Third Quarter and Recent Key Business Highlights

Corporate Update

• Lantheus Holdings, Inc. ("Lantheus") to Acquire Progenics to Form an Innovative Commercial Life Sciences Company with a Diversified Diagnostics and Therapeutics Portfolio 
  In October 2019, we announced the signing of a definitive agreement in which Lantheus will acquire Progenics in an all-stock transaction, offering a significant upside opportunity to the combined shareholders from a diversified, high growth portfolio with the potential for strong, growing profits. The combination of Lantheus and Progenics forms a leader in precision diagnostics and radiopharmaceutical therapeutics. The combined company will have significant product and cost synergies that will diversify and sustain growing revenues and will drive incremental profitability and cash flow.  The combined company will be led by Lantheus Chief Executive Officer, Mary Anne Heino. Ms. Heino will be supported by Chief Financial Officer, Robert J. Marshall Jr., and Chief Operations Officer, John Bolla. Following the closing, Bradley Campbell, currently a member of Progenics' Board of Directors, will be added as a member of the Board of Directors of Lantheus Holdings.
  
  The transaction is expected to close in the first quarter of 2020, subject to approval by Lantheus and Progenics stockholders, regulatory approvals, and customary closing conditions. Additional details can be found here.

AZEDRA (iobenguane I 131) 555 MBq/mL injection for intravenous use, Ultra-orphan Radiotherapeutic

• AZEDRA Commercial Dosing Progresses in U.S. as New Technology Add-On Payment Became Effective October 1^st; Ex-U.S. Managed Access Program for Patients Has Been Initiated 
  AZEDRA is the first and only approved therapy in the U.S. for the treatment of adult and pediatric patients 12 years and older with iobenguane scan positive, unresectable, locally advanced or metastatic pheochromocytoma or paraganglioma who require systemic anticancer therapy. Third quarter sales of AZEDRA totaled $0.6 million (first therapeutic doses for three new patients and a second therapeutic dose for one patient who previously received a first dose).  Sales of therapeutic doses of AZEDRA doubled over the preceding second quarter, and we expect them to double again in the fourth quarter. As a result, our guidance for 2019 AZEDRA sales is approximately $2.0 million.  The AZEDRA Managed Access program for appropriate commercial patients in need of the therapy outside the U.S. was initiated which will provide additional access to AZEDRA.
  
  
• Life Cycle Management Trial to Support Expanded Label 
  We recently received comments and are currently in discussions with the U.S. Food and Drug Administration ("FDA") on our proposed life cycle management study to evaluate AZEDRA in patients with other neuroendocrine tumors (NETs). The proposed study is on clinical hold until we reach agreement with the FDA.  Assuming we can reach agreement with the FDA on an amended study, or possibly studies design, we intend to commence them next year.
  
  
• Expansion of Iodine Manufacturing Capacity Continues to Support Expected Increase in Demand for AZEDRA and 1095
  We are continuing our plans to expand manufacturing capacity for our iodine-based products and to provide redundancy. We are increasing the capacity of our Somerset, New Jersey manufacturing site by adding a second shift to increase to two batches a week from the current one batch a week schedule. We are also planning to build out the two additional existing manufacturing suites at the site to make them suitable for iodine manufacturing.  Currently at Somerset, we are capable of producing one batch per week (two to three therapeutic doses).  The second shift will double our capacity commencing in the second quarter of 2020.  We expect additional iodine manufacturing capability to become available from contract manufacturing partners starting in the second quarter of 2020.

PSMA-Targeted Prostate Cancer Pipeline

• Topline Data from Phase 3 Trial of PyL (18F-DCFPyL) Expected by Year End
  The Phase 3 CONDOR trial is a multi-center, open label trial that enrolled 208 male patients with biochemical recurrence of prostate cancer at 14 sites in the U.S. and Canada. Topline PyL data is expected by the end of the year. Based on prior discussions with the FDA, Progenics believes that positive data from the CONDOR study and the previously reported OSPREY study could serve as the basis for a New Drug Application for PyL. We currently estimate that the NDA for PyL will be submitted to the FDA in July 2020.
  
