Summary

What do they do? Harm Reduction Therapeutics Inc (EIN82-2380699) is the nonprofit manufacturer, distinct from Remedy Alliance and Harm Reduction Therapy Center. The public financial-support contact is not a retail checkout or verified restricted free-dose offer. No inquiry or gift was submitted. More

Why this approach interests us

  • HRT explicitly accepts philanthropic support for free supply, lower prices and production capacity; current partners distribute its approved OTC naloxone.

Our main reservations

  • No verified current marginal price, free-dose queue, linked-person reach or causal rescue increment. Existing free supply and public naloxone may replace most nominal output.

What do you get for your dollar?

Central national estimate: $255,604 donor and $357,846 gross-associated resources per10 QALYs. Bay estimates are $25,560,427 and $35,784,598; SF $127,802,137 and $178,922,991. Local shares are weak priors, not identified local results. Inspect formulas, inputs and sources.

Whole-gift portfolio

Allocate all charitable cash. Credit only assumed incremental free-access supply; retain other capacity and partnership costs without separate health credit.

Supply and placement

Subtract replacement of existing commitments, inventory, paid orders and other funding, apply capacity caps, then high-risk placement and a pooled packs-per-unique-person allowance.

Finite causal health

Compare the same people under baseline and temporarily improved effective rescue, integrating their survival difference once.

Scope of this review. One twin pack=two single-use3mg devices;24packs/case. Packs_per_unique_person is pooled supply per unique at-risk beneficiary over the funded interval, not a clinical dose recommendation, one rescuer=one patient, or one package=one overdose. Whole gift fractions sum1. Free-access cash price includes core manufacturer logistics/admin once. Remaining capital/price-access/partnership budget retained with no quantified additional health; not another same-core overhead haircut. Funding additionality subtracts substitution of already-financed free production, existing inventory, paid orders and other funders. Manufacturing cap limits extra output. Low inventory price alone does not imply supply bottleneck. Placement is last-mile arrival in high-risk networks. Packs per unique beneficiary absorbs repeated issues/sharing and stock per beneficiary; it is an unverified linked-person planning prior. Repeated responses do not generate another survivor tail. Both scenarios begin with the same unique at-risk people alive at intervention start. Delay discounts only. Recurrent nonfatal overdose leaves the person alive; fatal opioid hazard=event rate*fatality without effective rescue*(1-effective rescue). Other mortality is separate. Improved effective rescue only during finite funded protection; afterward both arms return to identical baseline mortality. Integrate the difference in whole-person survival once to finite horizon. No lifetime rescue multiplier, reduced drug use, MOUD or brain injury benefit. Effective rescue already includes witnesses, working supply, correct use, EMS and alternative naloxone; no separate98% observed-survival or formulation-efficacy factor. Rescue increment may be negative in a diagnostic access-displacement scenario. Positive incremental-dose demand is constrained not to exceed the available device pool; assumed devices per response is a modeling budget, not medical advice. HRT manufacturing and Remedy distribution estimates are alternative marginal-gift counterfactuals, not additive claims on the same naloxone chain. Distribution capacity is held at existing baseline for HRT. A combined portfolio must assign each linked person's incremental survival once; published HRT+Remedy QALYs cannot simply be summed. Gross associated outside costs per nominal pack cover only downstream distribution/training/storage/participant inputs not already HRT-paid. Full gift plus outside allowance retained even at supply null; not exhaustive net societal cost. No double production or shipping charge, medical savings or free-stock retail valuation. Signed rescue effect and gift-date PV harms allowed. Per-person acute harm is separate from survival utility; independent harm remains at zero activity. Positive ratios are null at zero/negative Q or nonfinite ratio. Bay/SF central shares1%/.2% are weak explicit national-program beneficiary-residence priors, not observed allocation or headquarters location. Nested0<=SF<=Bay<=US. Local-zero and larger-local scenarios expose uncertainty. National survival assumptions are not validated region-specific hazards.

2. Monitoring and information sharing

RiVive3mg nasal naloxone

FDA OTC approval. Supports opioid-overdose rescue action.

Our assessment. No manufacturer marginal deaths-per-pack or product superiority estimate.

19 selected Pennsylvania interviewees, variable denominators

Manufacturer-commissioned compensated qualitative interviews. Acceptability and reported experiences; no randomized mortality comparison.

Our assessment. No dose-use, unique-person, fatality or lower-withdrawal causal coefficient imported.

People after nonfatal opioid overdose

Historical adult Medicaid cohort. Repeat295/1,000person-years and fatal overdose1,154/100,000person-years; separate study all-cause778.3/10,000person-years.

