Teva’s Weltruza became the first once-monthly subcutaneous olanzapine, and it needs no post-injection monitoring

FDA approved Teva’s (NYSE: TEVA) Weltruza (olanzapine for extended-release injectable suspension) on 9 October for adults with schizophrenia, the first once-monthly subcutaneous long-acting injectable olanzapine. It comes in 318 mg, 425 mg and 531 mg doses, matching 10 mg, 15 mg and 20 mg of daily oral olanzapine, with no loading dose, oral supplementation or post-injection monitoring. The drug uses Medincell’s SteadyTeq copolymer technology and was filed as TEV-‘749 in December 2025. Teva expects US availability in the coming weeks, and the EMA accepted a marketing application in May 2026.

Approval rests on SOLARIS, a randomised, double-blind, placebo-controlled Phase 3 in adults aged 18 to 64, with an 8-week placebo-controlled period followed by 48 weeks on active doses. Teva reports improvements on PANSS, CGI-S and PSP but has released no effect sizes. Discontinuations due to common adverse events ran 5% against 4% on placebo, and Psychiatric Times reports no confirmed case of post-injection delirium/sedation syndrome across 3,971 injections in SOLARIS.

Access note

The existing intramuscular long-acting olanzapine carries a REMS requiring administration in a certified facility and three hours of monitoring after every injection. Without the three-hour wait, olanzapine depot can be given in the same appointment slot as any other monthly injection, which is where adherence programmes for schizophrenia are run.

  • The safety record is small but clean. No confirmed PDSS in 3,971 injections is reassuring, and the label keeps a PDSS warning because the syndrome occurred with intramuscular olanzapine and its rate with subcutaneous dosing is unknown. Real-world use will settle it.
  • Teva now has two SteadyTeq antipsychotics. Uzedy, its subcutaneous risperidone, uses the same Medincell technology, so Weltruza extends an existing franchise and sales force.
  • Metabolic risk travels with the molecule. Teva reports weight gain and metabolic changes consistent with oral olanzapine, and that is what payers and prescribers will weigh against the adherence gain.
  • Schizophrenia had two firsts in one week. Click’s Motivista, cleared four days earlier, addresses the negative symptoms that existing treatments mainly leave aside.

Click’s Motivista became the first FDA-authorised treatment for negative symptoms of schizophrenia, and it is an app

Click Therapeutics received FDA 510(k) clearance for Motivista, a smartphone-delivered prescription digital therapeutic for negative symptoms of schizophrenia, as an adjunct to clinician-managed outpatient care in adults with clinically stable positive symptoms, Fierce Biotech reported on 5 October. In the Phase 3 CONVOKE trial, published in JAMA Network Open, CAINS-MAP improved by 6.8 points against 4.2 on a digital control over 16 weeks (Cohen’s d 0.36, p=0.0003). Users spent about an hour a week on the app, and adherence through week 15 was 70.4% against 76.5% for the control. Boehringer Ingelheim handed full commercial rights to Click in April alongside a $50 million series D investment.

Access note

No price has been set, and Click says its rollout will follow coverage state by state because Medicaid covers a large share of adults with schizophrenia. A first-in-indication clearance reaches only as far as the Medicaid programmes that agree to pay for an app.

  • The comparator was active. A digital control makes the 2.6-point gap more credible than a waitlist would, and an effect size of 0.36 is modest but real.
  • Click is commercialising alone. Boehringer’s exit from commercial responsibility leaves a digital company building payer access without a pharma partner’s field force.
  • The category’s history is the risk. Pear Therapeutics filed for bankruptcy in 2023 after struggling to win reimbursement for its prescription apps, which is why Click is sequencing launch behind coverage.