  
• Patient Dosing in Phase 2 Trial of 1095 Ongoing 
  The Company continues to dose patients in the ongoing 120-patient open-label Phase 2 trial of 1095 in combination with enzalutamide in chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC) who are PSMA avid by PyL imaging. 1095 is a small molecule radiotherapeutic designed to selectively bind to the extracellular domain of prostate specific membrane antigen (PSMA), a protein that is highly expressed on prostate cancer cells. Currently patients are being dosed at Canadian sites using 1095 produced by our contract manufacturing organization, CPDC.  CPDC has not been allowed to ship drug to the U.S. under an import alert.  Following lifting of the import ban by the FDA, Progenics will submit a request to utilize the CPDC drug at U.S. sites.  We expect that review of our request will be completed by the end of 2019, and initiation of dosing at U.S. clinical sites is expected to begin in the first quarter of 2020.

RELISTOR, Treatment for Opioid-Induced Constipation (partnered with Bausch Health Companies Inc.)

• Third Quarter 2019 World-Wide RELISTOR Net Sales of $32.7 Million
  The third quarter 2019 world-wide net sales of RELISTOR, as reported by its partner Bausch Health Companies, Inc., translated to $4.9 million in royalty revenue for Progenics for the quarter compared to $5.2 million for the third quarter of 2018. 2019 year to date U.S. sales of RELISTOR are $82.8 million compared to $76.2 million for the same period in 2018.

Third Quarter 2019 Financial Results

Third quarter revenue totaled $5.6 million, up from $5.3 million in the third quarter of 2018.

Third quarter research and development expenses increased by $3.3 million compared to the corresponding prior year period, primarily resulting from higher costs associated with the 1095 clinical trial, the transition of the Somerset manufacturing site, and initiatives to increase production capacity and provide redundancy for iodine-based products, AZEDRA and 1095. Third quarter selling, general and administrative expenses increased by $4.4 million compared to the corresponding prior year period, primarily due to increases in legal and advisory fees associated with the acquisition agreement with Lantheus and the contested election at our 2019 annual meeting of shareholders and the ongoing consent solicitation campaign. Progenics also recorded non-cash adjustments of $0.5 million in the third quarter of 2019, related to changes in the fair value estimate of the contingent consideration liability. For the three months ended September 30, 2019, Progenics recognized interest expense of $1.0 million related to the RELISTOR royalty-backed loan.

Net loss for the third quarter was $18.8 million, or $0.22 per diluted share, compared to net loss of $24.4 million, or $0.30 per diluted share, in the corresponding 2018 period.

Progenics ended the third quarter with cash and cash equivalents of $64.5 million, a decrease of $73.2 million compared to cash and cash equivalents as of December 31, 2018, reflecting primarily cash used for operating expenses and for the acquisition of the Somerset manufacturing site for AZEDRA, as well as for the capital expenditures to increase production capacity to satisfy increasing expected demand and provide redundancy for iodine-based products.

Indication
AZEDRA^® (iobenguane I 131) is indicated for the treatment of adult and pediatric patients 12 years and older with iobenguane scan positive, unresectable, locally advanced or metastatic pheochromocytoma or paraganglioma who require systemic anticancer therapy.

