OTC NCT01044212 ↗ Bowel Function After Minimally Invasive Urogynecologic Surgery Completed University of Rochester N/A 2009-11-01 The purpose of this study is to assess the effect of a standardized postoperative bowel regimen of over-the-counter medications in subjects undergoing minimally invasive urogynecologic surgery.
New Formulation NCT01325896 ↗ Maintenance Treatment of Multiple Myeloma (MM) After Autologous Peripheral Blood Transplant (PBSCT) Using Polyethylene Glycol alpha2B Interpheron (PEG-INTRON) Unknown status Haematology Service, Phase 2 2002-09-01 - Multiple myeloma accounts for approximately 1% of all cancers and 10% of hematologic malignancies. Between 50 and 70% of symptomatic patients presented response to induction chemotherapy. The rate of complete responses (CR) achieved with standard induction of these treatments is less than 5% of cases and the median event-free survival between 2 and 3 years although most of the patients died from the disease. - High dose chemotherapy with autologous stem cell transplant has improved the response rate and survival of patient with MM. However eventually all patients relapse with a median EFS between 40-50 months post-transplant. - To improve these results and sustain remission, various maintenance treatment have been proposed as is the case of Interpheron alpha2b s.c. (Intron A) that has shown benefits in a meta-analysis. - Intron A s.c. need administration of 3 days per week and is not well tolerated - Recently a new formulation of Interpheron alpha2b is available. Conjugated with polietilenglicol (Pegintron) that need only one dose weekly and has not been tested in MM. - The purpose of this study is to evaluate the role of Pegintron as maintenance after autologous transplant in MM
New Formulation NCT01325896 ↗ Maintenance Treatment of Multiple Myeloma (MM) After Autologous Peripheral Blood Transplant (PBSCT) Using Polyethylene Glycol alpha2B Interpheron (PEG-INTRON) Unknown status Fundación de Investigación Biomédica - Hospital Universitario de La Princesa Phase 2 2002-09-01 - Multiple myeloma accounts for approximately 1% of all cancers and 10% of hematologic malignancies.

New Dosage NCT01533090 ↗ Evaluation of Reduced-volume PEG Bowel Preparation Administered the Same Day of Colonoscopy Completed Catholic University of the Sacred Heart N/A 2010-04-01 The conventional total dose of 4 L of polyethylene glycol (PEG) given the day before the procedure is safe and effective. It has been the standard cleansing regimen for the last 25 years. To overcome the difficulty in completing the bowel preparation due to large volume and/or taste, reduced-volume (mixed) bowel preparation of bisacodyl and 2 L of PEG have been shown to provide adequate colon cleansing and better tolerability. LoVol-esse is a reduced-volume PEG-based bowel preparation to be used in combination with bisacodyl and designed to improve patient tolerability and attitude toward bowel cleansing prior to colonoscopy thanks to the reduced volume and improved taste. The present study is intended to compare the new dosing regimen of the bowel lavage solution given the same day compared with standard PEG formulation (SELG 1000) given the day before colonoscopy.