Cerevance’s non-dopaminergic solengepras cut OFF time by 0.61 hours in Phase 3, entering a market that just added tavapadon

Cerevance reported on 7 October that ARISE, a 12-week Phase 3 trial of once-daily oral solengepras (CVN424) in 341 people with Parkinson’s disease and motor fluctuations on levodopa, met its primary endpoint. The 150 mg dose reduced average daily OFF time by 0.61 hours more than placebo (p=0.0350), from a baseline of 5.65 hours, and increased ON time without troublesome dyskinesia by 0.60 hours (p=0.0468). MDS-UPDRS Part II improved by 1.91 points against placebo (p=0.0008). Solengepras inhibits GPR6 in the striatal indirect pathway and does not act on dopamine receptors.

CI note

A 0.61-hour placebo-adjusted OFF-time gain is modest on its own, so the case rests on what comes with it. Discontinuations for adverse events were 3.5% in every arm, including placebo, and dyskinesia ran 4.4% against 1.8%.

  • Non-motor signals are the differentiator to test. Epworth sleepiness improved by 0.98 points and PDQ-39 by 2.87 points, both at nominal significance, against a dopaminergic drug class associated with daytime sleepiness.
  • The adjunct market just got more crowded. AbbVie’s Juvmo (tavapadon) was approved in late September and Lundbeck began a Phase II of Lu AF28996 this week, so solengepras will be positioned as the option that avoids dopaminergic side effects.
  • The filing package is the next disclosure. Cerevance plans to meet FDA on a potential NDA, gave no timing and named no second Phase 3.

Stoke aligned with FDA on a Vineland-3 composite for zorevunersen’s NDA, with launch targeted for early 2028

Stoke Therapeutics said on 5 October that it had completed a meeting with FDA to align on the planned US NDA for zorevunersen in Dravet syndrome, using a multicomponent analysis of four Vineland-3 subdomains: expressive communication, receptive communication, interpersonal relationships and personal skills. The NDA will rest on the Phase 3 EMPEROR trial, whose primary endpoint is major motor seizure frequency at Week 28, with five years of Phase 1/2a and open-label extension data also discussed. Stoke expects the readout in Q3 2027, a completed submission in the second half of 2027 and a potential US launch in early 2028. It holds US, Canada and Mexico rights, and Biogen has the rest of the world.

Regulatory note

Stoke is asking FDA to weigh development alongside seizures, the claim a disease-modifying antisense drug needs to separate itself from anti-seizure medicines. The CEO described FDA as showing willingness to accept the Vineland approach; the release lists no formal agreement.

  • On seizures alone the field is crowded. Fenfluramine, stiripentol and cannabidiol are approved in Dravet syndrome, so a label limited to seizure frequency would put zorevunersen among several options.
  • Data go in before the readout. Stoke plans to submit data throughout the first half of 2027, which shortens the gap between topline and a complete filing.
  • The designations stack up. Breakthrough Therapy in the US and China, orphan status in the US and EU, and Rare Pediatric Disease designation.

Shionogi paid $2 billion for IntraBio, about 29 times Aqneursa’s 2025 sales

Shionogi agreed on 5 October to acquire IntraBio for $2 billion, taking Aqneursa (levacetylleucine), approved in the US and EU for Niemann-Pick disease type C and, since September, in the US for ataxia in ataxia-telangiectasia. IB1001 is also in clinical programmes in CACNA1A-related disorders, GM2 gangliosidosis and spinocerebellar ataxias. Fierce Pharma, working from Shionogi’s disclosures, puts IntraBio’s 2025 sales at around $68 million. Closing is expected between November and December 2026.

CI note

The price is for the labels still to come. Shionogi is buying a molecule that keeps collecting rare neurology labels, and it bolts onto the rare disease unit Shionogi built around Radicava, bought from Tanabe Pharma for $2.5 billion in April.

  • The A-T label is weeks old. It rested on a 73-patient crossover study, as covered in NeuroPulse Week 38.
  • CACNA1A is the next test. IB1001-304 was due to complete enrolment in October, in disorders Fierce Pharma puts at about 30,000 US patients.
  • NPC is filling up. Two drugs are approved, and Rafael plans an NDA for Trappsol Cyclo after missing its pivotal primary, as covered in Week 40. The deal terms are in DealPulse Signal Week 41.