Important Safety Information
Warnings and Precautions:
Risk from radiation exposure: AZEDRA contributes to a patient's overall long-term radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. These risks of radiation associated with the use of AZEDRA are greater in pediatric patients than in adults. Minimize radiation exposure to patients, medical personnel, and household contacts during and after treatment with AZEDRA consistent with institutional good radiation safety practices and patient management procedures.
Myelosuppression: Severe and prolonged myelosuppression occurred during treatment with AZEDRA. Among the 88 patients who received a therapeutic dose of AZEDRA, 33% experienced Grade 4 thrombocytopenia, 16% experienced Grade 4 neutropenia, and 7% experienced Grade 4 anemia. Five percent of patients experienced febrile neutropenia. Monitor blood cell counts weekly for up to 12 weeks or until levels return to baseline or the normal range. Withhold and dose reduce AZEDRA as recommended in the prescribing information based on severity of the cytopenia.
Secondary myelodysplastic syndrome, leukemia, and other malignancies: Myelodysplastic syndrome (MDS) and acute leukemias were reported in 6.8% of the 88 patients who received a therapeutic dose of AZEDRA. The time to development of MDS or acute leukemia ranged from 12 months to 7 years. Two of the 88 patients developed a non-hematological malignancy.
Hypothyroidism: Hypothyroidism was reported in 3.4% of the 88 patients who received a therapeutic dose of AZEDRA. Initiate thyroid-blocking medications starting at least 1 day before and continuing for 10 days after each AZEDRA dose to reduce the risk of hypothyroidism or thyroid neoplasia. Evaluate for clinical evidence of hypothyroidism and measure thyroid-stimulating hormone (TSH) levels prior to initiating AZEDRA and annually thereafter.
Elevations in blood pressure: Eleven percent of the 88 patients who received a therapeutic dose of AZEDRA experienced a worsening of pre-existing hypertension defined as an increase in systolic blood pressure to ≥160 mmHg with an increase of 20 mmHg or an increase in diastolic blood pressure to ≥100 mmHg with an increase of 10 mmHg. All changes in blood pressure occurred within the first 24 hours post infusion. Monitor blood pressure frequently during the first 24 hours after each therapeutic dose of AZEDRA.
Renal toxicity: Of the 88 patients who received a therapeutic dose of AZEDRA, 7% developed renal failure or acute kidney injury and 22% demonstrated a clinically significant decrease in glomerular filtration rate (GFR) measured at 6 or 12 months. Monitor renal function during and after treatment with AZEDRA. Patients with baseline renal impairment may be at greater risk of toxicity; perform more frequent assessments of renal function in patients with mild or moderate impairment. AZEDRA has not been studied in patients with severe renal impairment.
Pneumonitis: Fatal pneumonitis occurred 9 weeks after a single dose in one patient in the expanded access program. Monitor patients for signs and symptoms of pneumonitis and treat appropriately.
Embryo-fetal toxicity: Based on its mechanism of action, AZEDRA can cause fetal harm. Verify pregnancy status in females of reproductive potential prior to initiating AZEDRA. Advise females and males of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment with AZEDRA and for 7 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 4 months after the final dose.
Risk of infertility: Radiation exposure associated with AZEDRA may cause infertility in males and females. Radiation absorbed by testes and ovaries from the recommended cumulative dose of AZEDRA is within the range where temporary or permanent infertility can be expected following external beam radiotherapy.

Adverse Reactions:
The most common severe (Grade 3–4) adverse reactions observed in AZEDRA clinical trials (≥10%) were lymphopenia (78%), neutropenia (59%), thrombocytopenia (50%), fatigue (26%), anemia (24%), increased international normalized ratio (18%), nausea (16%), dizziness (13%), hypertension (11%), and vomiting (10%). Twelve percent of patients discontinued treatment due to adverse reactions (thrombocytopenia, anemia, lymphopenia, nausea and vomiting, multiple hematologic adverse reactions).
Drug Interactions:
Based on the mechanism of action of iobenguane, drugs that reduce catecholamine uptake or that deplete catecholamine stores may interfere with iobenguane uptake into cells and therefore interfere with dosimetry calculations or the efficacy of AZEDRA. These drugs were not permitted in clinical trials that assessed the safety and efficacy of AZEDRA. Discontinue the drugs listed in the prescribing information for at least 5 half-lives before administration of either the dosimetry dose or a therapeutic dose of AZEDRA. Do not administer these drugs until at least 7 days after each AZEDRA dose.
For important risk and use information about AZEDRA, please see Full Prescribing Information.