Our assessment. Context for recurrent risk only. Model other mortality excludes overdose; cohorts are not current HRT or region-specific estimates.

Historical Massachusetts overdose-education/naloxone communities

Community interrupted time series. Mortality associations support plausibility.

Our assessment. Observational association not imported as individual rescue probability.

California statewide eligible distribution partners

Current DHCS public program documentation. Existing free nasal/injectable supply; generic nasal switch April2026.

Our assessment. Competing effective rescue and supply replacement, not absence of care.

3. Qualitative assessment

HRT explicitly accepts philanthropic support for free supply, lower prices and production capacity; current partners distribute its approved OTC naloxone.

Key reservations

  • Current $30 cost,70% allocation,35% supply additionality,60% placement and8pp rescue increment are unverified priors.
  • No current free-dose queue or actual unique linked beneficiaries; central geography1% Bay/.2% SF is particularly weak.
  • 2024 return shows $5,000 contributions and substantial sales; historic donor reliance is not evidence ordinary gifts fund all current production.
  • Reported PF operating expense $8,244,357 excludes $4,658,446 COGS. Combined $12,902,803 differs by $1 from reported direct charitable activity. No annual quantity permits current pack-cost inference.
  • HRT and Remedy health must not be added for shared people or stock.
  • Gross-associated resource allowance excludes unmeasured future medical and other budgets; no net societal ranking claim.

Benefits not included in our estimate

  • Price subsidy, manufacturing expansion and partnerships outside the credited supply tranche: costs retained, health unquantified.
  • No credit for historical product development, existing10% donation commitment, distributed inventory alone, or self-reported reversal counts.
  • No lifetime survival, reduced drug use, MOUD, infection, brain injury or speculative formulation-superiority credit.

4. What do you get for your dollar?

Expected unique-person survival, not deaths per pack

All clinical conversion and marginal funding values are explicit judgments. FDA approval supports the pharmacologic mechanism, not manufacturer-specific effectiveness. Existing public stock and EMS enter baseline rescue; funding substitution is separately handled upstream.

A better life is our comparison unit of 10 additional quality-adjusted life years (QALYs), potentially spread across people. These are uncertain estimates, not measured returns or verified donation offers.

How we calculate the estimate

Whole-gift causal chain: N=min(min(D*a/c*f,packCap)*placement/packsPerPerson,personCap); h0=other+events*fatality*(1-rescue0); Δh=events*fatality*Δrescue; Q=N*u/(1+d)^delay*∫₀ᴴ[exp(-h0*t+Δh*min(t,A))-exp(-h0*t)]/(1+d)^t dt − PV harms
N=245 expected people; national Q=3.912297655; gross resources=$140,000.

Uncertainty. Central estimates are a transparent conditional planning model, not evidence-based confidence intervals. Favorable assumptions move together; zero and harm remain possible. Inventory does not establish use, and expected unique-person counts are not observed.

HRT and Remedy are alternatives along a shared chain

The existing Remedy model uses a representative four-injectable-dose-equivalent distribution bundle, not a RiVive twin pack. Its procurement, last-mile constraints and causal units cannot be copied into this manufacturer model.

Joint-portfolio restriction: Combined health = survival gains for a deduplicated linked-person cohort, not Q(HRT)+Q(Remedy) for overlapping supply
No additive shared-chain benefit claimed.

QALY conversion assumptions
Counterfactual
Existing downstream capacity held fixed (range: Zero last-mile placement to favorable delivery). HRT gift changes supply conditional on baseline partner capacity; Remedy gift changes distribution conditional on its own supply baseline. Neither may receive independent full credit in a joint portfolio for the same person. Explicit boundary.
  • last_mile_failure: No placement, no supply-linked health. Resources remain. An arbitrary attribution haircut cannot replace specifying the actual bottleneck and joint counterfactual.

Do not sum either report with overlapping local naloxone cohorts. Count manufacturing price once; outside costs here exclude upstream costs already included in that price.

5. Funding and previous grants

Verify a supply-constrained, otherwise-unfunded tranche with downstream delivery and nonduplicated beneficiary exposure before treating favorable scenarios as an actionable opportunity.

No verified current quote or open funding tranche. Whole gift plus outside allowances remain even at null supply. Gross-associated resources include nonadditional downstream activity and are neither exhaustive nor net societal cost. Do not infer manufacture is currently the binding bottleneck.

This review does not establish a verified marginal funding offer or a complete history of grants.