Lundbeck started a 150-patient Phase II for Lu AF28996 after open-label data showed 2.3 fewer hours of OFF time

Lundbeck presented Phase Ib data at MDS 2026 on 6 October for Lu AF28996, an oral prodrug of a D1-like/D2-like dopamine receptor agonist, in 34 people with advanced Parkinson’s disease and motor fluctuations despite optimised non-invasive medication. Over six weeks, Good ON-time rose by 3.6 hours and OFF time fell by 2.3 hours from baseline, while levodopa dose fell by 53.4%, and the 25 patients in the extension held most of the gain at Week 18. DARE2, a randomised, placebo-controlled Phase II in about 150 patients with Good ON-time at Week 19 as its primary endpoint, has randomised its first participant.

CI note

The target is the patient heading for a pump or a device. Lundbeck positions Lu AF28996 for people who would otherwise rely on invasive or continuous-delivery therapies, an oral option at the advanced stage.

  • Open-label numbers flatter. The changes are from baseline with no control arm, and Lundbeck calls them descriptive. DARE2 is the first controlled test.
  • Dyskinesia moved the right way. Troublesome dyskinesia fell by 1.2 hours at Week 6 and UDysRS by 14.5 points at Week 18, from a baseline of 28.3, which DARE2 needs to confirm against placebo.
  • Three mechanisms arrived within a fortnight. Tavapadon’s D1/D5 partial agonism, solengepras’s non-dopaminergic GPR6 route and Lundbeck’s D1/D2 prodrug all reported between late September and 7 October.

Genentech paid Alector $100 million for a preclinical brain-penetrant enzyme, 8% of a $1.27 billion headline

Alector granted Genentech exclusive worldwide rights on 5 October to AL-050, a preclinical brain-penetrant glucocerebrosidase enzyme replacement therapy built on the Alector Brain Carrier, for Parkinson’s disease and other neurodegenerative diseases. Alector receives $100 million upfront and is eligible for up to $1.17 billion in development, regulatory and commercial milestones, plus tiered royalties. Genentech takes on development, manufacturing and commercialisation, and Alector keeps the blood-brain barrier platform for its own pipeline.

Deal note

$100 million compares with $138.7 million of cash at the end of September, according to Fierce Biotech, and moves Alector’s runway guidance from at least through 2027 to into 2029. Alector licensed one molecule and kept the delivery platform that made it valuable.

  • The biology is GBA-linked Parkinson’s. GCase deficiency, tied to GBA mutations and alpha-synuclein build-up, is what the enzyme is designed to correct.
  • The clinic is undated. Alector dropped its 2027 target for first human testing in May.
  • Spur shares the upside. Spur Therapeutics receives a percentage in the teens of sublicensing milestones under the engineered GCase patent option, which Alector exercised by committing $15 million.

AviadoBio’s thalamic gene therapy raised CSF progranulin by 90% in its fourth dose cohort

AviadoBio presented ASPIRE-FTD Phase 1/2 data on 8 October at the International Conference on Frontotemporal Dementias for AVB-101, a gene therapy for frontotemporal dementia with GRN mutations, delivered by MRI-guided stereotactic infusion into the thalamus. Seventeen patients from nine countries have been dosed across four ascending cohorts. At 12 weeks, average CSF progranulin rose 36% over baseline in the third cohort and 90% in the fourth, and serum neurofilament light at 52 weeks was at or below baseline in the early low-dose cohorts. No treatment-related serious adverse events have been reported and no immunosuppression has been needed.

CI note

Progranulin is the target-engagement number every FTD-GRN programme is judged on, and AVB-101 shows a dose response. The neurofilament reading matters more: natural history suggests NfL rises by at least 13% to 14% a year, so a flat line in treated patients is an early sign of slowed neurodegeneration if it holds at higher doses.