NCT00001410 ↗ PEG-Glucocerebrosidase for the Treatment of Gaucher Disease Completed National Institute of Mental Health (NIMH) Phase 1 1993-10-01 Gaucher disease is a lysosomal storage disease resulting from glucocerebroside accumulation in macrophages due to a genetic deficiency of the enzyme glucocerebrosidase. It may occur in patients of all ages. The condition is marked by enlargement of the liver and spleen (hepatosplenomegaly), low blood and platelet counts, and bone abnormalities. The condition is passed from generation to generation on via autosomal recessive inheritance. There are actually three types of Gaucher disease. Type I is the most common form. It is a chronic non-neuronopathic form, meaning the disease does not affect the nervous system. The symptoms of type I can appear at any age. Type 2 Gaucher disease presents prenatally or in infancy and usually results in death for the patient. Type 2 is an acute neuronopathic form and can affect the brain stem. It is the most severe form of the disease. Type 3 Gaucher disease is also neuronopathic, however it is subacute in nature. This means the course of the illness lies somewhere between long-term (chronic) and short-term (acute). Currently there is not a cure for Gaucher disease. Treatment for the disease has traditionally been supportive. In some severely affected patients, bone-marrow transplants have corrected the enzyme deficiency, but it is considered a high-risk procedure and recovery can be very slow. Enzyme replacement therapy is another therapy option and has been approved by the Food and Drug Administration (FDA) for use in type 1 patients. PEG-glucocerbrosidase is a drug designed to clear out the accumulation of lipid (glucocerebroside) from the blood stream. The drug is actually an enzyme attached to large molecules called polyethylene glycol (PEG). The large molecules of PEG allow the enzyme to remain in the blood stream for long periods of time. By modifying glucocerebrosidase with PEG, it is believed that smaller doses will be required, meaning a reduction in cost for the patient and more convenient administration of the drug. The purpose of this study is to evaluate the effects and safety of enzyme replacement therapy using PEG- glucocerebrosidase for the treatment of Gaucher disease.
NCT00004695 ↗ Randomized Study of Polyethylene-Glycol-Conjugated Interleukin 2 in Patients With Common Variable Immunodeficiency Completed Icahn School of Medicine at Mount Sinai N/A 1997-09-01 OBJECTIVES: I. Determine whether polyethylene-glycol-conjugated interleukin 2 (PEG-IL-2) can reduce the number of infections in patients with common variable immunodeficiency. II. Determine whether this therapy can improve lung functions in these patients with pulmonary impairment.
NCT00018031 ↗ Peginterferon Alpha-2b And Ribavirin to Treat Hepatitis C in HIV-Infected Patients Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 2001-06-01 This study will evaluate the safety and effectiveness of combination therapy with peginterferon alfa-2b and ribavirin for treating hepatitis C virus (HCV) infection in HIV-infected patients. In studies of patients with hepatitis C alone, interferon alfa-2b plus ribavirin treatment eradicated the HCV in almost half the patients. Peginterferon alfa-2b is a compound that results from attaching a polyethylene glycol molecule to interferon alfa-2b. This compound stays in the blood longer than unmodified interferon alfa-2b, causing a higher blood concentration and thus maintaining activity against the hepatitis C virus. HIV-infected patients 21 years of age and older with chronic hepatitis C infection and a viral load greater than 2000 copies/mL may be eligible for this 2 1/2-year study. Candidates will be screened with blood and urine tests and possibly a liver biopsy, if a recent one is not available. The liver biopsy is done to determine the severity of liver disease. For this test, patients are admitted to the NIH Clinical Center for 1 to 2 days. A sedative is injected into an arm vein, the skin in the area over the biopsy site is numbed with a local anesthetic, and a needle is inserted rapidly into and out of the liver to obtain a small tissue sample. The patient remains in the hospital overnight for monitoring. A chest X-ray, electrocardiogram (EKG) and liver ultrasound are also done. Within 4 weeks of the screening tests, candidates who appear eligible for the study will have a physical examination, medical history and repeat blood tests. Women who can become pregnant will have serial pregnancy tests throughout the study. Patients who meet the study criteria and decide to participate will begin treatment with weekly injections under the skin of peginterferon alfa-2b and take ribavirin pills twice a day by mouth. In addition, patients will continue to take all other medications prescribed by their doctor. Clinic visits will be scheduled as follows: - Days 1, 3, 5, 7, 10 and 21 - Blood will be drawn for safety tests and to measure blood levels of HIV and HCV. - Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 52, 56 and 64 - Blood and urine tests will be done to determine the side effects of treatment and its effect on the HCV infection. - Week 48 or end of treatment - Treatment will stop after 48 weeks. At this time, or earlier for those who do not complete the 48 weeks, patients will return to the clinic for a routine test.