About RELISTOR^®

Progenics has exclusively licensed development and commercialization rights for its first commercial product, RELISTOR, to Bausch Health Companies, Inc. RELISTOR Tablets (450 mg once daily) are approved in the United States for the treatment of opioid-induced constipation (OIC) in patients with chronic non-cancer pain. RELISTOR Subcutaneous Injection (12 mg and 8 mg) is a treatment for OIC approved in the United States and worldwide for patients with advanced illness and chronic non-cancer pain.

IMPORTANT SAFETY INFORMATION - RELISTOR (methylnaltrexone bromide) tablets, for oral use and RELISTOR (methylnaltrexone bromide) injection, for subcutaneous use

RELISTOR tablets and injection are contraindicated in patients with known or suspected gastrointestinal obstruction and patients at increased risk of recurrent obstruction, due to the potential for gastrointestinal perforation.

Cases of gastrointestinal perforation have been reported in adult patients with opioid-induced constipation and advanced illness with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the gastrointestinal tract (e.g., peptic ulcer disease, Ogilvie's syndrome, diverticular disease, infiltrative gastrointestinal tract malignancies or peritoneal metastases). Take into account the overall risk-benefit profile when using RELISTOR in patients with these conditions or other conditions which might result in impaired integrity of the gastrointestinal tract wall (e.g., Crohn's disease). Monitor for the development of severe, persistent, or worsening abdominal pain; discontinue RELISTOR in patients who develop this symptom.

If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their healthcare provider.

Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, and yawning have occurred in patients treated with RELISTOR. Patients having disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal and/or reduced analgesia and should be monitored for adequacy of analgesia and symptoms of opioid withdrawal.

Avoid concomitant use of RELISTOR with other opioid antagonists because of the potential for additive effects of opioid receptor antagonism and increased risk of opioid withdrawal.

The use of RELISTOR during pregnancy may precipitate opioid withdrawal in a fetus due to the immature fetal blood brain barrier and should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Because of the potential for serious adverse reactions, including opioid withdrawal, in breastfed infants, advise women that breastfeeding is not recommended during treatment with RELISTOR. In nursing mothers, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. 

A dosage reduction of RELISTOR tablets and RELISTOR injection is recommended in patients with moderate and severe renal impairment (creatinine clearance less than 60 mL/minute as estimated by Cockcroft-Gault). No dosage adjustment of RELISTOR tablets or RELISTOR injection is needed in patients with mild renal impairment.

A dosage reduction of RELISTOR tablets is recommended in patients with moderate (Child-Pugh Class B) or severe (Child-Pugh Class C) hepatic impairment. No dosage adjustment of RELISTOR tablets is needed in patients with mild hepatic impairment (Child-Pugh Class A). No dosage adjustment of RELISTOR injection is needed for patients with mild or moderate hepatic impairment. In patients with severe hepatic impairment, monitor for methylnaltrexone-related adverse reactions. 
In the clinical studies, the most common adverse reactions were:

OIC in adult patients with chronic non-cancer pain

• RELISTOR tablets (≥ 2% of RELISTOR patients and at a greater incidence than placebo): abdominal pain (14%), diarrhea (5%), headache (4%), abdominal distention (4%), vomiting (3%), hyperhidrosis (3%), anxiety (2%), muscle spasms (2%), rhinorrhea (2%), and chills (2%).
• RELISTOR injection (≥ 1% of RELISTOR patients and at a greater incidence than placebo): abdominal pain (21%), nausea (9%), diarrhea (6%), hyperhidrosis (6%), hot flush (3%), tremor (1%), and chills (1%).

OIC in adult patients with advanced illness

• RELISTOR injection (≥ 5% of RELISTOR patients and at a greater incidence than placebo): abdominal pain (29%) flatulence (13%), nausea (12%), dizziness (7%), and diarrhea (6%).