  • Delivery is the differentiator. A one-time thalamic infusion aims for broad cortical reach from a deep relay, against the intracisternal routes used by other programmes.
  • Neurosurgery sets the ceiling on scale. AviadoBio is standardising the procedure across five expert neurosurgical centres.
  • Higher-dose NfL is the next read. Long-term neurofilament data from cohorts three and four are pending.

Aspen Neuroscience filed for a $100 million IPO to take its autologous Parkinson’s cell therapy into Phase 3

Aspen Neuroscience filed on 9 October to raise up to $100 million in a Nasdaq IPO under the ticker ASPE, Renaissance Capital reported. Its lead candidate, sasineprocel, is a single-dose cell therapy made from the patient’s own skin cells to replace lost dopaminergic neurons. Fifteen patients had been dosed in an open-label Phase 1/2a trial as of 18 August, and Aspen expects to dose a Phase 3 in the second half of 2027 following FDA feedback. Sasineprocel holds RMAT and Fast Track designations.

CI note

Autologous means one manufacturing run per patient, the trade Aspen makes against donor-derived cell lines: cells matched to the patient, against harder cost and scale.

  • The IPO is the financing test. A $100 million raise against a 2027 Phase 3 start shows how far public markets will fund regenerative neurology before controlled efficacy data.
  • RMAT is the regulatory lever. The designation opens discussion of accelerated approval on surrogate or intermediate endpoints, which matters for a single-dose therapy.
  • Watch the prospectus for durability. Fifteen dosed patients is the dataset investors will price, and how long the earliest have been followed is the number that matters.

Aurobindo won final approval for generic perampanel, a $67 million US market

Aurobindo Pharma received final FDA approval for perampanel tablets in six strengths from 2 mg to 12 mg, bioequivalent and therapeutically equivalent to Fycompa, Medical Dialogues reported on 5 October. The product is made at Unit-IV of APL Healthcare, a wholly owned subsidiary. IQVIA puts the US market at $67 million for the 12 months to August 2026, and Aurobindo plans to launch in the third quarter of its 2027 financial year.

Access note

Generic tablets bring the first price competition to perampanel. Catalyst Pharmaceuticals, which acquired Fycompa’s US rights from Eisai in 2023, holds the reference product.

  • Tablets only. The approval covers six tablet strengths; the report does not mention the oral suspension used in younger children.
  • Launch timing sets the curve. Aurobindo’s third fiscal quarter runs to the end of December, which puts a launch late in calendar 2026.
  • Aurobindo now holds 599 ANDA approvals, 574 final and 25 tentative, so perampanel is one launch in a deep generic pipeline.

A third of people on affected hormonal contraceptives were also prescribed an anti-seizure drug that weakens them

A study published in Neurology on 7 October found that, among 21,923 people with epilepsy prescribed hormonal contraceptives affected by enzyme-inducing anti-seizure medications, 7,154 (32.6%) had at least one overlap of 14 days or longer, lasting about seven months on average. The interacting drugs include carbamazepine, oxcarbazepine, phenobarbital, phenytoin and topiramate, and the affected methods include combined and progestin-only pills, patches, rings and implants. The study, led by Laura Kirkpatrick at the University of Pittsburgh, used prescription records and did not measure pregnancies.

Access note

Prescription records show the overlap; they cannot show whether anyone was warned. The right contraceptive exists for most people on these drugs, which is why the authors frame the fix as counselling.

  • Not every combination interacts. Some contraceptive methods and some anti-seizure medicines are unaffected, so the fix is a prescribing choice that already exists.
  • It falls between two prescribers. Contraception is usually prescribed outside epilepsy care, so the interaction sits between the neurologist and whoever writes the contraceptive.
  • Outcomes are the missing piece. The study did not examine pregnancies or contraceptive failure, and prescription data cannot confirm what patients took.