NCT00029900 ↗ ADI-PEG in Patients With Metastatic Melanoma Completed FDA Office of Orphan Products Development Phase 1 2001-09-01 This is a study to determine the safety and toxicity of increasing doses of arginine deiminase combined to polyethylene glycol (ADI-PEG) in patients with nonresectable metastatic melanoma.
NCT00056992 ↗ Testing of ADI-PEG in Hepatocellular Carcinoma Completed FDA Office of Orphan Products Development Phase 2 2002-09-01 Amino acid deprivation therapy is an effective means for the treatment of some forms of cancer. Recently it has been found that human hepatocellular carcinomas (HCC) cell lines appear to require arginine for growth. Arginine is not an essential amino acid for human adults or infants as it can be synthesized from citrulline (for review see Rogers 1994). Therefore, selective elimination of arginine from the circulation may be a means of treating patients with metastatic melanoma or non resectable HCC. The enzyme arginine deiminase (ADI) metabolizes arginine into citrulline (Cunin 1986). However, ADI is only found in microbes and not in humans. ADI is therefore, highly immunogenic and has a short serum half-life following injection. These potential drawbacks (microbial source and thus viewed as foreign by the human immune system, and a short serum half-life) can be overcome by covalent attachment of polyethylene glycol (PEG) to argininedeiminase and termed this drug ADI-PEG 20. ADI-PEG 20 appears to be an effective anti-cancer treatment for human HCC. Pharmacokinetic and pharmacodynamic data indicates a once a week injection of 160 IU/m2 of ADI-PEG 20 eliminates all detectable arginine from the circulation for at least 7 days. This treatment appears to be well tolerated. The purpose of this study is to determine the efficacy of this treatment in patients with HCC. Efficacy is a primary end point of this study. No patients will recieve placebo.
NCT00085917 ↗ Peginterferon Alpha-2a and Ribavirin to Treat Hepatitis C in HIV-infected Patients Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 2004-06-01 This study will evaluate the safety and effectiveness of combination therapy with peginterferon alpha-2a and ribavirin for treating hepatitis C virus (HCV) infection in HIV-infected patients. Peginterferon alpha with ribavirin is the therapy of choice for people with HCV alone. Peginterferon alpha-2a is a compound that results from attaching a polyethylene glycol molecule to interferon alpha-2a. This compound stays in the blood longer than unmodified interferon alpha-2a, causing a higher blood concentration and thus maintaining greater activity against the hepatitis C virus. HIV-infected patients 18 years of age and older with chronic hepatitis C infection and a viral load greater than 2000 copies/mL may be eligible for this 2-1/2 year study. Candidates are screened with a medical history and physical examination, blood and urine tests, eye examination, chest x-ray, electrocardiogram (EKG), liver ultrasound, and pregnancy test in women who are able to become pregnant. If a recent liver biopsy is not available, this test is done to determine the type and severity of liver disease. The patient is given a sedative before the procedure. Then, the skin in the area over the biopsy site is numbed with a local anesthetic and a needle is inserted rapidly into and out of the liver to obtain a small tissue sample. The patient remains in the hospital overnight for monitoring. Participants begin treatment with injections under the skin of peginterferon alpha-2a and ribavirin pills by mouth on study day 0. Peginterferon is given either once or twice a week for 4 weeks and then once a week for 44 weeks. Ribavirin is given daily. In addition, patients continue to take all other medications prescribed by their doctor. Clinic visits are scheduled for the following procedures: - Days 1, 3, 4, 7, 10 and weeks 2, 3, and 4 - Blood tests for safety measures and to measure blood levels of HIV and HCV. - Weeks 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 - Blood and urine tests to determine the side effects of treatment and its effect on the HCV infection. In addition, eye examinations are done every 3 months, and pregnancy and thyroid function tests are done several times during the treatment period. - Week 48 or end of treatment - Treatment stops after 48 weeks. At this time, or earlier for those who do not complete the 48 weeks, patients return to the clinic for a chest x-ray, EKG, blood tests, and abdominal ultrasound. Patients are hospitalized for a repeat liver biopsy. - Weeks 52, 56, 64 and 72 - Blood and urine tests to determine the side effects of treatment and its effect on the HCV infection, and a urine pregnancy test in women.
NCT00090753 ↗ A Study of Intravenous or Subcutaneous Methoxy Polyethylene Glycol-Epoetin Beta (RO0503821, Mircera) in Chronic Kidney Disease Patients With Renal Anemia Completed Hoffmann-La Roche Phase 3 2004-10-01 This study assessed the long-term efficacy, safety, and tolerability of intravenous (iv) or subcutaneous (sc) methoxy polyethylene glycol-epoetin beta in chronic kidney disease patients with renal anemia. Eligible patients were those who were receiving stable maintenance therapy with methoxy polyethylene glycol-epoetin beta or erythropoiesis stimulating agents (ESAs) in Phase II or III clinical studies. They continued to receive methoxy polyethylene glycol-epoetin beta or comparator ESAs at the same weekly dose and by the same route of administration (sc or iv) as in the qualifying studies.

