Napo Pharmaceuticals Surveys of Neurologists, Patients, and Caregivers Regarding Amyotrophic Lateral Sclerosis (ALS) Treatment Indicate Real World Burden of Diarrhea and Potential Treatment Interruption

Jaguar Health family company Napo Pharmaceuticals focuses on essential supportive care and management of neglected toxicities in multiple complicated disease states

SAN FRANCISCO, CA / ACCESSWIRE / August 16, 2023 / Napo Pharmaceuticals, Inc. (Napo), a Jaguar Health, Inc. (NASDAQ:JAGX) family company, today announced that the results of a Napo-sponsored survey of 15 US neurologists who treat patients with amyotrophic lateral sclerosis (ALS), and the results of a corresponding Napo-sponsored survey of 15 US individuals who are either ALS patients or caregivers of an ALS patient, indicate that the burden of diarrhea associated with a commonly used treatment ("the ALS drug") for this rare progressive neurodegenerative disease may be higher than previously understood. Napo focuses on essential supportive care and management of neglected toxicities in multiple complicated disease states.

Highlights of the survey of neurologists:

• 87% reported the severity of diarrhea associated with the ALS drug as moderate to severe.
• Over half reported stopping a patient's use of the ALS drug due to diarrhea.
• 13% reported that ALS patients in their care had been hospitalized or required other medical interventions due to diarrhea while taking the ALS drug.
• 79% reported the impact of diarrhea on the quality of life of patients on the ALS drug as moderate to severe.
• 40% reported that patients in their care had skipped doses of the ALS drug due to diarrhea.

Highlights of the survey of ALS patients & caregivers:

• 93% of participants rated the severity of the diarrhea as moderate or higher. 27% rated it severe.
• Similarly, 93% rated the impact on quality of life as moderate or greater. 40% rated the impact severe.
• Almost half reported stopping the ALS drug due to diarrhea.
• 40% reported requiring hospitalization or some other medical intervention due to diarrhea.
• 67% of participants said diarrhea was experienced throughout the time on the ALS drug, with 20% reporting that symptoms increased over time.
• Slightly less than half took any medications to manage their diarrhea.

"The results of both surveys indicate that chronic diarrhea may be a substantial compliance issue of patients receiving the ALS drug, and that the severity of the diarrhea - and its impact on patient quality of life, dignity, and the ability of patients to remain on the drug - may be higher than previously understood," said Lisa Conte, Jaguar's president and CEO. "The data from the Napo-sponsored survey of individuals who are either ALS patients or caregivers of an ALS patient underscores the importance of real-world patient reported outcomes (PRO) data and the importance of managing side effects for critical diseases such as ALS or cancer. PRO is the primary endpoint of Napo's Phase 3 OnTarget clinical trial of crofelemer for preventative treatment of diarrhea in adult cancer patients receiving targeted therapy with or without cytotoxic chemotherapy, for which top line results are expected to be available in late October of this year."

"Crofelemer is a non-opioid, plant-derived molecule which is not absorbed systemically. It is a gastrointestinal chloride channel modulator. In alignment with our company focus on rare diseases, which includes clinical programs in short bowel syndrome and microvillus inclusion disease, we believe it is important to evaluate the potential of crofelemer's novel mechanism of action to improve the quality of life of patients treated with the ALS drug and help prevent discontinuations and dose reductions of their disease modifying medications due to diarrhea," Conte continued.

ALS, also known as Lou Gehrig's Disease, is a rare neurological disease that affects motor neurons - those nerve cells in the brain and spinal cord that control voluntary muscle movement. Voluntary muscles are those we choose to move to produce movements like chewing, walking, and talking. The disease is progressive, meaning the symptoms get worse over time. ALS has no cure and there is no effective treatment to reverse its progression.

There are currently an estimated 30,000 ALS patients in US, and by 2040 ALS incidence is predicted to increase worldwide by 70%, according to The ALS Association.
