Petros Pharmaceuticals Announces Capital Raise of $15 Million

Provides Update on Progress Toward Over the Counter (non-prescription) Development of STENDRA

NEW YORK, NY / ACCESSWIRE / July 13, 2023 / Petros Pharmaceuticals, Inc. (Nasdaq:PTPI) ("Petros" or "the Company"), a pioneer in expanding consumer access to medication through the over the counter (OTC) pathway, today announces a $15 million private placement financing that will support its continued progress towards bringing its erectile dysfunction (ED) drug, STENDRA, to non-prescription OTC status.

Petros raised $15 million from this private placement, which was led by its largest existing shareholders. The funds raised combined with the cash on its balance sheet ($8.3 million as of March 31, 2023), is expected to provide the Company with a strong cash position that will fund its initiatives through the end of 2024, enabling significant progress on its pathway to OTC approval as well as partnership opportunities. The closing of the private placement is subject to customary closing conditions and is expected to occur on or around July 17, 2023.

Since announcing the completion of a series of initial formative studies, Petros has continued to progress in its development program. Recently, the Company has conducted three engagements with the U.S. Food and Drug Administration (FDA) reviewing data and receiving guidance, launched a second pivotal Label Comprehension Study incorporating FDA feedback, and has begun to integrate supportive technology in response to recent FDA industry-wide guidance and proposed rules. This financing will enable the organization to continue its progress.

"We have made substantial progress in our efforts to achieve OTC status for STENDRA, which could be the first prescription ED drug to achieve non-prescription designation," commented Fady Boctor, Petros Pharma's President and Chief Commercial Officer. "The continued investment and support by our largest shareholders highlight their commitment to our strategy, sharing our excitement and passion. With this financing we believe we will be well capitalized through 2024 and to the completion of significant milestones along the OTC pathway, including significant interactions with FDA, multiple data readouts, as well as key technology and developmental partnerships, which we believe are essential to the successful execution of an OTC strategy.

"According to Market.us, it is estimated that the total ED market will reach $6.1 billion by 2032 with an average CAGR of 6.8%. The estimated revenue share for North America alone is 51% of that estimate, and we believe these to be understated based on an observed hesitance on the part of most men to seek treatment, even with the option to access these via online prescriptions.1

"Given this substantial Rx ED market, we believe that the prospects of expanded nonprescription access of prescription-grade ED therapy has the potential to significantly multiply this market's growth. With several recently publicized positive OTC switch events, and the potential for applying the principals of AI to ensure that those who are appropriate to receive it do, we have boldly identified this mission of developing STENDRA as the potentially first prescription-grade pharmaceutical available without a prescription, as our primary objective as a company," concluded Mr. Boctor.

The company believes that its technology platform designed for this program may also apply to future asset candidates, enabling an expansion to the company's future portfolio and overall opportunity.

About the OTC Pathway

The process of switching a prescription medication to over-the-counter (OTC) involves the design of a clear to laymen, shelf-friendly medication label, demonstrated comprehension of key safety parameters, and proven, appropriate consumer self-selection. The FDA ordinarily requires a consumer tested OTC Drug Facts label (DFL), Label Comprehension Studies (LCS), Self Selection Studies (SSS), and at least one Actual Use Trial (AUT) demonstrating safe and appropriate non-practitioner-guided, yet consumer-led use. Recently, a communication by FDA introduced Additional Conditions for Non-prescription Use (ACNU) criteria that may expand OTC access to several prescription medications and enable innovative tools to help support the switch process.

About STENDRA® (avanafil)

Stendra® (avanafil), originally launched by Auxilium Pharmaceuticals prior to that company's sale to Endo Pharmaceuticals, is an oral phosphodiesterase 5 (PDE5) inhibitor for the treatment of erectile dysfunction. STENDRA is not for use in women or children. It is not known if STENDRA is safe and effective in women or children under 18 years of age. (A 100-mg and 200-mg tablet can be taken as early as ~15 minutes before sexual activity. STENDRA only works with sexual stimulation and should not be taken more than once a day. STENDRA can be taken with or without food; do not drink too much alcohol when taking STENDRA (for example, more than 3 glasses of wine or 3 shots of whiskey) as it can increase chances of side effects. Of people enrolled in clinical trials, 1.4%, 2.0%, and 2.0%, respectively, stopped taking STENDRA (50 mg, 100 mg, or 200 mg) due to side effects compared to 1.7% on placebo. Stendra® was designed and developed expressly for erectile dysfunction. The Company recently undertook a relaunch of Stendra®, generating gross revenues of approximately $30 million in 2019. Petros intends to accelerate the relaunch of Stendra® with a well-funded commercial organization and refocused strategy.

STENDRA Important Risk Information

STENDRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. A sudden drop in blood pressure can cause you to feel dizzy, faint, or have a heart attack or stroke.

Do not take STENDRA if you:

• take medicines called nitrates, which are used to treat chest pain (angina)
• use street drugs called "poppers," such as amyl nitrate and butyl nitrate
• take medicines called guanylate cyclase stimulators, which include Adempas® (riociguat), a medicine that treats pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension
• are allergic to avanafil or any of the ingredients in STENDRA

Stop sexual activity and get medical help right away if you have symptoms such as chest pain, dizziness, or nausea during sex. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease. Discuss your health with your healthcare provider to ensure you are healthy enough for sex.

STENDRA can cause serious side effects.

Uncommonly reported side effects include:

• An erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help right away.
• Sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). It is uncertain whether PDE5 inhibitors directly cause vision loss. Stop taking STENDRA and call your healthcare provider right away if you have sudden vision loss in one or both eyes.
• Sudden hearing decrease or hearing loss. Some people may also have ringing in their ears (tinnitus) or dizziness.

Before you take STENDRA, tell your healthcare provider if you:

Tell your healthcare provider about all of the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. STENDRA may affect the way other medicines work, and other medicines may affect the way STENDRA works, which may cause side effects. Especially tell your healthcare provider if you take any of the following:

• medicines called nitrates
• medicines called guanylate cyclase stimulators, such as riociguat
• medicines called HIV protease inhibitors, such as ritonavir (Norvir®), indinavir (Crixivan®), saquinavir (Fortavase® or Invirase®), or atazanavir (Reyataz®)
• some types of oral antifungal medicines, such as ketoconazole (Nizoral®) and itraconazole (Sporanox®)
• some types of antibiotics, such as clarithromycin (Biaxin®), telithromycin (Ketek®), or erythromycin
• medicines called alpha-blockers. These include terazosin (Hytrin®), tamsulosin HCl (Flomax®), doxazosin (Cardura®), prazosin HCl (Minipress®), alfuzosin HCl (UroXatral®), dutasteride and tamsulosin HCl (Jalyn®), or silodosin (Rapaflo®). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients, the use of STENDRA with alpha-blockers can lead to a drop in blood pressure or fainting
• other medicines that treat high blood pressure
• other medicines or treatments for ED

Do not drink too much alcohol (for example, more than 3 glasses of wine or 3 shots of whiskey) when taking STENDRA, as this can lead to increased chances of headache, dizziness, increased heart rate, or lowered blood pressure.

STENDRA does not protect against sexually transmitted diseases, including HIV.

The most common side effects of STENDRA are headache, flushing, stuffy or runny nose, sore throat, and back pain.

Tell your healthcare provider if you have any side effect that bothers you or does not go away. These are not all of the possible side effects of STENDRA. For more information, ask your healthcare provider or pharmacist. Call your healthcare provider for medical advice about side effects.
