Forward Looking Statements Statements in this presentation that are not descriptions of historical facts are forward ‐ looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. We have attempted to identify forward ‐ looking statements by terminology including “anticipates,” “believes,” “can,” “continue,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “should,” or “will” or the negative of these terms or other comparable terminology. Forward ‐ looking statements are based on management’s current expectations and are subject to risks and uncertainties that could negatively affect our business, operating results, financial condition and stock price. Factors that could cause actual results to differ materially from those currently anticipated are risks relating to: our growth strategy; results of research and development activities; uncertainties relating to preclinical and clinical testing; our dependence on third party suppliers; our ability to obtain, perform under and maintain financing and strategic agreements and relationships; our ability to attract, integrate, and retain key personnel; the early stage of products under development; our need for substantial funds; government regulation; patent and intellectual property matters; competition; as well as other risks described in our SEC filings. We expressly disclaim any obligation or undertaking to update or revise any statements contained herein to reflect any change in our expectations or any changes in events, conditions or circumstances after the date of this presentation. 2

Avenue and its Value Proposition What We Do and Why  We focus on pharmaceuticals for the  U.S. hospital market is concentrated acute/intensive care hospital setting and requires a small sales force  Our lead asset intravenous (IV)  Trend on “multimodal” treatment for tramadol is ready to enter Phase III pain favors new products that help development patients avoid strong narcotics  Tramadol is an opioid without the typical side effects of narcotics  We are a subsidiary of Fortress Biotech  Backing by Fortress’ BD effort = New that is run by an experienced pipeline product candidates management team and advisors 3

U.S. Post‐Op Pain Market  IV analgesics sells ~$1 billon (~300 million units)/yr  IV acetaminophen sells ~$250MM ‐ ~25% of total dollar market with approximately 3 to 4% of the volume  Room for Improvement Available Classes Pain Levels Common Limitations & Contraindications IV narcotics Moderate to severe Strong sedation Respiratory depression Constipation Risk of dependence IV NSAIDS Mild to moderately Post ‐ op bleeding risk severe GI side effects Renal impairment IV acetaminophen Mild to moderate Hepatic impairment 4

What is Tramadol  Not a typical opioid  Two distinct mechanisms of action: (1)weak opioid agonist, and (2)inhibitor of monoamine neurotransmitter reuptake  Labeled for “moderate to moderately severe pain”  Analgesic effect similar to other opioid therapies  Differentiated safety profile compared to other opioids  Oral tramadol widely prescribed in the U.S.  Schedule IV and one of the most prescribed pain medications  Prescriptions increased from 23.3 million in 2008 to 43.8 million in 2013  ~$1.2 billion annual sales despite being generic  IV tramadol widely used outside the U.S.  Accounts for ~10% of IV analgesic use in the post ‐ op setting in E.U. 5

IV Tramadol Summary Indication Moderate to moderately severe pain Regulatory pathway 505b(2) Stage of development Phase III to begin in 2017 Clinical efficacy* Parenteral tramadol has been tested in several randomized, double ‐ • blind, parallel ‐ group, comparative studies. It effectively relieved moderate to severe post ‐ op pain associated with • several types of surgeries (abdominal, orthopedic, and cardiac surgery) in these studies. Tolerability* In general, tramadol was well tolerated in clinical studies. The most • common adverse events were nausea, dizziness, drowsiness, tiredness, sweating, vomiting, and dry mouth. Unlike other opioids, it did not cause clinically relevant respiratory • depression. *Tramadol: A Review of its Use in Perioperative Pain. Scott LJ, Perry CM. Drugs . 2000 Jul;60(1):139 ‐ 76. 6

New Restrictions on Opioids • New guidelines from CDC to physicians attempts to limit opioid prescribing • Many states have passed laws restricting opioid prescriptions • The U.S. DEA has reduced the amount of almost every Schedule II opioid medication that may be produced in the U.S. in 2017 by 25 percent or more 7

IV Tramadol Opportunity  IV tramadol may be used in all types of inpatient and outpatient surgeries and as part of a multimodal analgesic plan for major surgery  It may be an improved option for patients  With poor cardiopulmonary function  Elderly patients at risk for respiratory depression  Obese patients with sleep apnea  Contraindicated for NSAIDS  Patients who cannot tolerate strong narcotics such as morphine due to side effects such as sedation, constipation, and history of drug dependence, etc. 8

Results from a Survey of 30 U.S. Anesthesiologists* Patients taking Switch to IV tramadol Add IV tramadol IV morphine 40% 41% IV NSAIDS 26% 37% IV acetaminophen 24% 35% *Survey conducted through LEERINK and available upon request 9

Advantages of IV Tramadol  Documented efficacy and safety  Physician familiarity with tramadol  Less addictive than widely prescribed narcotics in the hospital  Available “step ‐ down” therapy  Our IV tramadol dosing regimen provides similar Cmax and AUC to that of oral Ultram 100 mg Q6h at steady state. 10

Phase 3 Program* Study Goals Design Orthopedic model 1. To demonstrate safety and 405 patients, 3 ‐ arm (IV tramadol (Bunionectomy) efficacy of IV tramadol (50 50 mg, 25 mg, or placebo), 1:1:1 mg dose) versus placebo randomized, and double ‐ blind 2. To understand dose study response Soft tissue model 1. To demonstrate safety and 360 patients, 3 ‐ arm (IV tramadol (Abdominoplasty) efficacy of IV tramadol (50 50 mg, placebo, or morphine), mg dose) versus placebo 3:3:2 randomized, and double ‐ 2. To understand safety and blind study tolerability versus standard of care Safety study 1. To achieve total exposure 250 patients, open ‐ label, single of 500 patients on IV arm, all surgical types tramadol (50 mg dose) 2. To understand safety in “real ‐ world” situations *Key elements clarified and confirmed at EOP2 Meeting 11