Polyethylene Glycol 3350 clinical trials update, market analysis, and revenue projection (US and key ex-US markets)

Executive summary: Polyethylene glycol 3350 (PEG 3350; macrogol 3350) is a mature, off-patent-os-by-typical-product class with ongoing clinical activity focused on pediatric constipation regimens, comparative efficacy vs other laxatives, and safety/tolerability in longer use. Market growth is driven by pediatric and adult functional constipation incidence, low switching costs within OTC and Rx categories, and package-size and dosing-form innovation (powder vs chewables vs blends). Revenue modeling is constrained by product heterogeneity (multiple labeled indications, multiple branded and store-brand equivalents, and differing regulatory status across geographies). Net projections below use a class-based approach anchored to constipation/laxative category demand, PEG share assumptions, and typical pricing compression from generic and private-label competition.


What clinical trials are evaluating polyethylene glycol 3350 for constipation in 2024–2026?

Clinical-trials signal: Trial activity for PEG 3350 clusters around (1) functional constipation in children, (2) chronic constipation maintenance dosing, (3) stooling response endpoints (time to first bowel movement, stool consistency, responder rates), (4) comparative outcomes vs lactulose, magnesium hydroxide, senna, bisacodyl, lubiprostone, linaclotide, plecanatide, and low-dose stimulant add-ons, and (5) safety endpoints including electrolyte status, abdominal pain, fecal incontinence, and adherence.

How are PEG 3350 trials measuring efficacy?

Common primary endpoints in constipation trials using PEG 3350 include:

  • Time to first bowel movement
  • Weekly spontaneous bowel movements (CSBM)
  • Stool consistency (typically Bristol Stool Form Scale categories)
  • Proportion of “responders” meeting predefined stool frequency and consistency thresholds
  • Maintenance of response over treatment windows ranging from 2 to 12+ weeks (pediatric maintenance trials often extend longer)

What safety endpoints show up most in PEG 3350 studies?

  • Electrolytes (especially in higher-dose or longer-duration use)
  • Abdominal pain and bloating
  • Nausea/vomiting
  • Urinary retention signals (where monitored)
  • Adherence and discontinuation rates

Which patient segments are most common?

  • Pediatric functional constipation and encopresis
  • Adult functional constipation
  • Opioid-induced constipation is frequently studied with PEG-based regimens, but many trials use combination products or different PEG molecular weight ranges, which complicates direct cross-study comparability.

Are there any new polyethylene glycol 3350 formulations or delivery systems in clinical development?

Featured snippet answer: PEG 3350 product innovation is mostly formulation and regimen-level, not new molecular entities. The clinical development runway generally centers on dosing convenience (taste, mixing characteristics), regimen simplification for pediatric adherence, and combination approaches rather than new active ingredients.

Key formulation themes

  • Powder stick-packs and unit-dose sachets for pediatric and caregiver dosing accuracy
  • Blended formulations that aim to reduce odor and improve palatability without changing the PEG 3350 active
  • Alternative dosing devices (for example, pre-measured mixed sachets) to reduce administration errors
  • Trials that compare different PEG 3350 dose ranges and titration schedules rather than route changes (PEG 3350 is usually oral)

What is the Orange Book status of polyethylene glycol 3350 products?

Featured snippet answer: PEG 3350 is typically an old active ingredient with limited or no meaningful small-molecule exclusivity in the US for the base drug substance itself. Market authorization is dominated by multiple ANDA approvals and private-label versions depending on dosage form and label.

Why Orange Book listings matter less for PEG 3350

Even when individual products have formulation-specific patents, the core class is generally constrained by:

  • Multiple equivalent generics
  • Off-patent active ingredient status
  • Rapid competitive substitution across branded and store-brand powder formats

Implication for clinical trial ROI

Clinical programs in PEG 3350 are usually “differentiation by label or convenience,” not exclusivity capture. That pushes sponsors toward evidence that supports pediatric dosing schedules, tolerability, or comparative positioning to justify premium pricing (rare) or payer coverage distinctions (more common in Rx channels).


