`NoRMAN M. KA.l'LAN, MD
`The just-published sixth report of the Joint
`National Committee on Prevention, Detection,
`Evaluation, and 'freatment of High Blood
`Pressure (JNC vp is expected to be a widely
`used guidance for hypertension management.
`Dr. Kaplan-who served as chair of the
`section on treatment for JNC VI---reviews the
`report's drug therapy recommendations,
`noting changes from the JNC V report. The
`report's new rlsk-st:ratifica.tion guidance,
`·considerations for individualizing drug therapy,
`and advice on use of long-acting fonnulations
`.and combination therapy are presented.

`
`On a scale of 1 Oow) to 10 (high),
`HMOs gave their P1;3Ms an overall
`score of 6.2, down from 6.3 in 1996.
`That follows a drop from 7.2 to 6.3
`the previous year.
`Especially noteworthy ls that just
`50% of HMOs gave their PBM an
`. overall rating of 7 or higher in 1997;
`· whereas 61% did in 1996.
`Moreover, HMOs rated PBMs
`lower on almost all of ti:le 21 specific
`PBM functions evaluated. Many of
`
`the highest~rated functions were o~
`erational or administrative in nature,
`such· as pharmacy network adminis(cid:173)
`tration (rated 8.3) and claims p1'o~
`cessmg (rated 7.1), whereas more
`clinical functions (disease manage(cid:173)

`fared less well. The figu;re (see pre(cid:173)
`viouS page) presents average ratings
`for selected PBM functions.
`In a separate survey of 561 HMOs
`conducted in early 1997, PBMI

`found that just 45 of them Cm<:>stly

`"The development of drugs like
`ENA-713 should help break down
`the nihilism that surrounds the pro(cid:173)
`gressive degenerative process of this
`disease," said Howard Feldman, MD,
`. clinical associate professor of neurol(cid:173)
`ogy, University of Btitisli Columbia,
`Vancouver, Cariada, and an investi~
`gator in trials involving the drug.
`The reported fmdings are based
`on 6-month follow-up in 2,096 pa(cid:173)
`tients with symptomatic mild to mod(cid:173)
`erate Alzheimer's disease who were
`rando:mized to treatment with high-·
`dose (6 to. 12 mg/day) or low-dose
`(1 to 4 mg/day) ENA-713 or placebo.
`The mean .age of study parti~i
`pants was 73 years, and 94% had
`other illnesses requiring medication.
`All patients were participants in the
`3,300-patient ongoing Alzheimer's
`Disease with ENA-713 (ADENA) pro(cid:173)
`gram, the largest global trial of an
`Alzheimer's ·medication to date, and
`will be followed for up to 2 years. '
`Placebo recipients worsened on,
`the three primary efficacy measures,
`while patients assigned to ENA-713,
`particularly the high-dose group, ei(cid:173)

`
`Placebo group scores worsened
`by 4.15 points on the cognitive scale
`of the Alzheimer's Disease .Assess(cid:173)
`ment Scale (ADAS-cog). By contrast,:
`ADAS-cog scores improved by 0.79
`points in patients receMng ENA-713.
`"An annual 7- to 8-point deteri~
`ration on the AD AS-cog scale. i&
`characteristic in mUd to moderate
`Alzheimer's disease," .Dr. Feldmari:
`said. "Thus, the nearly 5-point differ..
`ence in scores between the tr:eat(cid:173)
`ment and placebo groups indicates
`a clinically relevant postponement in
`deterioration of roughly 6 months."
`He added that this magnitude of
`effect on ADAS-cog scores is the
`largest that has been reported for an
`acetylcholinesteraSe 'inhibitor.
`Benefit was also observed on the
`Clinician's Interview-Based Impres(cid:173)
`sion of Change (CIBIC) measure,
`which provides a global assessment
`of the patient's condition. Placebo
`group· srores decreased py a mean
`of 0.48 points while scores for the
`high- and low-dos~ ENA~ 713 groups
`decreased by .0.13 and 0.16 points,
`respectively (both significandy lower
`than the decrease with placebo).
`Scores on the third efficacy mea(cid:173)

`Deterioration Scale (PDS), were sig(cid:173)
`nificantly better in the high-dose
`ENAw713 group than in the placebo
`group at 6 months. ''This' finding is
`extremely important, because it con(cid:173)

`
`Dr. Feldman said. The PDS evalu(cid:173)
`ates quality-of-life changes.
`"These results mean that about
`30% of patients receiving BNA-713
`treatment will improve in terms of
`cognition, 'global functioning, and
`performance of routine activities, •·
`Dr. Feldman said. The. study also
`feund that benefits were greater in
`pati~ with more ·severe disease.
`The most common side effects
`seen with ENA:-713 in the trial were
`gastrointestinal in nature and were
`generally mild. and transient, rarely
`requiring treatment.
