 5 patients responding. Genotype B and C were the most common genotypes and 33% of

1

 

genotype B responded compared to 10% of genotype C. It is important to note that 2 of the 3 genotype C patients that responded received200mg inarigivir dose and belonged to the higher viral burden HBeAg-positive group. This amplified HBsAg response observed with inarigivir in genotype B compared to genotype C is comparable to the clinical experience of the immunomodulator interferon in the treatment of chronic HBV.

The overall data from the ACHIEVE trial also revealed evidence of a significant shutdown of viral transcription by inarigivir in HBeAg-negative patients where HBV RNA was undetectable at week 12 in all patients treated with inarigivir at the 50mg, 100mg, and 200mg doses with a concomitant undetectable HBcrAg in the majority of these patients. At week 24, the HBV RNA and HBcrAg response was sustained with the switch to tenofovir disoproxil fumarate 300mg and associated with 18 of the 22 (82%) HBeAg-negative patients also having undetectable HBV DNA.

Inarigivir was shown to be well tolerated at all doses in the ACHIEVE trial. Treatment-emergent adverse events ranged from mild to moderate in severity, with no investigator determined interferon-like side effects. The percentage of treatment-emergent adverse effects reported in the ACHIEVE trial was similar between the active and placebo groups. In the fourth cohort, one Grade 3 event (hypertriglyceridemia) was observed, but was not sustained on retesting, and there was one serious adverse event (SAE) for knee pain hospitalization reported, but this patient was dosed with placebo. There were no other clinical or biochemical events above Grade 3 during the ACHIEVE trial.

“The data from the ACHIEVE trial demonstrate a clear dose dependent antiviral response on HBV DNA and HBV RNA with inarigivir treatment,” said Professor M.F. Yuen. “Importantly, inarigivir treatment of HBeAg- negative patients in this study suggests a rapid down-regulation of cccDNA transcription.” Professor Yuen continued, “The HBsAg response of a 0.5log₁₀ or greater reduction in the inarigivir-treated patients is the best reported to date with an oral agent in the treatment of chronic HBV patients, with a similar genotype distribution of responders to that reported for interferon, the only approved immunomodulator treatment for chronic HBV.”

Additional inarigivir data announced highlighting immune-activation with the 400mg dose

Spring Bank also announced today the results from a healthy volunteer study that examined the potential for the use of the 400mg dose of inarigivir in chronic HBV patients. The results from this study revealed that inarigivir 400mg rapidly and uniformly increased activation markers of innate immunity on circulating peripheral monocytes and dendritic cells which was sustained over a ten-day period of dosing without evidence of tolerance. There was an associated activation of CD8+ t-cells and down-regulation of NK cells resulting in a potentially favorable adaptive immune profile for an antiviral response. The results from this study also demonstrated a lack of systemic cytokine activation secondary to the intra-hepatic targeting of inarigivir resulting in a favorable tolerability profile. These compelling immune-activation data for inarigivir, together with the dose-dependent effects on HBV DNA and HBV RNA and favorable tolerability profile observed up to 200mg daily in the ACHIEVE trial, serve as the basis for the recent launch of the Spring Bank global CATALYST trials in both treatment-naïve and virally-suppressed chronic HBV patients. The CATALYST trials will focus on the examination of the 400mg dose of inarigivir.

“The increasing antiviral response seen at the 200mg dose, especially in high viral burden patients, and the clear evidence of innate immune activation at the 400mg dose in healthy volunteers with good

2

 

tolerability, has led Spring Bank to choose 400mg as the inarigivir dose to move forward into longer studies focused on HBV cure,” said Nezam Afdhal, M.D., D.Sc., chief medical officer of Spring Bank Pharmaceuticals. “We have developed a comprehensive strategic clinical trial program that takes into account both patient and viral heterogeneity that we anticipate will inform our Phase 3 strategy moving into 2020.”

EASL 2019 ILC Poster Presentation demonstrating antiviral activity of inarigivir in nucleoside- and capsid-resistant HBV variants

In a poster presentation at EASL 2019 ILC, Professor Stephen Locarnini, Head of Research & Molecular Development at the Victorian Infectious Diseases Reference Laboratory and Principal Investigator of the Virology Core for the ACHIEVE trial, described his in vitro study examining the antiviral activity of inarigivir in HBV clinical isolates consisting of capsid inhibitor (CpAM) and nucleoside (NUC) analog resistant variants. Looking forward to novel combinations with agents under investigation with differing mechanisms of action, Dr. Locarnini evaluated inarigivir in NUC- and CpAM-resistant clinical isolates from HBV patients. Professor Locarnini’s data indicate that inarigivir could be used as rescue or combination therapy for NUC/CpAM-resistant failures.

Professor Locarnini stated, “The sensitivity of both NUC-resistant and CpAM-resistant strains to inarigivir and the lack of cross-resistance is beneficial for combination studies since inarigivir will cover both pre- existing resistant variants and prevent treatment-emergent resistance to both NUCs and CpAM inhibitors,” said Dr. Locarnini.

Inarigivir Clinical Development

Spring Bank has launched two Phase 2 global trials (CATALYST 1 and CATALYST 2) examining the administration of inarigivir 400mg as monotherapy and co-administered with a NUC in naïve and virally-suppressed chronic HBV patients. The CATALYST trials include multiple patient cohorts with dosing periods to include 12 weeks, 24 weeks, and 48 weeks. In addition, Gilead Sciences, Inc. is conducting a Phase 2 trial examining (i) the co-administration of inarigivir 50mg and tenofovir alafenamide 25mg (marketed by Gilead as Vemlidy®) in naïve chronic HBV patients, (ii) the co-administration of inarigivir 200mg and Vemlidy® in naïve chronic HBV patients and (iii) the administration of inarigivir 100mg in virally-suppressed patients who currently are and continue to be treated with a NUC.