How strong is the patent estate for polyethylene glycol 3350, and what does that mean for new entrants?

Featured snippet answer: Patent strength is generally low at the active-ingredient level for PEG 3350, with potential pockets of protection around specific formulations, combinations, and manufacturing/process details depending on the product.

Typical patent estate architecture for PEG laxatives

  • Composition of matter patents (often expired or near-expired)
  • Formulation patents (powder blends, excipient systems, particle size constraints)
  • Method-of-use patents (pediatric constipation dosing regimens, maintenance titration protocols)
  • Process patents (less common as a barrier for entrants due to commoditized raw materials)

What that means for market access

  • High ease of generic entry for standard PEG 3350 powder formats
  • Higher barriers only when a sponsor claims specific formulation/packaging innovations plus label-specific clinical evidence
  • Frequent reliance on brand differentiation rather than patent differentiation

What is the market for polyethylene glycol 3350 in the US, and how fast is it growing?

Executive market framing: PEG 3350 sits inside US laxatives and constipation remedies demand, split across OTC and Rx channels and across adult functional constipation and pediatric constipation. Market expansion is supported by:

  • Aging population (adult constipation prevalence)
  • Persistent pediatric functional constipation incidence
  • Increasing preference for osmotic agents over stimulant laxatives for long-term use

However: PEG 3350’s market growth tends to lag premium chronic constipation prescription brands because it faces intense OTC and generic pricing pressure.

Market growth drivers

  • Unit growth from pediatric dosing episodes
  • Repeat purchases (maintenance, caregiver re-stocking)
  • Continued preference for osmotic agents in pediatric constipation management guidelines

Market growth headwinds

  • Price compression from generics and store brands
  • Substitution by alternative OTC osmotics and combinations
  • Channel shifts from Rx to OTC (and vice versa in certain payer environments)

What market share does polyethylene glycol 3350 have vs lactulose, magnesium hydroxide, senna, and stimulant combinations?

Featured snippet answer: PEG 3350 is typically one of the leading osmotic options, with competitive pressure from lactulose and magnesium salts (and from stimulant classes for rescue/short-term use). Exact share varies by country, channel (OTC vs Rx), and pediatric vs adult mix.

Competitive dynamics

  • Lactulose: often strong in pediatrics and favored by some clinicians; taste and GI side effects affect switching.
  • Magnesium hydroxide: competes on OTC access and cost, with renal-safety considerations limiting use.
  • Senna and bisacodyl: compete on shorter onset and “rescue” use; adverse cramping risk affects preference.
  • Prescription secretagogues and agonists (linaclotide, plecanatide, lubiprostone): compete more in chronic constipation refractory populations, where PEG remains a baseline first-line in many settings.

How do PEG 3350 clinical outcomes compare with other constipation therapies?

Featured snippet answer: PEG 3350 generally shows favorable stool frequency and tolerability profiles compared with lactulose and stimulant laxatives, with consistent safety signals for electrolytes at labeled dosing.

Where PEG 3350 tends to underperform

  • Rapid onset rescue requirements sometimes favor stimulant combinations
  • Severe refractory chronic constipation populations with comorbidities may shift to prescription agents with stronger effect sizes in subgroups

Where PEG 3350 tends to win

  • Pediatric functional constipation where long-term tolerability matters
  • Maintenance dosing regimes where electrolyte concerns and chronic stimulant exposure are disfavored

When does polyethylene glycol 3350 lose exclusivity and what does that mean for generics?

Featured snippet answer: There is typically no single “exclusivity date” for PEG 3350 as a class. Exclusivity is fragmented by product-level patents and by brand-level formulation/labeling. For market planning, the practical loss of exclusivity is already realized in most standard PEG 3350 powder dosage formats, with ongoing opportunities mainly tied to incremental product claims.

Commercial impact

  • Generics already saturate standard PEG powder channels in many markets.
  • Entry barriers are low; differentiation shifts to packaging convenience, dosing accuracy, and label support.

How many Paragraph IV challenges exist for polyethylene glycol 3350 products?

Featured snippet answer: Paragraph IV challenges are not a defining feature for PEG 3350 class products because the active ingredient is largely off-patent and multiple authorized generics already populate the market. Litigation-driven discovery is more common for niche formulation patents rather than the base drug.


What generic entry risks exist for polyethylene glycol 3350?

Featured snippet answer: Entry risk is low for standard PEG 3350 powders due to commodity economics and low patent barriers, but risk can exist at the margin for:

  • Product-specific formulation patents
  • Combination products (PEG plus additional actives)
  • Pediatric label claims supported by particular clinical datasets

Where risk clusters

  • Higher-priced “differentiated” SKUs
  • Prescription-branded formulations
  • Any product where a brand argues a specific manufacturing or formulation advantage

How is polyethylene glycol 3350 regulated across the US and key EU/UK markets?

Featured snippet answer: PEG 3350 is generally regulated as an established active ingredient used in laxative products; regulatory status differs by formulation, dosage form, and whether the product is OTC or Rx.

Key regulatory touchpoints

  • Labeling for pediatric dosing and contraindications (renal disease cautions are common for osmotics)
  • Product quality requirements (particle size consistency, impurity profiles)
  • Stability and mixing instructions for powder products

Market analysis: revenue projection for PEG 3350 based on class demand and pricing pressure

Method outline (class-based projection)

Because PEG 3350 is broadly marketed through many equivalents, projections are best built on:

  1. Expected constipation-treatment unit demand growth
  2. PEG osmotic share of that demand
  3. Average net price (ANP) trajectory under generic/private-label pressure
  4. Share shifts between OTC and Rx, and between PEG and competing laxatives

Base-case projection (global-ish, class-based; US-heavy assumptions)

Below is a decision-grade projection framework, not a SKU-level forecast.

Assumptions

  • PEG 3350 use is primarily in functional constipation across adult and pediatric.
  • PEG 3350 pricing continues to compress modestly as private label and generics scale.
  • Unit demand grows faster than revenue due to lower real pricing.

Projection ranges

  • US revenue CAGR (base-case): low single digits (1%–4%) depending on OTC private-label penetration and pediatric usage stability.
  • Ex-US revenue CAGR (base-case): low single digits (2%–5%) with stronger growth where PEG uptake is still displacing other osmotics.

Scenario sensitivities

  • Upside: stronger guideline adherence, pediatric dosing pipeline expansion, and improved compliance from convenient packaging.
  • Downside: stronger substitution to other osmotics or prescription secretagogues in chronic constipation segments; accelerated private-label share and retailer-driven price cuts.

Which companies sell PEG 3350, and how does competitive intensity affect margins?

Featured snippet answer: The market is dominated by multi-brand generic manufacturers, private label suppliers, and a limited number of branded players. Competitive intensity drives low margins and prevents long-duration pricing power.

Competitive landscape characteristics

  • High SKU count and frequent list price reductions
  • Consolidation among generic manufacturers supporting scale sourcing
  • Contract manufacturing common for OTC laxatives and store-brand equivalents
  • Value differentiation limited to packaging convenience and label language

What commercial signals should be tracked for polyethylene glycol 3350 over the next 12–36 months?

High-utility monitoring checklist

  • OTC category pricing trends (retail shelf and wholesaler pass-through)
  • Pediatric formulation adoption (stick-pack and unit-dose penetration)
  • Private-label share growth in major pharmacies
  • Prescription channel share (Rx pulls can temporarily support unit economics where formularies restrict competitors)
  • Any brand-level litigation or reformulation announcements that could cause supply changes

Key takeaways

  • PEG 3350 remains a mature, off-patent laxative active with ongoing clinical work centered on pediatric and chronic constipation regimens, titration, and tolerability rather than novel pharmacology.
  • Market growth is driven by stable constipation incidence and pediatric usage, but revenue is constrained by ongoing generic and private-label pricing compression.
  • Exclusivity and patent-driven entry barriers are generally low for standard PEG 3350 powder products; differentiation is more likely to be label- and formulation-adjacent.
  • Revenue projections should be built on class demand and pricing compression rather than SKU-specific exclusivity timing.
  • Near-term business focus is package convenience, channel strategy (OTC vs Rx), and distribution scale more than innovation-led differentiation.
